Catatonia: A rare presentation of Wilson's disease.

Wilson's disease (WD) or hepatolenticular degeneration is a rare inherited disorder of copper metabolism affecting both the liver and the central nervous system. Psychiatric manifestations may precede neurological signs in the early stages of WD, but catatonia is a rare presentation. Here, we report a case of an 18-year-old girl who presented to the psychiatry outpatient department with catatonia. She was subsequently diagnosed to have WD. Her symptoms improved on treatment with trientine, trihexyphenidyl, zinc acetate, and benzodiazepine.
