Physical signs that may indicate a stroke include sudden numbness or weakness of the face, arm, or leg (especially on one side of the body); sudden confusion, trouble speaking or understanding; sudden difficulty seeing in one or both eyes; dizziness, loss of balance, or loss of coordination; or a sudden severe headache with no known cause. Seek immediate medical help if these signs are present.
