Before prescribing medication for these conditions which often resolve spontaneously, recommendations have pointed to improved skin hygiene, good hydration via fluids, good nutrition, and installation of padded bed rails with use of proper mattresses. Pharmacological treatments include the typical neuroleptic agents such as fluphenazine, pimozide, haloperidol and perphenazine which block dopamine receptors; these are the first line of treatment for hemiballismus. Quetiapine, sulpiride and olanzapine, the atypical neuroleptic agents, are less likely to yield drug-induced parkinsonism and tardive dyskinesia. Tetrabenazine works by depleting presynaptic dopamine and blocking postsynaptic dopamine receptors, while reserpine depletes the presynaptic catecholamine and serotonin stores; both of these drugs treat hemiballismus successfully but may cause depression, hypotension and parkinsonism. Sodium valproate and clonazepam have been successful in a limited number of cases. Stereotactic ventral intermediate thalamotomy and use of a thalamic stimulator have been shown to be effective in treating these conditions.

The medical treatment of essential tremor at the Movement Disorders Clinic at Baylor College of Medicine begins with minimizing stress and tremorgenic drugs along with recommending a restricted intake of beverages containing caffeine as a precaution, although caffeine has not been shown to significantly intensify the presentation of essential tremor. Alcohol amounting to a blood concentration of only 0.3% has been shown to reduce the amplitude of essential tremor in two-thirds of patients; for this reason it may be used as a prophylactic treatment before events during which one would be embarrassed by the tremor presenting itself. Using alcohol regularly and/or in excess to treat tremors is highly unadvisable, as there is a purported correlation between tremor and alcoholism. Alcohol is thought to stabilize neuronal membranes via potentiation of GABA receptor-mediated chloride influx. It has been demonstrated in essential tremor animal models that the food additive 1-octanol suppresses tremors induced by harmaline, and decreases the amplitude of essential tremor for about 90 minutes.

Two of the most valuable drug treatments for essential tremor are propranolol, a beta blocker, and primidone, an anticonvulsant. Propranolol is much more effective for hand tremor than head and voice tremor. Some beta-adrenergic blockers (beta blockers) are not lipid-soluble and therefore cannot cross the blood–brain barrier (propranolol being an exception), but can still act against tremors; this indicates that this drug’s mechanism of therapy may be influenced by peripheral beta-adrenergic receptors. Primidone’s mechanism of tremor prevention has been shown significantly in controlled clinical studies. The benzodiazepine drugs such as diazepam and barbiturates have been shown to reduce presentation of several types of tremor, including the essential variety. Controlled clinical trials of gabapentin yielded mixed results in efficacy against essential tremor while topiramate was shown to be effective in a larger double-blind controlled study, resulting in both lower Fahn-Tolosa-Marin tremor scale ratings and better function and disability as compared to placebo.

It has been shown in two double-blind controlled studies that injection of botulinum toxin into muscles used to produce oscillatory movements of essential tremors, such as forearm, wrist and finger flexors, may decrease the amplitude of hand tremor for approximately three months and that injections of the toxin may reduce essential tremor presenting in the head and voice. The toxin also may help tremor causing difficulty in writing, although properly adapted writing devices may be more efficient. Due to high incidence of side effects, use of botulinum toxin has only received a C level of support from the scientific community.

Deep brain stimulation toward the ventral intermediate nucleus of the thalamus and potentially the subthalamic nucleus and caudal zona incerta nucleus have been shown to reduce tremor in numerous studies. That toward the ventral intermediate nucleus of the thalamus has been shown to reduce contralateral and some ipsilateral tremor along with tremors of the cerebellar outflow, head, resting state and those related to hand tasks; however, the treatment has been shown to induce difficulty articulating thoughts (dysarthria), and loss of coordination and balance in long-term studies. Motor cortex stimulation is another option shown to be viable in numerous clinical trials.

Medications remain the basis of therapy in many cases. Symptomatic drug therapy is available for several forms of tremor:

- Parkinsonian tremor drug treatment involves L-DOPA and/or dopamine-like drugs such as pergolide, bromocriptine and ropinirole; They can be dangerous, however, as they may cause symptoms such as tardive dyskinesia, akathisia, clonus, and in rare instances tardive (late developing) psychosis. Other drugs used to lessen parkinsonian tremor include amantadine and anticholinergic drugs like benztropine

- Essential tremor may be treated with beta blockers (such as propranolol and nadolol) or primidone, an anticonvulsant

- Cerebellar tremor symptoms may decrease with the application of alcohol (ethanol) or benzodiazepine medications, both of which carry some risk of dependence and/or addiction

- Rubral tremor patients may receive some relief using L-DOPA or anticholinergic drugs. Surgery may be helpful

- Dystonic tremor may respond to diazepam, anticholinergic drugs, and intramuscular injections of botulinum toxin. Botulinum toxin is also prescribed to treat voice and head tremors and several movement disorders

- Primary orthostatic tremor sometimes is treated with a combination of diazepam and primidone. Gabapentin provides relief in some cases

- Enhanced physiological tremor is usually reversible once the cause is corrected. If symptomatic treatment is needed, beta blockers can be used

This condition is often treated with injections of botox, a commercially prepared form of botulinum toxin. Botox reduces the symptoms of the disorder but it is not a cure for dystonia. Since the root of the problem is neurological, doctors have explored sensorimotor retraining activities to enable the brain to "rewire" itself and eliminate dystonic movements. The work of several doctors such as Nancy Byl and Joaquin Farias has shown that sensorimotor retraining activities and proprioceptive stimulation can induce neuroplasticity, making it possible for patients to recover substantial function that was lost to focal dystonia.

Anticholinergics such as Artane can be prescribed for off-label use, as some sufferers have had success.

Bass guitarist and instructor Scott Devine said that he wears a glove while playing bass guitar because of the condition. He finds that the glove stops the involuntary finger movements. He says it works for him but does not suggest that it may work for everyone with the condition.

Eliminating tremor “triggers” such as caffeine and other stimulants from the diet is often recommended.

Essential tremor may benefit from slight doses of ethanol, but the potential negative consequences of regular ethanol intake need to be taken into account. Beta blockers have been used as an alternative to alcohol in sports such as competitive dart playing and carry less potential for addiction.

Physical therapy and occupational therapy may help to reduce tremor and improve coordination and muscle control for some patients. A physical therapist and/or occupational therapist will evaluate the patient for tremor positioning, muscle control, muscle strength, and functional skills. Teaching the patient to brace the affected limb during the tremor or to hold an affected arm close to the body is sometimes useful in gaining motion control. Coordination and balancing exercises may help some patients. Some occupational therapists recommend the use of weights, splints, other adaptive equipment, and special plates and utensils for eating.

When treating hemiballismus, it is first important to treat whatever may be causing the manifestation of this disorder. This could be hyperglycemia, infections, or neoplastic lesions. Some patients may not even need treatment because the disorder is not severe and can be self – limited.

Dopamine Blockers

When pharmacological treatment is necessary, the most standard type of drug to use is an antidopaminergic drug. Blocking dopamine is effective in about ninety percent of patients. Perphenazine, pimozide, haloperidol, and chlorpromazine are standard choices for treatment. Scientists are still unsure as to why this form of treatment works, as dopamine has not been directly linked to hemiballismus.

Anticonvulsants

An anticonvulsant called topiramate has helped patients in three cases and may be a viable treatment for the future.

ITB Therapy

Intrathecal baclofen (ITB) therapy is used to treat a variety of movement disorders such as cerebral palsy and multiple sclerosis. It can also be a possibility to help treat hemiballismus. In one case, before ITB the patient had an average of 10-12 ballism episodes of the right lower limb per hour. During episodes, the right hip would flex up to about 90 degrees, with a fully extended knee. After an ITB pump was implanted and the correct dosage was found, the frequency of ballistic right leg movements decreased to about three per day, and the right hip flexed to only 30 degrees. The patient was also able to better isolate individual distal joint movements in the right lower limb. The patient currently receives 202.4 microg/day of ITB and continues to benefit almost 6 years after the ITB pump was implanted.

Botulinum Injections

New uses for botulinum toxin have included treatment of hemiballismus. However, this is still in the early stages of testing. This treatment deals with the muscular manifestations of hemiballismus as opposed to the neurological causes.

Tetrabenazine

Tetrabenazine has been used to treat other movement disorders, but is now being used to treat hemiballismus. Patients using this medication have had a dramatic response. However, lowering the dosage leads to a return of symptoms. This drug works by depleting dopamine.

Antipsychotics

In one case, a patient had not been responding to haloperidol, thus the physician tried olanzapine. The patient made a significant recovery. More research is being performed on the use of these types of drugs in treating hemiballismus.

Functional Neurosurgery

Surgery as a treatment should only be used on patients with severe hemiballismus that has not responded to treatment. Lesioning of the globus pallidus or deep brain stimulation of the globus pallidus are procedures that can be used on humans. Usually, lesioning is favored over deep brain stimulation because of the maintenance required to continue stimulating the brain correctly and effectively.

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.

There are several different treatment approaches to dealing with athetosis. The most common methods are the use of drugs, surgical intervention, and retraining movements of the afflicted person. It is suggested that training a person to relearn movements can be helpful in select situations. Though, generally, this type of treatment will not work, in certain cases it can be found to be very helpful in treating the symptom of athetosis.

Drugs can also be used in the treatment of athetosis, however their collective effectiveness is not very convincing. There is not a single drug that is a standard among treatment. Many different medicines can be used, including:

- Artane

- Cogentin

- Curare, though not practical due to respiratory paralysis

- Tetrabenazine

- Haloperidol

- Thiopropazate

- Diazepam

Most instances of drug use where the symptoms seem to be lessened tend to be in more mild cases of athetosis.

Treatment by surgical intervention can obviously have the most immediate impact, again however, it is not a cure-all. In patients that have cerebral palsy as the cause of their athetosis, it has been demonstrated that a subthalamotomy tends to help relieve the extent of athetosis in approximately half of patients. Additionally, late 19th and early 20th century surgical accounts state that athetosis can be relieved by the removal of a part of the cerebral motor cortex or by cutting a part of the posterior spinal roots. Patients who undergo surgical treatment to relieve the athetosis often see significant improvement in the control of their limbs and digits. While surgery is often very beneficial in the short term and can produce near immediate results, in the long term it has been seen that its effects are not incredibly long lasting.

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.

PED patients usually avoid prolonged, continuous exertion to prevent occurrence of attacks. Use of anticonvulsants such as benzodiazepines show little to no success in PED patients. A few cases have shown that patients were able to lessen their attacks with a high carbohydrate snack. A new approach to managing PED is the ketogenic diet, which alters the primary cerebral energy metabolism from glucose to ketone bodies. Reports have shown that the ketonic diet protects against seizures in epilepsy. In PED, it is probable that ketones will provide sufficient energy for the basal ganglia, which is normally deficient in patients with PED.

Anticholinergic drugs are used to control neuroleptic-induced EPS, although akathisia may require beta blockers or even benzodiazepines. If the EPS are induced by an antipsychotic, EPS may be reduced by dose titration or by switching to an atypical antipsychotic, such as aripiprazole, ziprasidone, quetiapine, olanzapine, risperidone, or clozapine. These medications possess an additional mode of action that is believed to negate their effect on the nigrostriatal pathway, which means they are associated with fewer extrapyramidal side-effects than "conventional" antipsychotics (chlorpromazine, haloperidol, etc.), although some research has shown that second generation neuroleptics cause EPS at the same rate as the first generation drugs.

Commonly used medications for EPS are anticholinergic agents such as benztropine (Cogentin), diphenhydramine (Benadryl), and trihexyphenidyl (Artane). Another common course of treatment includes dopamine agonist agents such as pramipexole. These medications reverse the symptoms of extrapyramidal side effects caused by antipsychotics or other drugs that either directly or indirectly inhibit dopaminergic neurotransmission.

Studies are yet to be undertaken on the optimum dosage of the causative drugs to reduce their side effects (extrapyramidal symptoms (EPS)).

Almost all patients respond positively to antiepileptic (anticonvulsant) drugs. One of the drugs most often mentioned in the literature is carbamazepine, and is the most widely used drug for treating PKD. Other anticonvulsants like valproic acid, phenytoin and clonazepam are common alternatives. Other categories of drugs have also been used, such as dopamine affecting drugs like Levodopa or Tetrabenazine. Individuals with the disorder can also modify their behavior to lessen their attacks without the influence of drug therapy. For example, decreasing stress to avoid precipitants can help patients decrease the number of attacks. In addition, avoiding any sudden movements can also prevent an attack. In order to prevent an attack, some individuals use their auras as a warning, while others purposefully perform slow gestures or movements prior to a triggering movement. Many, if not most, individuals end up growing out of the attacks with age, even without medicinal therapy, but some patients will go back to having attacks after a period of remission. In regards to secondary PKD, treatment of the primary condition can lessen the PKD attacks in those individuals.

PKD patients usually show a good response to anticonvulsants. Most commonly used medications are sodium blockers, carbamazepine and phenytoin. During a drug-testing study, patients reported a decreasing response to the latter use of anticonvulsants and switched to carbamazepine or phenytoin. Refraining from established triggers such as sudden movement has been shown to lessen attacks occurrences. Avoidance of predisposing factors such as stress, excitement, and fatigue also help manage attacks.

Valbenazine has been approved by the FDA for tardive dyskinesia. Tetrabenazine, which is a dopamine depleting drug, is sometimes used to treat tardive dyskinesia and other movement disorders. However, it is only approved to treat chorea associated with Huntington's disease. The related VMAT2 inhibitor, reserpine, has also been tried in one small randomised double-blind placebo-controlled trial as a treatment for TD with success, as has α-methyldopa. Ondansetron has shown some benefit in experimental studies on tardive dyskinesia and a variety of anti-Parkinsonian medications are used such as donepezil, baclofen, and pramipexole. Clonidine may also be useful in the treatment of TD, although dose-limiting hypotension and sedation may hinder its usage. Botox injections are used for minor focal dystonia, but not in more advanced tardive dyskinesia. Benzodiazepines are an effective treatment for TD, however their use is limited by the development of tolerance which requires ever increasing doses of the benzodiazepines to be used to attenuate TD symptoms. The most popular benzodiazepine for the treatment of TD is clonazepam. Vitamin B6 has been reported to be an effective treatment for TD in two randomised double-blind placebo-controlled trials.

In males, the branched-chain amino acid formula Tarvil, containing the amino acids valine, isoleucine, and leucine in a 3:3:4 ratio was reported as beneficial for motor symptoms in a small, non-blinded study.

As athetosis is relatively difficult to treat, efforts are being made to help those with the condition live and perform tasks more effectively and more efficiently. One such example of work that has been recently undertaken is a project to help those affected with athetosis to use a computer with more ease. Software for the control of the computer uses joysticks that perform linear filtering to aid in control.

An additional possible treatment option for those afflicted with the symptom is neurostimulation. Studies have begun, and in cerebral palsy patients affected with dystonia-choreoathetosis, it has been demonstrated that neurostimulation has been an effective treatment in lessening symptoms in patients. There has not been a tremendous amount of experimentation, though, in this as a possible treatment option.

There is no standard course of treatment for chorea. Treatment depends on the type of chorea and the associated disease. Although there are many drugs that can control it, no cure has yet been identified.

There are two lines of treatment for Pisa syndrome. The first line entails discontinuation or reduction in dose of the antipsychotic drug(s). The second line of treatment is an anticholinergic medication. A pharmacological therapy for Pisa syndrome caused by prolonged use of antipsychotic drugs has not been established yet.

Medication is often not necessary in children as symptoms usually alleviate spontaneously as the child ages. However, because the disorder may affect wakeful behavior, many adults who continue to suffer from RMD may seek treatment. Benzodiazepines or tricyclic antidepressants have been considered as therapeutic options in managing the disorder. Infantile and adolescent RMD respond well to low doses of clonazepam. Prescription medications such as ropinirole or pramipexole given to restless legs syndrome patients do not show any clinical improvement in many patients with RMD.

PLMD is often treated with anti-Parkinson medication; it may also respond to anticonvulsants, benzodiazepines, and narcotics. Patients must stay on these medications in order to experience relief, because there is no known cure for this disorder.

PLMs tend to be exacerbated by tricyclic antidepressants, SSRIs, stress, and sleep deprivation. It is also advised not to consume caffeine, alcohol, or antidepressants as these substances could worsen the PLMD symptoms.

Other medications aimed at reducing or eliminating the leg jerks or the arousals can be prescribed. Non-ergot derived dopaminergic drugs (pramipexole and ropinirole) are preferred. Other dopaminergic agents such as co-careldopa, co-beneldopa, pergolide, or lisuride may also be used. These drugs decrease or eliminate both the leg jerks and the arousals. These medications are also successful for the treatment of restless legs syndrome.

In one study, co-careldopa was superior to dextropropoxyphene in decreasing the number of leg kicks and the number of arousals per hour of sleep. However, co-careldopa and, to a lesser extent, pergolide may shift the leg movements from the nighttime to the daytime.

Clonazepam (Klonopin), in doses of 1 mg has been shown to improve objective and subjective measures of sleep.

Reducing the dosage of the antipsychotic drugs resulted in gradual improvement in the abnormal posture. In some cases, discontinuing the use of those drugs resulted in complete disappearance of the syndrome. The time it took for the improvement and the disappearance of the syndrome depended on the type of drug being administered or the specific cause of the syndrome itself.

Treatment of sleep apnea via a continuous positive airway pressure (CPAP) device has shown dramatic improvement in apnea and nearly complete resolution of RMD symptoms. Behavioral interventions may alleviate some RMD symptoms and movements. In such a therapy, sufferers are asked to perform RMD-like motions during the day in a slow and methodic manner. In such, patients come short of full rhythmic movements that they experience in sleep. Such behavioral training has been shown to carry over into sleep, and the forcefulness of the RMD movements is reduced or eliminated. Hypnosis and sleep restriction have been used in some cases to good effect.

Medications that impede the release of excitatory neurotransmitters have been used to control or prevent spasms. Treatment with intrathecal baclofen, a gamma-aminobutyric acid (GABA) agonist, decreases muscle tone and has been shown to decrease the frequency of muscle spasms in ADCP patients. Tetrabenazine, a drug commonly used in the treatment of Huntington's disease, has been shown to be effective treating chorea.

Lesionsing is the intentional destruction of neuronal cells in a particular area used for therapeutic purposes. Though this seems dangerous, vast improvements have been achieved in patients with movement disorders. The exact process generally involves unilateral lesioning in the sensorimotor territory of the GPi. This process is called pallidotomy. It is believed that the success of pallidotomies in reducing the effects of movement disorders may result from the interruption of abnormal neuronal activity in the GPi. This ablation technique can be viewed as simply removing a faulty piece of a circuit. With the damaged piece of the circuit removed, the healthy area of the circuit can continue normal function.

Prevention of tardive dyskinesia is achieved by using the lowest effective dose of a neuroleptic for the shortest time. However, with diseases of chronic psychosis such as schizophrenia, this strategy must be balanced with the fact that increased dosages of neuroleptics are more beneficial in preventing recurrence of psychosis. If tardive dyskinesia is diagnosed, the causative drug should be discontinued. Tardive dyskinesia may persist after withdrawal of the drug for months, years or even permanently. Some studies suggest that physicians should consider using atypical antipsychotics as a substitute to typical antipsychotics for patients requiring medication. These agents are associated with fewer neuromotor side effects and a lower risk of developing tardive dyskinesia.

Recent studies have tested the use of melatonin, high dosage vitamins, and different antioxidants in concurrence with antipsychotic drugs (often used to treat schizophrenia) as a way of preventing and treating tardive dyskinesia. Although further research is needed, studies reported a much lower percentage of individuals developing tardive dyskinesia than the current prevalence rate for those taking antipsychotic drugs.

Physical therapy and Occupational Therapy are staple treatments of ADCP. Physical therapy is initiated soon after diagnosis and typically focuses on trunk strength and maintaining posture. Physical therapy helps to improve mobility, range of motion, functional ability, and quality of life. Specific exercises and activities prescribed by a therapist help to prevent muscles from deteriorating or becoming locked in position and help to improve coordination. Occupational therapy interventions for children with CP can include feeding, dressing, bathing, toileting, grooming, pencil grasp and handwriting skills, play, and use of adaptive equipment.
