Although there is no cure for NM, it is possible, and common for many people live healthy active lives even with moderate to severe cases. Research continues to seek ways to ameliorate debilitating symptoms and lengthen the life-span in quality ways for those affected. Some people have seen mild improvements in secretion handling, energy level, and physical functioning with supplemental L-tyrosine, an amino acid that is available through health centers. Some symptoms may worsen as the patient ages. Muscle loss increases with age naturally, but it is even more significant with nemaline myopathy.

At present, Nemaline myopathy does not have a cure. Nemaline myopathy is a very rare disease that only effects 1 out of 50,000 on average, although recent studies show that this number is even smaller. There are a number of treatments to minimize the symptoms of the disease. The treatments and procedures to help patients with nemaline myopathy vary depending on the severity of the disease. A possible accommodation could be the use of a stabilizer, such as a brace. Other means include moderate stretching and moderate exercise to help target muscles maintain maximum health.

As people with NM grow and develop throughout their lives, it is important for them to see a variety of health professionals regularly, including a neurologist, physical therapist, and others, such as speech therapists and psychologists, to help both the patient and family adjust to everyday life.

TCAs include imipramine, amitriptyline, desipramine, and nortriptyline. They are generally regarded as first or second-line treatment for DPN. Of the TCAs, imipramine has been the best studied. These medications are effective at decreasing painful symptoms but suffer from multiple side effects that are dose-dependent. One notable side effect is cardiac toxicity, which can lead to fatal abnormal heart rhythms. Additional common side effects include dry mouth, difficulty sleeping, and sedation. At low dosages used for neuropathy, toxicity is rare, but if symptoms warrant higher doses, complications are more common. Among the TCAs, amitriptyline is most widely used for this condition, but desipramine and nortriptyline have fewer side effects.

Typical opioid medications, such as oxycodone, appear to be no more effective than placebo. In contrast, low-quality evidence supports a moderate benefit from the use of atypical opioids (e.g., tramadol and tapentadol), which also have SNRI properties. Opioid medications are recommended as second or third-line treatment for DPN.

Because HFM is a rare disorder, there are no studies that define its optimal treatment. Correction of the systemic folate deficiency, with the normalization of folate blood levels, is easily achieved with high doses of oral folates or much smaller doses of parenteral folate. This will rapidly correct the anemia, immune deficiency and GI signs. The challenge is to achieve adequate treatment of the neurological component of HFM. It is essential that the folate dose is sufficiently high to achieve CSF folate levels as close as possible to the normal range for the age of the child. This requires close monitoring of the CSF folate level. The physiological folate is 5-methyltetrahydrofolate but the oral formulation available is insufficient for treatment of this disorder and a parenteral form is not available. The optimal folate at this time is 5-formyltetrahydrofolate which, after administration, is converted to 5-methyltetrahydrofolate. The racemic mixture of 5-formyltetrahydrofolate (leucovorin) is generally available; the active S-isomer, levoleucovorin, may be obtained as well. Parenteral administration is the optimal treatment if that is possible. Folic acid should not be used for the treatment of HFM. Folic acid is not a physiological folate. It binds tightly to, and may impede, FRα-mediated endocytosis which plays an important role in the transport of folates across the choroid plexus into the CSF (see above). For a further consideration of treatment see GeneReviews.

The importance of correctly recognizing progressive muscular atrophy as opposed to ALS is important for several reasons.

- 1) the prognosis is a little better. A recent study found the 5-year survival rate in PMA to be 33% (vs 20% in ALS) and the 10-year survival rate to be 12% (vs 6% in ALS).

- 2) Patients with PMA do not suffer from the cognitive change identified in certain groups of patients with MND.

- 3) Because PMA patients do not have UMN signs, they usually do not meet the "World Federation of Neurology El Escorial Research Criteria" for “Definite” or “Probable” ALS and so are ineligible to participate in the majority of clinical research trials such as drugs trials or brain scans.

- 4) Because of its rarity (even compared to ALS) and confusion about the condition, some insurance policies or local healthcare policies may not recognize PMA as being the life-changing illness that it is. In cases where being classified as being PMA rather than ALS is likely to restrict access to services, it may be preferable to be diagnosed as "slowly progressive ALS" or "lower motor neuron predominant" ALS.

An initial diagnosis of PMA could turn out to be slowly progressive ALS many years later, sometimes even decades after the initial diagnosis. The occurrence of upper motor neurone symptoms such as brisk reflexes, spasticity, or a Babinski sign would indicate a progression to ALS; the correct diagnosis is also occasionally made on autopsy.

Systemic (intravenous or oral) chemotherapy and intrathecal chemotherapy: Intrathecal therapy is when injection is done directly to the spinal cord into the sub-arachnoid space to avoid the Blood-Brain-Barrier (BBB) and gain direct access to the CSF. Intrathecal Therapy is preferred since intravenous chemotherapy do not penetrate the BBB. The most common chemicals used are liposomal cytarabine (DepoCyte) and intrathecal methotrexate (MTX).

In combination, intrathecal chemotherapy most often comprises methotrexate, cytarabine, thiotepa and steroids. Ventriculoperitoneal shunts may also be applied with chemotherapy to avoid invasive surgery to gain access to the CSF.

An example of treatment:

Intrathecal MTX injection at a dose of 15 mg/day for 5 days every other week with hydrocortisone acetate injecting IT on day one to prevent arachnoiditis, the inflammation of the arachnoid. MTX administration is continued until neurological progression or relapse occurred. Systemic chemotherapy, radiotherapy, and surgery are performed depending on the need of the patient.

Risks of treatments:

Both Chemotherapy and Radiotherapy are harmful to the body and most definitely the brain. Caution must be utilized in treating patients with NM. Another factor that makes treatment difficult is that there is no suitable method to evaluate the disease progression.

There is no standard treatment that has been established for NM thus treatments are almost always palliative.

Radiotherapy:

This method is used mostly for focal type of NM due to the nature of damage and success rate associated with the treatment. Radiotherapy targets and tumor and destroys the collective tissues of cancerous cells.

Progressive muscular atrophy (PMA), also known as Duchenne-Aran muscular atrophy and by various other names, is a rare subtype of motor neuron disease (MND) that affects only the lower motor neurons. PMA is thought to account for around 4% of all MND cases. This is in contrast to amyotrophic lateral sclerosis (ALS), the most common form of MND, which affects both the upper and lower motor neurones, or primary lateral sclerosis, another rare MND variant, which affects only the upper motor neurons. The distinction is important because PMA is associated with a better prognosis than classic ALS.

Treatment is predominantly preventive. Avoidance of topical phenols and diets low in tyrosine may help. Replacement and repair of damaged tissue is also possible.

Most patients with thin basement membrane disease need only reassurance. Indeed, this disease was previously referred to as "benign familial hematuria" because of its usually benign course. Angiotensin converting enzyme inhibitors have been suggested to reduce the episodes of hematuria, though controlled studies are lacking. Treating co-existing hypercalciuria and hyperuricosuria will also be helpful in reducing hematuria.

The molecular basis for thin basement membrane disease has yet to be elucidated fully; however, defects in the gene encoding the a4 chain of type IV collagen have been reported in some families.

Some patients and researchers have successfully treated solar urticaria with Omalizumab (trade name Xolair) which is commonly used to treat Idiopathic Urticaria. Omalizumab is a recombinant humanized monoclonal antibody against IgE. It acts by binding free IgE at the same site that IgE would bind to its high-affinity receptor (FcεRI) on mast cells, thereby reducing free IgE in the serum

Doctors will sometimes prescribe immunosuppressive drugs such as prednisolone and ciclosporin if the patient is suffering from an intense form of solar urticaria. However, the side effects of these medicines can be severe which is why they are reserved for the most extreme of cases.

Primary prophylaxis with low-molecular weight heparin, heparin, or warfarin is often considered in known familial cases. Anticoagulant prophylaxis is given to all who develop a venous clot regardless of underlying cause.

Studies have demonstrated an increased risk of recurrent venous thromboembolic events in patients with protein C deficiency. Therefore, long-term anticoagulation therapy with warfarin may be considered in these patients.

Homozygous protein C defect constitutes a potentially life-threatening disease, and warrants the use of supplemental protein C concentrates.

Liver transplant may be considered curative for homozygous protein C deficiency.

The following may provide relief:

- Cold compresses

- Pad and bandage with antibiotics drops for 24 hours, heals most of the cases

- anaesthetic drops should not be used

- Oral analgesics if pain is intolerable

- Single dose of tranquilizers

Several drugs are used off label by patients with EPP:

- Ursodeoxycholic acid is a bile acid that is administered to promote biliary secretion of protoporphyrin. Results of its use in EPP are controversial. However, it is known to alter the composition of bile, to protect hepatocytes from the cytotoxic effect of hydrophobic bile acids, and to stimulate biliary secretion by several distinct mechanisms.

- Hematin appears to reduce excess protoporphyrin production in the bone marrow. It has been administered to patients with EPP (3–4 mg/kg iv) who develop a crisis after liver transplantation.

- Plasmapheresis can also decrease the levels of protoporphyrin in plasma, however its use in treating acute episodes is controversial.

- Cholestyramine is an orally administered resin which reduces circulating levels of protoporphyrin by binding to protoporphyrin in the intestine and, hence, interrupting the enterohepatic circulation. It is usually used in combination with other treatment approaches.

- Activated charcoal, like cholestyramine, binds to protoporphyrin in the intestine and prevents its absorption. It is cheap and readily available. It seems to be effective in reducing circulating protoporphyrin levels.

Bone marrow transplantation, liver transplantation, acetylcysteine, extracorporeal albumin dialysis, parenteral iron and transfusion of erythrocytes are alternative plans for treatment of EEP.

As of 2015 there was no cure for CJD; some of the symptoms like twitching can be managed but otherwise treatment is palliative care.

The only approved medicine to treat EPP is afamelanotide, developed by Australian-based Clinuvel Pharmaceuticals and approved by the European Commission in December 2014 for treatment or prevention of phototoxicity in adult patients with EPP. It is marketed under the name Scenesse.

The discoloration usually disappears spontaneously over a period of several months after giving birth or stopping the oral contraceptives or hormone replacement therapy.

Treatments are often ineffective as it comes back with continued exposure to the sun. Assessment by a dermatologist will help guide treatment. This may include use of a Woods lamp to determine depth of the melasma pigment. Treatments to hasten the fading of the discolored patches include:

- Topical depigmenting agents, such as hydroquinone (HQ) either in over-the-counter (2%) or prescription (4%) strength. HQ is a chemical that inhibits tyrosinase, an enzyme involved in the production of melanin.

- Tretinoin, an acid that increases skin cell (keratinocyte) turnover. This treatment cannot be used during pregnancy.

- Azelaic acid (20%), thought to decrease the activity of melanocytes.

- Tranexamic acid by mouth has shown to provide rapid and sustained lightening in melasma by decreasing melanogenesis in epidermal melanocytes.

- Cysteamine hydrochloride (5%) over-the-counter. Mechanism of action seems to involve inhibition of melanin synthesis pathway

- Flutamide (1%)

- Chemical peels

- Microdermabrasion to dermabrasion (light to deep)

- Galvanic or ultrasound facials with a combination of a topical crème/gel. Either in an aesthetician's office or as a home massager unit.

- Laser but not IPL (IPL can make the melasma darker)

Evidence-based reviews found that the most effective therapy for melasma includes a combination on topical agents.

In all of these treatments the effects are gradual and a strict avoidance of sunlight is required. The use of broad-spectrum sunscreens with physical blockers, such as titanium dioxide and zinc dioxide is preferred over that with only chemical blockers. This is because UV-A, UV-B and visible lights are all capable of stimulating pigment production.

Patients should avoid other precipitants including hormonal triggers.

Cosmetic camouflage can also be used to hide melasma.

Treatment is directed towards the withdrawal of the offending agent, infusion of magnesium sulfate, antiarrhythmic drugs, and electrical therapy, such as a temporary pacemaker, as needed.

Because of the polymorphic nature of torsades de pointes, synchronized cardioversion may not be possible, and the patient may require an unsynchronized shock (or defibrillation).

Phototherapy is considered a second-line treatment for vitiligo. Exposing the skin to light from UVB lamps is the most common treatment for vitiligo. The treatments can be done at home with an UVB lamp or in a clinic. The exposure time is managed so that the skin does not suffer overexposure. Treatment can take a few weeks if the spots are on the neck and face and if they existed not more than 3 years. If the spots are on the hands and legs and have been there more than 3 years, it can take a few months. Phototherapy sessions are done 2–3 times a week. Spots on a large area of the body may require full body treatment in a clinic or hospital. UVB broadband and narrowband lamps can be used, but narrowband ultraviolet picked around 311 nm is the choice. It has been constitutively reported that a combination of UVB phototherapy with other topical treatments improves re-pigmentation. However, some vitiligo patients may not see any changes to skin or re-pigmentation occurring. A serious potential side effect involves the risk of developing skin cancer, the same risk as an over-exposure to natural sunlight.

Ultraviolet light (UVA) treatments are normally carried out in a hospital clinic. Psoralen and ultraviolet A light (PUVA) treatment involves taking a drug that increases the skin's sensitivity to ultraviolet light, then exposing the skin to high doses of UVA light. Treatment is required twice a week for 6–12 months or longer. Because of the high doses of UVA and psoralen, PUVA may cause side effects such as sunburn-type reactions or skin freckling.

Narrowband ultraviolet B (NBUVB) phototherapy lacks the side-effects caused by psoralens and is as effective as PUVA. As with PUVA, treatment is carried out twice weekly in a clinic or every day at home, and there is no need to use psoralen.

Topical preparations of immune suppressing medications including glucocorticoids (such as 0.05% clobetasol or 0.10% betamethasone) and calcineurin inhibitors (such as tacrolimus or pimecrolimus) are considered to be first-line vitiligo treatments.

Caffeine is the most widely used alerting drug in the world and has been shown to improve alertness in simulated night work. Caffeine and naps before a night shift reduces sleepiness during the shift. Modafinil and armodafinil are non-amphetamine alerting drugs originally developed for the treatment of narcolepsy that have been approved by the FDA (the US Food and Drug Administration) for excessive sleepiness associated with SWSD.

Phytophotodermatitis can be prevented by staying indoors after handling the above substances. However, the primary triggering mechanism is UV-A radiation (320–380 nm) which windows are not guaranteed to filter out.

Many different topical and oral medications can be used to treat the inflammatory reaction of phytophotodermatitis. A dermatologist may also prescribe a bleaching cream to help treat the hyperpigmentation and return the skin pigmentation back to normal. If they do not receive treatment, the affected sites may develop permanent hyperpigmentation or hypopigmentation.

As of June 2014 (the latest update on HFM in GeneReviews) a total of 32 families had been reported with a clinical diagnosis of HFM of which there was genotypic confirmation in 24 families. Since then, another two confirmed cases have been reported and an additional case was reported based on a clinical diagnosis alone. Most cases emerge from consanguineous parents with homozygous mutations. There are three instances of HFM from non-consanguineous parents in which there were heterozygous mutations. HFM cases are worldwide with mostly private mutations. However, a number of families of Puerto Rican ancestry have been reported with a common pathogenic variant at a splice receptor site resulting in the deletion of exon 3 and the absence of transport function. A subsequent population-based study of newborn infants in Puerto Rico identified the presence of the same variant on the island. Most of the pathogenic variants result in a complete loss of the PCFT protein or point mutations that result in the complete loss of function. However, residual function can be detected with some of the point mutants.
