Treatment for MSS is symptomatic and supportive including physical and occupational therapy, speech therapy, and special education. Cataracts must be removed when vision is impaired, generally in the first decade of life. Hormone replacement therapy is needed if hypogonadism is present.

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.

There is no known cure to BVVL however a Dutch group have reported the first promising attempt at treatment of the disorder with high doses of riboflavin. This Riboflavin protocol seems to be beneficial in almost all cases. Specialist medical advice is of course essential to ensure the protocol is understood and followed correctly.

Patients will almost certainly require additional symptomatic treatment and supportive care. This must be specifically customized to the needs of the individual but could include mobility aids, hearing aids or cochlear implants, vision aids, gastrostomy feeding and assisted ventilation, while steroids may or may not help patients.

The first report of BVVL syndrome in Japanese literature was of a woman that had BVVL and showed improvement after such treatments. The patient was a sixty-year-old woman who had symptoms such as sensorineural deafness, weakness, and atrophy since she was 15 years old. Around the age of 49 the patient was officially diagnosed with BVVL, incubated, and then attached to a respirator to improve her CO2 narcosis. After the treatments, the patient still required respiratory assistance during sleep; however, the patient no longer needed assistance by a respirator during the daytime.

Most patients suffering from KTS have epilepsy that is resistant to anti-epileptic agents. Some patients showed a partial response to treatment, but very few were able to stop their epilepsy through treatment. One case was responsive to treatment using Phenobartbital and vigabatrin which are both anti-epileptic agents. Spasticity can be treated with baclofen, but not all patients are responsive to the treatment.

There is no known cure to DSMA1, and care is primarily supportive. Patients require respiratory support which may include non-invasive ventilation or tracheal intubation. The child may also undergo additional immunisations and offered antibiotics to prevent respiratory infections. Maintaining a healthy weight is also important. Patients are at risk of undernutrition and weight loss because of the increased energy spent for breathing. Physical and occupational therapy for the child can be very effective in maintaining muscle strength.

There is no published practice standard for the care in DSMA1, even though the Spinal Muscular Atrophy Standard of Care Committee has been trying to come to a consensus on the care standards for DSMA1 patients. The discrepancies in the practitioners’ knowledge, family resources, and differences in patient’s culture and/or residency have played a part in the outcome of the patient.

There does not yet exist a specific treatment for IP. Treatment can only address the individual symptoms.

Congenital dSMA has a relatively stable disease course, with disability mainly attributed to increased contractures rather than loss of muscle strength. Individuals frequently use crutches, knee, ankle, and/or foot orthoses, or wheelchairs. Orthopaedic surgery can be an option for some patients with severely impaired movement. Physical therapy and occupational therapy can help prevent further contractures from occurring, though they do not reverse the effects of preexisting ones. Some literature suggests the use of electrical stimulation or botulinum toxin to halt the progression of contractures.

In terms of a cure there is currently none available, however for the disease to manifest itself, it requires mutant gene expression. Manipulating the use of protein homoestasis regulators can be therapuetic agents, or a treatment to try and correct an altered function that makes up the pathology is one current idea put forth by Bushart, et al. There is some evidence that for SCA1 and two other polyQ disorders that the pathology can be reversed after the disease is underway. There is no effective treatments that could alter the progression of this disease, therefore care is given, like occupational and physical therapy for gait dysfunction and speech therapy.

In terms of the management of spinal and bulbar muscular atrophy, no cure is known and treatment is supportive. Rehabilitation to slow muscle weakness can prove positive, though the prognosis indicates some individuals will require the use of a wheelchair in later stages of life.

Surgery may achieve correction of the spine, and early surgical intervention should be done in cases where prolonged survival is expected. Preferred nonsurgical treatment occurs due to the high rate of repeated dislocation of the hip.

Treatment is supportive.

- The aplastic anemia and immunodeficiency can be treated by bone marrow transplantation.

- Supportive treatment for gastrointestinal complications and infections.

- Genetic counselling.

Nusinersen (trade name: Spinraza) is the only approved drug to treat spinal muscular atrophy. It is a 2’-O-methoxyethyl, phosphorothioate modified antisense oligonucleotide targeting intronic splicing silencer N1 which is administered directly to the central nervous system using an intrathecal injection. Developed by Ionis Pharmaceuticals and licensed to Biogen, nusinersen was approved by FDA in December 2016, becoming the first approved pharmacological treatment for SMA. It was approved by the European Commission in centralised procedure in June 2017.

The clinical management of an individual with SMA varies based upon the severity/type. Management of individual patients with the same type of SMA can vary. The most severe form(type 0/I), individuals have the greatest muscle weakness requiring prompt intervention. Whereas the least severe form(type 4/adult onset), individuals may not seek the certain aspects of care until later(decades) in life. While types of SMA and individuals among each type may differ, therefore specific aspects of an individual’s care can differ.

No treatment is available for most of these disorders. Mannose supplementation relieves the symptoms in PMI-CDG (CDG-Ib) for the most part, even though the hepatic fibrosis may persist. Fucose supplementation has had a partial effect on some SLC35C1-CDG (CDG-IIc or LAD-II) patients.

RG2833, a histone deacetylase inhibitor developed by Repligen, was acquired by BioMarin Pharmaceutical in January 2014. The first human trials with this compound began in 2012.

Horizon Pharma's development plan of interferon gamma-1B for treatment of FA was given fast track designation by the Food and Drug Administration in 2015.

In its trials released in December 2016, however, the results showed no improvements over placebo in patients.

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.

Nicotinamide administration on patients was associated with a sustained improvement in frataxin concentrations towards those seen in asymptomatic carriers during 8 weeks of daily dosing. The daily oral administration of 3.8 g nicotinamide resulted in a 1.5-times increase, whereas 7.5 g resulted in a doubling of frataxin protein concentration.

The treatment of arthrogryposis includes occupational therapy, physical therapy, splinting and surgery. The primary long-term goals of these treatments are increasing joint mobility, muscle strength and the development of adaptive use patterns that allow for walking and independence with activities of daily living. Since arthrogryposis includes many different types, the treatment varies between patients depending on the symptoms.

Only a few good articles exist in which a surgical technique that is used to treat arthrogryposis is described. These surgeries are explained below.

In terms of treatment for neuromuscular diseases (NMD), "exercise" might be a way of managing them, as NMD individuals would gain muscle strength. In a study aimed at results of exercise, in muscular dystrophy and Charcot-Marie-Tooth disease, the later benefited while the former did not show benefit; therefore, it depends on the disease Other management routes for NMD should be based on medicinal and surgical procedures, again depending on the underlying cause.

Since December 2016, autosomal recessive proximal spinal muscular atrophy can be treated with nusinersen. No cure is known to any of the remaining disorders of the spinal muscular atrophies group. The main objective there is to improve quality of life which can be measured using specific questionnaires. Supportive therapies are widely employed for patients who often also require comprehensive medical care involving multiple disciplines, including pulmonology, neurology, orthopedic surgery, critical care, and clinical nutrition. Various forms of physiotherapy and occupational therapy are frequently able to slow down the pace of nerve degeneration and muscle wasting. Patients also benefit greatly from the use of assistive technology.

There is no known cure for MSA and management is primarily supportive.

Ongoing care from a neurologist specializing in "movement disorders" is recommended as the complex symptoms of MSA are often not familiar to less-specialized health care professionals.

One particularly serious problem, the drop in blood pressure upon standing up (with risk of fainting and thus injury from falling) often responds to fludrocortisone, a synthetic mineralocorticoid. Another common drug treatment is midodrine (an alpha-agonist). Non-drug treatments include "head-up tilt" (elevating the head of the whole bed by about 10 degrees), salt tablets or increasing salt in the diet, generous intake of fluids, and pressure (elastic) stockings. Avoidance of triggers of low blood pressure (such as hot weather, alcohol, and dehydration) are crucial.

Hospice/homecare services can be very useful as disability progresses.

Levodopa (L-Dopa), a drug used in the treatment of Parkinson's disease, improves parkinsonian symptoms in a small percentage of MSA patients. A recent trial reported that only 1.5% of MSA patients experienced a less than 50% improvement when taking levodopa, and even this was a transient effect lasting less than one year. Poor response to L-Dopa has been suggested as a possible element in the differential diagnosis of MSA from Parkinson's disease.

A November, 2008 study conducted in Europe failed to find an effect for the drug riluzole in treating MSA or PSP.

People with AMC look their worst at birth. AMC is considered non-progressive, so with proper medical treatment, things can improve. The joint contractures that are present will not get worse than they are at the time of birth. There is no way to completely resolve or cure AMC. But with proper treatment, most children make significant improvements in their range of motion and ability to move their limbs which enables them to do activities of daily life, and live relatively normal lives. Therapeutic interventions that are cornerstone in the treatment of AMC include: stretching and range of motion exercises, physical, occupational, and speech therapy, splinting and serial casting. Surgical intervention may also improve joint mobility and function. Other positive prognostic factors for independent walking were active hips and knees, hip flexion contractures of less than 20 degrees and knee flexion contractures less than 15 degrees without severe scoliosis.

There is no permanent cure for this syndrome, although patients can be treated according to their specific symptoms. The prognosis for those with Cockayne syndrome is poor, as death typically occurs by the age of 12. Treatment usually involves physical therapy and minor surgeries to the affected organs, like cataract removal. Also wearing high-factor sunscreen and protective clothing is recommended as patients with Cockayne syndrome are very sensitive to UV radiation. Optimal nutrition can also help. Genetic counseling for the parents is recommended, as the disorder has a 25% chance of being passed to any future children, and prenatal testing is also a possibility. Another important aspect is prevention of recurrence of CS in other sibling. Identification of gene defects involved makes it possible to offer genetic counseling and antenatal

diagnostic testing to the parents who already have one affected child.

Management by rehabilitation professionals (physiatrists, physiotherapists, occupational therapists, speech therapists, and others) for problems with walking/movement, daily tasks, and speech problems is essential.

Physiotherapy can help to maintain the patient’s mobility and will help to prevent contractures. Instructing patients in gait training will help to improve their mobility and decrease their risk of falls. A physiotherapist may also prescribe mobility aids such as a cane or a walker to increase the patient’s safety. Other ways a physiotherapist can help to improve the patient’s safety are to teach them to move and transfer from sitting to standing slowly to decrease risk of falls and limit the effect of postural hypotension. Instruction in ankle pumping helps to return blood in the legs to the systemic circulation. To further control the postural hypotension, raising the head of the bed by 8 in (20.3 cm) while sleeping may be indicated as well as the use of elastic compression garments.

Speech and language therapists may assist in assessing, treating and supporting speech (dysarthria) and swallowing difficulties (dysphagia). Early intervention of swallowing difficulties is particularly useful to allow for discussion around tube feeding further in the disease progression.{doubtful - citation needed} At some point in the progression of the disease, fluid and food modification may be suggested. Speech changes mean that alternative communication may be needed, for example communication aids or word charts.

Social workers and occupational therapists can also help with coping with disability through the provision of equipment and home adaptations, services for caregivers and access to healthcare services, both for the person with MSA as well as family caregivers.

Although no specific treatment exists, the disease can be managed with anticonvulsants, physiotherapy, etc.

There is no cure for MMA. Treatment consists of muscle strengthening exercises and training in hand coordination. It has been proposed that the changes in this disease are from compression of the spinal cord in flexion due to forward shifting of the posterior dural sac. There have been treatments studies ranging from use of a cervical collar to anterior cervical fusion and posterior decompression.
