If you have any of these symptoms, call 911 or other emergency services right away:
Call 911 if you have symptoms that seem like a stroke, even if they go away quickly. You may have had a transient ischemic attack (TIA). A TIA is a warning that a stroke may happen soon. Getting early treatment for a TIA can help prevent a stroke.
An ischemic stroke happens when a blood vessel (artery) supplying blood to an area of the brain becomes blocked by a blood clot.
A hemorrhagic stroke happens when an artery in the brain leaks or bursts (ruptures).
Emergency treatment may be done to restore blood flow to the brain using medicine or a procedure. Medicine and a heart-healthy lifestyle can help prevent another stroke. A stroke rehab program can help you recover and learn ways to adapt to changes caused by a stroke.
An ischemic stroke develops when a blood vessel (artery) supplying blood to an area of the brain becomes blocked by a blood clot. The clot may form in the blood vessel (thrombus) or travel from somewhere else in the blood system (embolus).
An ischemic (say "iss-KEE-mick") stroke occurs when a blood clot blocks a blood vessel in the brain. This means that blood cannot flow to some part of the brain. Without blood and the oxygen it carries, this part of the brain starts to die.
This is different from a hemorrhagic (say "heh-muh-RA-jick") stroke, which happens when a blood vessel in the brain has burst open or has started to leak.
The brain damage from a stroke starts within minutes. The part of the body controlled by the damaged area of the brain cannot work properly. Quick treatment can help limit damage to the brain and make recovery more likely.
The problems someone has after a stroke depend on what part of the brain was affected and how much damage the stroke caused. A stroke may affect movement and senses, speech, memory, thinking, or emotions. Stroke rehabilitation, which includes training and therapy, can help people recover.
An ischemic stroke is caused by a blood clot that blocks blood flow in the brain. Causes of blood clots include:
