A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Hemorrhagic stroke is the less common type. It happens when a blood vessel breaks and bleeds into the brain. Within minutes, brain cells begin to die. Causes include a bleeding aneurysm, an arteriovenous malformation (AVM), or an artery wall that breaks open.Symptoms of stroke areSudden numbness or weakness of the face, arm or leg (especially on one side of the body)Sudden confusion, trouble speaking or understanding speechSudden trouble seeing in one or both eyesSudden trouble walking, dizziness, loss of balance or coordinationSudden severe headache with no known causeIt is important to treat strokes as quickly as possible. With a hemorrhagic stroke, the first steps are to find the cause of bleeding in the brain and then control it. Surgery may be needed. Post-stroke rehabilitation can help people overcome disabilities caused by stroke damage. National Institute of Neurological Disorders and Stroke
