Driving Under the Influence: An Unusual Case of Basal Ganglia Stroke Misdiagnosed as Intoxication

Traditionally, strokes are characterized by negative symptoms, including contralateral hemiparesis, facial paralysis, and sensory loss in the upper face and upper extremities. Strokes rarely cause movement disorders such as ballismus, a severe chorea characterized by brief, sudden dance-like movements. Early identification of non-traditional stroke symptoms and risk factors for cerebrovascular disease is vital in providing timely treatment and improving patient outcomes. Our case highlights an uncommon complication of stroke and the need to use advanced imaging modalities, including MRI, to identify brain lesions when other testing is negative. This report adds to the body of literature highlighting ballismus, a rare presentation of stroke, and the lessons learned from managing this case.
