What Is a Stroke?

A stroke happens when blood flow to part of the brain is interrupted, either by a blocked artery (ischemic stroke) or a burst blood vessel (hemorrhagic stroke). Without oxygen-rich blood, brain cells begin to die within minutes, making stroke a medical emergency.

Know the Warning Signs: BE FAST

Recognizing stroke symptoms early can make a life-saving difference:

• Balance: Sudden loss of balance or coordination
• Eyes: Sudden trouble seeing in one or both eyes
• Face: Face drooping on one side
• Arms: Arm weakness or numbness
• Speech: Slurred speech or difficulty speaking
• Time: If you see any of these signs, call 911 immediately

Who Is at Risk?

Anyone can have a stroke, but risk increases with:

• High blood pressure
• Diabetes
• High cholesterol
• Smoking or vaping
• Heart disease
• Obesity and physical inactivity

Steps You Can Take to Prevent Stroke

Up to 80% of strokes may be preventable with healthy lifestyle choices:

Why Awareness Matters

Stroke is a leading cause of long-term disability in the U.S., but fast treatment improves outcomes and can reduce disability. Many treatments are time-sensitive, underscoring why immediate action is critical.
