Uncontrolled hypertension is most strongly linked to which type of stroke?

• A. Ischemic stroke
• B. Transient ischemic attack
• C. Hemorrhagic stroke
• D. Subarachnoid hemorrhage

Answer: (C)

Uncontrolled high blood pressure injures small cerebral arteries, making them prone to rupture. Over time this causes hypertensive arteriolar changes like lipohyalinosis and hyaline arteriolosclerosis, weakening vessel walls and leading to bleeding into the brain tissue. When a penetrating artery ruptures, it produces an intracerebral (hemorrhagic) stroke, which is the stroke type most strongly linked to chronic hypertension.

Hypertension does increase stroke risk overall, including ischemic strokes, but the direct, strongest association is with hemorrhagic events due to vessel rupture. Transient ischemic attacks are temporary blockages and not the primary consequence of the vessel-wall damage seen with uncontrolled hypertension. Subarachnoid hemorrhage typically results from aneurysm rupture rather than hypertensive rupture of small deep arteries, though hypertension can contribute to vascular risk in general.
