A stroke, often referred to as a cerebrovascular accident (CVA), occurs when blood flow to a part of the brain is interrupted or reduced, leading to damage or death of brain cells. Strokes can be classified into two main types: ischemic strokes and hemorrhagic strokes. Ischemic strokes occur when a blood clot blocks a blood vessel supplying the brain, while hemorrhagic strokes occur when a blood vessel in the brain ruptures or leaks. Strokes are a medical emergency and require immediate treatment to minimize brain damage and prevent complications. Common symptoms of stroke include sudden numbness or weakness of the face, arm, or leg, especially on one side of the body; sudden confusion, trouble speaking, or understanding speech; sudden trouble seeing in one or both eyes; sudden trouble walking, dizziness, loss of balance, or coordination; and sudden severe headache with no known cause. Risk factors for stroke include high blood pressure, high cholesterol, smoking, diabetes, obesity, physical inactivity, excessive alcohol consumption, and a family history of stroke. Prevention strategies focus on controlling these risk factors through lifestyle modifications such as eating a healthy diet, exercising regularly, quitting smoking, maintaining a healthy weight, and managing underlying medical conditions. Early recognition of stroke symptoms and prompt medical attention are critical for improving outcomes and reducing the risk of disability or death.

Treatment for stroke may include medications to dissolve blood clots (in the case of ischemic stroke), surgery to repair blood vessels (in the case of hemorrhagic stroke), rehabilitation therapy to regain lost functions, and lifestyle modifications to prevent future strokes. By raising awareness about stroke risk factors, symptoms, and prevention strategies, individuals can take proactive steps to reduce their risk of stroke and improve their overall health and well-being.
