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).

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.

A painkiller available in several European countries, Flupirtine, has been suggested to possibly slow down the progress of NCL, particularly in the juvenile and late infantile forms. No trial has been officially supported in this venue, however. Currently the drug is available to NCL families either from Germany, Duke University Medical Center in Durham, North Carolina, and the Hospital for Sick Children in Toronto, Ontario.

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.

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.

While there is no cure for HPS, treatment for chronic hemorrhages associated with the disorder includes therapy with vitamin E and the antidiuretic dDAVP.

Treatment is limited. Drugs can alleviate the symptoms, such as sleep difficulties and epilepsy. Physiotherapy helps affected children retain the ability to remain upright for as long as possible, and prevents some of the pain.

Recent attempts to treat INCL with cystagon have been unsuccessful.

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.

Currently, no cure for Zellweger syndrome is known, nor is a course of treatment made standard. Infections should be guarded against to prevent such complications as pneumonia and respiratory distress. Other treatment is symptomatic and supportive. Patients usually do not survive beyond one year of age.

Current available treatment is limited to treating the symptoms, not the cause. Seizure frequency can be regulated by the use of drugs such as Clonazepam (or other benzodiazepines) and Sodium Valproate. Clonazepam functions by increasing GABA activity at the GABA receptor. GABA is an inhibitory neurotransmitter and therefore, its increased activity hyperpolarizes cells. Clonazepam has been effective in minimising seizure activity, especially during puberty. Sodium valproate prevents the depolarization of the cell by blocking sodium ion channels and inhibitory GABA enzymes. Both of these anticonvulsants lead to depression of the central nervous system.

Valproic acid is the first line drug choice for reducing generalised seizures and myoclonus. Levetiracetam is also effective for both generalised seizures and myoclonus. Clonazepam and high-dose piracetam can alleviate myoclonus. Phenytoin can worsen seizures and may speed up neurodegeneration; carbamazepine, oxcarbazepine, tiagabine, vigabatrin, gabapentin and pregabalin may worsen myoclonus and myoclonic seizures. Other common medications to treat ULD include topiramate and zonisamide. If an individual with Unverricht–Lundborg disease is particularly sensitive to a certain type of stimulus, it is also beneficial to reduce the patient's exposure to that stimulus in order to reduce the likelihood of seizures. Since ULD is progressive and may not get better over time, depression has been documented in many cases, so providing a strong support group of friends, family, and even other individuals with ULD is very beneficial.

While there is no current cure to repair the mutated CSTB gene, several antiepileptic drugs are effective in reducing seizures and helping patients with ULD to manage the symptoms. In addition, new research is being performed to examine the effectiveness of other types of treatments.

Long term management is by use of anticonvulsant medication, principally valproate, stiripentol, topiramate or clobazam. Ketogenic diet has also been found useful in certain cases

Management of breakthrough seizures is by benzodiazepine such as midazolam.

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.

The malabsorption resulting from lack of bile acid has resulted in elemental formula being suggested, which are low in fat with < 3% of calories derived from long chain triglycerides (LCT). However, reduced very long chain fatty acids (VLCFA) has not been shown to reduce blood VLCFA levels , likely because humans can endogenously produce most VLCFA. Plasma VLCFA levels are decreased when dietary VLCFA is reduced in conjunction with supplementation of Lorenzo’s oil (a 4:1 mixture of glyceryl trioleate and glyceryl trierucate) in X-ALD patients . Since docosahexaenoic acid (DHA) synthesis is impaired [59], DHA supplementation was recommended, but a placebo-controlled study has since showed no clinical efficacy . Due to the defective bile acid synthesis, fat soluble supplements of vitamins, A, D, E, and K are recommended.

A preoperative pulmonology consultation is needed. The anesthesia team should

be aware that patients may have postoperative pulmonary complications as part

of the syndrome.

Preoperative hematology consultation is advisable prior to elective ocular

surgeries. Since patients with the syndrome have bleeding tendencies,

intraoperative, perioperative, and postoperative hemorrhages should be

prevented and treated. If platelet aggregation improves with desmopressin, it

may be administered in the preoperative period. However, sometimes

plasmapheresis is needed in the perioperative period.

Ophthalmologists should try to avoid retrobulbar blocks in patients with the

syndrome. Whenever possible, patients with HPS may benefit from general

endotracheal anesthesia. Phacoemulsification may help prevent intraoperative

and postoperative bleeding in patients with the syndrome. Prolonged bleeding

has been reported following strabismus surgery in patients with the syndrome.

Life expectancy is only moderately affected by NE because the rate of disease progression is slow. Patients usually survive past 40-50 years of age.

Neonatal seizures are often controlled with phenobarbital administration. Recurrent seizures later in life are treated in the standard ways (covered in the main epilepsy article). Depending on the severity, some infants are sent home with heart and oxygen monitors that are hooked to the child with stick on electrodes to signal any seizure activity. Once a month the monitor readings are downloaded into a central location for the doctor to be able to read at a future date. This monitor is only kept as a safeguard as usually the medication wards off any seizures. Once the child is weaned off the phenobarbital, the monitor is no longer necessary.

Currently, the most common form of treatment for SLOS involves dietary cholesterol supplementation. Anecdotal reports indicate that this has some benefits; it may result in increased growth, lower irritability, improved sociability, less self-injurious behaviour, less tactile defensiveness, fewer infections, more muscle tone, less photosensitivity and fewer autistic behaviours. Cholesterol supplementation begins at a dose of 40–50 mg/kg/day, increasing as needed. It is administered either through consuming foods high in cholesterol (eggs, cream, liver), or as purified food grade cholesterol. Younger children and infants may require tube feeding. However, dietary cholesterol does not reduce the levels of 7DHC, cannot cross the blood–brain barrier, and does not appear to improve developmental outcomes. One empirical study found that cholesterol supplementation did not improve developmental delay, regardless of the age at which it began. This is likely because most developmental delays stem from malformations of the brain, which dietary cholesterol cannot ameliorate due to its inability to cross the blood–brain barrier.

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.

HMG-CoA reductase inhibitors have been examined as treatment for SLOS. Given that this catalyzes the rate-limiting step in cholesterol synthesis, inhibiting it would reduce the buildup of toxic metabolites such as 7DHC. Simvastatin is a known inhibitor of HMG-CoA reductase, and most importantly is able to cross the blood–brain barrier. It has been reported to decrease the levels of 7DHC, as well as increase the levels of cholesterol. The increased cholesterol levels are due to simvastatin's effect on the expression of different genes. Simvastatin increases the expression of "DHCR7", likely leading to increased activity of DHCR7. It has also been shown to increase the expression of other genes involved in cholesterol synthesis and uptake. However, these benefits are dependent on the amount of residual cholesterol synthesis. Because some individuals possess less severe mutations and demonstrate some amount of DCHR7 activity, these people benefit the most from simvastatin therapy as they still have a partially functioning enzyme. For individuals that show no residual DCHR7 activity, such as those homozygous for null alleles or mutations, simvastatin therapy may actually be toxic. This highlights the importance of identifying the specific genotype of the SLOS patient before administering treatment. It is still unknown if simvastatin will improve the behavioural or learning deficits in SLOS.

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.

CBPS is commonly treated with anticonvulsant therapy to reduce seizures. Therapies include anticonvulsant drugs, adrenocorticotropic hormone therapy, and surgical therapy, including focal corticectomy and callosotomy. Special education, speech therapy, and physical therapy are also used to help children with intellectual disability due to CBPS.

Treatment is symptomatic, and may include anti-seizure medication and special or supplemental education consisting of physical, occupational, and speech therapies.

Conservative treatment involves the long term use of laxatives and enemas, and has limited success. Dietary changes in order to control the disease are ineffective and high fiber diets often worsen the symptoms in children. As a last resort, surgical treatment (internal sphincter myectomy or colon resection) is used. In extreme cases, the only effective cure is a complete transplant of the affected parts.
