Understanding Brain Strokes: Types and Warning Signs
This article explains the two main types of strokes—ischemic and hemorrhagic—their causes, symptoms, and importance of immediate medical response. Early detection and quick action can save lives and prevent serious brain damage.
A stroke occurs when blood flow to the brain is interrupted or a blood vessel in the brain ruptures. Unlike a heart attack, strokes impact brain function and can cause lasting damage. There are primarily two types: ischemic and hemorrhagic. Recognizing symptoms early can save lives and reduce long-term effects.
Ischemic strokes happen when blood flow is blocked by a clot, either traveling from elsewhere (embolic) or forming locally (thrombotic). Hemorrhagic strokes involve bleeding due to ruptured blood vessels, often caused by high blood pressure or aneurysms.
Key symptoms include sudden weakness in the face, arm, or leg, difficulty speaking or understanding speech, dizziness, vision problems, and severe headaches. Hemorrhagic strokes may also cause nausea, seizures, loss of coordination, and paralysis. Immediate medical attention is critical for better recovery. Recognizing warning signs and acting quickly can make a significant difference.
