There are two main causes of stroke. An ischemic stroke is caused by a blocked artery in the brain. A hemorrhagic stroke is caused by leaking or bursting of a blood vessel in the brain. Some people may have only a temporary disruption of blood flow to the brain, known as a transient ischemic attack (TIA). A TIA doesn't cause lasting symptoms ...
Healthcare professionals try to find the cause of the stroke to determine the proper treatment. If you're seeking medical advice during a scheduled appointment, your healthcare professional considers your risk factors for stroke and heart disease.

What is a stroke? A stroke occurs when the blood supply to your brain is suddenly disrupted, preventing brain tissue from getting oxygen and resulting in brain cells dying. This injury to the brain causes a neurologic deficit (impaired functioning, such as an inability to speak or walk normally). There are two forms of stroke: Ischemic stroke ...
This blockage may cause temporary stroke-like symptoms. But a TIA doesn't damage brain cells or cause permanent disability. This is how it differs from a regular stroke.
Strokes that block a brain artery usually cause a range of symptoms that may include vascular dementia. But some strokes don't cause any noticeable symptoms. These silent strokes still increase dementia risk.
Stroke is a leading cause of death and disability in the U.S. Carotid artery disease often develops slowly. The first sign of the condition might be a stroke or transient ischemic attack (TIA).
Stroke rehabilitation is a program of different therapies designed to help you relearn skills lost after a stroke. Rehabilitation methods can depend on the parts of your brain affected by the stroke. Rehabilitation can help with movement, speech, strength and daily living skills.
