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.

Central nervous system nerve regeneration would be able to repair or regenerate the damage caused to the spinal cord. It would restore functions lost due to the disease.

- Engineering endogenous repair

Currently, there exists a hydrogel based scaffold which acts as a channel to deliver nerve growth-enhancing substrates while providing structural support. These factors would promote nerve repairs to the target area. Hydrogels' macroporous properties would enable attachment of cells and enhance ion and nutrient exchange. In addition, hydrogels' biodegradability or bioresolvability would prevent the need for surgical removal of the hydrogel after drug delivery. It means that it would be dissolved naturally by the body's enzymatic reaction.

- Biochemical repair

- Stem cell based therapies

The possibility for nerve regeneration after injury to the spinal cord was considered to be limited because of the absence of major neurogenesis. However, Joseph Altman showed that cell division does occur in the brain which allowed potential for stem cell therapy for nerve regeneration. The stem cell-based therapies are used in order to replace cells lost and injured due to inflammation, to modulate the immune system, and to enhance regeneration and remyelination of axons. Neural stem cells (NSC) have the potential to integrate with the spinal cord because in the recent past investigations have demonstrated their potential for differentiation into multiple cell types that are crucial to the spinal cord. Studies show that NSCs that were transplanted into a demyelinating spinal cord lesion were found to regenerate oligodendrocytes and Schwann cells, and completely remyelinated axons.

There is no cure for polioencephalitis so prevention is essential. Many people that become infected will not develop symptoms and their prognosis is excellent. However, the prognosis is dependent on the amount of cellular damage done by the virus and the area of the brain affected. Many people that develop more severe symptoms can have lifelong disabilities or it can lead to death. Supportive treatments include bed rest, pain relievers, and a nutritious diet. Many drugs have been used to treat psychiatric symptoms such as Clonazepam for insomnia and Desvenlafaxine or Citalopram for depressed mood.

Treatments of proven efficacy are currently limited mostly to herpes viruses and human immunodeficiency virus. The herpes virus is of two types: herpes type 1 (HSV-1, or oral herpes) and herpes type 2 (HSV-2, or genital herpes). Although there is no particular cure; there are treatments that can relieve the symptoms. Drugs like Famvir, Zovirax, and Valtrex are among the drugs used, but these medications can only decrease pain and shorten the healing time. They can also decrease the total number of outbreaks in the surrounding. Warm baths also may relive the pain of genital herpes.

Human Immunodeficiency Virus Infection (HIV) is treated by using a combination of medications to fight against the HIV infection in the body. This is called antiretroviral therapy (ART). ART is not a cure, but it can control the virus so that a person can live a longer, healthier life and reduce the risk of transmitting HIV to others around him. ART involves taking a combination of HIV medicines (called an HIV regimen) every day, exactly as prescribed by the doctor. These HIV medicines prevent HIV Virus from multiplying (making copies of itself in the body), which reduces the amount of HIV in the body. Having less HIV in the body gives the immune system a chance to recover and fight off infections and cancers. Even though there is still some HIV in the body, the immune system is strong enough to fight off infections and cancers. By reducing the amount of HIV in the body, HIV medicines also reduce the risk of transmitting the virus to others. ART is recommended for all people with HIV, regardless of how long they’ve had the virus or how healthy they are. If left untreated, HIV will attack the immune system and eventually progress to AIDS.

Development of new therapies has been hindered by the lack of appropriate animal model systems for some important viruses and also because of the difficulty in conducting human clinical trials for diseases that are rare. Nonetheless, numerous innovative approaches to antiviral therapy are available including candidate thiazolide and purazinecarboxamide derivatives with potential broad-spectrum antiviral efficacy. New herpes virus drugs include viral helicase-primase and terminase inhibitors. A promising new area of research involves therapies based on enhanced understanding of host antiviral immune responses.

Herpesviral Encephalitis can be treated with high-dose intravenous acyclovir. Without treatment, HSE results in rapid death in approximately 70% of cases; survivors suffer severe neurological damage. When treated, HSE is still fatal in one-third of cases, and causes serious long-term neurological damage in over half of survivors. Twenty percent of treated patients recover with minor damage. Only a small population of survivors (2.5%) regain completely normal brain function. Indeed, many amnesic cases in the scientific literature have etiologies involving HSE. Earlier treatment (within 48 hours of symptom onset) improves the chances of a good recovery. Rarely, treated individuals can have relapse of infection weeks to months later. There is evidence that aberrant inflammation triggered by herpes simplex can result in granulomatous inflammation in the brain, which responds to steroids. While the herpes virus can be spread, encephalitis itself is not infectious. Other viruses can cause similar symptoms of encephalitis, though usually milder (Herpesvirus 6, varicella zoster virus, Epstein-Barr, cytomegalovirus, coxsackievirus, etc.).

Lupus is a condition with no known cure. Lupus cerebritis however is treated by suppressing the autoimmune activity.

When it is caused by infections, treatment consists of medication that will primarily cure the infection. For inflammation, steroids can be used to bring down the swelling. If the swelling appears to have increased to a dangerous level, surgery may be needed to relieve pressure on the brain. The formation of an abscess also calls for surgery as it will be necessary to drain the abscess.

Ataxia usually goes away without any treatment. In cases where an underlying cause is identified, your doctor will treat the underlying cause. In extremely rare cases, you may have continuing and disabling symptoms. Treatment includes corticosteroids, Intravenous immunoglobulin, or plasma exchange therapy. Drug treatment to improve muscle coordination has a low success rate. However, the following drugs may be prescribed: clonazepam, amantadine, gabapentin, or buspirone. Occupational or physical therapy may also alleviate lack of coordination. Changes to diet and nutritional supplements may also help. Treatment will depend on the cause. If the acute cerebellar ataxia is due to bleeding, surgery may be needed. For a stroke, medication to thin the blood can be given. Infections may need to be treated with antibiotics. Steroids may be needed for swelling (inflammation) of the cerebellum (such as from multiple sclerosis). Cerebellar ataxia caused by a recent viral infection may not need treatment.

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.

Encephalomyelitis is inflammation of the brain and spinal cord. Various types of encephalomyelitis include:

- "Acute disseminated encephalomyelitis" or "postinfectious encephalomyelitis", a demyelinating disease of the brain and spinal cord, possibly triggered by viral infection.

- "Encephalomyelitis disseminata", a synonym for multiple sclerosis.

- "AntiMOG associated encephalomyelitis", one of the underlying conditions for the phenotype neuromyelitis optica and in general all the spectrum of MOG autoantibody-associated demyelinating diseases.

- "Equine encephalomyelitis", also called "equine encephalitis", a potentially fatal mosquito-borne viral disease that infects horses and humans.

- "Myalgic encephalomyelitis", a disease involving presumed inflammation of the central nervous system with symptoms of muscle pain and fatigue; the term has sometimes been used interchangeably with "chronic fatigue syndrome", though there is still controversy over the distinction.

- "Experimental autoimmune encephalomyelitis" (EAE), an animal model of brain inflammation.

- Progressive encephalomyelitis with rigidity and myoclonus (PERM) – A kind of stiff person syndrome.

- AIDS related encephalomyelitis, caused by opportunistic Human T-lymphotropic virus type III (HTLV-III) infection.

Treatment of TSP involves corticosteroids to help with inflammation. Though any success with corticosteroids is short-lived, with symptoms worsened as the dosage is reduced. A synthetic derivative, 17-alpha-ethinyltestosterone, can be used to treat Tropical spastic paraparesis, improvement in motor and bladder function was reported but not sustainable.

Mogamulizumab, an anti-CCR4 IgG1 monoclonal antibody, is also being researched as a possible treatment for Tropical spastic paraparesis. The antibody reduces HTLV-1 proviral load and production of proinflammatory cytokines. Valproic acid has also succeeded in reducing the proviral load of HTLV-1 (though clinical benefits were minimal or none). A further combination of valproic acid and zidovudine has demonstrated a decrease in proviral loads (in animals).

The virus is most often spread by person to person contact with the stool or saliva of the infected person. Two types of vaccines have been developed to prevent the occurrence and spread of the poliomyelitis virus. The first is an inactivated, or killed, form of the virus and the second is an attenuated, or weakened, form of the virus. The development of vaccines has successfully eliminated the disease from the United States. There are continued vaccination efforts in the U.S. to maintain this success rate as this disease still occurs in some areas of the world.

Oropouche Fever has no cure or specific therapy so treatment is done by relieving the pain of the symptoms through symptomatic treatment. Certain oral analgesic and anti-inflammatory agents can help treat headaches and body pains. In extreme cases of oropouche fever the drug, Ribavirin is recommended to help against the virus. This is called antiviral therapy. Treatments also consist of drinking lots of fluids to prevent dehydration.

Asprin is not a recommended choice of drug because it can reduce blood clotting and may aggravate the hemorrhagic effects and prolong recovery time.

The infection is usually self-limiting and complications are rare. This illness usually lasts for about a week but in extreme cases can be prolonged. Patients usually recover fully with no long term ill effects. There have been no recorded fatalities resulting from oropouche fever.

As of 2017, eleven disease-modifying medications have been approved by regulatory agencies for relapsing-remitting multiple sclerosis (RRMS). They are interferon beta-1a, interferon beta-1b, glatiramer acetate, mitoxantrone, natalizumab, fingolimod, teriflunomide, dimethyl fumarate, alemtuzumab, daclizumab, and ocrelizumab.

Their cost effectiveness as of 2012 is unclear. In May 2016 the FDA approved daclizumab for the treatment of relapsing multiple sclerosis in adults, with requirements for postmarketing studies and submission of a formal risk evaluation and mitigation strategy. In March 2017 the FDA approved ocrelizumab, a humanized anti-CD20 monoclonal antibody, as a treatment for RRMS, with requirements for several Phase IV clinical trials.

In RRMS they are modestly effective at decreasing the number of attacks. The interferons and glatiramer acetate are first-line treatments and are roughly equivalent, reducing relapses by approximately 30%. Early-initiated long-term therapy is safe and improves outcomes. Natalizumab reduces the relapse rate more than first-line agents; however, due to issues of adverse effects is a second-line agent reserved for those who do not respond to other treatments or with severe disease. Mitoxantrone, whose use is limited by severe adverse effects, is a third-line option for those who do not respond to other medications. Treatment of clinically isolated syndrome (CIS) with interferons decreases the chance of progressing to clinical MS. Efficacy of interferons and glatiramer acetate in children has been estimated to be roughly equivalent to that of adults. The role of some newer agents such as fingolimod, teriflunomide, and dimethyl fumarate, as of 2011, is not yet entirely clear.

As of 2017, rituximab was widely used off-label to treat RRMS.

There is a wide range of treatments for central nervous system diseases. These can range from surgery to neural rehabilitation or prescribed medications.

As of 2017, rituximab has been widely used off-label to treat progressive primary MS. In March 2017 the FDA approved ocrelizumab, as a treatment for primary progressive MS, the first drug to gain that approval, with requirements for several Phase IV clinical trials.

, only one medication, mitoxantrone, has been approved for secondary progressive MS. In this population tentative evidence supports mitoxantrone moderately slowing the progression of the disease and decreasing rates of relapses over two years.

The treatment of TB meningitis is isoniazid, rifampicin, pyrazinamide and ethambutol for two months, followed by isoniazid and rifampicin alone for a further ten months. Steroids help reduce the risk of death in those without HIV. Steroids can be used in the first six weeks of treatment, A few people may require immunomodulatory agents such as thalidomide. Hydrocephalus occurs as a complication in about a third of people with TB meningitis. The addition of aspirin may reduce or delay mortality, possibly by reducing complications such as infarcts.

In one case, cloxacillin, ceftriaxone, and amphotericin B were tried.

Two patients survived after being successfully treated with a therapy consisting of flucytosine, pentamidine, fluconazole, sulfadiazine and azithromycin. Thioridazine was also given. Successful treatment in these cases was credited to "awareness of "Balamuthia" as the causative agent of encephalitis and early initiation of antimicrobial therapy."

Exercise is a promising mechanism of prevention and treatment for various diseases characterized by neuroinflammation. Aerobic exercise is used widely to reduce inflammation in the periphery. Exercise has been shown to decreases proliferation of microglia in the brain, decrease hippocampal expression of immune-related genes, and reduce expression of inflammatory cytokines such as TNF-α.

Even with treatment, the condition is often fatal, and there are very few recorded survivors, almost all of whom suffered permanent neurocognitive deficits. Antifungal drugs including ketoconazole, miconazole, 5-flucytosine and pentamidine have been shown to be effective against GAE-causing organisms in laboratory tests.

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.

No definite standard treatment have been set. This is because treatments of the disease has been poorly studied as of 2014. Often in cases of inflammatory parenchymal disease, "corticosteroids should be given as infusions of

intravenous methylprednisolone followed by a slowly tapering course of oral steroids". It is suggested that therapy should be continued for a period of time even when the symptoms get suppressed because early relapse may occur. Sometimes, the medical doctors may suggest a different steroid depending on the nature of the disease, the severity, and the response to steroids. According to several studies, parenchymal NBD patients successfully suppress the symptoms with the prescribed steroids. As for non-parenchymal patients, there is no general consensus on how to treat the disease. The reason is that the mechanisms of cerebral venous thrombosis in BD are still poorly understood. Some doctors use anti-coagulants to prevent a clot. On the other hand, some doctors only give steroids and immunosuppressants alone.

Management of neuropsychiatric lupus is similar to the management of neuropsychiatric disease in patients without lupus. Treatment depends on the underlying causes of a patient’s disease, and may include immunosuppressants, anticoagulants, and symptomatic therapy.

People whose condition was caused by a recent viral infection should make a full recovery without treatment in a few months. Fine motor skills, such as handwriting, typically have to be practised in order to restore them to their former ability. In more serious cases, strokes, bleeding or infections may sometimes cause permanent symptoms.

There is no specific treatment for the canine distemper. As with measles, the treatment is symptomatic and supportive. The supportive care is geared towards treating fluid/electrolyte imbalances, neurological symptoms, and preventing any secondary bacterial infections. Examples include administering fluids, electrolyte solutions, analgesics, anticonvulsants, broad spectrum antibiotics, antipyretics, parenteral nutrition and nursing care.
