Binswanger's disease has no cure and has been shown to be the most severe impairment of all of the vascular dementias. The best way to manage the vascular risk factors that contribute to poor perfusion in the brain is to treat the cause, such as chronic hypertension or diabetes. It has been shown that current Alzheimer’s medication, donepezil (trade name Aricept), may help Binswanger’s Disease patients as well . Donepezil increases the acetylcholine in the brain through a choline esterase inhibitor which deactivates the enzyme that breaks down acetylcholine. Alzheimer as well as Binswanger patients have low levels of acetylcholine and this helps to restore the normal levels of neurotransmitters in the brain. This drug may improve memory, awareness, and the ability to function. If no medical interception of the disease is performed then the disease will continue to worsen as the patient ages due to the continuing atrophy of the white matter from whatever was its original cause.

No medications have been shown to prevent or cure dementia. Medications may be used to treat the behavioural and cognitive symptoms but have no effect on the underlying disease process.

Acetylcholinesterase inhibitors, such as donepezil, may be useful for Alzheimer disease and dementia in Parkinson's, DLB, or vascular dementia. The quality of the evidence however is poor and the benefit is small. No difference has been shown between the agents in this family. In a minority of people side effects include a slow heart rate and fainting.

As assessment for an underlying cause of the behavior is a needed before prescribing antipsychotic medication for symptoms of dementia. Antipsychotic drugs should be used to treat dementia only if non-drug therapies have not worked, and the person's actions threaten themselves or others. Aggressive behavior changes are sometimes the result of other solvable problems, that could make treatment with antipsychotics unnecessary. Because people with dementia can be aggressive, resistant to their treatment, and otherwise disruptive, sometimes antipsychotic drugs are considered as a therapy in response. These drugs have risky adverse effects, including increasing the patient's chance of stroke and death. Generally, stopping antipsychotics for people with dementia does not cause problems, even in those who have been on them a long time.

N-methyl-D-aspartate (NMDA) receptor blockers such as memantine may be of benefit but the evidence is less conclusive than for AChEIs. Due to their differing mechanisms of action memantine and acetylcholinesterase inhibitors can be used in combination however the benefit is slight.

While depression is frequently associated with dementia, selective serotonin reuptake inhibitors (SSRIs) do not appear to affect outcomes.

The use of medications to alleviate sleep disturbances that people with dementia often experience has not been well researched, even for medications that are commonly prescribed. In 2012 the American Geriatrics Society recommended that benzodiazepines such as diazepam, and non-benzodiazepine hypnotics, be avoided for people with dementia due to the risks of increased cognitive impairment and falls. Additionally, there is little evidence for the effectiveness of benzodiazepines in this population. There is no clear evidence that melatonin or ramelteon improves sleep for people with dementia due to Alzheimer's disease. There is limited evidence that a low dose of trazodone may improve sleep, however more research is needed.

There is no solid evidence that folate or vitamin B12 improves outcomes in those with cognitive problems. Statins also have no benefit in dementia. Medications for other health conditions may need to be managed differently for a person who also has a diagnosis of dementia. The MATCH-D criteria can help identify ways that a diagnosis of dementia changes medication management for other health conditions. It is unclear if there is a link between blood pressure medication and dementia. There is a possibility that people may experience an increase in cardiovascular-related events if these medications are withdrawn.

Aromatherapy and massage have unclear evidence. There have been studies on the efficacy and safety of cannabinoids in relieving behavioral and psychological symptoms of dementia.

Omega-3 fatty acid supplements from plants or fish sources do not appear to benefit or harm people with mild to moderate Alzheimer's disease. It is unclear if taking omega-3 fatty acid supplements can improve other types of dementia.

The treatment to battle the disease chorea-acanthocytosis is completely symptomatic. For example, Botulinum toxin injections can help to control orolingual dystonia.

Deep Brain Stimulation is a treatment that has varied effects on the people suffering from the symptoms of this disease, for some it has helped in a large way and for other people it did not help whatsoever, it is more effective on specific symptoms of the disease. Patients with chorea-acanthocytosis should undergo a cardiac evaluation every 5 years to look for cardiomyopathy.

Binswanger's disease, also known as subcortical leukoencephalopathy, is a form of small vessel vascular dementia caused by damage to the white brain matter. White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age. This disease is characterized by loss of memory and intellectual function and by changes in mood. These changes encompass what are known as executive functions of the brain. It usually presents between 54 and 66 years of age, and the first symptoms are usually mental deterioration or stroke.

It was described by Otto Binswanger in 1894, and Alois Alzheimer first used the phrase "Binswanger's disease" in 1902. However, Olszewski is credited with much of the modern-day investigation of this disease which began in 1962.

Batten disease is a terminal illness; the FDA has approved Brineura (cerliponase alfa) as a treatment for a specific form of Batten disease. Brineura is the first FDA-approved treatment to slow loss of walking ability (ambulation) in symptomatic pediatric patients 3 years of age and older with late infantile neuronal ceroid lipofuscinosis type 2 (CLN2), also known as tripeptidyl peptidase-1 (TPP1) deficiency. Palliative treatment is symptomatic and supportive.

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:

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

The twins require the use of wheelchairs for mobility and are unable to speak without the assistance of electronic speaking aids. They experience persistent and painful muscle spasms which are worsened by emotional distress. They are currently living with their parents, with the assistance of hospice workers. Doctors continue to administer tests to the twins in search of a treatment.

Pick's disease is a term that can be used in two different ways. It has traditionally been used as a term for a group of neurodegenerative diseases with symptoms attributable to frontal and temporal lobe dysfunction. Common symptoms that are noticed early are personality and emotional changes, as well as deterioration of language. This condition is now more commonly called frontotemporal dementia by professionals, and the use of "Pick's disease" as a clinical diagnosis has fallen out of fashion. The second use of the term (and the one now used among professionals) is to mean a specific pathology that is one of the causes of frontotemporal lobar degeneration. These two uses have previously led to confusion among professionals and patients and so its use should be restricted to the specific pathological subtype described below. It is also known as Pick disease and PiD (not to be confused with pelvic inflammatory disease (PID) or Parkinson's disease (PD)). A defining characteristic of the disease is build-up of tau proteins in neurons, accumulating into silver-staining, spherical aggregations known as "Pick bodies".

Adult-onset Still's disease is treated with anti-inflammatory drugs. Steroids such as prednisone are used to treat severe symptoms of Still's. Other commonly used medications include hydroxychloroquine, penicillamine, azathioprine, methotrexate, etanercept, anakinra, cyclophosphamide, adalimumab, rituximab, and infliximab.

Newer drugs target interleukin-1 (IL-1), particularly IL-1β. A randomized, multicenter trial reported better outcomes in a group of 12 patients treated with anakinra than in a group of 10 patients taking other disease-modifying antirheumatic drugs. Other anti-IL1β drugs are being developed, including canakinumab and rilonacept.

The condition "juvenile-onset Still's disease" is now usually grouped under juvenile rheumatoid arthritis. However, there is some evidence that the two conditions are closely related.

In June 1987, a phase-I clinical trial was launched at Weill Cornell Medical College of Cornell University to study a gene therapy method for treatment of the signs and symptoms of LINCL. The experimental drug works by delivering a gene transfer vector called AAV2CUhCLN2 to the brain. Although the trial is not matched, randomized, or blinded and lacked a contemporaneous placebo/sham control group, assessment of the primary outcome variable suggests a slowing of progression of LINCL in the treated children.

Researchers believe the neurological deficits common in JNCL could be due to overactive AMPA receptors in the cerebellum. To test this hypothesis, researchers administered AMPA antagonist drugs into affected mice. The motor skills of the affected mice showed significant improvement after the antagonist treatment, which supported the hypothesis that the neurological deficits in JNCL are due to overactive AMPA receptors. This research could eventually help to alleviate neurological deficits of JNCL in humans.

In November 2006, after receiving FDA clearance, neurosurgeon Nathan Selden, pediatrician Bob Steiner, and colleagues at Doernbecher Children's Hospital at Oregon Health and Science University began a clinical study in which purified neural stem cells were injected into the brain of Daniel Kerner, a six-year-old child with Batten disease, who had lost the ability to walk and talk. This patient was the first of six to receive the injection of a stem cell product from StemCells Inc., a Palo Alto biotech company. These are believed to be the first-ever transplants of fetal stem cells into the human brain. By early December, the child had recovered well enough to return home, and some signs of speech returning were reported. Daniel Kerner died on April 12, 2010. The main goal of phase-I clinical trials, however, was to investigate the safety of transplantation. Overall, the phase-I data demonstrated that high doses of human neural stem cells, delivered by a direct transplantation procedure into multiple sites within the brain, followed by 12 months of immunosuppression, were well tolerated by all six patients enrolled in the trial. The patients’ medical, neurological, and neuropsychological conditions, following transplantation, appeared consistent with the normal course of the disease.

Mycophenolate mofetil is being tested to determine its ability to safely slow or halt neurodegeneration. A non-randomised safety and efficacy trial of a gene transfer vector is underway.

Currently Sandhoff disease does not have any standard treatment and does not have a cure. However, a person suffering from the disease needs proper nutrition, hydration, and maintenance of clear airways. To reduce some symptoms that may occur with Sandhoff disease, the patient may take anticonvulsants to manage seizures or medications to treat respiratory infections, and consume a precise diet consisting of puree foods due to difficulties swallowing. Infants with the disease usually die by the age of 3 due to respiratory infections. The patient must be under constant surveillance because they can suffer from aspiration or lack the ability to change from the passageway to their lungs versus their stomach and their spit travels to the lungs causing bronchopneumonia. The patient also lacks the ability to cough and therefore must undergo a treatment to shake up their body to remove the mucus from the lining of their lungs. Medication is also given to patients to lessen their symptoms including seizures.

Currently the government is testing several treatments including N-butyl-deoxynojirimycin in mice, as well as stem cell treatment in humans and other medical treatments recruiting test patients.

The first treatment for Fabry's disease was approved by the US FDA on April 24, 2003. Fabrazyme (agalsidase beta, or Alpha-galactosidase) was licensed to the Genzyme Corporation. It is an enzyme replacement therapy (ERT) designed to provide the enzyme the patient is missing as a result of a genetic malfunction. The drug is expensive — in 2012, Fabrazyme's annual cost was about US$200,000 per patient, which is unaffordable to many patients around the world without enough insurance. ERT is not a cure, but can allow improved metabolism and partially prevent disease progression, as well as potentially reverse some symptoms.

The pharmaceutical company Shire manufactures agalsidase alpha (which differs in the structure of its oligosaccharide side chains) under the brand name Replagal as a treatment for Fabry's disease, and was granted marketing approval in the EU in 2001. FDA approval was applied for the United States. However, Shire withdrew their application for approval in the United States in 2012, citing that the agency will require additional clinical trials before approval.

Clinically the two products are generally perceived to be similar in effectiveness. Both are available in Europe and in many other parts of the world, but treatment costs remain very high.

Besides these drugs, a gene therapy treatment is also available from the Canadian Institutes of Health. Other treatments (oral chaperone therapy -Amicus-, plant-based ERT -Protalix-, substrate reduction therapy -Sanofi-Genzyme-, bio-better ERT -Codexis-, gene editing solution -Sangamo- are currently being researched.

Pain associated with Fabry disease may be partially alleviated by ERT in some patients, but pain management regimens may also include analgesics, anticonvulsants, and nonsteroidal anti-inflammatory drugs, though the latter are usually best avoided in renal disease.

The symptoms of Pick's disease include difficulty in language and thinking, efforts to dissociate from family, behavioral changes, unwarranted anxiety, irrational fears, CBD (Compulsive buying disorder, or oniomania), impaired regulation of social conduct (e.g., breaches of etiquette, vulgar language, tactlessness, , misperception), passivity, low motivation (aboulia), inertia, over-activity, pacing and wandering. It is a characteristic of Pick’s disease that dysfunctional, argumentative, or hostile social conduct is initially exhibited towards family members and not initially exhibited in a workplace or neutral environment. The changes in personality allow doctors to distinguish between Pick's disease and Alzheimer's disease. Pick's disease is one of the causes of the clinical syndrome of frontotemporal lobar degeneration which has three subtypes. Pick's disease pathology is associated more with the frontotemporal dementia and progressive nonfluent aphasia subtypes than the semantic dementia subtype.

Current treatment is aimed at easing the symptoms, reducing inflammation, and controlling the immune system. The quality of the evidence for treating the oral ulcers associated with Behçet's disease, however, is poor.

High-dose corticosteroid therapy is often used for severe disease manifestations. Anti-TNF therapy such as infliximab has shown promise in treating the uveitis associated with the disease. Another Anti-TNF agent, etanercept, may be useful in people with mainly skin and mucosal symptoms.

Interferon alpha-2a may also be an effective alternative treatment, particularly for the genital and oral ulcers as well as ocular lesions. Azathioprine, when used in combination with interferon alpha-2b also shows promise, and colchicine can be useful for treating some genital ulcers, erythema nodosum, and arthritis.

Thalidomide has also been used due to its immune-modifying effect. Dapsone and rebamipide have been shown, in small studies, to have beneficial results for mucocutaneous lesions.

Given its rarity, the optimal treatment for acute optic neuropathy in Behçet's disease has not been established. Early identification and treatment is essential. Response to ciclosporin, periocular triamcinolone, and IV methylprednisone followed by oral prednisone has been reported although relapses leading to irreversible visual loss may occur even with treatment. Immunosuppressants such as interferon alpha and tumour necrosis factor antagonists may improve though not completely reverse symptoms of ocular Behçet's disease, which may progress over time despite treatment. When symptoms are limited to the anterior chamber of the eye prognosis is improved. Posterior involvement, particularly optic nerve involvement, is a poor prognostic indicator. Secondary optic nerve atrophy is frequently irreversible. Lumbar puncture or surgical treatment may be required to prevent optic atrophy in cases of intracranial hypertension refractory to treatment with immunomodulators and steroids.

IVIG could be a treatment for severe or complicated cases.

Although there is no known cure for Krabbe disease, bone marrow transplantation has been shown to benefit cases early in the course of the disease. Generally, treatment for the disorder is symptomatic and supportive. Physical therapy may help maintain or increase muscle tone and circulation. Cord blood transplants have been successful in stopping the disease as long as they are given before overt symptoms appear.

Currently, there is no cure for Urbach–Wiethe disease although there are some ways to individually treat many of its symptoms. There has been some success with oral dimethyl sulfoxide (DMSO) and intralesional heparin, but this is not true in all cases. D-penicillamine has also shown promise, but has yet to have been used extensively. There are also some reports of patients being treated with etretinate, a drug typically prescribed to treat psoriasis. In some cases, calcifications in the brain can lead to abnormal electrical activity among neurons. Some patients are given anti-seizure medication to help deal with these abnormalities. Tracheostomy is often used to relieve upper respiratory tract infections. Carbon dioxide laser surgery of thickened vocal cords and beaded eyelid papules have improved these symptoms for patients. The discovery of the mutations of the ECM1 gene has opened the possibility of gene therapy or a recombinant EMC1 protein for Urbach–Wiethe disease treatment, but neither of these two options are currently available.

As Tay–Sachs disease is a deficiency of β-hexosaminidase A, by getting a substance that increases its activity, people affected will not be deteriorating as fast or not at all. While for infantile Tay–Sachs disease, there is no β-hexosaminidase A so then the treatment would be ineffective. However, for people affected by Late-Onset Tay–Sachs disease, they still have β-hexosaminidase A. The drug Pyrimethamine has been shown to increase activity of β-hexosaminidase A. However, the increased levels of β-hexosaminidase A still fall far short of the desired "10% of normal HEXA", above which the phenotypic symptoms begin to disappear.

As of 2010 there was no treatment that addressed the cause of Tay–Sachs disease or could slow its progression; people receive supportive care to ease the symptoms and extend life by reducing the chance of contracting infections. Infants are given feeding tubes when they can no longer swallow. In late-onset Tay–Sachs, medication (e.g., lithium for depression) can sometimes control psychiatric symptoms and seizures, although some medications (e.g., tricyclic antidepressants, phenothiazines, haloperidol, and risperidone) are associated with significant adverse effects.

Treatment varies with the type of vascular disease; in the case of renal artery disease, information from a meta-analysis indicated that balloon angioplasty results in improvement of diastolic blood pressure and a reduction in antihypertensive drug requirements. In the case of peripheral artery disease, preventing complications is important; without treatment, sores or gangrene (tissue death) may occur. Among the treatments are:

- Quitting smoking

- Lowering cholesterol

- Lower blood pressure

- Lower blood glucose

- Physical activity

There is no way to reverse VHL mutations, but early recognition and treatment of specific manifestations of VHL can substantially decrease complications and improve quality of life. For this reason, individuals with VHL disease are usually screened routinely for retinal angiomas, CNS hemangioblastomas, clear-cell renal carcinomas and pheochromocytomas. CNS hemangioblastomas are usually surgically removed if they are symptomatic. Photocoagulation and cryotherapy are usually used for the treatment of symptomatic retinal angiomas, although anti-angiogenic treatments may also be an option. Renal tumours may be removed by a partial nephrectomy or other techniques such as radiofrequency ablation.

Bright's disease was historically 'treated' with warm baths, blood-letting, squill, digitalis, mercuric compounds, opium, diuretics, laxatives, and dietary therapy, including abstinence from alcoholic drinks, cheese and red meat. Arnold Ehret was diagnosed with Bright's disease and pronounced incurable by 24 of Europe's most respected doctors; he designed "The Mucusless Diet Healing System", which apparently cured his illness. William Howard Hay, MD had the illness and, it is claimed, cured himself using the Hay diet.

Surgical options are considered the final option for treating Kyrle disease. The use of a carbon dioxide laser, electrocautery, or cryosurgery to rid of limited lesions can be implemented. Patients with darker skin must take extra precaution as these options can lead to dyspigmentation. In addition, performing on patients that had Kyrle disease due to diabetes mellitus or have poor circulation can lead to poor healing.

Isotretinoin, high doses of vitamin A and tretinoin cream can be utilized. Also, emollients, oral antihistamines, and antipruritic creams that contain menthol and camphor may be helpful because the lesions can become very itchy.
