Recognizing the symptoms of a stroke is crucial for timely intervention. Common symptoms include sudden numbness or weakness in the face, arm, or leg, especially on one side of the body, confusion, trouble speaking or understanding speech, sudden trouble seeing in one or both eyes, difficulty walking, dizziness, loss of balance or coordination, and severe headache with no known cause. The acronym FAST (Face drooping, Arm weakness, Speech difficulties, and Time to call emergency services) can help remember the warning signs.
