PATHOLOGY

Detailed explanation-1: -An ischemic stroke occurs when a blood vessel that supplies the brain becomes blocked or “clogged” and impairs blood flow to part of the brain. The brain cells and tissues begin to die within minutes from lack of oxygen and nutrients. Ischemic strokes are further divided into 2 groups: Thrombotic strokes.

Detailed explanation-2: -Hemorrhagic strokes make up about 13 % of stroke cases. They’re caused by a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue.
