Stroke.Org and several other major medical organizations have developed the symptom recognition tool for tool called FAST. But recently, a new general symptom for recognizing that a stroke is imminent has been added.
First, what is Fast?
Well Now, it seems that the T is Fast should be replaced to stand for the TONGUE.
For example, If you, or a suspected person, falls for no good reason, or excuses it as a "new shoe" or "bum knee" ask them to humor you and stick out their tongue. If the tongue is crooked to one side rather than straight, THIS MAY INDICATE A STROKE.
Another example. If you or a suspected person is complaining of numbness on one side of their body, you may also want to apply the tongue check, or the entire fast routine.
