Stroke (CVA)

A cerebrovascular accident (CVA), also known as a stroke, happens when the blood supply to the brain is disrupted, causing damage to brain tissue due to lack of oxygen.

Ischemic Stroke

Ischemic strokes, which occur in approximately 88% of strokes, are caused by a blockage in a blood vessel, usually due to hardening of the arteries (arteriosclerosis) or high blood pressure (hypertension).

Hemorrhagic Stroke

Hemorrhagic strokes occur when a blood vessel in the brain ruptures, leading to bleeding and damage to brain tissue. Recovery is often less favorable compared to ischemic strokes.

Lacunar Stroke

Small, localized strokes are called lacunar strokes. Some individuals experience complete recovery from these, while others may have lasting symptoms.

Stroke Severity

Strokes can vary in severity, ranging from small, localized strokes (lacunar) with full recovery to larger, more extensive strokes with permanent symptoms.

Study Notes

Cerebrovascular Accident (CVA) - Stroke

Stroke is a disruption of blood supply to the brain, causing anoxia (lack of oxygen) and brain tissue death.
Strokes can vary in severity; some individuals recover fully from small lacunar strokes, while others experience lasting symptoms.
Ischemic strokes are the most common type, accounting for about 88% of all strokes. They result from blocked blood vessels, often due to narrowed arteries (stenosis) from arteriosclerosis or high blood pressure.
Hemorrhagic strokes involve a ruptured blood vessel, often an arteriosclerotic one. Recovery from hemorrhagic strokes is often less complete compared to ischemic strokes.
