Multiple sclerosis (MS) is an autoimmune disease of unknown cause that affects the central nervous system. While most of them are still under research, there are some of them already well stablished: Several conditions can mimic MS. Studies of American MS patients have shown that people with MS also tend to exhibit these HLAs in combination—that is, they have more than one of the three HLAs—more frequently than the rest of the population. In CIS, a person has an attack suggestive of demyelination, but does not fulfill the criteria for multiple sclerosis. Lancet Neurol 2011; 10: 436–445. Because MRI can reveal lesions which occurred previously but produced no clinical symptoms, it can provide the evidence of chronicity needed for a definite diagnosis of MS. Alternatively, a benzodiazepine, diazepam, may be used instead of or in synergy with baclofen. It is equally important to elicit the onset, duration and temporal relationship of symptoms. Currently, however, there are no approved treatments for primary progressive multiple sclerosis, though several medications are being studied. J Neuroimmunol. The chronic inflammation, degeneration and demyelination of axons in the CNS lead to the clinical presentation of neurologic dysfunction. There is debate on whether they are MS variants or different diseases.

Here a table is shown with each one of them: If none of these requirements is fulfilled, the diagnosis is "No MS", meaning that there is not enough clinical evidence to support a clinical diagnosis of MS. Barkhof criteria,[13] later modified by Tintoré[14] were an early attempt to use MRI to diagnose MS. Their observations were taken into account when McDonald criteria were published, and therefore they can be considered deprecated by the latter. Optic Neuritis Study Group. For musculoskeletal spasticity, the GABA agonist baclofen is usually the first choice. Anyhow, the fact that the rate for identical twins both developing MS is significantly less than 100% suggests that the disease is not entirely genetically controlled. [20], Unusual types of MS have been described; these include Devic's disease, Balo concentric sclerosis, Schilder's diffuse sclerosis, and Marburg multiple sclerosis.

[30] Other FDA-approved disease-modifying drugs include fingolimod, teriflunomide, dimethyl fumarate, natalizumab, alemtuzumab, ocrelizumab and siponimod. Diagnostic criteria for multiple sclerosis: 2010 Revisions to the McDonald criteria. MS is classically described as a condition in which neurologic symptoms vary in time and space.

Beck RW, Cleary PA, Backlund JC. Treatment is aimed at returning function after an attack, preventing new attacks, and preventing disability. On a molecular level, this might occur if there is a structural similarity between the infectious virus and some component of the central nervous system, leading to eventual confusion in the immune system. Other theories describe MS as an immune response to a chronic infection, as with viral infections described above, but that the infection remains and has a more direct effect on the development of MS. [3] The myelin is like the insulator around the wire that keeps the signal strong by keeping it from moving out of the wire before the end. 2005 May. Examination showed temporal pallor of both optic discs. Changes in sensation can present as pain, numbness, tingling, or pins and needles sensation. However, corticosteroids have not been shown to improve final visual outcomes. These leaks, in turn, cause a number of other damaging effects such as swelling, activation of macrophages, and more activation of cytokines and other destructive proteins such as matrix metalloproteinases. Some previous cases considered MS are now considered apart, like Neuromyelitis optica or antiMOG associated encephalomyelitis. People with MS can participate in sports, but they should probably avoid extremely strenuous exertion, such as marathon running. [21], Multiple sclerosis relapses are often unpredictable and can occur without warning with no obvious inciting factors. Bashinskaya VV, Kulakova OG, Boyko AN, Favorov AV, Favorova OO. The error can be important in some areas, and is considered to be 30% in Japan. Scientists have not yet found a way to cure MS, or take it away entirely.

Rae-Grant A, Fox R, Bethoux F. Multiple Sclerosis and Related Disorders: Diagnosis, Medical Management, and Rehabilitation. A healthy neuron with myelin sheath around the long, thin axon. It is characterized by focal demyelinating lesions in the white matter of the brain or spinal cord that vary temporally and spatially, thereby leading to the classic presentation of episodic neurologic symptoms. Other regions on chromosomes 2, 3, 7, 11, 17, 19, and X have also been identified as possibly containing genes involved in the development of MS. This page was last modified on June 22, 2020, at 14:20.

Magnetic resonance imaging showed enhancement of the retrobulbar optic nerve and multiple demyelinating lesions. Some scientists think that a relatively unknown pathogen called Chlamydia pneumoniae may cause MS.[8][9] Also, some viruses can cause myelin damage, there are other viruses that have been shown to make people more likely to get MS.[1][8][10] Even though scientists and doctors have theories, no one has found one cause that explains every case of the disease. [26], Pregnancy can directly affect the susceptibility for relapse. [18] This condition presents with diplopia, nystagmus, and loss of depth perception (stereopsis) secondary to an adduction deficit or adduction lag on conjugate gaze. The immune system attacks either the fatty parts of the myelin or the protein parts of the myelin. It is characterized by focal demyelinating lesions in the white matter of the brain or spinal cord that vary temporally and spatially, thereby leading to the classic presentation of episodic neurologic symptoms. When deficits always resolve between attacks, this is referred to as "benign" MS. Primary progressive describes the approximately 10% of individuals who never have remission after their initial MS symptoms. It should be noted that most of these outcomes were observed before the use of medications such as interferon, which can delay disease progression for several years. [26], The primary progressive subtype occurs in approximately 10–20% of individuals, with no remission after the initial symptoms. There are many supportive treatments, although only dalfampridine has a specific FDA approval for use in MS, to help decreased walking speed. Long-term disability progression in primary progressive multiple sclerosis: a 15-year study. [2] In those who seek medical attention after only one attack, other testing is needed for the diagnosis. The exam consists of the evaluation of cranial nerves, deep tendon reflexes, motor strength, sensation, gait, balance and coordination. BMC Neurol. multiple-sclerosis-pro: MeSH: D009103: Information med symbolet hentes fra Wikidata.

The morbidity of multiple sclerosis. Costello F. Inflammatory optic neuropathies. Internuclear ophthalmoplegia occurs in about 30% of patients. 2010 Dec 15;229(1-2):5-15. Summarizing previous reports and adding his own important clinical and pathological observations, Charcot called the disease sclerose en plaques. Eye movement abnormalities in multiple sclerosis. The McDonald Criteria should be met in order to diagnose multiple sclerosis. The tricyclic antidepressant amitriptyline may help both depression and chronic pain. More treatments are being studied and undergoing the approval process. It is also a requirement that any possible known disease that produces demyelinating lesions is ruled out before applying McDonald's criteria. [1] A doctor can also order tests to be done by a laboratory, which can determine how active the immune system is in the patient. Weighted bracelets or even a weighted vest may be useful. Dissemination in time, demonstrated by an additional clinical attack or by MRI. Contents.

Family history of MS is also relevant as there is a genetic predisposition to the disease. Willer CJ, Dyment DA, Risch NJ, Sadovnick AD, Ebers GC; Twin concordance and sibling recurrence rates in multiple sclerosis. Furthermore, a deficiency of uric acid has been implicated in the immunological development of MS[42]. The primary progressive subtype tends to affect people who are older at disease onset. Secondary progressive describes around 80% of those with initial relapsing-remitting MS, who then begin to have neurologic decline between their acute attacks without any definite periods of remission. Up to 30% of patients eventually require assistance for ambulation, and 22% become wheelchair bound. Berger T, Rubner P, Schautzer F, Egg R, Ulmer H, Mayringer I, Dilitz E, Deisenhammer F, Reindl M. Pittock SJ; McClelland RL; Mayr WT; Jorgensen NW; Weinshenker BG; Noseworthy J; Rodriguez M. Sadovnick, AD, Ebers, GC, Dyment, DA, Risch, NJ. [5], Progressive relapsing MS describes those individuals who, from onset, have a steady neurologic decline but also have clear superimposed attacks.
