Warning Signs of Stroke

Stroke Signs Image - Masterfile

Strokes, or brain attacks, are medical emergencies that require immediate medical attention. The American Stroke Association has identified several stroke warning signs. Remember that someone having a stroke may not experience all of the warning signs and that warning signs can come and go. Anyone having these symptoms should seek prompt medical attention. The sooner treatment begins, the more effective it is.

Warning signs of a stroke include the following:

  • Sudden numbness or weakness of the face, arm, or leg, especially on one side of the body
  • Sudden confusion, difficulty speaking or understanding
  • Sudden difficulty seeing in one or both eyes
  • Sudden difficulty walking, dizziness, loss of balance or coordination
  • Sudden severe headache with no known cause
