Neurology: Case of the Month

History and Physical — Patient 33

History

Present Illness: Patient #33 is a 32 year old right-handed Filipino man who presented for evaluation of tremors. His symptoms started five years ago when he noticed that his hands would shake when he reached for a cup or shaved. He also noticed that he would drag his right leg with occasional tripping. These symptoms slowly worsened to the point that the tremor persisted during rest, causing him to leave his job as an ICU nurse. He also noticed balance problems, although he has not fallen. However, when his young son pushes him, he staggers backwards and nearly falls. His wife also thinks that he is "walking like a robot". Recently, he noticed involuntary movements of his mouth. His hands tend to cramp if he makes a fist, and this worsens as the day progresses. However, he has not experienced writer's cramp. Stress and fatigue worsen all of these symptoms. He denies bruxism, change in speech, visual changes, weakness, or numbness.
