Understanding Stroke Types

Strokes are primarily categorized as ischemic or hemorrhagic. Ischemic strokes occur when blood flow is blocked, often by a clot, leading to brain cell death. Hemorrhagic strokes happen when a blood vessel bursts, causing bleeding in or around the brain. Each type requires different treatment and has distinct causes.

Delving into Ischemic Strokes

Ischemic strokes are the most common, accounting for about 80% of strokes. They can be caused by thrombosis, embolism, or systemic hypoperfusion. Thrombosis involves a clot forming in a brain artery, while an embolism refers to a clot traveling from elsewhere to the brain. Systemic hypoperfusion results from poor blood flow due to heart issues.
A stroke occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients.

Unpacking Hemorrhagic Strokes

Hemorrhagic strokes can be caused by intracerebral hemorrhage or subarachnoid hemorrhage. Intracerebral hemorrhage involves bleeding within the brain, often due to high blood pressure or trauma. Subarachnoid hemorrhage occurs when an aneurysm bursts, spilling blood into the space around the brain, which can be life-threatening.
