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.

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.

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

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.

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.

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.

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

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.

Currently, there is no cure for Devic's disease, but symptoms can be treated. Some patients recover, but many are left with impairment of vision and limbs, which can be severe.

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.

No controlled trials have established the effectiveness of treatments for the prevention of attacks. Many clinicians agree that long term immunosuppression is required to reduce the frequency and severity of attacks, while others argue the exact opposite. Commonly used immunosuppressant treatments include azathioprine (Imuran) plus prednisone, mycophenolate mofetil plus prednisone, mitoxantrone, intravenous immunoglobulin (IVIG), and cyclophosphamide.

Though the disease is known to be auto-antibodies mediated, B-cell depletion has been tried with the monoclonal antibody rituximab, showing good results.

Several other disease modifying therapies are being tried. In 2007, Devic's disease was reported to be responsive to glatiramer acetate and to low-dose corticosteroids. Use of Mycophenolate mofetil is also currently under research.

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.

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.

Balo lesions have been reported alone, but also associated to standard multiple sclerosis, neuromyelitis optica, CADASIL and progressive multifocal leukoencephalopathy

In the US, neuroborreliosis is typically treated with intravenous antibiotics which cross the blood–brain barrier, such as penicillins, ceftriaxone, or cefotaxime. One relatively small randomized controlled trial suggested ceftriaxone was more effective than penicillin in the treatment of neuroborreliosis. Small observational studies suggest ceftriaxone is also effective in children. The recommended duration of treatment is 14 to 28 days.

Several studies from Europe have suggested oral doxycycline is equally as effective as intravenous ceftriaxone in treating neuroborreliosis. Doxycycline has not been widely studied as a treatment in the US, but antibiotic sensitivities of prevailing European and US isolates of "Borrelia burgdorferi" tend to be identical. However, doxycycline is generally not prescribed to children due to the risk of bone and tooth damage.

Discreditied or doubtful treatments for neuroborreliosis include:

- Malariotherapy

- Hyperbaric oxygen therapy

- Colloidal silver

- Injections of hydrogen peroxide and bismacine

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".

Given that some conditions as MS show cortical damage together with the WM damage, there has been interest if this can appear as a secondary damage of the WM. It seems that some researchers claim so.

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

Neurosarcoidosis, once confirmed, is generally treated with glucocorticoids such as prednisolone. If this is effective, the dose may gradually be reduced (although many patients need to remain on steroids long-term, frequently leading to side-effects such as diabetes or osteoporosis). Methotrexate, hydroxychloroquine, cyclophosphamide, pentoxifylline, thalidomide and infliximab have been reported to be effective in small studies. In patients unresponsive to medical treatment, radiotherapy may be required. If the granulomatous tissue causes obstruction or mass effect, neurosurgical intervention is sometimes necessary. Seizures can be prevented with anticonvulsants, and psychiatric phenomena may be treated with medication usually employed in these situations.

Since each case is different, the following are possible treatments that patients might receive in the management of myelitis.

- Intravenous steroids

High-dose intravenous methyl-prednisolone for 3–5 days is considered as a standard of care for patients suspected to have acute myelitis, unless there are compelling reasons otherwise. The decision to offer continued steroids or add a new treatment is often based on the clinical course and MRI appearance at the end of 5 days of steroids.

- Plasma exchange (PLEX)

Patients with moderate to aggressive forms of disease who don’t show much improvement after being treated with intravenous and oral steroids will be treated with PLEX. Retrospective studies of patients with TM treated with IV steroids followed by PLEX showed a positive outcome. It also has been shown to be effective with other autoimmune or inflammatory central nervous system disorders. Particular benefit has been shown with patients who are in the acute or subacute stage of the myelitis showing active inflammation on MRI. However, because of the risks implied by the lumbar puncture procedure, this intervention is determined by the treating physician on a case-by-case basis.

- Immunosuppressants/Immunomodulatory agents

Myelitis with no definite cause seldom recurs, but for others, myelitis may be a manifestation of other diseases that are mentioned above. In these cases, ongoing treatment with medications that modulate or suppress the immune system may be necessary. Sometimes there is no specific treatment. Either way, aggressive rehabilitation and long-term symptom management are an integral part of the healthcare plan.

Early and aggressive treatment is important to prevent irreversible neurological damage, hearing loss, or vision loss. Medications used include immunosuppressive agents and corticosteroids such a prednisone, or intravenous immunoglobulins (IVIG). Other drugs that have been used are mycophenolate mofetil (Cellcept), azathioprine (Imuran), cyclophosphamide, rituximab, and anti-TNF therapies.

Hearing aids or cochlear implants may be necessary in the event of hearing loss.

Sometimes the human equivalent to EAE has been triggered in humans by accident or medical mistake. The reactions have been diverse according to the sources of the disease The researchers in the last report have termed the condition "Human autoimmune encephalitis" (HAE).

The damage in the second report fulfilled all pathological diagnostic criteria of MS and can therefore be classified as MS in its own right. The lesions were classified as pattern II in the Lucchinetti system. This case of human EAE also showed Dawson fingers

Using the confluent demyelination as barrier between MS and ADEM, some other reports about EAE in humans classify its effects as ADEM but not always. In Japanese patients exposed to rabies vaccine that contained neural tissue, the clinical presentation resembled ADEM more than MS but the lesions were like acute multiple sclerosis (Uchimura and Shiraki, 1957).

Recent problems with monoclonal antibodies point to an involvement of tumor necrosis factor alpha in the multiple sclerosis onset.

Of the phenomena occurring in neurosarcoid, only facial nerve involvement is known to have a good prognosis and good response to treatment. Long-term treatment is usually necessary for all other phenomena. The mortality rate is estimated at 10%

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.
