An older adult patient presents to the emergency department with a sudden onset of left-
sided weakness and difficulty speaking. He has a history of hypertension that is not well-
documented and does not regularly take any medications. A CT scan of his brain reveals a
hemorrhagic stroke localized in the basal ganglia. There is no history of head trauma or
recent anticoagulant use. What is the most likely cause of this stroke?
O Long-standing hypertension
Hemorrhagic transformation of an ischemic stroke
Cerebral amyloid angiopathy
Rupture of a cerebral aneurysm
