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

There is no known cure for MSA and management is primarily supportive.

Ongoing care from a neurologist specializing in "movement disorders" is recommended as the complex symptoms of MSA are often not familiar to less-specialized health care professionals.

One particularly serious problem, the drop in blood pressure upon standing up (with risk of fainting and thus injury from falling) often responds to fludrocortisone, a synthetic mineralocorticoid. Another common drug treatment is midodrine (an alpha-agonist). Non-drug treatments include "head-up tilt" (elevating the head of the whole bed by about 10 degrees), salt tablets or increasing salt in the diet, generous intake of fluids, and pressure (elastic) stockings. Avoidance of triggers of low blood pressure (such as hot weather, alcohol, and dehydration) are crucial.

Hospice/homecare services can be very useful as disability progresses.

Levodopa (L-Dopa), a drug used in the treatment of Parkinson's disease, improves parkinsonian symptoms in a small percentage of MSA patients. A recent trial reported that only 1.5% of MSA patients experienced a less than 50% improvement when taking levodopa, and even this was a transient effect lasting less than one year. Poor response to L-Dopa has been suggested as a possible element in the differential diagnosis of MSA from Parkinson's disease.

A November, 2008 study conducted in Europe failed to find an effect for the drug riluzole in treating MSA or PSP.

Management by rehabilitation professionals (physiatrists, physiotherapists, occupational therapists, speech therapists, and others) for problems with walking/movement, daily tasks, and speech problems is essential.

Physiotherapy can help to maintain the patient’s mobility and will help to prevent contractures. Instructing patients in gait training will help to improve their mobility and decrease their risk of falls. A physiotherapist may also prescribe mobility aids such as a cane or a walker to increase the patient’s safety. Other ways a physiotherapist can help to improve the patient’s safety are to teach them to move and transfer from sitting to standing slowly to decrease risk of falls and limit the effect of postural hypotension. Instruction in ankle pumping helps to return blood in the legs to the systemic circulation. To further control the postural hypotension, raising the head of the bed by 8 in (20.3 cm) while sleeping may be indicated as well as the use of elastic compression garments.

Speech and language therapists may assist in assessing, treating and supporting speech (dysarthria) and swallowing difficulties (dysphagia). Early intervention of swallowing difficulties is particularly useful to allow for discussion around tube feeding further in the disease progression.{doubtful - citation needed} At some point in the progression of the disease, fluid and food modification may be suggested. Speech changes mean that alternative communication may be needed, for example communication aids or word charts.

Social workers and occupational therapists can also help with coping with disability through the provision of equipment and home adaptations, services for caregivers and access to healthcare services, both for the person with MSA as well as family caregivers.

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.

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.

Every disease has different signs and symptoms. Some of them are persistent headache; pain in the face, back, arms, or legs; an inability to concentrate; loss of feeling; memory loss; loss of muscle strength; tremors; seizures; increased reflexes, spasticity, tics; paralysis; and slurred speech. One should seek medical attention if affected by these.

Concerning more serious afflictions, the complex origins of myoclonus may be treated with multiple drugs, which have a limited effect individually, but greater when combined with others that act on different brain pathways or mechanisms. Treatment is most effective when the underlying cause is known, and can be treated as such. Some drugs being studied in different combinations include clonazepam, sodium valproate, piracetam, and primidone. Hormonal therapy may improve responses to antimyoclonic drugs in some people.

Some studies have shown that doses of 5-hydroxytryptophan (5-HTP) leads to improvement in patients with some types of action myoclonus and PME. These differences in the effect of 5-HTP on patients with myoclonus have not yet been explained.

Many of the drugs used for myoclonus, such as barbiturates, phenytoin and primidone, are also used to treat epilepsy. Barbiturates slow down the central nervous system and cause tranquilizing or antiseizure effects. Phenytoin and primidone are effective antiepileptics drugs, although phenytoin can cause liver failure or have other harmful long-term effects in patients with PME. Sodium valproate is an alternative therapy for myoclonus and can be used either alone or in combination with clonazepam. Some people have adverse reactions to clonazepam and/or sodium valproate.

When patients are taking multiple medications, the discontinuation of drugs suspected of causing myoclonus and treatment of metabolic derangements may resolve some cases of myoclonus. When pharmacological treatment is indicated anticonvulsants are the main line of treatment. Paradoxical reactions to treatment are notable. Drugs which most people respond to may in other individuals worsen their symptoms. Sometimes this leads to the mistake of increasing the dose, rather than decreasing or stopping the drug. Treatment of myoclonus focuses on medications that may help reduce symptoms. Drugs used include sodium valproate, clonazepam, the anticonvulsant levetiracetam, and piracetam. Dosages of clonazepam usually are increased gradually until the patient improves or side effects become harmful. Drowsiness and loss of coordination are common side effects. The beneficial effects of clonazepam may diminish over time if the patient develops a tolerance to the drug.

In forms of myoclonus where only a single area is affected, and even in a few other various forms, Botox injections (OnabotulinumtoxinA) may be helpful. The chemical messenger responsible for triggering the involuntary muscle contractions is blocked by the Botulinum toxins of the Botox.

Surgery is also a viable option for treatment if the symptoms are caused by a tumor or lesion in the brain or spinal cord. Surgery may also correct symptoms in those where myoclonus affects parts of the face or ear. While DBS is still being studied for use with myoclonus, Deep Brain Stimulation has also been tried in those with this and other movement disorders.

The treatment of dysautonomia can be difficult; since it is made up of many different symptoms, a combination of drug therapies is often required to manage individual symptomatic complaints. Therefore, if an autoimmune neuropathy is the case, then treatment with immunomodulatory therapies is done, or if diabetes mellitus is the cause, control of blood glucose is important. Treatment can include proton-pump inhibitors and H2 receptor antagonists used for digestive symptoms such as acid reflux.

For the treatment of genitourinary autonomic neuropathy medications may include sildenafil (a guanine monophosphate type-5 phosphodiesterase inhibitor). For the treatment of hyperhidrosis, anticholinergic agents such as trihexyphenidyl or scopolamine can be used, also intracutaneous injection of botulinum toxin type A can be used for management in some cases.

Balloon angioplasty, a procedure referred to as transvascular autonomic modulation, is specifically not approved for the treatment of autonomic dysfunction.

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.

Although the brain and spinal cord are surrounded by tough membranes, enclosed in the bones of the skull and spinal vertebrae, and chemically isolated by the blood–brain barrier, they are very susceptible if compromised. Nerves tend to lie deep under the skin but can still become exposed to damage. Individual neurons, and the neural networks and nerves into which they form, are susceptible to electrochemical and structural disruption. Neuroregeneration may occur in the peripheral nervous system and thus overcome or work around injuries to some extent, but it is thought to be rare in the brain and spinal cord.

The specific causes of neurological problems vary, but can include genetic disorders, congenital abnormalities or disorders, infections, lifestyle or environmental health problems including malnutrition, and brain injury, spinal cord injury or nerve injury. The problem may start in another body system that interacts with the nervous system. For example, cerebrovascular disorders involve brain injury due to problems with the blood vessels (cardiovascular system) supplying the brain; autoimmune disorders involve damage caused by the body's own immune system; lysosomal storage diseases such as Niemann-Pick disease can lead to neurological deterioration. The National Institutes of Health recommend considering the evaluation of an underlying celiac disease in people with unexplained neurological symptoms, particularly peripheral neuropathy or ataxia.

In a substantial minority of cases of neurological symptoms, no neural cause can be identified using current testing procedures, and such "idiopathic" conditions can invite different theories about what is occurring.

A neurological disorder is any disorder of the nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms. Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain and altered levels of consciousness. There are many recognized neurological disorders, some relatively common, but many rare. They may be assessed by neurological examination, and studied and treated within the specialities of neurology and clinical neuropsychology.

Interventions for neurological disorders include preventative measures, lifestyle changes, physiotherapy or other therapy, neurorehabilitation, pain management, medication, or operations performed by neurosurgeons. The World Health Organization estimated in 2006 that neurological disorders and their sequelae (direct consequences) affect as many as one billion people worldwide, and identified health inequalities and social stigma/discrimination as major factors contributing to the associated disability and suffering.

Most patients reported in the literature have been given treatments suitable for autoimmune neurological diseases, such as corticosteroids, plasmapheresis and/or intravenous immunoglobulin, and most have made a good recovery. The condition is too rare for controlled trials to have been undertaken.

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.

Articulation problems resulting from dysarthria are treated by speech language pathologists, using a variety of techniques. Techniques used depend on the effect the dysarthria has on control of the articulators. Traditional treatments target the correction of deficits in rate (of articulation), prosody (appropriate emphasis and inflection, affected e.g. by apraxia of speech, right hemisphere brain damage, etc.), intensity (loudness of the voice, affected e.g. in hypokinetic dysarthrias such as in Parkinson's), resonance (ability to alter the vocal tract and resonating spaces for correct speech sounds) and phonation (control of the vocal folds for appropriate voice quality and valving of the airway). These treatments have usually involved exercises to increase strength and control over articulator muscles (which may be flaccid and weak, or overly tight and difficult to move), and using alternate speaking techniques to increase speaker intelligibility (how well someone's speech is understood by peers). With the speech language pathologist, there are several skills that are important to learn; safe chewing and swallowing techniques, avoiding conversations when feeling tired, repeat words and syllables over and over in order to learn the proper mouth movements, and techniques to deal with the frustration while speaking. Depending on the severity of the dysarthria, another possibility includes learning how to use a computer or flip cards in order to communicate more effectively.

More recent techniques based on the principles of motor learning (PML), such as LSVT (Lee Silverman voice treatment) speech therapy and specifically LSVT may improve voice and speech function in PD. For Parkinson's, aim to retrain speech skills through building new generalised motor programs, and attach great importance to regular practice, through peer/partner support and self-management. Regularity of practice, and when to practice, are the main issues in PML treatments, as they may determine the likelihood of generalization of new motor skills, and therefore how effective a treatment is.

Augmentative and alternative communication (AAC) devices that make coping with a dysarthria easier include speech synthesis and text-based telephones. These allow people who are unintelligible, or may be in the later stages of a progressive illness, to continue to be able to communicate without the need for fully intelligible speech.

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.

There is currently no cure for FD and death occurs in 50% of the affected individuals by age 30. There are only two treatment centers, one at New York University Hospital and one at the Sheba Medical Center in Israel. One is being planned for the San Francisco area.

The survival rate and quality of life have increased since the mid-1980s mostly due to a greater understanding of the most dangerous symptoms. At present, FD patients can be expected to function independently if treatment is begun early and major disabilities avoided.

A major issue has been aspiration pneumonia, where food or regurgitated stomach content would be aspirated into the lungs causing infections. Fundoplications (by preventing regurgitation) and gastrostomy tubes (to provide nonoral nutrition) have reduced the frequency of hospitalization.

Other issues which can be treated include FD crises, scoliosis, and various eye conditions due to limited or no tears.

An FD crisis is the body's loss of control of various autonomic nervous system functions including blood pressure, heart rate, and body temperature. Both short-term and chronic periodic high or low blood pressure have consequences and medication is used to stabilize blood pressure.

Although the FD-causing gene has been identified and it seems to have tissue specific expression, there is no definitive treatment at present.

Treatment of FD remains preventative, symptomatic and supportive. FD does not express itself in a consistent manner. The type and severity of symptoms displayed vary among patients and even at different ages on the same patients. So patients should have specialized individual treatment plans. Medications are used to control vomiting, eye dryness, and blood pressure. There are some commonly needed treatments including:

1. Artificial tears: using eye drops containing artificial tear solutions (methylcellulose)

2. Feeding: Maintenance of adequate nutrition, avoidance of aspiration; thickened formula and different shaped nipples are used for baby.

3. Daily chest physiotherapy (nebulization, bronchodilators, and postural drainage): for Chronic lung disease from recurrent aspiration pneumonia

4. Special drug management of autonomic manifestations such as vomiting: intravenous or rectal diazepam (0.2 mg/kg q3h) and rectal chloral hydrate (30 mg/kg q6h)

5. Protecting the child from injury (coping with decreased taste, temperature and pain perception)

6. Combating orthostatic hypotension: hydration, leg exercise, frequent small meals, a high-salt diet, and drugs such as fludrocortisone.

7. Treatment of orthopedic problems (tibial torsion and spinal curvature)

8. Compensating for labile blood pressures

There is no cure for Familial Dysautonomia.

Proper treatment of autonomic dysreflexia involves administration of anti-hypertensives along with immediate determination and removal of the triggering stimuli. Often, sitting the patient up and dangling legs over the bedside can reduce blood pressures below dangerous levels and provide partial symptom relief. Tight clothing and stockings should be removed. Straight catheterization of the bladder every 4 to 6 hrs, or relief of a blocked urinary catheter tube may resolve the problem. The rectum should be cleared of stool impaction, using anaesthetic lubricating jelly. If the noxious precipitating trigger cannot be identified, drug treatment is needed to decrease elevating intracranial pressure until further studies can identify the cause.

Drug treatment includes the rapidly acting vasodilators, including sublingual nitrates or oral clonidine. Ganglionic blockers are also used to control sympathetic nervous system outflow. Topical nitropaste is a convenient and safe treatment—an inch or two can be applied to the chest wall, and wiped off when blood pressures begin to normalize. Autonomic dysreflexia is abolished temporarily by spinal or general anaesthesia. These treatments are used during obstetric delivery of a woman with autonomic dysreflexia.

Because neuroinflammation has been associated with a variety of neurodegenerative diseases, there is increasing interest to determine whether reducing inflammation will reverse neurodegeneration. Inhibiting inflammatory cytokines, such as IL-1β, decreases neuronal loss seen in neurodegenerative diseases. Current treatments for multiple sclerosis include interferon-B, Glatiramer actetate, and Mitoxantrone, which function by reducing or inhibiting T Cell activation, but have the side effect of systemic immunosuppression In Alzheimer's disease, the use of non-steroidal anti-inflammatory drugs decreases the risk of developing the disease. Current treatments for Alzheimer's disease include NSAIDs and glucocorticoids. NSAIDs function by blocking conversion of prostaglandin H2 into other prostaglandins (PGs) and thromboxane (TX). Prostoglandins and thromboxane act as inflammatory mediators and increase microvascular permeability.

Cyclophosphamide is a drug often used in the treatment of lymphomas and works by slowing or stopping cell growth. It also works as an immunosuppressant by decreasing the body’s immune response to various diseases and conditions. This drug has been found to make significant improvements in people with anti-MAG neuropathy by relieving sensory loss and helping to improve quality of life in a few short months. There is, however, a risk of cancer because of this treatment and is therefore not used on a regular basis.

Chlorambucil is a chemotherapy drug normally used to treat leukemia as it is often used as an immunosuppressant drug, and prednisone is a steroid that has also been found to be particularly effective as an immunosuppressant. This combination of drugs has minimal to no benefits in most patients, but a small number do see small improvements such as decreased tremors. This combination has not been very effective in more severe cases, though, and is not considered a long term therapy.

Common treatments for Dercum's disease is directed towards treating the individual symptoms. Pain relief medication may be administered to temporarily reduce the discomfort in the patient. Cortisone shots have also been shown to be effective in temporarily reducing the chronic pain. Surgical removal of the damaged adipose tissue can be effective, but often the disease will recur. Once a person has Dercum's disease then they will likely have pain for the rest of their life. Studies have only shown temporary pain relief in patients. Long term the person with Dercum's disease will need to take prescription drugs for pain relief to ensure quality of life. The disease will cause chronic and severe pain for the rest of a persons life. There are several holistic treatments for this disease. Acupuncture, hypnosis and cognitive behavior therapy have been attempted to help people with Dercum's disease.

Few convincing large studies on the treatment of Dercum's disease have been conducted. Most of the different treatment strategies that exist are based on case reports. Currently, there is a lack of scientific data on the use of integrative therapies for the treatment or prevention of Dercum's disease. Not enough studies have been done to substantiate that diet and supplements could help with the disease.

Treatment methods include the following modalities:

Research on myoclonus is supported through the National Institute of Neurological Disorders and Stroke (NINDS). The primary focus of research is on the role of neurotransmitters and receptors involved in the disease. Identifying whether or not abnormalities in these pathways cause myoclonus may help in efforts to develop drug treatments and diagnostic tests. Determining the extent that genetics play in these abnormalities may lead to potential treatments for their reversal, potentially correcting the loss of inhibition while enhancing mechanisms in the body that would compensate for their effects.

Surgical excision of fatty tissue deposits around joints (liposuction) has been used in some cases. It may temporarily relieve symptoms although recurrences often develop.

A range of medications that act on the central nervous system has been found to be useful in managing neuropathic pain. Commonly used treatments include tricyclic antidepressants (such as nortriptyline or amitriptyline), the serotonin-norepinephrine reuptake inhibitor (SNRI) medication duloxetine, and antiepileptic therapies such as gabapentin, pregabalin, or sodium valproate. Few studies have examined whether nonsteroidal anti-inflammatory drugs are effective in treating peripheral neuropathy.

Symptomatic relief for the pain of peripheral neuropathy may be obtained by application of topical capsaicin. Capsaicin is the factor that causes heat in chili peppers. The evidence suggesting that capsaicin applied to the skin reduces pain for peripheral neuropathy is of moderate to low quality and should be interpreted carefully before using this treatment option. Local anesthesia often is used to counteract the initial discomfort of the capsaicin. Some current research in animal models has shown that depleting neurotrophin-3 may oppose the demyelination present in some peripheral neuropathies by increasing myelin formation.

High-quality evidence supports the use of cannabis for neuropathic pain.
