Riluzole has been found to modestly prolong survival by approximately two to three months. It may have a greater survival benefit for those with a bulbar onset. It is approved by the US Food and Drug Administration (FDA) and recommended by the National Institute for Health and Care Excellence (NICE) (England and Wales). Riluzole does not reverse damage already done to motor neurons but affects neurons by reducing their activity through blocking Na+ entrance into the neurons and thus blocking the release of the chemicals that causes the activity of the motor neurons. The reduction in activity prevents the ruining of the neuronal muscle and so the drug can act as a protective chemical. Studies have shown that the function of this drug is dependent on the amount taken at a given time. The higher the concentration, the better the drug will protect the neurons from ruin. The recommended dosage of Riluzole is 50 mg, twice a day for people with known ALS for more than 5 years.

There are a number of side effects caused by the drug including the feeling of weakness in muscles but this is normal due to the function of the drug. Studies have shown that people on the drug are not likely to stop responding to it or develop symptoms that might cause the activity of neurons to rise again, making Riluzole an effective drug for prolonging survival.

In 2015, edaravone was approved in Japan for treatment of ALS after studying how and whether it works on 137 people with ALS and has obtained orphan drug status in the EU and USA. On May 5, 2017, the FDA approved edaravone to extend the survival period of people with ALS. It costs about 145,000 USD per year in the US and 35,000 USD per year in Japan.

Other medications may be used to help reduce fatigue, ease muscle cramps, control spasticity, and reduce excess saliva and phlegm. Drugs also are available to help people with pain, such as non-steroidal and anti-inflammatory drugs and opioids, depression, sleep disturbances, dysphagia, and constipation. Baclofen and diazepam are often prescribed to control the spasticity caused by ALS, and trihexyphenidyl, amitriptyline or most commonly glycopyrrolate may be prescribed when people with ALS begin having trouble swallowing their saliva. There is no evidence that medications are effective at reducing muscle cramps experienced by people with ALS.

Management of ALS attempts to relieve symptoms and extend life expectancy. This supportive care is best provided by multidisciplinary teams of healthcare professionals working with the person and their caregivers to keep them as mobile and comfortable as possible.

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.

The process of neurodegeneration is not well understood, so the diseases that stem from it have, as yet, no cures. In the search for effective treatments (as opposed to palliative care), investigators employ animal models of disease to test potential therapeutic agents. Model organisms provide an inexpensive and relatively quick means to perform two main functions: target identification and target validation. Together, these help show the value of any specific therapeutic strategies and drugs when attempting to ameliorate disease severity. An example is the drug Dimebon (Medivation). This drug is in phase III clinical trials for use in Alzheimer's disease, and also recently finished phase II clinical trials for use in Huntington's disease. In March 2010, the results of a clinical trial phase III were released; the investigational Alzheimer's disease drug Dimebon failed in the pivotal CONNECTION trial of patients with mild-to-moderate disease. With CONCERT, the remaining Pfizer and Medivation Phase III trial for Dimebon (latrepirdine) in Alzheimer's disease failed in 2012, effectively ending the development in this indication.

In another experiment using a rat model of Alzheimer's disease, it was demonstrated that systemic administration of hypothalamic proline-rich peptide (PRP)-1 offers neuroprotective effects and can prevent neurodegeneration in hippocampus amyloid-beta 25–35. This suggests that there could be therapeutic value to PRP-1.

Protein degradation offers therapeutic options both in preventing the synthesis and degradation of irregular proteins. There is also interest in upregulating autophagy to help clear protein aggregates implicated in neurodegeneration. Both of these options involve very complex pathways that we are only beginning to understand.

The goal of immunotherapy is to enhance aspects of the immune system. Both active and passive vaccinations have been proposed for Alzheimer's disease and other conditions, however more research must be done to prove safety and efficacy in humans.

Multifocal motor neuropathy is normally treated by receiving intravenous immunoglobulin (IVIG), which can in many cases be highly effective, or immunosuppressive therapy with cyclophosphamide or rituximab. Steroid treatment (prednisone) and plasmapheresis are no longer considered to be useful treatments; prednisone can exacerbate symptoms. IVIg is the primary treatment, with about 80% of patients responding, usually requiring regular infusions at intervals of 1 week to several months. Other treatments are considered in case of lack of response to IVIg, or sometimes because of the high cost of immunoglobulin. Subcutaneous immunoglobulin is under study as a less invasive, more-convenient alternative to IV delivery.

PBP is aggressive and relentless, and there were no treatments for the disease as of 2005. However, early detection of PBP is the optimal scenario in which doctors can map out a plan for management of the disease. This typically involves symptomatic treatments that are frequently used in many lower motor disorders.

Treatment is palliative, not curative (as of 2009).

Treatment options for lower limb weakness such as foot drop can be through the use of Ankle Foot Orthoses (AFOs) which can be designed or selected by an Orthotist based upon clinical need of the individual. Sometimes tuning of rigid AFOs can enhance knee stability.

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.

Because lack of sialic acid appears to be part of the pathology of IBM caused by GNE mutations, clinical trials with sialic acid supplements, and with a precursor of sialic acid, N-Acetylmannosamine, have been conducted, and as of 2016 further trials were planned.

The treatment for post-polio syndrome is generally palliative and consists of rest, analgesia (pain relief) and utilisation of mechanisms to make life easier such as powered wheelchairs. There are no reversive therapies. Fatigue is usually the most disabling symptom; energy conservation can significantly reduce fatigue episodes. Such conservation can be achieved with lifestyle changes, reducing workload and daytime sleeping. Weight loss is also recommended if patients are obese. In some cases, the use of lower limb orthotics can reduce energy usage.

Medications for fatigue, such as amantadine and pyridostigmine, have not been found to be effective in the management of PPS. Muscle strength and endurance training are more important in managing the symptoms of PPS than the ability to perform long aerobic activity. Management should focus on treatments such as hydrotherapy and developing other routines that encourage strength but do not affect fatigue levels. The recent trend is towards use of intravenous immunoglobulin (IVIG) which has yielded promising, albeit modest results, but there is insufficient evidence to recommend it as a treatment.

PPS increases the stress on the musculoskeletal system due to increasing muscular atrophy. A recent study showed that in a review of 539 PPS patients, 80 percent reported pain in muscles and joints and 87 percent had fatigue. Joint instability can cause significant pain in individuals with PPS and should be adequately treated with painkillers. Supervised activity programs and decreasing mechanical stress with braces and adaptive equipment are recommended.

Because PPS can fatigue facial muscles, as well as cause dysphagia (difficulty swallowing), dysarthria (difficulty speaking) or aphonia (inability to produce speech), persons with PPS may become malnourished due to difficulty eating. Compensatory routines can help relieve these symptoms such as eating smaller portions at a time and sitting down whilst eating. PPS with respiratory involvement requires special management such as breathing exercises, chest percussion with a stethoscope on regular occasions for observation of the disease and management of secretions. Failure to properly assess PPS with respiratory involvement can increase the risk of missing aspiration pneumonia (an infection of the lower respiratory tract) in an individual. Severe cases may require permanent ventilation or tracheostomy. Sleep apnoea may also occur. Other management strategies that may lead to improvement include smoking cessation, treatment of other respiratory diseases and vaccination against respiratory infections such as influenza.

There is no known cure for neuromyotonia, but the condition is treatable. Anticonvulsants, including phenytoin and carbamazepine, usually provide significant relief from the stiffness, muscle spasms, and pain associated with neuromyotonia. Plasma exchange and IVIg treatment may provide short-term relief for patients with some forms of the acquired disorder. It is speculated that the plasma exchange causes an interference with the function of the voltage-dependent potassium channels, one of the underlying issues of hyper-excitability in autoimmune neuromyotonia. Botox injections also provide short-term relief. Immunosuppressants such as Prednisone may provide long term relief for patients with some forms of the acquired disorder.

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.

Inadequate magnesium intake can cause fasciculations, especially after a magnesium loss due to severe diarrhea. Over-exertion and heavy alcohol consumption are also risk factors for magnesium loss. As 70–80% of the adult population does not consume the recommended daily amount of magnesium, inadequate intake may also be a common cause. Treatment consists of increased intake of magnesium from dietary sources such as nuts (especially almonds), bananas, and spinach. Magnesium supplements or pharmaceutical magnesium preparations may also be taken. However, too much magnesium may cause diarrhea, resulting in dehydration and nutrient loss (including magnesium itself, leading to a net loss, rather than a gain). It is well known as a laxative (Milk of Magnesia), though chelated magnesium can largely reduce this effect. Cheaper methods of the chelation process may be unsatisfactory for some people (e.g. mild diarrhea). Magnesium supplements recommend that they be taken only with meals, and not on an empty stomach.

Fasciculation also often occurs during a rest period after sustained stress, such as that brought on by unconsciously tense muscles. Reducing stress and anxiety is therefore another useful treatment.

There is no proven treatment for fasciculations in people with ALS. Among patients with ALS, fasciculation frequency is not associated with the duration of ALS and is independent of the degree of limb weakness and limb atrophy. No prediction of ALS disease duration can be made based on fasciculation frequency alone.

A motor neuron disease (MND) is any of several neurological disorders that selectively affect motor neurons, the cells that control voluntary muscles of the body. They include amyotrophic lateral sclerosis (ALS), hereditary spastic paraplegia (HSP), primary lateral sclerosis (PLS), progressive muscular atrophy (PMA), progressive bulbar palsy (PBP) and pseudobulbar palsy. Spinal muscular atrophies (SMA) are sometimes included in the group by some neurologists but it is different disease with clear genetic cause. They are neurodegenerative in nature and cause increasing disability and eventually, death.

Neurodegeneration is the progressive loss of structure or function of neurons, including death of neurons. Many neurodegenerative diseases – including amyotrophic lateral sclerosis, Parkinson's, Alzheimer's, and Huntington's – occur as a result of neurodegenerative processes. Such diseases are incurable, resulting in progressive degeneration and/or death of neuron cells. As research progresses, many similarities appear that relate these diseases to one another on a sub-cellular level. Discovering these similarities offers hope for therapeutic advances that could ameliorate many diseases simultaneously. There are many parallels between different neurodegenerative disorders including atypical protein assemblies as well as induced cell death. Neurodegeneration can be found in many different levels of neuronal circuitry ranging from molecular to systemic.

Some degree of control of the fasciculations may be achieved with the same medication used to treat essential tremor (beta-blockers and anti-seizure drugs). However, often the most effective approach to treatment is to treat any accompanying anxiety. No drugs, supplements, or other treatments have been found that completely control the symptoms. In cases where fasciculations are caused by magnesium deficiency, supplementing magnesium can be effective in reducing symptoms.

In many cases, the severity of BFS symptoms can be significantly reduced through a proactive approach to decrease the overall daily stress. Common ways to reduce stress include: exercising more, sleeping more, working less, meditation, and eliminating all forms of dietary caffeine (e.g. coffee, chocolate, cola, and certain over-the counter medications).

If pain or muscle aches are present alongside fasciculations, patients may be advised to take over-the-counter pain medications such as ibuprofen or acetaminophen during times of increased pain. Other forms of pain management may also be employed. Prior to taking any over-the-counter medications, individuals should initiate discussions with their health care provider(s) to avoid adverse effects associated with long-term usage or preexisting conditions.

In the United States, the term is often used to denote ALS, the most common disorder in the group. In the United Kingdom, the term is also spelled "motor neurone disease" (MND) and is sometimes used for the entire group; but mostly it refers to ALS.

While MND refers to a specific subset of similar diseases, there are numerous other diseases of motor neurons that are referred to collectively as "motor neuron disorders", for instance disease belonging to spinal muscular atrophies. However, they are not classified as "motor neuron diseases" by the tenth International Statistical Classification of Diseases and Related Health Problems (ICD-10), which is the definition followed in this article.

Currently there is no cure for dysmetria itself as it is actually a symptom of an underlying disorder. However, isoniazid and clonazepam have been used to treat dysmetria. Frenkel exercises treat dysmetria. There have also been numerous reported cases of chiropractic neurology as an effective holistic treatment for dysmetria. Cannabis has been used in trials in the U.K. and displayed some success, though it is not legal to use in some U.S. states.

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.

Frontotemporal lobar degeneration (FTLD) is a pathological process that occurs in frontotemporal dementia. It is characterized by atrophy in the frontal lobe and temporal lobe of the brain, with sparing of the parietal and occipital lobes.

Common proteinopathies that are found in FTLD include the accumulation of Tau proteins and TARDBPs. Mutations in the C9orf72 gene have been established as a major genetic contribution of FTLD, although defects in the GRN and MAPT genes are also associated with it.

Lytico-bodig disease, sometimes spelled Lytigo-bodig, is the name of a disease in the language of Chamorro. It is referred to by neuroscientists as amyotrophic lateral sclerosis-parkinsonism-dementia (ALS-PDC), a term coined by Asao Hirano and colleagues in 1961. It is a neurodegenerative disease of uncertain etiology that exists in the United States territory of Guam.

The disease resembles Amyotrophic Lateral Sclerosis (ALS), Parkinson's disease, and Alzheimer's. First reports of the disease surfaced in three death certificates on Guam in 1904. These death certificates made some mention of paralysis. The frequency of cases grew amongst the Chamorro people on Guam until it was the leading cause of adult death between 1945 and 1956. The incidence rate was 200 per 100,000 per year and it was 100 times more prevalent than in the rest of the world.

Neurologist Oliver Sacks detailed this disease in his book "The Island of the Colorblind"

. Sacks and Paul Alan Cox subsequently wrote that a local species of flying fox, which is now extinct due to overhunting, had been feeding on cycads and concentrating β-methylamino--alanine (BMAA), a known neurotoxin, in its body fat. The hypothesis suggests that consumption of the fruit bat by the Chamorro exposed them to BMAA, contributing to or causing their condition. Decline in consumption of the bats has been linked to a decline in the incidence of the disease.

As with bodig, the symptoms and forms of lytico present themselves differently from patient to patient.

Patient presentations include muscle atrophy, maxillofacial paralysis, inability to speak or swallow and subsequent choking. Some patients retain mental lucidity throughout the illness until death, much like ALS patients.

Diaphragm and respiratory accessory muscles can become paralyzed necessitating mechanical ventilation to facilitate breathing. Saliva must be suctioned from the mouth to prevent aspiration. This form of lytico-bodig is fatal in all cases.

Researchers now are testing different possibilities for treating dysmetria and ataxia. One opportunity for treatment is called rehearsal by eye movement. It is believed that visually guided movements require both lower- and higher-order visual functioning by first identifying a target location and then moving to acquire what is sought after. In one study, researchers used visually guided stepping which is parallel to visually guided arm movements to test this treatment. The patients suffered from saccadic dysmetria which in turn caused them to overshoot their movements 3. The patients first walked normally and were then told to twice review the area that was to be walked through 3. After rehearsal with eye movements, the patients improved their motor performance. Researchers believe that prior rehearsal with the eyes might be enough for a patient who suffers from motor dysmetria as a result of saccadic dysmetria to complete a motor task with enhanced spatial awareness.

Research has also been done for those patients who suffer from MS. Deep brain stimulation (DBS) remains a viable possibility for some MS patients though the long-term effects of this treatment are currently under review. The subjects who have undergone this treatment had no major relapse for six months and disabling motor function problems. Most subjects benefited from the implantation of the electrodes and some reported that their movement disorder was gone after surgery. However, these results are limiting at this time because of the small range of subjects who were used for the experiment and it is unknown whether this is a viable option for all MS patients who suffer from motor control problems.

Progressive bulbar palsy (PBP) is a medical condition. It belongs to a group of disorders known as motor neuron diseases. PBP is a disease that attacks the nerves supplying the bulbar muscles. These disorders are characterized by the degeneration of motor neurons in the cerebral cortex, spinal cord, brain stem, and pyramidal tracts. This specifically involves the glossopharyngeal nerve (IX), vagus nerve (X), and hypoglossal nerve (XII).

This disorder should not be confused with pseudobulbar palsy or progressive spinal muscular atrophy. The term Infantile progressive bulbar palsy is used to describe progressive bulbar palsy in children. Some neurologists consider this disorder to be a subset of amyotrophic lateral sclerosis (ALS), but others disagree with that classification.

Psychological interventions including psychotherapy, cognitive behavioural therapy (CBT), Biofeedback, and teaching self-hypnosis are also suggested to treat VCD. Intervention is generally targeted at making the client aware of stressors that may trigger VCD symptoms, to implement strategies to reduce stress and anxiety, and to teach techniques for coping with their symptoms.

CBT can focus on bringing awareness to negative thought patterns and help reframe them by focusing on problem solving strategies. Psychologists may also use relaxation to reduce distress when a patient is experiencing symptoms. Biofeedback can be a helpful addition to psychotherapy. The aim of Biofeedback is to educate the client on what happens to the vocal cords during breathing and to help them learn to control their symptoms.

Choosing an intervention strategy needs to be assessed by a multidisciplinary team and individualized therapy planned carefully, keeping the characteristics of each patient in mind.
