Stroke Information

-- PASSING SOME INFO ALONG!

INFORMATION EVERYONE SHOULD KNOW........................

Blood Clots / Stroke - They Now Have a Fourth Indicator,

the Tongue












I will continue to forward this every time it comes around!



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



STROKE IDENTIFICATION:



During a BBQ, a friend 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, Ingrid went about enjoying herself the rest of the evening



Ingrid's husband called later telling everyone that his wife had been taken to the hospital - (at 6:00 pm Ingrid passed away.) She had suffered a stroke at the BBQ. Had they known how to identify the signs of a stroke, perhaps Ingrid 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 vic tim 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



Thank God for the sense to 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 vic tim 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 SIMPLE SENTENCE (Coherently)

(i.e. It is sunny out today.)

R *Ask him or her to RAISE BOTH ARMS.



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



New Sign of a Stroke -------- Stick out Your Tongue



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



A cardiologist says if everyone who gets this e-mail sends it to 10 people;
you can bet that at least one life will be saved.



I have done my part. Will you?
