When someone experiences any sign that could be a stroke, it's crucial to get that person to the hospital immediately. In general, the following signs of stroke appear suddenly (seemingly out of the blue):

  • Weakness or numbness in the face, arm or leg, especially on one side of the body
  • Confusion or trouble speaking or understanding speech
  • Trouble seeing with one eye or both, such as blurred vision or seeing double
  • Trouble walking, lack of coordination or stumbling
  • Dizziness or loss of balance
  • Severe headache with no known cause

Hospitalization and treatment for strokes

Treatments can reduce or completely reverse brain injury – but only if they're given in the first few hours after stroke symptoms appear. Call 911 to get the fastest possible transportation to the emergency room.
