UV irradiation can be utilized after curetting the hyperkeratosis with a combination medication treatment of oral retinoids, psoralen and Ultraviolet A radiation.

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.

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.

Sweating causes lesions to form, but lesions aggravated by sweat usually return to "normal" fairly quicklyavoiding sweat is not a reason to avoid exercise. Minor outbreaks can be controlled with prescription strength topical cortisone creams. More severe eruptions usually clear up after treatment for one to three months with Accutane or tetracycline. If these fail or the outbreak is severe, PUVA phototherapy treatments, antifungal pills and cortisone injections are alternatives.

Some research has suggested a correlation of Grover's disease with mercury toxicity in which case Dimercaptosuccinic acid might help.

Urbach–Wiethe disease is typically not a life-threatening condition. The life expectancy of these patients is normal as long as the potential side effects of thickening mucosa, such as respiratory obstruction, are properly addressed. Although this may require a tracheostomy or carbon dioxide laser surgery, such steps can help ensure that individuals with Urbach–Wiethe disease are able to live a full life. Oral dimethyl sulfoxide (DMSO) has been shown to reduce skin lesions, helping to minimize discomfort for these individuals.

There is no specific treatment for Farber disease. Corticosteroids may be prescribed to relieve pain. Bone marrow transplants may improve granulomas (small masses of inflamed tissue) on patients with little or no lung or nervous system complications. Older patients may have granulomas surgically reduced or removed.

Since phytanic acid is not produced in the human body, individuals with Refsum disease are commonly placed on a phytanic acid-restricted diet and avoid the consumption of fats from ruminant animals and certain fish, such as tuna, cod, and haddock. Grass feeding animals and their milk are also avoided. Recent research has shown that CYP4 isoform enzymes could help reduce the over-accumulation of phytanic acid "in vivo". Plasmapheresis is another medical intervention used to treat patients. This involves the filtering of blood to ensure there is no accumulation of phytanic acid.

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.

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.

There are no specific treatments for lipid storage disorders; however, there are some highly effective enzyme replacement therapies for people with type 1 Gaucher disease and some patients with type 3 Gaucher disease. There are other treatments such as the prescription of certain drugs like phenytoin and carbamazepine to treat pain for patients with Fabry disease. Furthermore, gene thereapies and bone marrow transplantation may prove to be effective for certain lipid storage disorders. Diet restrictions do not help prevent the buildup of lipids in the tissues.

Infants with Schindler disease tend to die within 4 years of birth, therefore, treatment for this form of the disease is mostly palliative. However, Type II Schindler disease, with its late onset of symptoms, is not characterized by neurological degeneration. There is no known cure for Schindler disease, but bone marrow transplants have been trialed, as they have been successful in curing other glycoprotein disorders.

In ruminant animals, the gut fermentation of consumed plant materials liberates phytol, a constituent of chlorophyll, which is then converted to phytanic acid and stored in fats. Although humans cannot derive significant amounts of phytanic acid from the consumption of chlorophyll present in plant materials, it has been proposed that the great apes (bonobos, chimpanzees, gorillas, and orangutans) can derive significant amounts of phytanic acid from the hindgut fermentation of plant materials.

No cures for lysosomal storage diseases are known, and treatment is mostly symptomatic, although bone marrow transplantation and enzyme replacement therapy (ERT) have been tried with some success. ERT can minimize symptoms and prevent permanent damage to the body. In addition, umbilical cord blood transplantation is being performed at specialized centers for a number of these diseases. In addition, substrate reduction therapy, a method used to decrease the production of storage material, is currently being evaluated for some of these diseases. Furthermore, chaperone therapy, a technique used to stabilize the defective enzymes produced by patients, is being examined for certain of these disorders. The experimental technique of gene therapy may offer cures in the future.

Ambroxol has recently been shown to increase activity of the lysosomal enzyme glucocerebrosidase, so it may be a useful therapeutic agent for both Gaucher disease and Parkinson's disease. Ambroxol triggers the secretion of lysosomes from cells by inducing a pH-dependent calcium release from acidic calcium stores. Hence, relieving the cell from accumulating degradation products is a proposed mechanism by which this drug may help.

The first approach, which is the best approach at an effective management practice would be to eradicate or severely damage the Mountain and Cherry Leafhopper population because the leafhoppers are the number one vectors for this pathogen. To do this, pesticides (i.e. acephate, bifenthrin, cyfluthrin) could be applied or biological control (predators of the leafhopper) could be used. There should be a pre-season application of control measures as well as a post-season application. This is to maximize the effort at controlling both types of leafhoppers (Cherry and Mountain), thus cutting down the starting inoculum at both stages in the life cycle.

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.

There are numerous steps one has to take to try to manage the disease as best as possible. The aim is at prevention because once the pathogen reaches the cherry trees, disease will surely ensue and there is no cure or remedy to prevent the loss of fruit production as well as the ultimate death of the tree.

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 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.

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.

Usually no treatment is needed. Folic acid supplementation may help produce normal red blood cells and improve the symptoms of anemia

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:

Currently, antibiotic drugs such as penicillin or tetracycline are the only effective methods for disease treatment. Within wild populations, disease control consists of reducing the amount of bacterial spores present in the environment. This can be done by removing contaminated carcasses and scat.

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.
