No specific treatment is known that would prevent, slow, or reverse HSP. Available therapies mainly consist of symptomatic medical management and promoting physical and emotional well-being. Therapeutics offered to HSP patients include:

- Baclofen – a voluntary muscle relaxant to relax muscles and reduce tone. This can be administered orally or intrathecally. (Studies in HSP )

- Tizanidine – to treat nocturnal or intermittent spasms (studies available )

- Diazepam and clonazepam – to decrease intensity of spasms

- Oxybutynin chloride – an involuntary muscle relaxant and spasmolytic agent, used to reduce spasticity of the bladder in patients with bladder control problems

- Tolterodine tartate – an involuntary muscle relaxant and spasmolytic agent, used to reduce spasticity of the bladder in patients with bladder control problems

- Botulinum toxin – to reduce muscle overactivity (existing studies for HSP patients)

- Antidepressants (such as selective serotonin re-uptake inhibitors, tricyclic antidepressants and monoamine oxidase inhibitors) – for patients experiencing clinical depression

- Physical therapy – to restore and maintain the ability to move; to reduce muscle tone; to maintain or improve range of motion and mobility; to increase strength and coordination; to prevent complications, such as frozen joints, contractures, or bedsores.

Physical therapy is the predominant treatment of symptoms. Orthopedic shoes and foot surgery can be used to manage foot problems.

Although HSP is a progressive condition, the prognosis for individuals with HSP varies greatly. It primarily affects the legs although there can be some upperbody involvement in some individuals. Some cases are seriously disabling while others are less disabling and are compatible with a productive and full life. The majority of individuals with HSP have a normal life expectancy.

Genetic counseling is an important tool for preventing new cases if this is wished by at-risk family members. Appropriate genetic counseling is based on an accurate diagnosis. Therefore, clinicians and genetic counselors should use ulcero-mutilating complications as the main diagnostic criteria. Since the disease is inherited as an autosomal dominant trait, there is a Mendelian risk of 50% for subsequent generations regardless of their sex. Prenatal testing for pregnancies at increased risk is possible if the disease-causing mutation has been identified in the family. Predictive testing is useful for young people to avoid serious complications of the disease.

Patients can often live with PLS for many years and very often outlive their neurological disease and succumb to some unrelated condition. There is currently no effective cure, and the progression of symptoms varies. Some people may retain the ability to walk without assistance, but others eventually require wheelchairs, canes, or other assistive devices.

Treatment for individuals with PLS is symptomatic. Baclofen and tizanidine may reduce spasticity. Quinine or phenytoin may decrease cramps. Some patients who do not receive adequate relief from oral treatment may consider intrathecal baclofen (i.e., infusion of medication directly into the cerebrospinal fluid via a surgically placed continuous infusion pump). However, patients are carefully selected for this type of procedure to ensure that they will likely benefit from this invasive procedure.

Physical therapy often helps prevent joint immobility. Speech therapy may be useful for those with involvement of the facial muscles. Physiotherapy treatment focuses on reducing muscle tone, maintaining or improving range of motion, increasing strength and coordination, and improving functional mobility. In PLS, stretching is thought to improve flexibility and can also reduce muscle spasticity and cramps.

Patients with PLS may find it beneficial to have an evaluation, as well as follow-up visits at multidisciplinary clinics, similar to those available for people with ALS. These multidisciplinary clinics may provide patients with the necessary treatment that they require by having an occupational therapist, physical therapist, speech language pathologist, dietician and nutritionist, all in one site.

Gene-based therapies for patients with HSAN I are not available to date, hence supportive care is the only treatment available for the patients. Ulcero-mutilating complications are the most serious, prominent, and leading diagnostic features in HSAN I. Since the complications mimic foot ulcers caused by diabetic neuropathy, the treatment for foot ulcers and infections can follow the guidelines given for diabetic foot care which starts with early and accurate counseling of patients about risk factors for developing foot ulcerations. Orthopedic care and the use of well fitting shoes without pressure points should also be included. Recently, the treatment of the foot complications has reached an efficient level allowing treatment on an outpatient basis. Early treatment of the foot complications often avoids hospitalization and, in particular, amputations. In sum, the principles of the treatment are removal of pressure to the ulcers, eradication of infection, and specific protective footwear afterwards.

There is no cure for PMD, nor is there a standard course of treatment. Treatment, which is symptomatic and supportive, may include medication for seizures and spasticity. Regular evaluations by physical medicine and rehabilitation, orthopedic, developmental and neurologic specialists should be made to ensure optimal therapy and educational resources. The prognosis for those with Pelizaeus–Merzbacher disease is highly variable, with children with the most severe form (so-called connatal) usually not surviving to adolescence, but survival into the sixth or even seventh decades is possible, especially with attentive care. Genetic counseling should be provided to the family of a child with PMD.

In December 2008, StemCells Inc., a biotech company in Palo Alto, received clearance from the U.S. Food and Drug Administration (FDA) to conduct Phase I clinical trials in PMD to assess the safety of transplanting human neural stem cells as a potential treatment for PMD. The trial was initiated in November 2009 at the University of California, San Francisco (UCSF) Children's Hospital.

Autosomal Recessive Spastic Ataxia of the Charlevoix-Saguenay (ARSACS) is a very rare neurodegenerative genetic disorder that primarily affects people from the Saguenay–Lac-Saint-Jean and Charlevoix regions of Quebec or descendants of native settlers in this region. This disorder has also been demonstrated in people from various other countries including India, Turkey, Japan, The Netherlands, Italy, Belgium, France and Spain. The prevalence has been estimated at about 1 in 1900 in Quebec, but it is very rare elsewhere.

Individuals with paraplegia can range in their level of disability, requiring treatments to vary from case to case. From a rehabilitation standpoint, the most important factor is to gain as much functionality and independence back as possible. Physiotherapists spend many hours within a rehabilitation setting working on strength, range of motion/stretching and transfer skills. Wheelchair mobility is also an important skill to learn. Most paraplegics will be dependent on a wheelchair as a mode of transportation. Thus it is extremely important to teach them the basic skills to gain their independence. Activities of daily living (ADLs) can be quite challenging at first for those with a spinal cord injury (SCI). With the aid of physiotherapists and occupational therapists, individuals with an SCI can learn new skills and adapt previous ones to maximize independence, often living independently within the community.

As a matter of everyday maintenance, muscle stretching, range of motion exercises, yoga, contact improvisation, modern dance, resistance training, and other physical activity regimens are often utilized by those with spastic CP to help prevent contractures and reduce the severity of symptoms.

Major clinical treatments for spastic diplegia are:

- Baclofen (and its derivatives), a gamma amino butyric acid (GABA) substitute in oral (pill-based) or intrathecal form. Baclofen is essentially chemically identical to the GABA that the damaged, over-firing nerves cannot absorb, except that it has an extra chemical 'marker' on it that makes the damaged nerves 'think' it is a different compound, and thus those nerves will absorb it. Baclofen is noted for being the sole medication available for GABA-deficiency-based spasticity which acts on the actual cause of the spasticity rather than simply reducing symptomatology as muscle relaxants and painkillers do. The intrathecal solution is a liquid injected into the spinal fluid for trial, and if successful in reducing spasticity, thereafter administered via an intrathecal pump, which has variously been proven potentially very dangerous on one or another level with long-term use (see article), including sudden and potentially lethal baclofen overdose, whereas the oral route, which comes in 10- or 20-milligram tablets and the dosage of which can be gently titrated either upward or downward, as well as safely ceased entirely, has not.

- Antispasmodic muscle relaxant chemicals such as tizanidine and botulinum toxin (Botox), injected directly into the spastic muscles; Botox wears off every three months.

- Phenol and similar chemical 'nerve deadeners', injected selectively into the over-firing nerves in the legs on the muscle end to reduce spasticity in their corresponding muscles by preventing the spasticity signals from reaching the legs; Phenol wears off every six months.

- Orthopedic surgery to release the spastic muscles from their hypertonic state, a usually temporary result because the spasticity source is the nerves, not the muscles; spasticity can fully reassert itself as little as one year post-surgery.

- Selective dorsal rhizotomy, a neurosurgery directly targeting and eliminating ("cutting" or "lesioning") the over-firing nerve rootlets and leaving the properly firing ones intact, thereby permanently eliminating the spasticity but compelling the person to spend months re-strengthening muscles that will have been severely weakened by the loss of the spasticity, due to the fact of those muscles not really having had actual strength to begin with.

The inheritance pattern is autosomal recessive. The disorder is caused by a mutation in the SGCG on chromosome 13. The mutation of the SACS gene causes the production of an unstable, poorly functioning SACSIN protein. It is unclear as to how this mutation affects the central nervous system (CNS) and skeletal muscles presenting in the signs and symptoms of ARSACS.

Distal hereditary motor neuropathy type V (dHMN V) is a particular type of neuropathic disorder. In general, distal hereditary motor neuropathies affect the axons of distal motor neurons and are characterized by progressive weakness and atrophy of muscles of the extremities. It is common for them to be called "spinal forms of Charcot-Marie-Tooth disease (CMT)", because the diseases are closely related in symptoms and genetic cause. The diagnostic difference in these diseases is the presence of sensory loss in the extremities. There are seven classifications of dHMNs, each defined by patterns of inheritance, age of onset, severity, and muscle groups involved. Type V (sometimes notated as Type 5) is a disorder characterized by autosomal dominance, weakness of the upper limbs that is progressive and symmetrical, and atrophy of the small muscles of the hands.

Olfactory ensheathing cells (OEC) have been transplanted with success into the spinal cord of Polish man named Darek Fidyka, who was the victim of a knife attack that left him paraplegic in 2010. In 2014, Fidyka underwent pioneering spinal surgery that used nerve grafts, from his ankle, to 'bridge the gap' in his severed spinal cord and OEC's to stimulate the spinal cord cells. The surgery was performed in Poland in collaboration with Prof Geoff Raisman, chair of neural regeneration at University College London's Institute of Neurology, and his research team. The olfactory cells were taken from the patients olfactory bulbs in his brain and then grown in the lab, these cells were then injected above and below the impaired spinal tissue. Fidyka regained sensory and motor function in his lower limbs, notably on the side of the transplanted OEC's. Fidyka first noticed the success three months after the procedure, when his left thigh started gaining muscle mass. MRIs suggest that the gap in his spinal cord has been closed up. He is believed to be the first person in the world to recover sensory function from a complete severing of the spinal nerves.

There is no known cure for cerebral palsy, however there is a large array of treatments proven effective at improving quality of life and relieving some of the symptoms associated with CP, especially SHCP. Some treatments are aimed at improving mobility, strengthening muscle and improving coordination. Although CP is due to permanent damage and is not progressive in nature, without treatment the symptoms can become worse, intensifying in pain and severity, and create complications that were not initially present. Some treatments are preventative measures to help prevent further complications, such as complete paralysis of the arm due to non-use and subsequent worsening hypertonia and joint contracture. Others forms of treatment are corrective in nature. Many treatments target symptoms that are indirectly related to or caused by the SHCP. Many of these treatments are common for other forms of CP as well. Treatment is individualized based on each case and the specific needs of the patient. Treatments are often combined with other forms of treatment and a long term treatment plan is created and continuously evaluated. Treatment can include the following:

- "Physical therapy" – Physical therapy is the most common form of treatment (source needed). It may include sensory stimulation, stretching, strengthening and positioning. Constraint-induced movement therapy is a newer form of physical therapy for SHCP that involves casting or splinting the unaffected arm to promote use of the affected arm (Taub). The theory behind constraint-induced movement therapy is that new neural pathways are created. Alternative forms of physical therapy include yoga and dance. Physical therapy may also include the use of braces while not actively involved with the therapist.

- "Occupational therapy" – Occupational therapy evaluates and treats patients through selected activities in order to enable people to function as effectively and independently as possible in daily life. Occupational therapy is geared toward the individual to achieve optimal results and performance while learning to cope with their disability.

- "Speech therapy" – Due to difficulties in speech, speech therapy is often necessary. Aside from helping with understanding language and increasing communication skills, speech therapists can also assist children that have difficulty eating and drinking.

- "Behavioral therapy" — Psychotherapy and counseling are heavily used in treatment of individuals with SHPD to help them cope emotionally with their needs and frustrations. Counseling through social work can be very beneficial for social issues and adjustments to society. Psychotherapy becomes a more important aspect of therapy when more serious issues such as depression become problematic. Play therapy is a common treatment for all young children with or without disabilities, but can be very useful helping children with SHCP. This therapy again is individualized geared to improve emotional and social development; reduce aggression; improve cooperation with others; assist a child in processing a traumatic event or prepare for an upcoming event such as surgery.

- "Surgery" – Although surgery may become necessary in some cases, physical therapy and the consistent use of braces can help mitigate the need for surgery. Surgical procedures are painful with long and difficult recoveries and do not cure the condition. Most common, is surgery that effectively lengthens the muscle. This type of surgery is usually performed on the legs, but can be performed on the arms as well. Surgeries also may be necessary to realign joints. Other, less popular surgical techniques try to reduce spasticity by severing selected overactive nerves that control muscles. This procedure, known as selective dorsal root rhizotomy, is still somewhat controversial, and is generally used only on the lower extremities of severe cases. Other experimental surgical techniques are also being investigated. The benefits of surgery can also be negated or reversed if the patient does not participate in physical therapy and braces (or casts) are not worn regularly.

- "Medicinal" – Medication targeting symptoms associated with spasticity is also a relatively new treatment that is utilized, but is still in the early stages of development. Drugs such as baclofen, benzodiazepines (e.g., diazepam), tizanidin, and sometimes dantrolene have shown promise in the effort to diminish spasticity. Botulinum toxin ("Botox") type A may reduce spasticity a few months at a time and has frequently been considered a beneficial treatment for children with SHCP and other forms of CP. Botox has been shown to be especially beneficial to reducing spasticity in the gastrocnemius (calf) muscle. This therapy can improve range of motion, reduce deformity, improve response to occupational and physical therapy, and delay the need for surgery. Botox injections have also shown advantages for upper extremities. There is still some doubt for the effectiveness, and some side effects to the relaxed muscles have been a loss of strength for patients with some muscle control. Casting, in conjunction with Botox injections may be an additional option for better results. Research is constantly investing in new improvements and more experimental therapy and treatment.

In most cases, between the age of 2 and 4 oculomotor signals are present. Between the age of 2 and 8, telangiectasias appears. Usually by the age of 10 the child needs a wheel chair. Individuals with autosomal recessive cerebellum ataxia usually survive till their 20s; in some cases individuals have survived till their 40s or 50s.

Upper limb paralysis refers to the loss of function of the elbow and hand. When upper limb function is absent as a result of a spinal cord injury it is a major barrier to regain autonomy. People with tetraplegia should be examined and informed concerning the options for reconstructive surgery of the tetraplegic arms and hands.

The long-term prognosis of Costeff syndrome is unknown, though it appears to have no effect on life expectancy at least up to the fourth decade of life. However, as mentioned previously, movement problems can often be severe enough to confine individuals to a wheelchair at an early age, and both visual acuity and spasticity tend to worsen over time.

Pelizaeus–Merzbacher disease (PMD) is a rare central nervous system disorder in which coordination, motor abilities, and intellectual function are delayed to variable extents.

The treatment of 2-Hydroxyglutaric aciduria is based on seizure control, the prognosis depends on how severe the condition is.

In the industrialized world, the incidence of overall cerebral palsy, which includes but is not limited to spastic diplegia, is about 2 per 1000 live births. Thus far, there is no known study recording the incidence of CP in the overall nonindustrialized world. Therefore, it is safe to assume that not all spastic CP individuals are known to science and medicine, especially in areas of the world where healthcare systems are less advanced. Many such individuals may simply live out their lives in their local communities without any medical or orthopedic oversight at all, or with extremely minimal such treatment, so that they are never able to be incorporated into any empirical data that orthopedic surgeons or neurosurgeons might seek to collect. It is shocking to note that—as with people with physical disability overall—some may even find themselves in situations of institutionalization, and thus barely see the outside world at all.

From what "is" known, the incidence of spastic diplegia is higher in males than in females; the Surveillance of Cerebral Palsy in Europe (SCPE), for example, reports a M:F ratio of 1.33:1. Variances in reported rates of incidence across different geographical areas in industrialized countries are thought to be caused primarily by discrepancies in the criteria used for inclusion and exclusion.

When such discrepancies are taken into account in comparing two or more registers of patients with cerebral palsy and also the extent to which children with mild cerebral palsy are included, the incidence rates still converge toward the average rate of 2:1000.

In the United States, approximately 10,000 infants and babies are born with CP each year, and 1200–1500 are diagnosed at preschool age when symptoms become more obvious. It is interesting to note that those with extremely mild spastic CP may not even be aware of their condition until much later in life: Internet chat forums have recorded men and women as old as 30 who were diagnosed only recently with their spastic CP.

Overall, advances in care of pregnant mothers and their babies has not resulted in a noticeable decrease in CP; in fact, because medical advances in areas related to the care of premature babies has resulted in a greater survival rate in recent years, it is actually "more" likely for infants with cerebral palsy to be born into the world now than it would have been in the past. Only the introduction of quality medical care to locations with less-than-adequate medical care has shown any decreases in the incidences of CP; the rest either have shown no change or have actually shown an increase. The incidence of CP increases with premature or very low-weight babies regardless of the quality of care.

Emery–Dreifuss muscular dystrophy is a condition that mainly affects muscles used for movement, such as skeletal muscles and also affects the cardiac muscle, it is named after Alan Eglin H. Emery and Fritz E. Dreifuss.

Autosomal recessive cerebellar ataxia type 1 (ARCA1) is a condition characterized by progressive problems with movement. Signs and symptoms of the disorder first appear in early to mid-adulthood. People with this condition initially experience impaired speech (dysarthria), problems with coordination and balance (ataxia), or both. They may also have difficulty with movements that involve judging distance or scale (dysmetria). Other features of ARCA1 include abnormal eye movements (nystagmus) and problems following the movements of objects with their eyes. The movement problems are slowly progressive, often resulting in the need for a cane, walker, or wheelchair.

Delayed diagnosis of cervical spine injury has grave consequences for the victim. About one in 20 cervical fractures are missed and about two-thirds of these patients have further spinal-cord damage as a result. About 30% of cases of delayed diagnosis of cervical spine injury develop permanent neurological deficits. In high-level cervical injuries, total paralysis from the neck can result. High-level tetraplegics (C4 and higher) will likely need constant care and assistance in activities of daily living, such as getting dressed, eating and bowel and bladder care. Low-level tetraplegics (C5 to C7) can often live independently.

Even with "complete" injuries, in some rare cases, through intensive rehabilitation, slight movement can be regained through "rewiring" neural connections, as in the case of the late actor Christopher Reeve.

In the case of cerebral palsy, which is caused by damage to the motor cortex either before, during (10%), or after birth, some people with tetraplegia are gradually able to learn to stand or walk through physical therapy.

Quadriplegics can improve muscle strength by performing resistance training at least three times per week. Combining resistance training with proper nutrition intake can greatly reduce co-morbidities such as obesity and type 2 diabetes.

There is currently no cure for Costeff syndrome. Treatment is supportive, and thus focuses on management of the symptoms. The resulting visual impairment, spasticity, and movement disorders are treated in the same way as similar cases occurring in the general population.
