There have been no major breakthroughs in the treatment of PKAN, with most pharmacologic treatments focusing on the easing or temporary relieving of PKAN’s symptoms. Iron chelating agents have been used somewhat successfully in retarding the disorder, but they have not been a significant success.

Current research focuses on the future use of high dose pantothenate, the PANK2 enzyme substrate, in possibly alleviating symptoms as well as the further development of iron chelating agents that may be better aimed at reaching the central nervous system and working to better remove excess iron from the individual’s system.

Complications may result from the medication used to treat symptoms. Immobility from the disease can also lead to skin breakdown, respiratory infections, and blood clots, among others.

Due to neuroferritinopathy’s genetic etiology, the disorder is not currently curable. Furthermore, progression of the disorder is unable to be effectively halted. Therefore current treatment focuses on managing symptoms of the disorder.

No medication is available to treat all symptoms. Botox has been shown to help with focal dystonia. The dopamine depleter Tetrabenazine shown to help with involuntary movements. Symptoms affecting movement (dystonia) have also been treated with L-Dopa, orphenadrine, benzhexol, sulpiride, diazepam, clonazepam, and deanol. Parkinsonian symptoms were not decreased by L-Dopa. Iron supplements should be avoided.

Treatment includes the use of iron chelating agents (such as desferrioxamine) to lower serum ferritin concentration, brain and liver iron stores, and to prevent progression of neurologic symptoms. This, combined with fresh-frozen human plasma (FFP) effectively in decreasing liver iron content. Repetitive use of FFP can even improve neurologic symptoms. Antioxidants such as vitamin E can be used simultaneously to prevent tissue damage to the liver and pancreas.

Currently treatment is only symptomatic and palliative. Treatment for manifestations, such as seizures, dystonia, sleep disorders, depression and anxiety, can be effectively managed. Physical and occupational therapy is recommended to help patients retain fine motor function for as long as possible Recent progress has been made in the application of enzyme-replacement, gene, and stem cell therapies for patients.

On April 27, 2017, the U.S. Food and Drug Administration approved Brineura (cerliponase alfa) as the first specific treatment for NCL. Brineura is enzyme replacement therapy manufactured through recombinant DNA technology. The active ingredient in Brineura, cerliponase alpha, is intended to slow loss of walking ability 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. Brineura is administered into the cerebrospinal fluid by infusion via a surgically implanted reservoir and catheter in the head (intraventricular access device).

Survival rates for those diagnosed with typical PKAN is 11.18 years with a standard deviation of 7.8 years.

Currently there is no widely accepted treatment that can cure, slow down, or halt the symptoms in the great majority of patients with NCL. However, seizures may be controlled or reduced with use of anti-epileptic drugs. Additionally, physical, speech, and occupational therapies may help affected patients retain functioning for as long as possibleSeveral experimental treatments are under investigation.

At the moment there are no therapies specifically targeting the underlying cause of AGS. Current treatments address the symptoms, which can be varied both in scope and severity. Many patients benefit from tube-feeding. Drugs can be administered to help with seizures / epilepsy. The treatment of chilblains remains problematic, but particularly involves keeping the feet / hands warm. Physical therapy, including the use of splints can help to prevent contractures and surgery is sometimes required. Botox (botulinium toxin) has sometimes caused severe immune reactions in some AGS patients, and the high risk of possible further brain damage must be considered before giving Botox. Occupational therapy can help with development, and the use of technology (e.g. Assistive Communication Devices) can facilitate communication. Patients should be regularly screened for treatable conditions, most particularly glaucoma and endocrine problems (especially hypothyroidism). The risk versus benefit of giving immunizations also must be considered, as some AGS patients have high immune responses or flares that cause further brain damage from immunizations but other patients have no problems with immunizations; on the other hand, AGS patients have died from illnesses that can be immunized against, so the family must consider the risk vs. benefit of each immunization vs. risk of the actual virus if they choose not to immunize. As of 2017, there are current drug trials being conducted that may lead to drug treatments for AGS.

An effective treatment has yet to be found. In many cases electrical stimulation of the globus pallidus has been shown to produce improvement of dystonia severity, however it has not been shown to delay neurodegeneration. There is often overlap in the phenotypes of the symptoms both between different NBIA disorders and between NBIA and other disorders, leading to misdiagnoses. Treatments typically treat or ameliorate the symptoms and do not address the accumulation of iron. Psychotherapy, such as dopaminergic drugs, anticholinergics, tetrabenazine, is often used to treat the symptoms but does not improve the long term outcome of the patient.

The group includes the following disorders:

- Pantothenate kinase-associated neurodegeneration (PKAN) also known as neurodegeneration with brain iron accumulation 1 (NBIA1) and Hallervorden–Spatz syndrome

- PLAN (PLA2G6-associated neurodegeneration)

- MPAN (Mitochondrial membrane protein-associated neurodegeneration)

- BPAN (Beta-propeller protein-associated neurodegeneration)

- FAHN (Fatty acid hydroxylase-associated neurodegeneration)

- Kufor–Rakeb syndrome

- Neuroferritinopathy

- Aceruloplasminemia

- Woodhouse–Sakati syndrome

- CoPAN (CoA synthase protein-associated neurodegeneration)

- Idiopathic NBIA

- Neurodegeneration with brain iron accumulation 2B (NBIA2B)

- Neurodegeneration with brain iron accumulation 3 (NBIA3)

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.

A cure does not exist for I-Cell disease/Mucolipidosis II disease. Treatment is limited to controlling or reducing the symptoms that are associated with this disorder. Nutritional supplements, particularly iron and vitamin B12, are often recommended for individuals with I-Cell disease. Physical therapy to improve motor delays and speech therapy to improve language acquisition are treatment options. Surgery can remove the thin layer of corneal clouding to temporarily improve the complication. It is possible that bone marrow transplant may be helpful in delaying or correcting the neurological deterioration that occurs with I-Cell disease.. Even though there is no existing treatment, the Yash Gandhi Foundation is a 501(c)(3) non-profit organization focused on funding research for I-Cell disease

There is no specific treatment to this disorder. However, several symptoms may be alleviated. For instance, anemia is treated by iron supplements. Some of the movement deficiencies may be corrected with orthopedic intervention. The corneal clouding can be, at least, temporarily corrected by corneal transplantation.

"See the equivalent section in the main mucolipidosis article.

There is no current cure for superficial siderosis, only treatments to help alleviate the current symptoms and to help prevent the development of further symptoms. If a source of bleeding can be identified (sources are frequently not found), then surgical correction of the bleeding source can be performed; this has proved to be effective in halting the development of further symptoms in some cases and has no effect on symptoms that have already presented.

Patients with superficial siderosis are often treated with deferiprone, a lipid-soluble iron chelator, as this medication has been demonstrated to chelate iron in the central nervous system.

While on this drug you will need a frequent blood test (weekly) to keep an eye on the blood levels as this drug is known to lower certain blood levels such as the neutrophils and WBC (white blood count) and etc. While it is ok if these levels go low in the average person, if they go low while taking Deferiprone Ferriprox it can cause life threatening infections that can result in death.

Alleviation of the most common symptom, hearing loss, has been varyingly successful through the use of cochlear implants. Most people do not notice a large improvement after successful implantation, which is most likely due to damage to the vestibulocochlear nerve (cranial nerve VIII) and not the cochlea itself. Some people fare far better, with a return to near normal hearing, but there is little ability to detect how well a person will respond to this treatment at this time.

Treatment for autosomal dominant porencephaly type I is based on the symptoms that an individual is experiencing - for example, treatment of seizures with anticonvulsants. It is particularly important for individuals with this disorder and hypertension to control their blood pressure, as they are at higher risk of stroke. Other stroke prevention treatments include avoiding anticoagulants, smoking, and situations that may lead to head trauma.

Currently there is no cure for these disorders. Medical care is directed at treating systemic conditions and improving the person's quality of life. Physical therapy and daily exercise may delay joint problems and improve the ability to move.

Changes to the diet will not prevent disease progression, but limiting milk, sugar, and dairy products has helped some individuals experiencing excessive mucus.

Surgery to remove tonsils and adenoids may improve breathing among affected individuals with obstructive airway disorders and sleep apnea. Sleep studies can assess airway status and the possible need for nighttime oxygen. Some patients may require surgical insertion of an endotrachial tube to aid breathing. Surgery can also correct hernias, help drain excessive cerebrospinal fluid from the brain, and free nerves and nerve roots compressed by skeletal and other abnormalities. Corneal transplants may improve vision among patients with significant corneal clouding.

Enzyme replacement therapy (ERT) are currently in use or are being tested. Enzyme replacement therapy has proven useful in reducing non-neurological symptoms and pain. Currently BioMarin Pharmaceutical produces enzyme replacement therapies for MPS type I and VI. Aldurazyme is an enzymatic replacement therapy for alpha-L-iduronidase produced by BioMarin for use in Type I MPS. In July 2006, the United States Food and Drug Administration approved a synthetic version of I2S produced by Shire Pharmaceuticals Group, called Elaprase, as a treatment for MPS type II (Hunter syndrome).

Bone marrow transplantation (BMT) and umbilical cord blood transplantation (UCBT) have had limited success in treating the mucopolysaccharidoses. Abnormal physical characteristics, except for those affecting the skeleton and eyes, may be improved, but neurologic outcomes have varied. BMT and UCBT are high-risk procedures and are usually performed only after family members receive extensive evaluation and counseling.

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.

No treatment modality has been unequivocally demonstrated to reduce the complications of alkaptonuria. Main treatment attempts have focused on preventing ochronosis through the reduction of accumulating homogentisic acid. Such commonly recommended treatments include large doses of ascorbic acid (vitamin C) or dietary restriction of amino acids phenylalanine and tyrosine. However, vitamin C treatment has not shown to be effective, and protein restriction (which can be difficult to adhere to) has not shown to be effective in clinical studies.

Several recent studies have suggested that the herbicide nitisinone may be effective in the treatment of alkaptonuria. Nitisinone inhibits the enzyme, 4-hydroxyphenylpyruvate dioxygenase, responsible for converting tyrosine to homogentisic acid, thereby blocking the production and accumulation of HGA. Nitisinone has been used for some time at much higher doses in the treatment of type I tyrosinemia. Nitisinone treatment has been shown to cause a larger than 95% reduction in plasma and urinary HGA. The main drawback is accumulation of tyrosine, the long-term risks of which are unknown; there is a particular concern about damage to the cornea of the eye. Long-term use would require frequent monitoring for complications.

New potential treatment options being researched are Venesection (removing red blood cells), Iron chelation with deferiprone, and Coenzyme Q10 (ubiquinone).

There is no standard course of treatment for chorea. Treatment depends on the type of chorea and the associated disease. Although there are many drugs that can control it, no cure has yet been identified.

Vestronidase alfa-vjbk (Mepsevii) is the only drug approved by U.S. Food and Drug Administration for the treatment of pediatric and adult patients.

For those with type-I and most type-III, enzyme replacement treatment with intravenous recombinant glucocerebrosidase can decrease liver and spleen size, reduce skeletal abnormalities, and reverse other manifestations. This treatment costs about US$200,000 annually for a single person and should be continued for life. The rarity of the disease means dose-finding studies have been difficult to conduct, so controversy remains over the optimal dose and dosing frequency. Due to the low incidence, this has become an orphan drug in many countries, meaning a government recognizes and accommodates the financial constraints that limit research into drugs that address a small population.

The first drug for Gaucher's was alglucerase (Ceredase), which was a version of glucocerebrosidase that was harvested from human placental tissue and then modified with enzymes. It was approved by the FDA in 1991 and has been withdrawn from the market due to the approval of similar drugs made with recombinant DNA technology instead of being harvested from tissue; drugs made recombinantly are preferable, since there is no concern about diseases being transmitted from the tissue used in harvesting, there are fewer risks of variations in enzyme structure from batch to batch, and they are less expensive to manufacture.

Available recombinant glucocerebrosidases are:

- Imiglucerase (approved in 1995)

- Velaglucerase (approved in 2010)

- Taliglucerase alfa (Elelyso) (approved in 2012)

- Eliglustat (Cerdelga) (approved in 2014)

Miglustat is a small molecule, orally available drug that was first approved for Gaucher's Disease in Europe in 2002. It works by preventing the formation of glucocerebroside, the substance that builds up and causes harm in Gaucher's. This approach is called substrate reduction therapy.

There is no standard course of treatment for cerebellar hypoplasia. Treatment depends upon the underlying disorder and the severity of symptoms. Generally, treatment is symptomatic and supportive. Balance rehabilitation techniques may benefit those experiencing difficulty with balance. Treatment is based on the underlying disorder and the symptom severity. Therapies include physical, occuptational, speech/language, visual, psych/ behavioral meds, special education.

Neurodegeneration with brain iron accumulation (NBIA) is a group of inherited neurological disorders in which iron accumulates in the basal ganglia, resulting in progressive dystonia, Parkinsonism, spasticity, optic atrophy or retinal degeneration and neuropsychiatric abnormalities. NBIA disorders have been associated with genes in synapse and lipid metabolism related pathways. Describes a group of disorders characterized by an accumulation of brain iron and the presence of axonal spheroids in the central nervous system. Iron accumulation can occur any where in the brain, with accumulation typically occurring in globus pallidus, substantia nigra, pars reticula, striatum and cerebellar dentate nuclei. Symptoms can include various movement disorders, seizures, visual disturbances, and cognitive decline, usually in combination. The known causes of NBIA disorders are mutations in genes directly involved in iron metabolism, impaired phospholipid and ceramide metabolism, lysosomal disorders, as well as mutations in genes with unknown functions. Onset can occur at different ages, from early childhood to late adulthood. Magnetic resonance imaging (MRI) is used to distinguish between the different forms of NBIA due to the accumulation of iron in different areas of the brain. Patients typically fall into two different categories: (1) early onset, rapid progression or (2) late onset, slow progression. The first type is considered to be the classic presentation, while the second type is the atypical presentation. Phenotypes of the different disorders appear to be dependent on age, i.e. amount of iron accumulation and cognitive ability.

Children of affected individuals are obligate carriers for aceruloplasminemia. If the CP mutations has been identified in a related individual, prenatal testing is recommended. Siblings of those affected by the disease are at a 25% of aceruloplasminemia. In asymptomatic siblings, serum concentrations of hemoglobin and hemoglobin A1c should be monitored.

To prevent the progression of symptoms of the disease, annual glucose tolerance tests beginning in early teen years to evaluate the onset of diabetes mellitus. Those at risk should avoid taking iron supplements.

Jansky–Bielschowsky disease is an extremely rare autosomal recessive genetic disorder that is part of the neuronal ceroid lipofuscinosis (NCL) family of neurodegenerative disorders. It is caused by the accumulation of lipopigments in the body due to a deficiency in tripeptidyl peptidase I as a result of a mutation in the TPP1 gene. Symptoms appear between ages 2 and 4 and consist of typical neurodegenerative complications: loss of muscle function (ataxia), drug resistant seizures (epilepsy), apraxia, development of muscle twitches (myoclonus), and vision impairment. This late-infantile form of the disease progresses rapidly once symptoms are onset and ends in death between age 8 and teens. The prevalence of Jansky–Bielschowsky disease is unknown, however NCL collectively affects an estimated 1 in 100,000 individuals worldwide. Jansky–Bielschowsky disease is also known as: late-infantile Batten disease, LINCL, or neuronal ceroid lipofuscinosis.
