Sticking out the tongue... to check for sign of a stroke?

I am always wary of "medical breakthrough" emails that I receive. So the usual caveat emptor applies here. You should definitely check out the Snopes link that I attached at the end:

Blood Clots/Strokes -- They Now Have a Fourth Indicator: the Tongue

STROKE: Remember the 1st Three Letters...
S. T. R. 
STROKE IDENTIFICATION:


During a BBQ, a woman stumbled and took a little fall - she assured everyone that she was fine (they offered to call paramedics) ....she said she had just tripped over a brick because of her new shoes.


They got her cleaned up and got her a new plate of food. While she appeared a bit shaken up, Jane went about enjoying herself the rest of the evening.

Jane's husband called later telling everyone that his wife had been taken to the hospital - (at 6:00 PM Jane passed away.) She had suffered a stroke at the BBQ. Had they known how to identify the signs of a stroke, perhaps Jane would be with us today. Some don't die. They end up in a helpless, hopeless condition instead.

  
It only takes a minute to read this...

A neurologist says that if he can get to a stroke victim within 3 hours he can totally reverse the effects of a stroke...totally. He said the trick was getting a stroke recognized, diagnosed, and then getting the patient medically cared for within 3 hours, which is tough.

RECOGNIZING A STROKE

Remember the 3 steps: STR. Read and
Learn!

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 recognize the symptoms of a stroke.

Now doctors say a bystander can recognize a stroke by asking three simple questions:

S *Ask the individual to SMILE.

T *Ask the person to TALK and SPEAK A
FEW WORDS (Coherently)
(eg. Chicken Soup)

R *Ask him or her to RAISE BOTH ARMS.

If he or she has trouble with ANY ONE of these tasks, call the emergency number immediately and describe the symptoms to the dispatcher.

  
New Sign of a Stroke
Stick out Your Tongue!

Another 'sign' of a stroke is this: Ask the person to 'stick' out his or her tongue. If the tongue is
'crooked', if it goes to one side or the other, that is also an indication of a stroke.
