Stroke occurs when blood flow to the brain is disrupted, leading to brain cell damage. It can be categorized as ischemic stroke, caused by a clot blocking blood flow, or hemorrhagic stroke, caused by bleeding in the brain. Common symptoms include sudden numbness or weakness, confusion, trouble speaking or understanding, vision problems, dizziness, and severe headaches. Stroke is a medical emergency, and prompt treatment is crucial. Diagnosis involves physical examination and imaging tests. Treatment may involve clot-busting medication or a thrombectomy procedure. Rehabilitation plays a vital role in recovery. Lifestyle changes and preventive measures, such as managing blood pressure, controlling cholesterol levels, and adopting a healthy lifestyle, are essential for stroke prevention.
