ABSTRACT
CASE PRESENTATION A 24-year-old man from Hong Kong was evaluated for the gradual onset of a tremor affecting his right arm, of 6 months’ duration. The tremor was initially noticed when holding plates at his job in his father’s restaurant. Over time his handwriting had become difficult and his right arm felt slightly stiff and clumsy. He also complained of a decline in his short-term memory and the need to write things down to remember them. He was previously very bright. He held a bachelor’s degree in finance and accounting and had worked temporarily for a financial corporation in New York City, but left because of not being able to tolerate the high job stress. He reported mood lability, uncontrollable laughter during socially inappropriate times, and difficulty controlling sexual impulses.
