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.

Attacks are treated with short courses of high dosage intravenous corticosteroids such as methylprednisolone IV.

Plasmapheresis can be an effective treatment when attacks progress or do not respond to corticosteroid treatment. Clinical trials for these treatments contain very small numbers, and most are uncontrolled, though some report high success percentage.

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.

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.

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

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.

At the time of the report there was no known treatment for the disease; specifically, it was not established whether steroids were helpful or harmful. Other techniques such as plasmaphoresis, intravenous immunoglobulin, and experimental antiviral drugs have been attempted on a trial basis, but have not been reported to be effective. On November 7 the CDC issued "Interim Considerations for Clinical Management of Patients with Acute Flaccid Myelitis", based on "consensus guidance drawn from experts in infectious diseases, neurology, pediatrics, critical care medicine, public health epidemiology and virology." Mark Sawyer of the American Academy of Pediatrics, who contributed to the guidance, was quoted by the organization's newsletter: The most important issue summarized in the document is that there is no clear evidence that therapies intended to modify the immune system (e.g., corticosteroids, immune globulin, plasmapheresis) have a beneficial effect in this condition. Plasmapheresis is specifically not recommended because the potential for harm is significant in the absence of any evidence of benefit.

Six of ten children in Denver were sent home for outpatient treatment; some with mild symptoms have recovered from temporary limb weakness, while the fate of those more severely affected remains unclear. Intensive physical therapy and occupational therapy may be beneficial for recovery.

The treatment and prognosis of myelopathy depends on the underlying cause: myelopathy caused by infection requires medical treatment with pathogen specific antibiotics. Similarly, specific treatments exist for multiple sclerosis, which may also present with myelopathy. As outlined above, the most common form of myelopathy is secondary to degeneration of the cervical spine. Newer findings have challenged the existing controversy with respect to surgery for cervical spondylotic myelopathy by demonstrating that patients benefit from surgery.

Initial care in the hospital, as in the prehospital setting, aims to ensure adequate airway, breathing, cardiovascular function, and spinal immobilization. Imaging of the spine to ascertain presence of SCI may need to wait if emergency surgery is needed to stabilize a life-threatening injury. Acute SCI merits treatment in an intensive care unit, especially injuries to the cervival spinal cord. Patients with SCI need repeated neurological assessments and treatment by neurosurgeons.

If the systolic blood pressure falls below 90 mmHg within days of the injury, blood supply to the spinal cord may be reduced, resulting in further damage. Thus it is important to maintain the blood pressure using a central venous catheter, intravenous fluids, and vasopressors, and to treat cases of shock. Mean arterial blood pressure is measured and kept at 85 to 90 mmHg for seven days after injury. The treatment for shock from blood loss (hypovolemic shock) is different from that for neurogenic shock, and could harm people with the latter type, so it is necessary to determine why someone is in shock. However it is also possible for both causes to exist at the same time. Another important aspect of care is prevention of hypoxia (insufficient oxygen in the bloodstream), which could deprive the spinal cord of much-needed oxygen. People with cervical injuries may experience a dangerously slowed heart rate; treatment to speed it up include atropine and electrical cardiac pacing.

Swelling can cause further damage to the spinal cord by reducing the blood supply and causing ischemia, which can give rise to an ischemic cascade with a release of toxins that damages neurons. Thus treatment is often geared toward limiting this secondary injury. People are sometimes treated with drugs to reduce swelling. The corticosteroid drug methylprednisolone is commonly used within eight hours of the injury, but its use is controversial because of side effects. Studies have shown high dose methylprednisolone may improve outcomes if given within 6 hours of injury. However, the improvement shown by clinical trials has been inconclusive, and comes at the cost of increased risk of serious infection or sepsis, gastrointestinal bleeding, and pneumonia. Thus organizations that set clinical guidelines have increasingly stopped recommending methylprednisolone in the treatment of acute SCI.

Surgery may be necessary, e.g. to relieve excess pressure on the cord, to stabilize the spine, or to put vertebrae back in their proper place. In cases involving instability or compression, failing to operate can lead to worsening of the condition. Surgery is also necessary when something is pressing on the cord, such as bone fragments, blood, material from ligaments or intervertebral discs, or a lodged object from a penetrating injury. Although the ideal timing of surgery is still debated, studies have found that earlier surgical intervention (within 24 hours of injury) is associated with better outcomes. Sometimes a patient has too many other injuries to be a surgical candidate this early. Surgery is controversial because it has potential complications (such as infection), so in cases where it is not clearly needed (e.g. the cord is being compressed), doctors must decide whether to perform surgery based on aspects of the patient's condition and their own beliefs about its risks and benefits.

In cases where a more conservative approach is chosen, bed rest, cervical collars, immobilizing devices, and optionally traction are used. Surgeons may opt to put traction on the spine to remove pressure from the spinal cord by putting dislocated vertebrae back into alignment, but herniation of intervertebral disks may prevent this technique from relieving pressure. "Gardner-Wells tongs" are one tool used to exert spinal traction to reduce a fracture or dislocation and to immobilize the affected areas.

SCI patients often require extended treatment in specialized spinal unit or an intensive care unit. The rehabilitation process typically begins in the acute care setting. Usually the inpatient phase lasts 8–12 weeks and then the outpatient rehabilitation phase lasts 3–12 months after that, followed by yearly medical and functional evaluation. Physical therapists, occupational therapists, recreational therapists, nurses, social workers, psychologists and other health care professionals work as a team under the coordination of a physiatrist to decide on goals with the patient and develop a plan of discharge that is appropriate for the person’s condition.

In the acute phase physical therapists focus on the patient’s respiratory status, prevention of indirect complications (such as pressure ulcers), maintaining range of motion, and keeping available musculature active.

For people whose injuries are high enough to interfere with breathing, there is great emphasis on airway clearance during this stage of recovery. Weakness of respiratory muscles impairs the ability to cough effectively, allowing secretions to accumulate within the lungs. As SCI patients suffer from reduced total lung capacity and tidal volume, physical therapists teach them accessory breathing techniques (e.g. apical breathing, glossopharyngeal breathing) that typically are not taught to healthy individuals. Physical therapy treatment for airway clearance may include manual percussions and vibrations, postural drainage, respiratory muscle training, and assisted cough techniques. Patients are taught to increase their intra-abdominal pressure by leaning forward to induce cough and clear mild secretions. The quad cough technique is done lying on the back with the therapist applying pressure on the abdomen in the rhythm of the cough to maximize expiratory flow and mobilize secretions. Manual abdominal compression is another technique used to increase expiratory flow which later improves coughing. Other techniques used to manage respiratory dysfunction include respiratory muscle pacing, use of a constricting abdominal binder, ventilator-assisted speech, and mechanical ventilation.

The amount of functional recovery and independence achieved in terms of activities of daily living, recreational activities, and employment is affected by the level and severity of injury. The Functional Independence Measure (FIM) is an assessment tool that aims to evaluate the function of patients throughout the rehabilitation process following a spinal cord injury or other serious illness or injury. It can track a patient's progress and degree of independence during rehabilitation. People with SCI may need to use specialized devices and to make modifications to their environment in order to handle activities of daily living and to function independently. Weak joints can be stabilized with devices such as ankle-foot orthoses (AFOs) and knee-AFOs, but walking may still require a lot of effort. Increasing activity will increase chances of recovery.

People with mild to moderate pain can be treated with over-the-counter pain medications. Topical lotions containing calamine can be used on the rash or blisters and may be soothing. Occasionally, severe pain may require an opioid medication, such as morphine. Once the lesions have crusted over, capsaicin cream (Zostrix) can be used. Topical lidocaine and nerve blocks may also reduce pain. Administering gabapentin along with antivirals may offer relief of postherpetic neuralgia.

Treatment is symptomatic and supportive. Children with hydrocephalus often need a ventriculoperitoneal shunt. Nucleoside analog ribavirin is used in some cases due to the inhibitory effect the agent has "in vitro" on arenaviruses. However, there is not sufficient evidence for efficacy in humans to support routine use. The only survivor of a transplant-associated LCMV infection was treated with ribavirin and simultaneous tapering of the immunosuppressive medications. Early and intravenous ribavirin treatment is required for maximal efficacy, and it can produce considerable side effects. Ribavirin has not been evaluated yet in controlled clinical trials.

Use of ribavirin during pregnancy is generally not recommended, as some studies indicate the possibility of teratogenic effects. If aseptic meningitis, encephalitis, or meningoencephalitis develops in consequence to LCMV, hospitalization and supportive treatment may be required. In some circumstances, anti-inflammatory drugs may also be considered. In general, mortality is less than one percent.

Antiviral drugs may reduce the severity and duration of shingles; however, they do not prevent postherpetic neuralgia. Of these drugs, aciclovir has been the standard treatment, but the new drugs valaciclovir and famciclovir demonstrate similar or superior efficacy and good safety and tolerability. The drugs are used both for prevention (for example in HIV/AIDS) and as therapy during the acute phase. Complications in immunocompromised individuals with shingles may be reduced with intravenous aciclovir. In people who are at a high risk for repeated attacks of shingles, five daily oral doses of aciclovir are usually effective.

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.

The acute uveitis phase of VKH is usually responsive to high-dose oral corticosteroids; parenteral administration is usually not required. However, ocular complications may require an subtenon or intravitreous injection of corticosteroids or bevacizumab. In refractory situations, other immunosuppressives such as cyclosporine, or tacrolimus, antimetabolites (azathioprine, mycophenolate mofetil or methotrexate), or biological agents such as intravenous immunoglobulins (IVIG) or infliximab may be needed.

Paracetamol (acetaminophen) and NSAIDs, such as ibuprofen, may be used to reduce fever and pain. Prednisone, a corticosteroid, while used to try to reduce throat pain or enlarged tonsils, remains controversial due to the lack of evidence that it is effective and the potential for side effects. Intravenous corticosteroids, usually hydrocortisone or dexamethasone, are not recommended for routine use but may be useful if there is a risk of airway obstruction, a very low platelet count, or hemolytic anemia.

There is little evidence to support the use of antivirals such as aciclovir and valacyclovir although they may reduce initial viral shedding. Although antivirals are not recommended for people with simple infectious mononucleosis, they may be useful (in conjunction with steroids) in the management of severe EBV manifestations, such as EBV meningitis, peripheral neuritis, hepatitis, or hematologic complications.

Although antibiotics exert no antiviral action they may be indicated to treat bacterial secondary infections of the throat, such as with streptococcus (strep throat). However, ampicillin and amoxicillin are not recommended during acute Epstein–Barr virus infection as a diffuse rash may develop.

Infectious mononucleosis is generally self-limiting, so only symptomatic or supportive treatments are used. The need for rest and return to usual activities after the acute phase of the infection may reasonably be based on the person's general energy levels. Nevertheless, in an effort to decrease the risk of splenic rupture experts advise avoidance of contact sports and other heavy physical activity, especially when involving increased abdominal pressure or the Valsalva maneuver (as in rowing or weight training), for at least the first 3–4 weeks of illness or until enlargement of the spleen has resolved, as determined by a treating physician.

Visual prognosis is generally good with prompt diagnosis and aggressive immunomodulatory treatment. Inner ear symptoms usually respond to corticosteroid therapy within weeks to months; hearing usually recovers completely. Chronic eye effects such as cataracts, glaucoma, and optic atrophy can occur. Skin changes usually persist despite therapy.

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

There are no prospective randomized controlled trials studying therapies for relapsing polychondritis. Evidence for efficacy of treatments is based on case reports and series of small groups of patients.

For mild cases limited to joint pain or arthritis, oral nonsteroidal anti-inflammatory drugs (NSAIDs) may be used. Other treatments typically involve medications to suppress the immune system. Corticosteroids are frequently used for more serious disease. Steroid-sparing medications such as azathioprine or methotrexate may be used to minimize steroid doses and limit the side effects of steroids. For severe disease cyclophosphamide is often given in addition to high dose intravenous steroids.

Transverse myelitis is a neurological condition in which the spinal cord is inflamed. The inflammation damages nerve fibers, and causes them to lose their myelin coating leading to decreased electrical conductivity in the central nervous system. "Transverse" implies that the inflammation extends across the entire width of the spinal cord. Partial transverse myelitis and partial myelitis are terms used to define inflammation of the spinal cord that affects part of the width of the spinal cord.

Most people recover from West Nile virus without treatment. No specific treatment is available for WNV infection. In mild cases over the counter pain relievers can help ease mild headaches and muscle aches in adults. In severe cases treatment consists of supportive care that often involves hospitalization, intravenous fluids, pain medication, respiratory support, and prevention of secondary infections.

Neuroborreliosis, also known as Lyme neuroborreliosis (LNB), is a disorder of the central nervous system. A neurological manifestation of Lyme disease, neuroborreliosis is caused by a systemic infection of spirochetes of the genus "Borrelia." Symptoms of the disease include erythema migrans and flu-like symptoms. The microbiological progression of the disease is similar to that of neurosyphilis, another spirochetal infection.

Myelopathy describes any neurologic deficit related to the spinal cord. When due to trauma, it is known as (acute) spinal cord injury. When inflammatory, it is known as myelitis. Disease that is vascular in nature is known as vascular myelopathy. The most common form of myelopathy in human, "cervical spondylotic myelopathy (CSM)", is caused by arthritic changes (spondylosis) of the cervical spine, which result in narrowing of the spinal canal (spinal stenosis) ultimately causing compression of the spinal cord. In Asian populations, spinal cord compression often occurs due to a different, inflammatory process affecting the posterior longitudinal ligament.
