Huntington's disease (HD) is an inherited neurodegenerative disorder for which no disease-modifying treatment is currently available. Only symptomatic treatment can be offered. Chorea is the most common motor manifestation of HD and may interfere with daily activities, reduce quality of life and cause injury. Areas covered: Deutetrabenazine is the first deuterated drug and second drug after tetrabenazine, the classic vesicular monoamine transporter type 2 (VMAT2) inhibitor, to receive approval for the treatment of chorea associated with HD. This review, based largely on a detailed PubMed search, will summarize the pharmacological properties, clinical evidence of efficacy and tolerability of deutetrabenazine in the treatment of HD chorea. Expert Commentary: Due to differences in pharmacology and pharmacokinetics, deutetrabenazine has shown promise that it is at least as effective as tetrabenazine in the treatment of HD chorea but has a lower risk of adverse effects. The role of VMAT2 inhibitors in the treatment of hyperkinetic movement disorders is expanding due to their efficacy and favorable tolerability profiles.

For young people in families with Huntington's disease (HD) the challenge of having an affected family member (AFM) compounds challenges related to being at risk of HD themselves.

A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea. (From Adams et al., Principles of Neurology, 6th ed, pp1060-4)
A phenyl-piperidinyl-butyrophenone that is used primarily to treat SCHIZOPHRENIA and other PSYCHOSES. It is also used in schizoaffective disorder, DELUSIONAL DISORDERS, ballism, and TOURETTE SYNDROME (a drug of choice) and occasionally as adjunctive therapy in MENTAL RETARDATION and the chorea of HUNTINGTON DISEASE. It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279)
A rare movement disorder developed during PREGNANCY, characterized by involuntary jerky motion (CHOREA) and inability to maintain stable position of body parts (ATHETOSIS). RHEUMATIC FEVER and collagen vascular disorders are frequently associated with this disease. Chorea may vary from mild to severe and occurs in approximately 1 per 2,000 to 3,000 pregnancies. (From Md Med J 1997 Sep;46(8):436-9)
Involuntary, forcible, rapid, jerky movements that may be subtle or become confluent, markedly altering normal patterns of movement. Hypotonia and pendular reflexes are often associated. Conditions which feature recurrent or persistent episodes of chorea as a primary manifestation of disease are referred to as CHOREATIC DISORDERS. Chorea is also a frequent manifestation of BASAL GANGLIA DISEASES.
An inherited autosomal disorder that is characterized by neurodegeneration; orofacial and buccal DYSKINESIAS; CHOREA; and thorny-looking red cells (ACANTHOCYTES). This disorder is due to mutations of chorein which is important in protein trafficking and is encoded by Vps13a on chromosome 9q21.
Huntington's disease is a hereditary disease caused by a defect in a single gene on Chromosome 4 that is inherited in an autosomal dominant fashion. The defect causes a part of DNA, called a CAG repeat, to occur many more times than it is supposed to...
