Answer

Answer

Wilson disease is characterized by the presence of choreiform movements, tremors, diminished dexterity, marked rigidity, dystonia, dysarthria, and neuropsychiatric manifestations. The presenting manifestation may be psychosis. Check serum ceruloplasmin and the copper transporter gene in every patient in whom Wilson disease is suspected. The onset of movement disorders in patients younger than 50 years merits ruling out Wilson disease, a treatable disorder.
