Sometimes symptoms of a stroke are difficult to identify. Unfortunately, the lack of awareness spells disaster. The stroke victim may suffer severe brain damage when people nearby fail to recognise the symptoms of a stroke.
Now doctors say a bystander can recognise a stroke by asking three
S Ask the individual to smile.
T Ask the person to talk and speak a simple sentence (coherently).
R Ask him or her to raise both arms.
If he or she has trouble with any one of these tasks, call the emergency services immediately and describe the symptoms to the dispatcher.
Another sign of a stroke is a crooked tongue. Ask the person to stick
out his tongue... if the tongue is crooked, if it goes to one side
or the other, that can also be an indication of a stroke.
