Other risk factors include high blood cholesterol, tobacco smoking, obesity, diabetes mellitus, a previous TIA, end-stage kidney disease, and atrial fibrillation. The main risk factor for stroke is high blood pressure. Long-term complications may include pneumonia and loss of bladder control. The symptoms of a stroke can be permanent. A hemorrhagic stroke may also be associated with a severe headache. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. Signs and symptoms often appear soon after the stroke has occurred.

Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Both cause parts of the brain to stop functioning properly. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding.
