A stroke, also known as a cerebrovascular accident (CVA), occurs when there is a disruption in the blood supply to the brain. This disruption can be due to either a blockage of blood flow (ischemic stroke) or bleeding into the brain tissue (hemorrhagic stroke). Strokes are medical emergencies and require immediate attention as they can result in brain damage and even death if not treated promptly.

Common symptoms of a stroke include sudden weakness or numbness 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, obesity, diabetes, atrial fibrillation, family history of stroke, and age (risk increases with age). Prevention strategies include maintaining a healthy lifestyle, managing risk factors, such as controlling blood pressure and cholesterol levels, quitting smoking, exercising regularly, and eating a healthy diet.

Treatment for stroke depends on the type and severity of the stroke but may include medication to dissolve blood clots (if ischemic stroke), surgery to repair blood vessel abnormalities (if hemorrhagic stroke), rehabilitation therapy to regain lost skills and improve functioning, and lifestyle changes to prevent future strokes. It’s crucial to seek medical attention immediately if you suspect someone is having a stroke or if you experience any of the symptoms yourself.
