In Parkinson's disease, orthostatic hypotension increases the risk of which complication?

Explanation:
Orthostatic hypotension in Parkinson's reflects impaired autonomic control of blood pressure. When you stand, the normal reflexes raise heart rate and constrict peripheral vessels to maintain cerebral perfusion. In Parkinson's, autonomic degeneration blunts those responses, so standing causes a drop in blood pressure and dizziness or lightheadedness from reduced brain blood flow. That dizziness and impaired balance greatly increase the risk of collapsing or falling, making falls the most common and important complication. Seizures, strokes, and arrhythmias aren’t the direct consequence of the standing BP drop in this context.
