En ärftlig, autosomalt dominant sjukdom, kännetecknad av utveckling av korea (danssjuka) och demens i 40-50-årsåldern. Vanliga tidiga manifestationer är paranoia, impulsivitet, depression, hallucinationer och vanföreställningar. Senare följer mental försämring, förlorad finmotorik, atetos, diffus korea som omfattar lemmarnas muskler, och efter 10-15 år inträder ett vegetativt tillstånd. Ungdomsvarianten har ett våldsammare förlopp, med krampanfall, ataxi, demens och korea.
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)
