Multiple sclerosis Wikipedia. Multiple sclerosis MS is a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. This damage disrupts the ability of parts of the nervous system to communicate, resulting in a range of signs and symptoms, including physical, mental, and sometimes psychiatric problems. Specific symptoms can include double vision, blindness in one eye, muscle weakness, trouble with sensation, or trouble with coordination. MS takes several forms, with new symptoms either occurring in isolated attacks relapsing forms or building up over time progressive forms. Between attacks, symptoms may disappear completely however, permanent neurological problems often remain, especially as the disease advances. While the cause is not clear, the underlying mechanism is thought to be either destruction by the immune system or failure of the myelin producing cells. Proposed causes for this include genetics and environmental factors such as being triggered by a viral infection. MS is usually diagnosed based on the presenting signs and symptoms and the results of supporting medical tests. There is no known cure for multiple sclerosis. Treatments attempt to improve function after an attack and prevent new attacks. Medications used to treat MS, while modestly effective, can have side effects and be poorly tolerated. Physical therapy can help with peoples ability to function. Many people pursue alternative treatments, despite a lack of evidence. The long term outcome is difficult to predict, with good outcomes more often seen in women, those who develop the disease early in life, those with a relapsing course, and those who initially experienced few attacks.

The name multiple sclerosis refers to the numerous scars scleraebetter known as plaques or lesions that develop on the white matter of the brain and spinal cord. A number of new treatments and diagnostic methods are under development. Signs and symptoms. Main symptoms of multiple sclerosis. A person with MS can have almost any neurological symptom or sign, with autonomic, visual, motor, and sensory problems being the most common. The specific symptoms are determined by the locations of the lesions within the nervous system, and may include loss of sensitivity or changes in sensation such as tingling, pins and needles or numbness, muscle weakness, blurred vision,1. Poser - Sa Phenotypes' title='Poser - Sa Phenotypes' />Difficulties thinking and emotional problems such as depression or unstable mood are also common. Uhthoffs phenomenon, a worsening of symptoms due to exposure to higher than usual temperatures, and Lhermittes sign, an electrical sensation that runs down the back when bending the neck, are particularly characteristic of MS. The main measure of disability and severity is the expanded disability status scale EDSS, with other measures such as the multiple sclerosis functional composite being increasingly used in research. The condition begins in 8. CIS over a number of days with 4. The course of symptoms occurs in two main patterns initially either as episodes of sudden worsening that last a few days to months called relapses, exacerbations, bouts, attacks, or flare ups followed by improvement 8. A combination of these two patterns may also occur1. Relapses are usually not predictable, occurring without warning. Exacerbations rarely occur more frequently than twice per year. Some relapses, however, are preceded by common triggers and they occur more frequently during spring and summer. Similarly, viral infections such as the common cold, influenza, or gastroenteritis increase their risk. Stress may also trigger an attack. Women with MS who become pregnant experience fewer relapses however, during the first months after delivery the risk increases. Overall, pregnancy does not seem to influence long term disability. Many events have been found not to affect relapse rates including vaccination, breast feeding,5 physical trauma,2. C Start Stop Windows Service Remotely Enable Remote there. Uhthoffs phenomenon. Causes. The cause of MS is unknown however, it is believed to occur as a result of some combination of genetic and environmental factors such as infectious agents. Theories try to combine the data into likely explanations, but none has proved definitive. While there are a number of environmental risk factors and although some are partly modifiable, further research is needed to determine whether their elimination can prevent MS.

MS is more common in people who live farther from the equator, although exceptions exist. These exceptions include ethnic groups that are at low risk far from the equator such as the Samis, Amerindians, Canadian Hutterites, New Zealand Mori,2. Canadas Inuit,2 as well as groups that have a relatively high risk close to the equator such as Sardinians,2 inland Sicilians,2. Palestinians and Parsis. The cause of this geographical pattern is not clear. While the north south gradient of incidence is decreasing,2. MS is more common in regions with northern European populations5 and the geographic variation may simply reflect the global distribution of these high risk populations. Decreased sunlight exposure resulting in decreased vitamin D production has also been put forward as an explanation. Ce dossier, non finalis, est en construction. Contact auteur eric. Le Morvan est un territoire formidable parfois saccag, pollu par. A relationship between season of birth and MS lends support to this idea, with fewer people born in the northern hemisphere in November as compared to May being affected later in life. Environmental factors may play a role during childhood, with several studies finding that people who move to a different region of the world before the age of 1. MS. If migration takes place after age 1. There is some evidence that the effect of moving may still apply to people older than 1. Genetics. HLA region of Chromosome 6. Changes in this area increase the probability of getting MS. MS is not considered a hereditary disease however, a number of genetic variations have been shown to increase the risk. Some of these genes appear to have higher levels of expression in microglial cells than expected by chance. The probability of developing the disease is higher in relatives of an affected person, with a greater risk among those more closely related. In identical twins both are affected about 3. If both parents are affected the risk in their children is 1. MS is also more common in some ethnic groups than others. Specific genes that have been linked with MS include differences in the human leukocyte antigen HLA systema group of genes on chromosome. MHC. 5 That changes in the HLA region are related to susceptibility has been known since the 1. I and systemic lupus erythematosus. The most consistent finding is the association between multiple sclerosis and alleles of the MHC defined as DR1. DQ6. 5 Other loci have shown a protective effect, such as HLA C5. HLA DRB11. 1. 5 Overall, it has been estimated that HLA changes account for between 2. Modern genetic methods genome wide association studies have discovered at least twelve other genes outside the HLA locus that modestly increase the probability of MS. Infectious agents.
