What is a Stroke?

A stroke happens when the blood supply to any part of your brain is stopped. Damage to brain cells happens within minutes, so it is important to get medical help immediately.

Mild stroke or TIA (transient ischemic attack)

Blood flow is temporarily interrupted to the brain. Signs and symptoms of this type of stroke last for minutes to hours and then disappear. A stroke is more likely to happen after. It is important to seek care even if symptoms resolve.

Ischemic stroke

Is caused by a blockage or clot in a blood vessel in the brain

Hemorrhagic stroke

Is caused when a blood vessel suddenly leaks or ruptures inside the brain.
