Stroke is a medical condition in which the blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. This can cause brain cells to die, leading to permanent disability.

There are two main types of stroke: ischemic stroke and hemorrhagic stroke. Ischemic stroke is caused by a blockage in a blood vessel that supplies blood to the brain, while hemorrhagic stroke is caused by a ruptured blood vessel in the brain.

Common causes of stroke include high blood pressure, smoking, diabetes, high cholesterol, and atrial fibrillation.

Signs and symptoms of stroke can include sudden numbness or weakness of the face, arm, or leg, especially on one side of the body; confusion; trouble speaking or understanding; trouble seeing in one or both eyes; trouble walking; dizziness; and loss of balance or coordination.

Treatment for stroke depends on the type and severity of the stroke. Treatment may include medications to dissolve blood clots, medications to reduce swelling in the brain, and surgery to remove the clot or repair the damaged blood vessel. Rehabilitation may also be necessary to help the patient regain lost functions.
