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.

Pharmaceutical management, as with Parkinson's disease, involves striking a balance between treating the motor, emotive, and cognitive symptoms. Motor symptoms appear to respond somewhat to the medications used to treat Parkinson's disease (e.g. levodopa), while cognitive issues may improve with medications for Alzheimer's disease such as donepezil. Medications used in the treatment of ADHD (e.g. methylphenidate) might improve cognition or daytime sleepiness; however, medications for both Parkinson's disease and ADHD increase levels of the chemical dopamine in the brain, so increase the risk of hallucinations with those classes of pharmaceuticals.

Treatment of the movement and cognitive portions of the disease may worsen hallucinations and psychosis, while treatment of hallucinations and psychosis with antipsychotics may worsen parkinsonian or ADHD symptoms in DLB, such as tremor or rigidity and lack of concentration or impulse control. Physicians may find the use of cholinesterase inhibitors represents the treatment of choice for cognitive problems and donepezil (Aricept), rivastigmine (Exelon), and galantamine (Reminyl) may be recommended as a means to help with these problems and to slow or prevent the decline of cognitive function. DLB may be more responsive to donepezil than Alzheimer's disease. Memantine also may be useful. Levocarb may help with movement problems, but in some cases, as with dopamine agonists, may tend to aggravate psychosis in people with DLB. Clonazepam may help with rapid eye movement behavior disorder; table salt or antihypotensive medications may help with fainting and other problems associated with orthostatic hypotension. Botulinum toxin injections in the parotid glands may help with sialorrhea. Other medications, especially stimulants such as the ADHD drug methylphenidate (Ritalin) and modafinil, may improve daytime alertness, but as with the antiparkinsonian drug Levocarb, antihyperkinetics such as Ritalin increase the risk of psychosis. Experts advise extreme caution in the use of antipsychotic medication in people with DLB because of their sensitivity to these agents. When these medications must be used, atypical antipsychotics are preferred to typical antipsychotics; a very low dose should be tried initially and increased slowly, and patients should be carefully monitored for adverse reactions to the medications.

Due to hypersensitivity to neuroleptics, preventing DLB patients from taking these medications is important. People with DLB are at risk for neuroleptic malignant syndrome, a life-threatening illness, because of their sensitivity to these medications, especially the older typical antipsychotics, such as haloperidol. Other medications, including medications for urinary incontinence and the antihistamine medication diphenhydramine (Benadryl), also may worsen confusion.

Because the exact cause of CBD is unknown, there exists no formal treatment for the disease. Instead, treatments focus on minimizing the appearance or effect of the symptoms resulting from CBD. The most easily treatable symptom of CBD is parkinsonism, and the most common form of treatment for this symptom is the application of dopaminergic drugs. However, in general only moderate improvement is seen and the relief from the symptom is not long-lasting. In addition, palliative therapies, including the implementation of wheelchairs, speech therapy, and feeding techniques, are often used to alleviate many of the symptoms that show no improvement with drug administration.

No cure for dementia with Lewy bodies is known. Treatment may offer symptomatic benefit, but remains palliative in nature. Current treatment modalities are divided into pharmaceutical and caregiving.

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.

No medications have been shown to prevent or cure dementia. Medications may be used to treat the behavioural and cognitive symptoms but have no effect on the underlying disease process.

Acetylcholinesterase inhibitors, such as donepezil, may be useful for Alzheimer disease and dementia in Parkinson's, DLB, or vascular dementia. The quality of the evidence however is poor and the benefit is small. No difference has been shown between the agents in this family. In a minority of people side effects include a slow heart rate and fainting.

As assessment for an underlying cause of the behavior is a needed before prescribing antipsychotic medication for symptoms of dementia. Antipsychotic drugs should be used to treat dementia only if non-drug therapies have not worked, and the person's actions threaten themselves or others. Aggressive behavior changes are sometimes the result of other solvable problems, that could make treatment with antipsychotics unnecessary. Because people with dementia can be aggressive, resistant to their treatment, and otherwise disruptive, sometimes antipsychotic drugs are considered as a therapy in response. These drugs have risky adverse effects, including increasing the patient's chance of stroke and death. Generally, stopping antipsychotics for people with dementia does not cause problems, even in those who have been on them a long time.

N-methyl-D-aspartate (NMDA) receptor blockers such as memantine may be of benefit but the evidence is less conclusive than for AChEIs. Due to their differing mechanisms of action memantine and acetylcholinesterase inhibitors can be used in combination however the benefit is slight.

While depression is frequently associated with dementia, selective serotonin reuptake inhibitors (SSRIs) do not appear to affect outcomes.

The use of medications to alleviate sleep disturbances that people with dementia often experience has not been well researched, even for medications that are commonly prescribed. In 2012 the American Geriatrics Society recommended that benzodiazepines such as diazepam, and non-benzodiazepine hypnotics, be avoided for people with dementia due to the risks of increased cognitive impairment and falls. Additionally, there is little evidence for the effectiveness of benzodiazepines in this population. There is no clear evidence that melatonin or ramelteon improves sleep for people with dementia due to Alzheimer's disease. There is limited evidence that a low dose of trazodone may improve sleep, however more research is needed.

There is no solid evidence that folate or vitamin B12 improves outcomes in those with cognitive problems. Statins also have no benefit in dementia. Medications for other health conditions may need to be managed differently for a person who also has a diagnosis of dementia. The MATCH-D criteria can help identify ways that a diagnosis of dementia changes medication management for other health conditions. It is unclear if there is a link between blood pressure medication and dementia. There is a possibility that people may experience an increase in cardiovascular-related events if these medications are withdrawn.

Management Corticosteroids may be effective in some patients. Additional treatment options are beta-interferon or immunosuppressive therapy. Otherwise management is supportive and includes physiotherapy, occupational therapy and nutritional support in the later stages as patients lose their ability to eat.

Aromatherapy and massage have unclear evidence. There have been studies on the efficacy and safety of cannabinoids in relieving behavioral and psychological symptoms of dementia.

Omega-3 fatty acid supplements from plants or fish sources do not appear to benefit or harm people with mild to moderate Alzheimer's disease. It is unclear if taking omega-3 fatty acid supplements can improve other types of dementia.

There is currently no cure or standard procedure for treatment. A bone marrow transplant has been attempted on a child, but it made no improvement. Hydrocephalus may be seen in younger patients and can be relieved with surgery or by implanting a shunt to relieve pressure.

As of 2010, there was no cure for MMND. People with MMND are given supportive care to help them cope, which can include physical therapy, occupational therapy, counselling, and hearing aids.

Treatment of ALS2-related disorders includes physical therapy and occupational therapy to promote mobility and independence and use of computer technologies and devices to facilitate writing and voice communication.

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.

Currently, there is no cure for FTD. Treatments are available to manage the behavioral symptoms. Disinhibition and compulsive behaviors can be controlled by selective serotonin reuptake inhibitors (SSRIs). Although Alzheimer's and FTD share certain symptoms, they cannot be treated with the same pharmacological agents because the cholinergic systems are not affected in FTD.

Because FTD often occurs in younger people (i.e. in their 40's or 50's), it can severely affect families. Patients often still have children living in the home. Financially, it can be devastating as the disease strikes at the time of life that often includes the top wage-earning years.

Personality changes in individuals with FTD are involuntary. Managing the disease is unique to each individual, as different patients with FTD will display different symptoms, sometimes of rebellious nature.

Research has focused on finding a pharmacological treatment that is specific for intention tremor. Limited success has been seen in treating intention tremor with drugs effective at treating essential tremor. Clinical trials of levetiracetam, typically used to treat epilepsy, and pramipexole, used to treat resting tremor, were completed in 2009-2010 to establish their effectiveness in treating kinetic tremor. A clinical trial for riluzole, typically used to treat amyotrophic lateral sclerosis, was completed at the Sapienza University of Rome to evaluate its effectiveness of treating cerebellar ataxia and kinetic tremor.

Since pseudobulbar palsy is a syndrome associated with other diseases, treating the underlying disease may eventually reduce the symptoms of pseudobulbar palsy.

Possible pharmacological interventions for pseudobulbar affect include the tricyclic antidepressants, serotonin reuptake inhibitors, and a novel approach utilizing dextromethorphan and quinidine sulfate. Nuedexta is an FDA approved medication for pseudobulbar affect. Dextromethorphan, an N-methyl-D-aspartate receptor antagonist, inhibits glutamatergic transmission in the regions of the brainstem and cerebellum, which are hypothesized to be involved in pseudobulbar symptoms, and acts as a sigma ligand, binding to the sigma-1 receptors that mediate the emotional motor expression.

Currently, treatment for FTDP-17 is only symptomatic and supportive.

It is very difficult to treat an intention tremor. The tremor may disappear for a while after a treatment has been administered and then return. This situation is addressed with a different treatment. First, individuals will be asked if they use any of the drugs known to cause tremors. If so, they are asked to stop taking the medication and then evaluated after some time to determine if the medication was related to the onset of the tremor. If the tremor persists, treatment that follows may include drug therapy, lifestyle changes, and more invasive forms of treatment, such as surgery and thalamic deep brain stimulation.

Intention tremors are known to be very difficult to treat with pharmacotherapy and drugs. Although there is no established pharmacological treatment for an intention tremor, several drugs have been found to have positive effects on intention tremors and are used as treatment by many health professionals. Isoniazid, buspirone hydrochloride, glutethimide, carbamazepine, clonazepam, topiramate, zofran, propranolol and primidone have all seen moderate results in treating intention tremor and can be prescribed treatments. Isoniazid inhibits γ-aminobutyric acid-aminotransferase, which the first step in enzymatic breakdown of GABA, thus increasing GABA, the major inhibitory neurotransmitter in the central nervous system. This causes a reduction in cerebellar ataxias. Another neurotransmitter targeted by drugs that has been found to alleviate intention tremors is serotonin. The agonist buspirone hydrochloride, which decreases serotonin's function in the central nervous system, has been viewed as an effective treatment of intention tremors.

Physical therapy has had great results in reducing tremors but usually does not cure them. Relaxation techniques, such as meditation, yoga, hypnosis, and biofeedback, have seen some results with tremors. Wearing wrist weights which weigh down one's hands as they make movements, masking much of the tremor, is a proven home remedy. This is not a treatment, since wearing the weights does not have any lasting effects when they are not on. However, they do help the individual cope with the tremor immediately.

A more radical treatment that is used in individuals who do not respond to drug therapy, physical therapy, or any other treatment listed above, with moderate to severe intention tremors, is surgical intervention. Deep brain stimulation and surgical lesioning of the thalamic nuclei has been found to be an effective long-term treatment with intention tremors.

Deep brain stimulation treats intention tremors but does not help related diseases or disorders such as dyssynergia and dysmetria. Deep brain stimulation involves the implantation of a device called a neurostimulator, sometimes called a 'brain pacemaker'. It sends electrical impulses to specific parts of the brain, changing brain activity in a controlled manner. In the case of an intention tremor, the thalamic nuclei is the region targeted for treatment. This form of treatment causes reversible changes and does not cause any permanent lesions. Since it is reversible, deep brain stimulation is considered fairly safe: Reduction in tremor amplitude is almost guaranteed and sometimes resolved. Some individuals with multiple sclerosis have seen sustained benefits in MS progress.

Thalamotomy is another surgical treatment where lesions of the thalamus nucleus are created to disrupt the tremor circuit. Thalamotomy has been used to treat many forms of tremors, including those that arise from trauma, multiple sclerosis, stroke, and those whose cause it unknown. This is a very invasive, high-risk treatment with many negative effects, such as multiple sclerosis worsening, cognitive dysfunction, worsening of dysarthria, and dysphagia. Immediate positive effects are seen in individuals treated with a thalamotomy procedure. However, the tremor often comes back; it is not a complete treatment. Thalamotomy is in clinical trials to determine the validity of the treatment of intention tremors with all its high risks.

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.

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.

In the US, neuroborreliosis is typically treated with intravenous antibiotics which cross the blood–brain barrier, such as penicillins, ceftriaxone, or cefotaxime. One relatively small randomized controlled trial suggested ceftriaxone was more effective than penicillin in the treatment of neuroborreliosis. Small observational studies suggest ceftriaxone is also effective in children. The recommended duration of treatment is 14 to 28 days.

Several studies from Europe have suggested oral doxycycline is equally as effective as intravenous ceftriaxone in treating neuroborreliosis. Doxycycline has not been widely studied as a treatment in the US, but antibiotic sensitivities of prevailing European and US isolates of "Borrelia burgdorferi" tend to be identical. However, doxycycline is generally not prescribed to children due to the risk of bone and tooth damage.

Discreditied or doubtful treatments for neuroborreliosis include:

- Malariotherapy

- Hyperbaric oxygen therapy

- Colloidal silver

- Injections of hydrogen peroxide and bismacine

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.

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.

Symptoms of frontotemporal dementia progress at a rapid, steady rate. Patients suffering from the disease can survive between 2–15 years. Eventually patients will need 24-hour care for daily function.

CSF leaks are a known cause of reversible frontotemporal dementia.

Corticobasal degeneration (CBD) or corticobasal ganglionic degeneration (CBGD) is a rare, progressive neurodegenerative disease involving the cerebral cortex and the basal ganglia. CBD symptoms typically begin in people from 50–70 years of age, and the average disease duration is six years. It is characterized by marked disorders in movement and cognitive dysfunction, and is classified as one of the Parkinson plus syndromes. Clinical diagnosis is difficult, as symptoms of CBD are often similar to those of other disorders, such as Parkinson's disease (PD), progressive supranuclear palsy (PSP), and dementia with Lewy bodies (DLB). Due to the various clinical presentations associated with CBD, a final diagnosis can only be made upon neuropathologic examination.
