A stroke is a type of cerebrovascular disease that occurs when the blood supply to the brain is interrupted. This can be due to a blockage or bleeding in the brain. A stroke is a medical emergency and can lead to death or disability if not treated promptly.

There are two types of stroke: ischemic and hemorrhagic. Ischemic stroke occurs when the blood supply to the brain is blocked, usually by a clot. Hemorrhagic stroke occurs when a blood vessel in the brain bursts and bleeds into the brain.

A stroke can cause a wide range of symptoms, depending on the area of the brain affected. These can include weakness, paralysis, difficulty speaking, difficulty understanding, loss of balance, and vision problems.

A stroke is a medical emergency and requires immediate treatment. Early treatment can help minimize the damage to the brain and improve the person's chances of recovery.

You can help prevent a stroke by managing conditions that increase your risks, such as high blood pressure, diabetes, and high cholesterol.

Eating a healthy diet, exercising regularly, not smoking, and limiting alcohol intake can also help reduce your risk of stroke.
