Management Corticosteroids may be effective in some patients. Additional treatment options are beta-interferon or immunosuppressive therapy. Otherwise management is supportive and includes physiotherapy, occupational therapy and nutritional support in the later stages as patients lose their ability to eat.
The prognosis of this disease is very variable and can take three different courses: a monophasic, not remitting;
remitting;
and finally, progressive, with increase in deficits.
The disease-modifying treatments have several adverse effects. One of the most common is irritation at the injection site for glatiramer acetate and the interferons (up to 90% with subcutaneous injections and 33% with intramuscular injections). Over time, a visible dent at the injection site, due to the local destruction of fat tissue, known as lipoatrophy, may develop. Interferons may produce flu-like symptoms; some people taking glatiramer experience a post-injection reaction with flushing, chest tightness, heart palpitations, and anxiety, which usually lasts less than thirty minutes. More dangerous but much less common are liver damage from interferons, systolic dysfunction (12%), infertility, and acute myeloid leukemia (0.8%) from mitoxantrone, and progressive multifocal leukoencephalopathy occurring with natalizumab (occurring in 1 in 600 people treated).
Fingolimod may give rise to hypertension and slowed heart rate, macular edema, elevated liver enzymes or a reduction in lymphocyte levels. Tentative evidence supports the short-term safety of teriflunomide, with common side effects including: headaches, fatigue, nausea, hair loss, and limb pain. There have also been reports of liver failure and PML with its use and it is dangerous for fetal development. Most common side effects of dimethyl fumarate are flushing and gastrointestinal problems. While dimethyl fumarate may lead to a reduction in the white blood cell count there were no reported cases of opportunistic infections during trials.
Pharmacologic treatments for MS include immunomodulators and immunosuppressants which reduce the frequency and severity of relapses by about 35% and reduce the lesion growth. Unfortunately they are mainly tested for RRMS and its effect in tumefactive lesions is unknown. The main ones are Interferon beta (IFN-beta), Glatiramer acetate and Mitoxantrone
Plasma exchange has been reported to work at least in some cases
Both medications and neurorehabilitation have been shown to improve some symptoms, though neither changes the course of the disease. Some symptoms have a good response to medication, such as an unstable bladder and spasticity, while others are little changed. For neurologic problems, a multidisciplinary approach is important for improving quality of life; however, it is difficult to specify a 'core team' as many health services may be needed at different points in time. Multidisciplinary rehabilitation programs increase activity and participation of people with MS but do not influence impairment level. There is limited evidence for the overall efficacy of individual therapeutic disciplines, though there is good evidence that specific approaches, such as exercise, and psychology therapies, in particular cognitive behavioral approaches are effective.
There are no approved drugs for the treatment of cognitive dysfunction, however, some treatments have shown an association with improvements in cognitive function. One such treatment is "Ginkgo biloba", is a herb commonly used by patients with Alzheimer's disease.
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) because the unknown etiology of some of them, and sometimes known as borderline forms of multiple sclerosis, is a collection of multiple sclerosis variants, sometimes considered different diseases, but considered by others to form a spectrum differing only in terms of chronicity, severity, and clinical course.
Multiple Sclerosis for some people is a syndrome more than a single disease. It can be considered among the acquired demyelinating syndromes with a multiphasic instead of monophasic behaviour. Multiple sclerosis also has a prodromal stage in which an unknown underlying condition, able to damage the brain, is present, but no lesion has still developed.
Treatment typically involves improving the patient's quality of life. This is accomplished through the management of symptoms or slowing the rate of demyelination. Treatment can include medication, lifestyle changes (i.e. quit smoking, adjusting daily schedules to include rest periods and dietary changes), counselling, relaxation, physical exercise, patient education and, in some cases, deep brain thalamic stimulation (in the case of tremors). The progressive phase of MS appears driven by the innate immune system, which will directly contribute to the neurodegenerative changes that occur in progressive MS. Until now, there are no therapies that specifically target innate immune cells in MS. As the role of innate immunity in MS becomes better defined, it may be possible to better treat MS by targeting the innate immune system.
Treatments are patient-specific and depend on the symptoms that present with the disorder, as well as the progression of the condition.
An average clinical profile from published studies shows that the median onset age for HDLS patients is 44.3 years with a mean disease duration of 5.8 years and mean age of death at 53.2 years. As of 2012, there have been around 15 cases identified with at least 11 sporadic cases of HDLS. HDLS cases have been located in Germany, Norway, Sweden, and the United States, showing an international distribution focusing between Northern Europe and the United States.
Through the study of numerous kindred, it was found that the disease did not occur among just males or females, but rather was evenly distributed indicative of an autosomal rather than a sex-linked genetic disorder. It was also observed that the HDLS cases did not skip generations as it would occur with a recessive inheritance, and as such has been labeled autosomal dominant.
Experimentation has shown that manipulating the levels of thyroid hormone can be considered as a strategy to promote remyelination and prevent irreversible damage in Multiple sclerosis patients. N-cadherin agonists have been identified and observed to stimulate neurite growth and cell migration, key aspects of promoting axon growth and remyelination after injury or disease. It has been shown that intranasal administration of aTf (apotransferrin) can protect myelin and induce remyelination.
Much of the research referenced in this section has been conducted in 2012 and represents very new information about demyelinating diseases and potential therapies for them.
A clinically isolated syndrome (CIS) is a clinical situation of an individual's first neurological episode, caused by inflammation or demyelination of nerve tissue. An episode may be monofocal, in which symptoms present at a single site in the central nervous system, or multifocal, in which multiple sites exhibit symptoms. CIS with enough paraclinical evidence can be considered as a clinical stage of Multiple Sclerosis (MS). It can also be retrospectively diagnosed as a kind of MS when more evidence is available.
Brain lesions associated with a clinically isolated syndrome may be indicative of several neurological diseases, like multiple sclerosis (MS) or Neuromyelitis optica. In order for such a diagnosis, multiple sites in the central nervous system must present lesions, typically over multiple episodes, and for which no other diagnosis is likely. A clinically definitive diagnosis of MS is made once an MRI detects lesions in the brain, consistent with those typical of MS. Other diagnostics include cerebrospinal fluid analysis and evoked response testing.
Currently it is considered that the best predictor of future development of clinical multiple sclerosis is the number of T2 lesions visualized by magnetic resonance imaging during the CIS. It is normal to evaluate diagnostic criteria against the "time to conversion to definite".
In 2001, the International Panel on the Diagnosis of Multiple Sclerosis issued the McDonald criteria, a revision of the previous diagnostic procedures to detect MS, known as the Poser criteria. "While maintaining the basic requirements of dissemination in time and space, the McDonald criteria provided specific guidelines for using findings on MRI and cerebrospinal fluid analysis to provide evidence of the second attack in those individuals who have had a single demyelinating episode and thereby confirm the diagnosis more quickly." Further revisions were issued in 2005.
Around 95% of MS cases present oligoclonal bands in CSF. Nevertheless, there are cases of real MS that do not have them. It is suspected to be immunogenetically different. Their evolution is better than standard MS patients
Balo concentric sclerosis is a disease in which the white matter of the brain appears damaged in concentric layers, leaving the axis cylinder intact. It was described by Joszef Balo who initially named it "leuko-encephalitis periaxialis concentrica" from the previous definition, and it is currently considered one of the borderline forms of multiple sclerosis.
Balo concentric sclerosis is a demyelinating disease similar to standard multiple sclerosis, but with the particularity that the demyelinated tissues form concentric layers. Scientists used to believe that the prognosis was similar to Marburg multiple sclerosis, but now they know that patients can survive, or even have spontaneous remission and asymptomatic cases.
It is also common that the clinical course is primary progressive, but a relapsing-remitting course has been reported.
It seems that the course gets better with prednisone therapy, although evidence of this is anecdotal and such conclusions are difficult to accept given that there are cases where patients spontaneously recover whether the patient was on steroid therapy or not.
Marburg acute multiple sclerosis, also known as Marburg multiple sclerosis or acute fulminant multiple sclerosis, is considered one of the multiple sclerosis borderline diseases, which is a collection of diseases classified by some as MS variants and by others as different diseases. Other diseases in this group are neuromyelitis optica (NMO), Balo concentric sclerosis, and Schilder's disease. The graver course is one form of malignant multiple sclerosis, with patients reaching a significant level of disability in less than five years from their first symptoms, often in a matter of months.
Sometimes Marburg MS is considered a synonym for tumefactive MS, but not for all authors.
The disease is more common in Chinese and Filipino populations (both Asiatic) than in caucasoids.
Marburg variant of MS is an acute fulminant demyelinating process which in most cases progresses inexorably to death within 1–2 years. However, there are some reports of Marburg MS reaching stability by three years.
Hereditary diffuse leukoencephalopathy with spheroids (HDLS) is a rare adult onset autosomal dominant disorder characterized by cerebral white matter degeneration with demyelination and axonal spheroids leading to progressive cognitive and motor dysfunction. Spheroids are axonal swellings with discontinuous or absence of myelin sheaths. It is believed that the disease arises from primary microglial dysfunction that leads to secondary disruption of axonal integrity, neuroaxonal damage, and focal axonal spheroids leading to demyelination. Spheroids in HDLS resemble to some extent those produced by shear stress in a closed head injury with damage to axons, causing them to swell due to blockage of axoplasmic transport. In addition to trauma, axonal spheroids can be found in aged brain, stroke, and in other degenerative diseases. In HDLS, it is uncertain whether demyelination occurs prior to the axonal spheroids or what triggers neurodegeneration after apparently normal brain and white matter development, although genetic deficits suggest that demyelination and axonal pathology may be secondary to microglial dysfunction. The clinical syndrome in patients with HDLS is not specific and it can be mistaken for Alzheimer's disease, frontotemporal dementia, atypical Parkinsonism, multiple sclerosis, or corticobasal degeneration.
Treatment of ALS2-related disorders includes physical therapy and occupational therapy to promote mobility and independence and use of computer technologies and devices to facilitate writing and voice communication.
In terms of treatment for neuromuscular diseases (NMD), "exercise" might be a way of managing them, as NMD individuals would gain muscle strength. In a study aimed at results of exercise, in muscular dystrophy and Charcot-Marie-Tooth disease, the later benefited while the former did not show benefit; therefore, it depends on the disease Other management routes for NMD should be based on medicinal and surgical procedures, again depending on the underlying cause.
The 1996 definition of the clinical courses of MS (phenotypes) was updated on 2013 by an international panel (International Advisory Committee on Clinical Trials).
While the main classification in 1996 was the recovery from the attacks (this clinical feature separates RR from progressive), in the updated revision the main classification is the activity.
MS courses in the new revision are divided into active and non-active, and CIS, when is active on MRI, becomes a kind of RRMS (this, of course, must be retrospectively diagnosed after the CDMS conversion)
Some reviews describe CIS as "the prodromal stage of MS".
Socioeconomic correlates of health have been well established in the study of heart disease, lung cancer, and diabetes. Many of the explanations for the increased incidence of these conditions in people with lower socioeconomic status (SES) suggest they are the result of poor diet, low levels of exercise, dangerous jobs (exposure to toxins etc.) and increased levels of smoking and alcohol intake in socially deprived populations. Hesdorffer et al. found that low SES, indexed by poor education and lack of home ownership, was a risk factor for epilepsy in adults, but not in children in a population study. Low socioeconomic status may have a cumulative effect for the risk of developing epilepsy over a lifetime.
There were also observations that hippocampal sclerosis was associated with vascular risk factors. Hippocampal sclerosis cases were more likely than Alzheimer's disease to have had a history of stroke (56% vs. 25%) or hypertension (56% vs. 40%), evidence of small vessel disease (25% vs. 6%), but less likely to have had diabetes mellitus (0% vs. 22%).
Juvenile primary lateral sclerosis (JPLS) ", also known as primary lateral sclerois (PLSJ)," is a rare genetic disorder, with a small number of reported cases, characterized by progressive weakness and stiffness of muscles in the arms, legs, and face. The disorder damages motor neurons, which are specialized nerve cells in the brain and spinal cord that control muscle movement.
CNS demyelinating autoimmune diseases are autoimmune diseases which primarily affect the central nervous system.
Examples include:
- Diffuse cerebral sclerosis of Schilder
- Acute disseminated encephalomyelitis
- Acute hemorrhagic leukoencephalitis
- Multiple sclerosis (though the cause is unknown, it is sure that immune system is involved)
- Transverse myelitis
- Neuromyelitis optica
Research is also under way to evaluate the effect and safety of plasmablast-directed therapy with a monoclonal antibody (XmAb5871) which inhibits B-cell function without depleting these immune cells. XmAb5871 targets CD19 with its variable domain and has an Fc domain that has increased affinity to FcγRIIb.
