Recognizing the 10 Key Indicators of a Stroke

Every second counts when someone is having a stroke. Without immediate treatment, brain cells begin dying—millions each minute—raising the risk of long-term disability or death. The faster you recognize the warning signs, the better the chance of recovery.

1. Weakness

One of the most common early signs of a stroke is sudden weakness or numbness on one side of the body—especially in the face, arm, or leg. If someone can’t raise both arms evenly, or if their smile appears lopsided, it could indicate a stroke. The weakness typically affects the side opposite the part of the brain where the stroke is occurring.
