New Prospect of Multiple Sclerosis Treatment
    
Multiple sclerosis is an autoimmune disease , the first clinical symptoms occur in young people. Clinically, according to the progression of multiple sclerosis can be divided into four categories , relapse - remitting : Relapsing-Remitting MS (RRMS), secondary - progressive : Secondary Progressive MS (SPMS), starting - progressive : Primary progressive MS (PPMS) and progressive - relapsing forms : Progressive Relapsing MS (PRMS). The progress of their disease can be briefly divided into two stages, relapse - remitting Relapsing-Remitting phase (RR phase) is mainly caused by the immune inflammatory response , and in the progressive stage progressive phase contains nerve degeneration. Immune induced inflammation is more specific mechanisms , and reaction mechanisms of degradation are still many uncertainties , so the current treatments have focused on the immune induced inflammation . FDA has approved a total of six kinds of drugs treating MS, can be divided into immunomodulatory agents Immunomodulator (Interferon-b 1a, Interferon-b 1b subcutaneously , Interferon-b 1a intramuscular injection , glatiramer acetate) immunosuppressants Immunosuppressant (mitoxantrone), as well as single polyclonal antibody (natalizumab).
 
Immunomodulatory agents:
    
Since 1993 Interferon - b 1b determined the efficacy of the MS , MS therapeutic drug development many of them move in this direction. Have been approved successively Interferon-b 1a ( subcutaneous and intramuscular two formulations ) and Glatiramer acetate (GA). GA is composed of four amino acids randomly formed polymer. Glatiramer acetate less common in Taiwan . Substantially Interferon - b therapeutic effect , can be reduced about 30% of the number of recurrences . However, its price is not Fei , takes about three a year , four hundred thousand . Interferon - b has the advantage of security.
 
Immunosuppressive drugs:
    
October 2000 was approved by the FDA for MS mitoxantrone treatment drugs . Mitoxantrone is an anticancer medicine, which has long been used to treat leukemia , prostate cancer, breast cancer , lymphoma and liver cancer. Mitoxantrone treatment of MS mechanism is in its broad immunosuppression , which inhibits T-cell and B-cell and macrophage proliferation , so that autologous antibodies to attack the central nervous system does not .Mitoxantrone in cancer month dose of 12mg / m 2, injection of 30 minutes. FDA approved for MS treatment usage per month 12mg / m 2, injection 30 minutes , this usage is based on the MIMS trial results. With Mitoxantrone pharmacokinetics of view , Mitoxantrone is a three compartment model, it will accumulate in the heart, liver , spleen and other organs, and slowly released, completely freed of three months or so. So every three months using is understandable . However, some studies have found that every three months using mitoxantrone, six months will have to be immunosuppressive effect, if the use of mitoxantrone every month just three months, so a more reasonable usage is that the first three months of the induction period induction phase with monthly injections 12mg/m2/month, and then in the maintenance phase maintenance phase every three months 12mg / m 2.Mitoxantrone restrict the use of the maximum cardiac toxicity, and the use of dose which , when the cumulative doses greater than 140mg / m 2 , the more prone to cardiac toxicity. Terms of use 12mg/m2 every three months to count , mitoxantrone only use up to three years , although the study found that there is still disabled immunosuppressive treatment within a year , an average duration of 30 years with MS perspective , mitoxantrone can use the term apparently too short.In addition to mitoxantrone, other immunosuppressants such as azathioprine, cyclophosphamide, methotrexate, mycophenolate mofetil, tacrolimus has a short-term experiments confirmed the efficacy of the MS . However, these drugs must monitor its side effects, such as cyclophosphamide can cause hemorrhagic cystitis, methotrexate even at low doses will cause liver toxicity , mycophenolate mofetil, tacrolimus and azathioprine bone marrow suppression.
 
Monoclonal antibodies :
    
U.S. FDA in November 2004 approved natalizumab ( trade name TYSABRI) used to treat multiple sclerosis. This is a new type of medication that belongs to a synthetic monoclonal antibodies. Multiple sclerosis lesions mainly by activated white blood cells ( such as T- lymphocytes ) through the blood - brain barrier (blood-brain barrier, BBB), into the brain tissue caused by an inflammatory response. The process must be drilled BBB leukocytes by adhesion molecules on its surface mating with intimal cells binding to accept the job . Natalizumab on with leukocyte α 4 - integrin binding , and thus disrupt the α 4 - integrin and vascular cell adhesion molecule vascular walls -1 (vascular cell adhesion molecule -1, VCAM-1) interactions , leukocyte like this more difficult to drill into tissue caused by vascular endothelial inflammation . In addition, it can also affect the α 4 - integrin with the extracellular matrix and parenchymal cells, the role of other molecules , thereby inhibiting the inflammatory cells to attract more . Can be found in animal experiments can indeed reduce the use of natalizumab into the brain parenchyma cells, white blood cells and reduces the MRI detected lesions.In clinical trials , TYSABRI once every four weeks to implement intravenous injection relative to the control group decreased by 66% the number of episodes per year (0.25 vs. 0.74). Track of the year the treatment group compared to 76% of the attack , the control group was 53% ; NMR of new lesions in the treatment group also had significantly reduced. Also in an original in the use of Avonex ( one kind of beta interferon ) plus TYSABRI patients in the trial, also seen in relapses and MRI have a significant effect. For long-term use are in safety or efficacy have changed there is still no adequate information . Patients currently receiving treatment in <1% of patients have a strong allergic reaction.Alemtuzumab is a CD52 antibody . rituximab (Rituxan) for the CD20 α b antibody , daclizumab (Zenapax) compared with interleukin 2 receptor α -chain antibody .In summary , this new type of drug for multiple sclerosis This provides another intractable diseases the treatment of choice . Its long-term efficacy are inconclusive , must wait for more clinical experience accumulated only conclusion.
 
Statins:
    
Statins are HMG Co-A reductase antagonist , used to lowering blood pressure is well known . It is used in the treatment of MS is because in vitro findings , Statins can inhibit T-cell and B-cell activity , there are many possible mechanisms . Statins now been confirmed in the theoretical stage , to use in the treatment of MS remains well-designed experiments to confirm , particularly cholesterol in the general dose of whether the effect of this immunosuppressive , still worth progress discussed.
 
Estrogen:
    
The researchers found that when the patient pregnant , MS seizure frequency reduction , especially in late pregnancy , but also in production within a few months after the attack. The fetus in the mother during pregnancy can be considered a foreign object , in order to smooth the fetus in the mother survive the womb of the immune system has made ​​some adjustments. Based on these observations , to infer that estrogen may mediate the immune system is one of the hormones . There is also a small study included 12 RRMS not pregnant women , daily use of estriol 8mg, found that after six months developing MRI lesions decreased. When estriol after disabling , lesion number has increased . Despite its estriol treatment of MS theory, but to use in MS patients , which can cause endometrial hyperplasia , breast cancer, vascular effects on the heart , are to be included in the next major experimental considerations .
 
Conclusion:
    
MS is a disease requiring long-term war , so in addition to the development of therapeutic efficacy , but also need to consider the long-term safety and convenience .

Treatment of multiple sclerosis

With physicians to establish a good doctor-patient relationship is very important. However, to find a good doctor seemed to get along is not so easy. Not all physicians are equally suitable for a certain patient . Family physicians to develop the disease process is for general medical care , but multiple sclerosis is not a "normal" diseases. Multiple sclerosis patients really need his own physician, physiatrists specializing in rehabilitation for multiple sclerosis disposal an increasingly important role , especially in patients with significant disabilities , need more physiatrists assistance. Often, however, the treatment of multiple sclerosis is tracking neurologist . Not all neurologists are the same, although all have been neurology specialist training in the differential diagnosis of neurological disorders , however diagnosed when the disease has been established , many neurologists are not good for long-term care , or not interested. Multiple sclerosis patients can require a long struggle with him a physician . Easy to say , but really want to find a professional caregiver , is not readily available . When looking for physicians , there are some factors to be considered. All doctors want to help patients , but due to the relationship between personality traits , some people with certain physicians is " substandard ." Some patients want physicians clearly told him how to do it , some people want another medical procedure can have a wide selection to a decision by himself . These approaches do not who is superior , but different views of patients and physicians get together , a doctor is not a pleasant experience it. So, try to understand what kind of personality he is a person , to find your " to come together ," physician . Patients who do not need to dominate the overall treatment process , not everything required to do according to their meaning ; patients are just understand that he has the final authority and honest with your doctor clearly explain , so there is usually the most good doctor-patient interaction. Another thing to remember is : a good physician is usually very busy, the number of patients are also many, especially physicians every patient wants to spend time take care of him , but the doctors have so much time to do so ? Therefore, it is best to look at before physicians to ask questions first think well, written on paper , lest temporarily forgot to ask . In addition, it is best to remember that all drugs are taking their names and doses . Not all doctors do everything, do not expect physicians to solve all problems. Patient to the physician to have a reasonable expectation . There may be a town in which you live , there is no a physician meet all your needs , If so, had to go to other cities and counties . You can also ask the other patients the same disease , which side we need to have your good physician . Your physician may be useful to you the medicine , it may not help. Do not have a default position to identify all of the drug " is not natural ", " useless ." Do not eat medicine , there is a clear therapeutic purposes, we take medicine ; however appropriate prescription drugs through physicians , we should not be afraid to take medicine . Large individual differences in multiple sclerosis , a treatment program either have no way to apply to all patients.Medications
    
Treatment is mainly carried out in two aspects , one is delaying the deterioration of multiple sclerosis , the other is on the current symptoms , treatment.1 treatment slowed progressionIn recent years for relapsing forms of multiple sclerosis research, has invented some new treatments . The first method is to use a beta- interferon (beta interferons). Interferons are produced in vivo response to external stimuli out of the protein . For example, when a virus infection, the body will produce interferon . These interferons may affect the immune system. Interferon can be divided into three categories: A (alpha), B (beta) and C (gamma). IFN will be excited to the immune system, making the trip even more deterioration of multiple sclerosis . Interferon beta tends to calm the immune system , is good for multiple sclerosis . First listing of beta interferon Beta interferon-1b ​​( in the United States called Betaseron, other areas of Betaferon). Subsequently Beta interferon-1a (Avonex, Rebif) also followed the market. Beta interferon to reduce the frequency of recurrence , onset extend the time between onset and reduce the severity of the attack . The various effects are cumulative damage can be reduced . Nevertheless , interferon does not make the cause of disability better. Interferon just let the disease stabilized it. It is not a perfect drug , even the drug is being used may also be patients and allows the subsequent onset of a certain degree of deterioration in condition . Though who fit with interferon is still controversial, but it is clear that interferon may indeed affect the disease process of multiple sclerosis .Many patients with relapsing forms of multiple sclerosis , without immediate use of interferon ; because they may own course quite stable , no need to spend the money and withstand the possible side effects . Frequent episodes in patients only need to use this medicine. Since these two B -shaped dose interferon titer is not the same way , there may be one in some patients respond well , other patients for another better response . As for what kind of use , it would allow the physician to vexing enough.Both interferon therapy at the beginning of time have side effects . Possible side effects include fever , fatigue, and nausea . Location of the injection may cause skin reactions. Some users may be accompanied by depression . All the above effects are processable .Some patients with relapsing forms of multiple sclerosis , as side effects are too severe or ineffective , requiring "non- interferon " of treatment. Then Glatiramer acetate (Copaxone) is another option . This drug requires daily subcutaneous injection, studies have shown that this drug may also reduce the frequency of attacks , and may reduce the MRI abnormalities seen on the number .To emphasize that these expensive drugs , not every multiple sclerosis patients are needed. Deciding whether or not to use these drugs are not so straightforward simple , should have knowledge in this area and physicians have a good discussion and then decide .Other immunosuppressive agents : the use of immunosuppressive agents to reduce the immune function to reduce damage to myelin . Such drugs are Azathioprine, Cyclophosphamide, Methotrexate Cyclosporin, but should pay attention side effects.
 
(2) to treat the symptomsSymptomatic treatment of multiple sclerosis has been disposed of trunk. Symptoms of multiple sclerosis can be divided into the brain and spinal cord demyelination direct cause, and not the direct result of demyelination . Symptoms caused by the disease itself is called primary symptoms (primary symptoms), such as the site of the loss of myelin sheath tube movement , causing no strength . Loss of coordination and balance tube site of myelin , causing incoordination . A feeling of loss of myelin tube parts , causing numbness, pain , burning , or itching and other symptoms of flu science . Not difficult to imagine a combination of these symptoms are numerous , it is no wonder no two patients with multiple sclerosis symptoms are exactly the same. With primary symptoms, sometimes sub -onset complications. Secondary symptoms refers indirectly caused disease symptoms. For example, patients with stiff limb weakness , range of motion in the affected area becomes smaller , the formation of joint contractures , and long-term lack of activity , causing osteoporosis or fragile skin . Chronic disease may also alter individual perception on life , as well as the attitude of the face of pressure , resulting in depression, frustration , or career and marriage problems . These symptoms are referred to as three symptoms (tertiary symptoms). Therefore, patients with multiple sclerosis have to face , not just " a disease " so simple only. Really want to deal with multiple sclerosis, and should have to deal with their symptoms , improve physical function , and improve quality of life .o cramps :Spasm is stiff (stiffness) of the mean. When demyelination occurs in the nervous system associated with the regulation of muscle tone of the site , the result is often stiff or spasm. Because the brain and spinal cord have a lot of nerve and muscle tone , and therefore patients with multiple sclerosis spasticity is a very common problem . This rigid symptoms are usually very mild and do not cause special problems. In fact, patients sometimes need to provide stiffness and spasms , to help him to stand or move . But sometimes , stiffness, pain may be hard to level , and interferes with daily life .Spasticity• treatment of spastic exacerbating factors - infection, pain , Popi .• Perform complete stretching exercise program , including active and passive stretching.• Use the necessary corrective aids .• Drug• do not respond to drugs severe cramps, consider surgical treatment .Spasm drug treatment often good results. Baclofen acts on the spinal cord nerves controlling muscle spasms . This is the most used anticonvulsant drugs , the majority of patients a good response to this drug . Dosage should be based on the individual patient's condition carefully adjusted. No effect dose is too low , the dose is too high, it will produce a feeling of fatigue and weakness . Because the balance upright posture and require some degree of muscle tone. Baclofen is often used from the beginning to use smaller doses and gradually increase the dose until the maximum effect. Use this drug the most common mistake is too early to give up, a moderate dose has not added enough muscle relaxation was stopped . For Baclofen response , individual differences, some as long as 5 mg pills a day, a half stars is enough, someone will have time to eat eight , four times a day to eat enough . Tizanidine (Sirdalud), which is a newer anticonvulsant drugs , although effects in the spinal cord , but Baclofen role in the different regions. Compared with most other drugs , it reduces the ability of stiffness and spasms favorably , and less impact on muscle strength. However, this drug must be carefully and slowly increase the amount , because if the dose is increased too quickly , the patient will be very sleepy . Starting dose is 2-4 mg per day , the maximum daily dose is 36 mg. This drug is quite effective in difficult to treat patients who can be used with Baclofen and use . Other drugs, including diazepam, clonazepam , etc.Fatigue :o very surprisingly , patients with multiple sclerosis , the most difficult daily life can cause symptoms of fatigue. But for the patients themselves , this is not surprising . Fatigue is very often occurs , there are many types. Treatment strategies, including moderate exercise and rest . If a man has lost its ability to muscle atrophy and conditional (deconditioning) will ensue . This is another source of fatigue . Maintenance activities is necessary. For this fatigue exercise and proper disposal strategy is to maintain activity . Depression (Depression), may be accompanied by multiple sclerosis occurs, and cause significant fatigue. The reason for this may be because of appetite, sleep , or systemic depressed feeling. For this type of fatigue is basically going to understand it, a positive acceptance of antidepressant medication and psychotherapy . Multiple sclerosis patients with the most common fatigue , is called burnout (lassitude). Burnout is characterized by the gratuitous wanted to sleep in the daytime . This fatigue may be caused by the biochemical reactions . Certain changes in the chemical reaction of the drug in the brain , which may help this situation . For example Amantadine (PK-Merz), which was originally a type A influenza epidemic anti- viral drugs , but can also act on the nervous system. The newer antidepressants , including fluoxetine, paroxetine, and sertraline, the effect of this malaise has , even for people without depression are also effective . For moderate to severe fatigue symptoms, save energy, occupational therapy may help. Efficient completion of daily routine matters , such as dressing , washing , toileting , eating , etc., can leave some more energy to do other activities .
 
o optic neuritis : often accompanied by pain in the eye , then there may be waning vision or even blindness , then injectable Steroids such as methylprednisolone followed by oral Steroids, sometimes vision can accelerate the recovery .o Pain: multiple sclerosis patients have experienced varying degrees of pain . Muscle pain , back pain can aspirin or acetaminophen treatment. Chronic pain such as needles tingling or burning sensation is difficult to treat , antiepileptic agents and antidepressants are also part of the analgesic effect.o bladder dysfunction : the disease process , patients due to poor nerve conduction , may not be saved or not fully voiding of urine , bladder dysfunction caused by prayer situation. General use of anti- cholinergic agents Dukes B ( such as Oxybutynin or propantheline) therapy. A small portion of patients should be inserted into the catheter to help urinate.3 The treatment of relapseo steroids , including : Solu-Medrol, (methyl-prednisolone), Decadron (dexamethasone), prednisolone , are still used for acute exacerbation of multiple sclerosis or acute exacerbation . They have little effect for multiple sclerosis itself , but can be made to reduce inflammation of the nerve function and rapid recovery . These drugs may have side effects, including : fluid retention , weight gain , diabetes, cognitive function , acne , peptic ulcer , osteoporosis, and cataracts. Steroid treatment may be obvious , but these drugs should be aware of these drugs by the physician to prescription use only appropriate . According to the patient's condition , steroids may be administered orally , intramuscularly or intravenously administered to . Best not for a long time continuous use of steroids , because of side effects may quickly accumulate .oMultiple sclerosis often in young people who attack, affecting the patient's family, work and life. Patients should pay attention to emotional stability , develop some hobbies, and try to hold a positive attitude . So as to enjoy a more abundant life , and more likely to be symptomatic improvement .

Truth multiple sclerosis

Truth multiple sclerosisOn a global scale , multiple sclerosis (MS) is the most common group of young people caused by neurological diseases, medical workers are still unclear the exact global multiple sclerosis incidence , but also its causes unclear , at present, multiple sclerosis is still no definitive cure .
 
However , in order for patients to truly understand the disease and improve the patient's quality of life, scientists conducted a multifaceted and multiple sclerosis, a lot of research .This section, you will learn a lot about multiple sclerosis detailed and useful information , including the possibility of disease pathogenesis, diagnostics , and if it is diagnosed as multiple sclerosis , your doctor may ask you to say something like .This section tries to tell you about one of the most comprehensive knowledge of multiple sclerosis , give you the most comprehensive want to know about all aspects of multiple sclerosis .What is Multiple Sclerosis ?English is the Multiple Sclerosis Multiple Sclerosis, often referred to as MS, lesions in the brain and spinal cord , is a common non-traumatic central nervous system diseases.CNS fiber surface covered with a substance called myelin , which has neurotransmission effect and protect nerve fibers . The body's own immune system attacks and damages the myelin will lead the occurrence of multiple sclerosis . In the inflammatory autoimmune reaction is stopped after numerous damaged nerve fibers scar formation , we call " hardening " , sometimes also called a " patch " or " injury ." Because the disease in many places throughout the central nervous system appear randomly , so multiple sclerosis means " many scars " means.
 
Meanwhile , multiple sclerosis is a chronic disease , there is a course of intermittent episodes . Multiple sclerosis (MS) mainly in the young adult population incidence , onset of each person varies considerably , each person presenting symptoms are also very unique . Many aspects of the disease is currently unexplained . The exact cause of the disease remains unknown , do not know how to prevent disease. Meanwhile , the world has invested a lot of energy research multiple sclerosis, although this has not found a method that can cure MS . However , the relevant process can greatly improve disease emerging drugs , these drugs can delay the development of the disease which greatly improved the quality of life of patients .
 
Who will suffer from multiple sclerosis ?Worldwide there are an estimated 1.2 million people suffer from multiple sclerosis (MS). Anyone, no matter who they are, no matter where they live , are likely to suffer from multiple sclerosis.Genetic and environmental factors on the risk of disease play a role .Multiple sclerosis occurs in northern Europe , North America, Australia and New Zealand southeast . Tropical and subtropical regions rarely sick .Multiple sclerosis (MS) occur in women, relatively few men ,20- 40 years old -prone , with an average age of onset is 31-33 years old. Few children or elderly people suffering from multiple sclerosis.RaceMultiple Sclerosis in Caucasian populations , namely white masses incidence was significantly higher than other ethnic groups. Moreover , the study found the incidence of high risk youth . If , one born in low-incidence areas, such as the Asian individuals before the age of 15 to a high incidence of migration areas, such as northern Europe, greatly increases the risk of disease .Age and multiple sclerosisAlthough the average age of diagnosis of MS is about 30 years old, but multiple sclerosis (MS) can be any age . There are less than 4 % of patients when the disease in children . Incidence in women and more children , the main symptoms of sensory dysfunction symptoms, relapse - remitting multiple sclerosis is the most common.Sex and Multiple SclerosisWomen suffering from multiple sclerosis two times more likely than men , the only exception is , primary progressive multiple sclerosis incidence probability men and women are the same. Men once the illness , the disease is often more severe than that of women , the prognosis is worse.

The epidemiology of multiple sclerosisPrevalence of multiple sclerosis in the global distribution is uneven, according to zoning, there are the following three common areas :High incidence ( per 100,000 population prevalence > 30 people ) - these regions of Europe , including the European part of Russia , Canada, the northern United States , southeast Australia and New Zealand.Middle region ( 5-30 per 100,000 people get sick ) - These areas are the southern United States , most of Australia , South Africa and the southern Mediterranean countries , Russia, Siberia , Ukraine, and parts of Latin AmericaLow-incidence areas ( less than 5 per 100,000 people get sick ) - these vast regions of Asia , Africa, northern South AmericaWhen a person from the disease migrated to a low incidence area high incidence of multiple sclerosis may increase the risk of illness . Although there has been no definitive evidence that environmental factors are the main reason for MS pathogenesis , but scientists generally believe that environmental factors in the pathogenesis process plays an important role . Scientists have discovered the epidemiology of multiple sclerosis from low latitudes ( equator ) gradually increased to the high-latitude features . Multiple sclerosis (MS) in the Caucasian population ( white race ) is more prone than other races , even so, living in high- latitude countries and regions Caucasian populations than those living in low-latitude countries Caucasian incidence. For example, the prevalence of MS in Scotland than in England with a country / Welsh high , the reason may be located in Scotland , England / Wales, the north, higher latitudes . In addition , in the different regions of Scotland , the most southern Orkney and Shetland region is the world's highest prevalence of multiple sclerosis, one of the areas , which may be a genetic susceptibility to multiple sclerosis .

MS is caused by reasonsMultiple sclerosis (MS) is widely considered to be an autoimmune disease, meaning that their immune system can not accurately identify own cells and foreign cells attack and destroy its own tissues . Such self- organization is the nerve myelin in the central nervous system . These nerve fibers wrapped in myelin , and become immune cells attack the body of the object.Other factors include genetic, viral , environmental factors also cause the onset of multiple sclerosis .


Multiple sclerosis (MS) symptomsSymptoms of multiple sclerosis in a different between patients may vary greatly. Completely different symptoms depending plaque or damage parts of the central nervous system . For example, parts of the optic nerve damage can cause optic nerve disorder , damage nerves in the spinal cord can lead to weakness and upper extremity , lower extremity sensory loss .Sensory disturbancesForeign data show that one-third of patients with multiple sclerosis is the first symptom of sensory dysfunction , which is some strange feeling , such as numbness , tingling , or an area of ​​the body to lose feeling. These symptoms are often asymmetric : they may appear in a hand or a leg , or the trunk showing the distribution star ."Mobility feel" or a major joints obstacles and torso straps feeling is common symptoms. In some other cases has been reported in patients under the current will pass from the back feeling. This phenomenon is called the phenomenon of L Hatch
 
Visually impairedMultiple sclerosis is one of the most common symptoms of visual impairment . Symptoms include blurred vision , which can be extended to the side of the eye loses vision ( mainly as a transient single-blind ) , and even the eyes are involved on both sides ( double-blind ) .Can not be corrected by glasses vision loss can occur .If the nerve demyelination around the eyes , can cause double vision , which is one of the symptoms of multiple sclerosis -related vision .When nystagmus, visual disturbances sometimes cause dizziness .If you squint , then the eye will occur unconsciously fast reverse movement.
 
Vertigo and coordinationDizzinessVertigo ( dizziness ) accompanied by weakness, or endure a kind of dizzy or shaky feeling. Vertigo is because the imbalance and damage.Coordination DisorderCerebellar coordination disorder usually because of nerve fibers have been damaged : Located above the cerebellum part of the brain stem that control movement balance and coordination. Coordination disorder may lead to some specific sport does not work , for example, can not be completed successfully lift the cup action . In some cases, will be accompanied by convulsions , so that more action could not be completed toast .Some patients may sit, stand, walk were difficult , medically known as ataxia . Voice disorders that of dysarthria, which speak not continuous, or slow , pronounced hesitation , sometimes occur aphonia .
 
DyskinesiaDyskinesiaOne symptom along with the development of multiple sclerosis , will gradually become the main symptom , it is not at liberty to move the limbs . This is the performance of movement disorders . Movement disorders has led to loss of muscle strength and tone . Medically known as spasticity .Secondary symptoms may include walking problems ; walking for a long time , the legs become heavy , as if nailed to the floor ; games will be slow ; stair will become very difficult.Legs will gradually become stiff and weak, which is the main symptom , one leg may appear drag on bumpy ground, were difficult to maintain balance. Premature muscle fatigue . Limb weakness and stiffness ( spasticity ) may be aggravated .SpasmSpasm was under pressure and pain affect climate . As complex spasms , rhythmic , involuntary twitching and trembling usually do a very simple action, such as heels , you may occur.Most patients experienced several episodes , the rhythmic twitching stops . Despite sporadic convulsions still occur , but you can transform the position of body parts to improve these convulsions. For example , you can step on the feet firmly on the ground .However, in the evening, some patients still occur painful leg muscle spasms or cramps.Bladder dysfunction
 
The frequency of occurrence of bladder dysfunction and disease at different stages of development , but also on the degree and obstacles .The most frequently heard complaints are: patients need repeated compulsive urination, urgency, dysuria and urinary flow interruption .As the disease increased, may lose control of bladder function caused by urinary incontinence or bladder emptying weakened cause urinary retention , urinary tract inflammation caused by infection.
 
Sex lifePatients suffering from multiple sclerosis may experience some sexual problems in life . These problems include impotence, decreased pleasure during intercourse , or inadvertently muscle tension.Mood changesPatients with multiple sclerosis in a bad mood , there will be changes, including depression, lack of self-esteem, is the most common clinical depression . Once the diagnosis of multiple sclerosis , the patient will have a depressive reaction , or one of the symptoms of multiple sclerosis .FatigueMultiple sclerosis fatigue caused by a rapid onset of fatigue unique . 70% of multiple sclerosis patients in the disease process more or less will experience fatigue, fatigue in body and spirit would have been apparent over- tired .The progress of multiple sclerosisAn unpredictable diseaseMultiple sclerosis is an unpredictable disease, and progression of the disease is not an identical model. Course of the disease , the type and severity of disease , dysfunction occurs in the order may be different for each patient , so the diagnosis of multiple sclerosis , it is impossible to predict the disease 's progress.Because of the unpredictability of the disease , so to predict to what stage the disease will develop , or whether the disease is very difficult to maintain stability .Meanwhile, patients and between patients with disease manifestations are also very different .Most multiple sclerosis has a normal and near normal life expectancy.Drugs, such as changing the course of a number of drugs (DMD drugs) , can help patients have a complete vibrant life , alleviate symptoms of the disease most important , the slow progression of the disease .There are four types of multiple sclerosis : relapsing - remitting , renewal progressive , primary progressive and benign . Four types of multiple sclerosis may reach the level of progress of disability not the same , the following will be explained in detail .Typical characteristics of multiple sclerosisMultiple sclerosis is one of the biggest characteristics of recurrence , a new symptoms appear or existing symptoms worse , and lasted 24 hours. In general, the symptoms develop will last a few days , and then the next 3-4 weeks remained relatively stable , about a month after symptoms.Need to know about each of the different types of multiple sclerosis characteristics , you can click the following link.The following information is included for each stage of development of the disease the general summary.Relapse - remitting multiple sclerosis
Relapse - remitting multiple sclerosis (RRMS) is the most common one multiple sclerosis type ( accounting for almost all cases of multiple sclerosis for 40% ) . Relapse - remitting multiple sclerosis patients are unable to predict when the onset of the disease , or when it will be what kind of new symptoms. But in the two attacks can be fully restored to " normal" ( so-called remission ) . During remission , onset of symptoms occurred period more or less improved.If relapse - remitting multiple sclerosis patients had deteriorated condition after each attack , but recurrence between the two conditions remain stable , then it is called the " worsening relapsing - remitting multiple sclerosis ."Relapse - remitting multiple sclerosis disease process is in progress , and foreign data show ,10- 15 years later, almost 75% of remission - relapsing multiple sclerosis will progress to renew - progressive multiple sclerosis (SPMS).References1.

Brain 1989; 112: 133-46.Renewal - progressive MSThe case without treatment , about 50% of relapse - remitting multiple sclerosis (MS) will be in 10 years the development of secondary - progressive MS, formally known as chronic progressive MS.Some secondary - progressive MS can have seizures, but many people may not have seizures. At this time , the patient's symptoms and disability is going through a process of gradually increased .15 years later, was diagnosed with secondary - progressive MS patients , some people need to use a cane to walk , while others may need to use a wheelchair .Primary progressive MSPrimary progressive multiple sclerosis (MS) patients' symptoms begin self-diagnosis , the symptoms gradually began to deteriorate , however, no significant ground attack. In later months or years, will stabilize or continue to deteriorate.Primary progressive MS is a form of disease progression , relapse and remission is not clear . Such patients suffering from multiple sclerosis with age more often than other types of multiple sclerosis patients to be large ; 40 -year-old primary progressive MS is a good age ( young people rarely suffer from this type multiple sclerosis ) .Unlike other types of multiple sclerosis, primary progressive MS pathogenesis of male to female ratio is almost the same. The initial symptoms of this disease is usually gradual deterioration of spastic gait , followed by a decline in walking ability . Primary progressive MS prognosis than other types of multiple sclerosis usually poor condition deteriorated quickly. The exact diagnosis of primary progressive MS is difficult.Because the typical primary progressive multiple sclerosis, spinal cord lesions occur in parts of brain magnetic resonance imaging (MRI) images may not show any damage typical of multiple sclerosis , therefore, in order to accurately diagnose primary progressive multiple sclerosis, spinal cord MRI scans are necessary checks.
 
Benign MSBenign multiple sclerosis (MS) has a relatively mild symptoms uncommon paresthesia, can be completely recovered. After a once or twice after the attack , may be accompanied by a complete recovery with no disability occurred .This type of multiple sclerosis will not deteriorate over time , it will not appear permanent disability , disease would not be progress . However, some benign multiple sclerosis patients will eventually have disease progression ; 10-15 years starting from the onset of multiple sclerosis will evolve into advanced stage .Benign MS is the most rare type , only 10% of the patients were diagnosed as benign MS.Benign MS does not occur when the onset of the symptoms of vision loss , without any symptoms of movement disorders , such as diplopia, coordination difficulties , or tremors.Benign multiple sclerosis only after the onset of 10-15 years have had minimal disability in order to be properly diagnosed .Prognostic factorsAlthough there is no standard model of multiple sclerosis , but the long-term development in the disease process, and outcome of the disease there are still some very positive factors affecting the prognosis of the disease .n If within 5 years after the onset of slight damage, 2/3 of patients with multiple sclerosis in 15 years time will remain relatively stable ;n If you have a disability in the rapid onset occurs, then after 15 years will occur in significant disability.
 
The following signs indicate the disease will have a benign course :l The initial symptom is a feeling or vision disorders ;l between disease onset complete remission ;l 5 years without disabilities occurred ;The following signs appear presages course of evolution is not optimistic:n diseases when there is paralysis symptoms ;The initial stage of the disease , there n sustained loss of function ;n older when the disease ;n disease process have frequent attacks.Other features on the multiple sclerosisn Multiple sclerosis is not a fatal disease , only a small number of people will die from complications caused by advanced multiple sclerosis ;n patients with multiple sclerosis life expectancy of people with and without suffering from this disease is similar ;n About half of the course of disease is relatively benign, and there is no occurrence of severe functional limitations .
 
Diagnosis of multiple sclerosis

 
In the implementation of the multiple sclerosis treatment , you must confirm the diagnosis.Only the exclusion and MS have the same symptoms of other diseases can be diagnosed after MS.
 
Complete medical examination is very important
 
Currently, there is not a very clear means of checking the exact diagnosis can someone suffering from multiple sclerosis.Multiple sclerosis is difficult to diagnose because the symptoms of patients with diverse , cross each other combination of these symptoms , making the clinical manifestations of MS patients is more complex unorganized , patients, and patients with symptoms of the difference between very large .Because early symptoms may appear on a variety of other neurological diseases , therefore, requires accurate diagnosis of multiple sclerosis neurologist has a very extensive clinical experience . Requirements neurology experts to conduct a comprehensive patient history taking as well as some specific examinations, including neurological examination , and correct assessment of test results, draw the right conclusions .Multiple sclerosis is only in the exclusion of all other possible diseases before the correct diagnosis.
 
How to diagnose multiple sclerosis ?
 
The first symptoms of the disease law , or often just arms for short leg discomfort , but no other significant changes . Patients and doctors can not I which the diagnosis of multiple sclerosis . May be in a few months or even years later , be possible to accurately diagnose multiple sclerosis.
 
Diagnosis should be based on clinical manifestations and laboratory basis.The importance of clinical diagnosis depends on medical history , or past history, and clinical neurological examination.Subclinical diagnosis is based on the results from the laboratory tests , such as magnetic resonance (MRI), evoked potential (VEP), cerebrospinal fluid (CSF).Once a diagnosis of multiple sclerosis, the results are often people feel very depressed , it may cause the patient intense disappointment , pain, shock , fear and grief , these are normal reactions.In fact, in the diagnosis of multiple sclerosis , you should try to find a neurologist or nurse talking to seek how to deal with and the best way to treat multiple sclerosis and support . Can and have been suffering from multiple sclerosis patients through patient will respond or forum for the exchange of experience in MS disease .
 
What is MS relapse ?The logo is a diagnosis of multiple sclerosis disease recurrence and the original symptoms intensified.MS relapse is defined as: In the absence of signs or omens like the case of the emergence of a new symptom or symptoms of recurrence old and lasted for more than 24 hours.Recurrence and worsening the duration and course of the disease process associated with little or can be predicted in advance . Recurrence can develop several days and lasts 3-4 weeks and then a month later , the slow recovery.Neurological examination is how is it ?Neurological examination is the function of the nervous system for inspection and testing.Cranial nerve examinationBrain examination is to check the efficiency of facial movement and visual ( eye movement ) . We are more familiar with the ophthalmoscopy , can be used to observe the fundus painless , fundus is part of the optic nerve enters the eye .ReflexReflection is the nervous system to external stimuli involuntary reaction . Reflex is to use a rubber hammer to tap the inspection site . For example, the knee-jerk reflex is in the muscle tissue relaxed state , below the knee with a rubber hammer tapping parts of the lower limbs caused by involuntary bounce .One side of the body becomes weak reflection , deletion, enhanced or abnormal reflexes. Graze the skin leads to abnormal abdominal reflex . Doctors foot grazed outer circumferential force , leads to an abnormal reflection , known as " Babinski reflex ." These are important to determine the diagnosis of multiple sclerosis considerations .Muscle strength ( strength ) checkMuscle strength and muscle interaction checking important step motor .Sensory testing is to assess the main touch, pain, temperature sensation , swing and positioning sleep.Autonomic nervous system automatically adjusts the respiratory and digestive functions.Your doctor can thoroughly examine the bladder, intestinal function , respiratory and circulatory systems to detect autonomic nervous system .
 
In the diagnosis of multiple sclerosis , perception, orientation , concentration , attention and emotional identification integrally psychology is also very popular means of checking .Diagnosis of MS techniques
 
Some can be used for the diagnosis of multiple sclerosis laboratory methodsNuclear magnetic resonance (MRI) imaging scansFavorite neurologist to diagnose multiple sclerosis using MRI , MRI is the ( nuclear ) magnetic resonance acronym in English .MRI is a painless screening tool, brain imaging can clearly see the white spots on the brain ( injury ) , these are precisely the characteristics of multiple sclerosis .
 
Others are used to exact diagnosis of multiple sclerosis is an electrophysiological examination . Medically known as " evoked potentials ."There are many types of evoked potentials , all of these checks to test a part or several parts of the body reaction .
 
Evoked potentials , including :l vision : visual evoked potentials or "VER"l Hearing : hearing or auditory brainstem evoked potentials or "AEBR"l cognitive function : somatosensory induced reaction or "SSER" andNuclear magnetic resonance (MRI) imagingMagnetic Resonance Imaging (MRI) is also known as magnetic resonance tomography , can provide high -resolution images of the human body imaging . The following are explanations brainstem , periventricular typical of MS on MRI imaging features
 
MRI has a superior ability to distinguish soft tissues , such as brain and spinal cord on a clear identification. MRI does not use X- rays, is in a strong magnetic field in the distinguished organizations . Distinguish the image data to be entered into the computer , and then converted to images. This method can be observed in parts of the central nervous system plaques , plaque and display position and size.Nuclear Magnetic Resonance (MRI) scans are what ?Nuclear Magnetic Resonance (MRI) scan , patients were asked to lie on a special bed, then , this bed into a narrow examination channel, this channel is actually a huge magnetic field . Inspection process, although the machine will emit some noise , and asked to be checked by lying does not move more than a half hour , but the whole process is painless . Inspection process , the operator could be checked , and the microphone and headphone communication. If that is checked for fear of confined space , you can take anti-anxiety medication in advance .
 
AngiographyThis method can be found in the new , active infection sclerosis lesions and obsolete sclerosis lesions. In the intravenous injection of contrast agents, such as gadolinium , identification of new and old lesions can seem easier.
 
Late in the disease , the extent of nerve fiber damage increasing , this time, the brain and spinal cord begins to shrink , magnetic resonance (MRI) can also be observedTo the case of brain atrophy . By MRI examination revealed brain atrophy early in the disease has occurred.
MRI usually, but not always able to find and hardening of the corresponding clinical lesions. In turn, the disease process can be found in the MRI examination also showed no clinically symptomatic sclerosis lesions, namely, " occult pathology ." Conversely , the obvious lesions on MRI , it is impossible without their corresponding clinical symptoms .
 
The sensitivity of MRI examination revealed lesions tend to be higher than the clinical observation , the former is the latter 10 times .Head and spinal cord can not be simultaneously scanned at the same time , it is necessary to determine in advance the most important part of the scan .Because the magnetic field causes the metal object can not be brought into the examination room or tomography machine. These include metal implants , such as: artificial hip joints, heart pacemakers, metal clip postoperative .
 
Two different forms of magnetic resonance (MRI) scansTwo basic forms of magnetic resonance (MRI) scansn T1 -weighted scans : You can display the new active lesions and infections locationn T2 -weighted scans : both can display active lesions , lesions and can also display still the total volume of the lesion , also known as " damage load ." T2-weighted scans can display the result of the involvement of multiple sclerosis and brain tissue volume . Ideally, the application of common T1 and T2-weighted scans can more fully understand the changes in the disease .MRI examination is only a means of multiple sclerosisDefinitive diagnosis of multiple sclerosis MRI is the most important means of laboratory tests . Meanwhile , MRI provides a neurologist early and accurate diagnosis of MS means , however, is impossible and can not rely solely on MRI in the diagnosis of multiple sclerosis .Other diseases can also cause on MRI changes in the central nervous system , multiple sclerosis, and these changes and the performance is very consistent with the MRI .Assess the progress of multiple sclerosisIn addition to helping diagnose MS, MRI in assessing the progress of MS also has great value. MRI lesion was found in the number and scope of disease activity are closely related. In addition to clinical observation, repeated MRI examination can be long-term tracking the disease process , to help doctors decide on the best and most appropriate treatment.Computed tomography (CT)Computed tomography (CT) scan of the brain specialized X-ray scan. Once the computer image processing technology, normal brain tissue and brain any changes can be observed . Radioactive and other X-ray examinations such as chest X- checking almost unanimously . For doctors, computerized tomography (CT) is not on the exclusion of other diseases and symptoms of MS and MS are similar, but not the MS disease is very useful.Evoked potentialsEvoked response ( human impact on the external stimuli ) can reflect the impaired nerve conduction information in the nervous system that occur during delays and interruptions . Myelin provides a nerve fiber insulation function and nerve conduction jump physiological basis , in multiple sclerosis , the myelin damage can cause nerve impulse conduction block.The following lists some typical evoked response test, these tests are placed around the head of the local magnetic field coil manufacturing inspection .Evoked response to help diagnose and assess the progress of multiple sclerosisEvoked response ( evoked potentials ) does not occur independently , but in the external stimulation occurs .Evoked response in the diagnosis and assessment of the progress of multiple sclerosis has an important clinical significance. When the disease has not caused significant changes in symptoms and functional impairment , the evoked potentials may have discovered the disease changes. Even in remission , or occurred years before the symptoms can also be evoked potential examination revealed pathological changes in neural pathways .
 
Can be detected in the skin to the nerve and muscle cells produced by electrophysiological responses ( potential) is not the same , for example: electrocardiography nystagmus , brain cells that produce the electrical activity can be recorded diagnostic method .
 
Evoked potential difference between various points are as follows :
 
Visual evoked potentials (VER / VEP) testing via the optic nerve pathway nerve impulse conduction. Each electrode tab pass brain stimulation for the visual response . Healthy Eyes 100-120 ms after stimulation which produce reactions. If this delayed reaction , it indicates the possibility of the existence of multiple sclerosis .Auditory evoked potentials or listen (AER / AEP) helps neurologists found to have hearing or feeling on the auditory nerve pathway disorders, as well as the cerebellum and the path to the heart of the disorder .A ticking sound through headphones communicated to the ears of those tested in the occipital region corresponding potential can be measured . This approach has been clinically determined for previously no brain dysfunction is particularly important for patients .Somatosensory evoked potentials (SSER / SSEP) through specific parts of the body , most cases are the hands and feet touch detection, including those tactile impulses to the brain condition is detected. Often with a mild electrical impulses to stimulate the tibial nerve at the ankle on the path or the median nerve or ulnar nerve pathways on the inside of the wrist to check the corresponding area of ​​the brain .Magnetic evoked potentials different from the previously discussed several evoked potential screening method.Superficial electrodes used to evaluate the upper arm and leg muscles react in different parts of the brain corresponding to the arm and leg muscle function . Brain and muscle cells are stimulated to react with a time difference between , the measured time difference can be obtained. Stimulation or spinal cord can also be located in the region to distinguish impulse conduction through the brain or spinal cord .Lumbar punctureIn order to obtain cerebrospinal fluid, doctors often perform a lumbar puncture .Although puncture technique has very advanced , but , lumbar puncture often makes people feel fear, in fact , the idea is biased .As shown in the figure , the puncture process is very short.Under local anesthesia , the iliac spine height , with a hollow needle between the spinal vertebrae protruding portion ( through the intervertebral space ) into the needle, into the central canal . Needle at least 6-10 cm , to avoid damage to the spinal cord .If the brain and spinal cord are infected , then CSF biochemical changes occur . In the laboratory testing of cerebrospinal fluid composition and compared to standard values. Help doctors determine whether the central nervous system disorders of the immune response occurs . Cerebrospinal fluid of patients with multiple sclerosis will increase the number of infected cells .Blood testsRoutine blood tests , such as blood count, liver and kidney function tests for the diagnosis of multiple sclerosis is not meaningful . The detection value of multiple sclerosis patients are often in the normal range . However, the specificity of the immune system of the blood test is valuable . These checks are used to identify and symptoms similar to the symptoms of multiple sclerosis and other diseases , such as infectious diseases or immune system disorders diseases. Among them, a human leukocyte antigen detecting leukocytes method can sometimes provide the basis for diagnosis of multiple sclerosis .Other testsEye movement examinationAnother laboratory technique , known as " nystagmus electric plethysmography ," also known as " ENG ."Multiple sclerosis patients , because the brain stem and cerebellum demyelination , normal eye movements can lead to damage . Therefore, the stimulation of abnormal visual response can make the neurologist found visual problems .Blink reflex examinationBlink reflex examination can reflect the brainstem neuronal damage. Stem cells in multiple sclerosis patients are often involved. In the eyelid counter electrode , the eyebrows given with electric pulses , reflections can be induced and measured , too. Typical symptoms of multiple sclerosis patients is absent blink reaction or the reaction delay .
