Strokes often occur without warning. In some cases, warning signs such as severe headache or transient ischemic attack (TIA) may occur before a stroke occurs.
A stroke occurs when blood flow is blocked or interrupted to some part of the brain. This prevents brain cells from getting the oxygen and nutrients they need to survive.
A stroke is a medical emergency that requires immediate treatment. Recognizing the symptoms of a stroke can help you get help as soon as possible.
Although stroke symptoms may appear suddenly, in some cases there may be warning signs that should not be ignored.
