Episode notes
Categorizing Involuntary Movements
- Involuntary movements can be seizures or various types of movement disorders like tremor, myoclonus, chorea, and dystonia.
- Identifying the type of movement aids in localization and differential diagnosis, often linked to basal ganglia circuits.
Unilateral Chorea Points to Structure
- Acute unilateral hemichorea suggests a structural lesion, often in the basal ganglia like the subthalamic nucleus.
- Systemic causes usually produce bilateral movements, but hyperglycemic chorea is a key exception presenting unilaterally.
Prioritize Stroke in Acute Movements
- In older patients with vascular risk factors and sudden onset involuntary movements, always consider stroke.
- Localize the lesion vascularly by correlating symptoms with brain areas and vascular territories.
