If you or a loved one is experiencing symptoms of a stroke, call 911 immediately. Brain damage can begin within minutes, and quick treatment can help increase the chances of a full and meaningful recovery.
An easy way to remember the signs and symptoms of stroke is to think FASST.
A stroke occurs when a blood vessel in the brain is blocked (ischemic) or bleeds (hemorrhagic). Blood carrying oxygen can't get to the brain and brain cells start to die. Damaged areas of the brain can lead to loss of bodily functions, such as speech, arm movement and sight, can be impaired.
Ischemic stroke – An ischemic stroke happens when there’s a clot or obstruction blocking the supply of blood going to your brain. Eighty-seven percent of all strokes are ischemic.
Hemorrhagic stroke – A hemorrhagic stroke occurs when a blood vessel ruptures.
Transient ischemic attack (TIA) – A transient ischemic attack or TIA is caused by a temporary clot. It’s often referred to as a “mini stroke” and serves as a warning stroke. TIAs should be taken very seriously.
Typically, a CT scan is the first test performed, during or after after a stroke. A CT scan will show whether the stroke was caused by a blocked artery or by a leaking or ruptured artery.
For a stroke caused by a clot or blockage, doctors might use:
Treatment for a stroke caused by a leaking or ruptured artery includes:
