hyperkinesia
Definition
An abnormal condition characterized by excessive or uncontrolled movement
Clinical context
A 28-year-old woman presents to the emergency department with sudden onset of involuntary jerking movements affecting her arms and legs. She reports that the movements started abruptly while she was at work and have been worsening over the past hour. Her neurological exam reveals symmetric, irregular movements that are not provoked by external stimuli, suggesting a movement disorder rather than a seizure. The patient has no history of similar episodes and denies any recent medication changes.
