Stroke Signs & Warnings
Stroke can be caused either by a clot obstructing the flow of blood to the brain (called an ischemic stroke), or by a blood vessel rupturing and preventing blood flow to the brain (called a hemorrhagic stroke). A TIA (transient ischemic attack), or “mini stroke”, is caused by a temporary clot.
It’s very important to take immediate action at the first sign of stroke. Call 9-1-1 immediately so an ambulance (ideally with advanced life support) can be sent for you.
