Spotting signs: Face

A quick glance can often catch a stroke symptom: one of the face might droop, sag or otherwise not look like the other.

From the Web site eHow:

Look at the face and ask the person to smile. Determine if the smile is crooked or if one side of the face appears to be paralysis or stiff. If the face does show a marked difference between the two sides, a stroke may be in progress. Call an ambulance and get the person to the hospital immediately.

It's good to check someone for all symptoms if you see just one, but just one is enough to get help right away. Not all symptoms show up in every person who is having a stroke.
