Treatment is variable depending on individuals. Some treatments work extremely well with some patients and not at all with others. Some treatments include Therapy with thiamine and vitamin B complex. Alcohol consumption should be stopped. Some patients survive, but with residual brain damage and dementia. Others remain in comas that eventually lead to death. Nutritional counseling is also recommended. Treatment is often similar to those administered for Wenicke-Korsakoff syndrome or for alcoholism.

Type A has 21% mortality rate and an 81% long-term disability rate. Type B has a 0% mortality rate and a 19% long-term disability rate.

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 of Sydenham's Chorea is based on the following principles:

1. The first tenet of treatment is to eliminate the streptococcus at a primary, secondary and tertiary level. Strategies involve the adequate treatment of throat and skin infections, with a course of penicillin when Sydenham's Chorea is newly diagnosed, followed by long-term penicillin prophylaxis. Behavioural and emotional changes may precede the movement disorders in a previously well child.

2. Treatment of movement disorders. Therapeutic efforts are limited to palliation of the movement disorders. Haloperidol is frequently used because of its anti-dopaminergic effect. It has serious potential side-effects, e.g., tardive dyskinesia. In a study conducted at the RFC, 25 out of 39 patients on haloperidol reported side-effects severe enough to cause the physician or parent to discontinue treatment or reduce the dose. Other medications which have been used to control the movements include pimozide, clonidine, valproic acid, carbamazepine and phenobarbitone.

3. Immunomodulatory interventions include steroids, intravenous immunoglobulins, and plasma exchange. Patients may benefit from treatment with steroids; controlled clinical trials are indicated to explore this further.

4. There are several historical case series reporting successful treatment of Sydenham's Chorea by inducing fever.

Marchiafava–Bignami disease is a progressive neurological disease of alcoholism, characterized by corpus callosum demyelination and necrosis and subsequent atrophy. The disease was first described in 1903 by the Italian pathologists Amico Bignami and Ettore Marchiafava in an Italian Chianti drinker. In this autopsy, Marchiafava and Bignami noticed that the middle two-thirds of the corpus callosum were necrotic. It is very difficult to diagnose and there is no specific treatment right now. Until 2008 only around 300 cases had been reported. If caught early enough, most patients survive.

Supportive treatment is the only intervention for acute cerebellar ataxia of childhood. Symptoms may last as long as 2 or 3 months.

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 currently no specific therapy. Intravenous fluids and treatment of the hepatic encephalopathy may help. Increasing dietary levels of branched chain amino acids and feeding low protein diets can help signs of hepatic encephalopathy, which is often accomplished by feeding small amounts of grain and/or beet pulp, and removing high-protein feedstuffs such as alfalfa hay. Grazing on non-legume grass may be acceptable if it is late summer or fall, although the horse should only be permitted to eat in the evening so as to avoid photosensitization. Due to the risk of gastric impaction, stomach size should be monitored.

Sedation is minimized and used only to control behavior that could lead to injury of the animal and to allow therapeutic procedures, and should preferably involve a sedative other than a benzodiazepine. Stressing the animal should be avoided if at all possible. Plasma transfusions may be needed if spontaneous bleeding occurs, to replace clotting factors. Antibiotics are sometimes prescribed to prevent bacterial translocation from the intestines. Antioxidants such as vitamin E, B-complex vitamins, and acetylcysteine may be given. High blood ammonia is often treated with oral neomycin, often in conjunction with lactulose, metronidazole and probiotics, to decrease production and absorption of ammonia from the gastrointestinal tract.

Acute GPP typically requires inpatient management including both topical and systemic therapy, and supportive measures. Systemic glucocorticoid withdrawal is a common causative agent. Withdrawal or administration of certain drugs in the patient's previous medication regimen may be required. Oral retinoids are the most effective treatment, and are considered first line. Cyclosporine or infliximab may be required for particularly acute cases.

Treatment of OBS varies with the causative disorder or disease. It is important to note that it is not a primary diagnosis and a cause needs to be sought out and treated.

Intravenously administered glucocorticoids, such as prednisone, are the standard of care in acute GvHD and chronic GVHD. The use of these glucocorticoids is designed to suppress the T-cell-mediated immune onslaught on the host tissues; however, in high doses, this immune-suppression raises the risk of infections and cancer relapse. Therefore, it is desirable to taper off the post-transplant high-level steroid doses to lower levels, at which point the appearance of mild GVHD may be welcome, especially in HLA mis-matched patients, as it is typically associated with a graft-versus-tumor effect.. Cyclosporine and tacrolimus are inhibitors of calcineurin. Both substances are structurally different but have the same mechanism of action. Cyclosporin binds to the cytosolic protein Peptidyl-prolyl cis-trans isomerase A (known as cyclophilin), while tacrolimus binds to the cytosolic protein Peptidyl-prolyl cis-trans isomerase FKBP12. These complexes inhibit calcineurin, block dephosphorylation of the transcription factor NFAT of activated T-cells and its translocation into the nucleus. Standard prophylaxis involves the use of cyclosporine for six months with methotrexate. Cyclosporin levels should be maintained above 200 ng/ml.

Other substances that have been studied for GvHD prophylaxis include, for example: sirolimus, pentostatin and alemtuzamab.

In August 2017 the US FDA approved ibrutinib to treat chronic GvHD after failure of one or more other systemic treatments.

There is no cure for HCP caused by the deficient activity of coproporphyrinogen oxidase. Treatment of the acute symptoms of HCP is the same as for other acute porphyrias. Intravenous hemin (as heme arginate or hematin) is the recommended therapy for acute attacks. Acute attacks can be severe enough to cause death if not treated quickly and correctly. Hospitalization is typically required for administration of hemin, and appropriate drug selection is key to avoid exacerbating symptoms with drugs that interact poorly with porphyrias. Proper drug selection is most difficult when it comes to treatment of the seizures that can accompany HCP, as most anti-seizure medications can make the symptoms worse. Gabapentin and levetiracetam are two anti-seizure drugs that are thought to be safe.

In patients where management of symptoms is difficult even with hemin, liver transplant is an option before the symptoms have progressed to advanced paralysis. Combined liver and kidney transplants are sometimes undertaken in patients with renal failure.

Long term treatment of acute porphyrias is centered on the avoidance of acute attacks by eliminating precipitating factors, such as drugs, dietary changes, and infections. Females often have attacks coincident with their menstrual cycle, which can be managed effectively with hormonal birth control. Because of the reduced penetrance of HCP, family members of a patient may carry the same mutation without ever presenting with symptoms. Molecular analysis of "CPOX" is the best way to identify these patients, as they will not express a biochemical phenotype on laboratory testing unless they are symptomatic. Identification of asymptomatic patients allows them to adjust their lifestyle to avoid common triggering factors.

Seizures often accompany this disease. Most seizure medications exacerbate this condition. Treatment can be problematic: barbiturates especially must be avoided. Some benzodiazepines are safe and, when used in conjunction with newer anti-seizure medications such as gabapentin, offer a possible regimen for seizure control. Gabapentin has the additional feature of aiding in the treatment of some kinds of neuropathic pain.

Magnesium sulfate and bromides have also been used in porphyria seizures; however, development of status epilepticus in porphyria may not respond to magnesium alone. The addition of hematin or heme arginate has been used during status epilepticus.

There are no approved treatments for canine pancreatitis. Treatment for this disease is supportive, and may require hospitialization to attend to the dog's nutritional and fluid needs, pain management, and addressing any other disease processes (infection, diabetes, etc.) while letting the pancreas heal on its own. Treatment often involves "resting" the pancreas for a short period of time by nil per os/nothing per os (NPO)/nil by mouth (NBM), in which the patient receives no food or fluids by mouth, but is fed and hydrated by intravenous fluids and a feeding tube. Dehydration is also managed by the use of fluid therapy. However, a specialist from Texas A&M University has stated "There is no evidence whatsoever that withholding food has any beneficial effect." Other specialists have agreed with his opinion.

Canine pancreatitis is complex, often limiting the ability to approach the disease.

Intravenous N-acetylcysteine has been found to be beneficial in both acetaminophen toxicity and non-acetaminophen-related acute liver failure.

Currently treatment of ARN consists of antiviral therapy administered orally. Typical antiviral agents used include famciclovir, valganciclovir, and valacyclovir. While on these medications, a patient's kidney function should be watched. Some physician's also may administer the antiviral agents via intravitreal delivery. Though controversial, some physicians administer steroids (prednisone) and antithrombotic therapy (aspirin).

Some commonly admistered antiviral agents are as follows:

- Acyclovir

- Famciclovir

- Valacyclovir

- Gancicilovir

- Valganciclovir

During an acute flare-up, therapy is targeted at reducing the inflammation present, and dilating the pupil. Mydriasis is important, as pupillary constriction is the primary reason for pain. Anti-inflammatory therapy is usually given both systemically, often in the form of flunixin meglumine, and topically, as prednisolone acetate. The mydriatic of choice is atropine. In the periods between acute attacks, no therapy has been shown to be beneficial.

A low fat diet is indicated. The use of drugs which are known to have an association with pancreatitis should be avoided. Some patients benefit from the use of pancreatic enzymes on a supplemental basis. One study indicated that 57 percent of dogs, who were followed for six months after an acute pancreatitis attack, either continued to exhibit inflammation of the organ or had decreased acinar cell function, even though they had no pancreatitis symptoms.

Bacterial and fungal infections are common in ALF, with one study demonstrating culture-proven infection in 80% of ALF patients. Defective cellular and humoral immunity as well as presence of indwelling catheters, coma, broad-spectrum antibiotics, and medications that suppress immunity all predispose to infection. Localizing symptoms of infection such as fever and sputum production are frequently absent and the only clues to an underlying infectious process may be worsening of encephalopathy or renal function. There must be a low threshold for obtaining frequent cultures (blood, urine, and sputum), chest radiographs, and paracentesis. Bacteria that enter through the skin, such as streptococci and staphylococci, tend to predominate. Aggressive surveillance is essential as prophylactic antibiotics have shown little benefit. Fungal infections, particularly in the setting of broad-spectrum antibiotics, are also common, and disseminated fungemia is a poor prognostic sign.

There are a large number of clinical trials either ongoing or recently completed in the investigation of graft-versus-host disease treatment and prevention. Currently, there are no reliable molecular markers reflecting the onset or clinical course of aGVHD. However, it has been shown that genes responsible for cytokine signaling, inflammatory response, and regulation of cell cycle are differentially expressed in patinets with fatal GvHD versus „indolent“ GvHD.

On May 17, 2012, Osiris Therapeutics announced that Canadian health regulators approved Prochymal, its drug for acute graft-versus host disease in children who have failed to respond to steroid treatment. Prochymal is the first stem cell drug to be approved for a systemic disease.

In January 2016, Mesoblast released results of a Phase2 clinical trial on 241 children with acute Graft-versus-host disease, that was not responsive to steroids. The trial was of a mesenchymal stem cell therapy known as remestemcel-L or MSC-100-IV. Survival rate was 82% (vs 39% of controls) for those who showed some improvement after 1 month, and in the long term 72% (vs 18% of controls) for those that showed little effect after 1 month.

While there is no prevention for ARN, exposing a patient to antiviral agents in the earlier phases of the outbreak tend to decrease the duration of the active phase of the disease. Taking antiviral agents after the issue is resolved seems to lessen the chance of it spreading to the other eye.

Pain is severe, frequently out of proportion to physical signs, and often requires the use of opiates to reduce it to tolerable levels. Pain should be treated as early as medically possible. Nausea can be severe; it may respond to phenothiazine drugs but is sometimes intractable. Hot baths and showers may lessen nausea temporarily, though caution should be used to avoid burns or falls.

Systemic corticosteroids such as (prednisone) can produce rapid improvement and are the “gold standard” for treatment. The temperature, white blood cell count, and eruption improve within 72 hours. The skin lesions clear within 3 to 9 days. Abnormal laboratory values rapidly return to normal. There are, however, frequent recurrences. Corticosteroids are tapered within 2 to 6 weeks to zero.

Resolution of the eruption is occasionally followed by milia and scarring. The disease clears spontaneously in some patients. Topical and/or intralesional corticosteroids may be effective as either monotherapy or adjuvant therapy.

Oral potassium iodide or colchicine may induce rapid resolution.

Patients who have a potential systemic infection or in whom corticosteroids are contraindicated can use these agents as a first-line therapy.

In one study, indomethacin, 150 mg per day, was given for the first week, and 100 mg per day was given for 2 additional weeks. Seventeen of 18 patients had a good initial response; fever and arthralgias were markedly attenuated within 48 hours, and eruptions cleared between 7 and 14 days.

Patients whose cutaneous lesions continued to develop were successfully treated with prednisone (1 mg/kg per day). No patient had a relapse after discontinuation of indomethacin.

Other alternatives to corticosteroid treatment include dapsone, doxycycline, clofazimine, and cyclosporine. All of these drugs influence migration and other functions of neutrophils.

Horses that suffer from this disease can never be considered cured, although they can be managed by careful use of the therapy described above, and fast detection of new flare-ups. If the disease is not properly treated, it will eventually lead to blindness.

Viliuisk Encephalomyelitis (VE) is a fatal progressive neurological disorder found only in the Sakha (Iakut/Yakut) population of central Siberia. About 15 new cases are reported each year. VE is a very rare disease and little research has been conducted. The causative agents, origin of the disease, and involved candidate genes are currently unknown, but much research has been done in pursuit of the answers.

Those inflicted with the disease survive for a period of only a few months to several years. VE follows three main courses of infection: an acute form, a sub-acute form subsiding into a progressive form, and a chronic form. Initially, the infected patients experience symptoms such as: severe headaches, delirium, lethargy, meningism, bradykinesia, and incoordination. A small percentage of patients die during the acute phase as result of a severe coma. In all cases the disease is fatal.

Fifty percent of patients with acute Sydenham's chorea spontaneously recover after two to six months whilst mild or moderate chorea or other motor symptoms can persist for up to and over two years in some cases. Sydenham's is also associated with psychiatric symptoms with obsessive compulsive disorder being the most frequent manifestation.
