my question: hw true is this email?[/b]
It is quite accurate because those three tests mentioned are part of a battery of tests doctors perform on patients who are suspected to have suffered from strokes.
However, there are different types of stroke which manifests with different symptoms so those three are just a rough guideline. For instance, in Hemorrhagic Stroke cases, usually the victim would lose consciousness and collapse altogether and you wouldn't be able to run those three tests at all!
Tell you the rationale behind those three tests...
If the victim presents with a lop-sided smile, most likely, he/she is suffering from a stroke because facial muscles can be affected by strokes. Sometimes, the patient ends up with half of his / her face 'drooping' because the facial muscles on that side of the face had been affected.
Inability to raise one or both arms would indicate limb weakness, another sign of stroke. If one arm is raised higher than the other, it's also a sign. If the frontal region of the brain is affected by a stroke, weaknesses or inability to perform certain functions can be noted because our homunculus is located on the frontal region of our brain.
The frontal also controls behaviour and logic so any sudden behavioural changes, disorientation and confusion are also signs of stroke.
Asking the individual to speak a simple sentence will show if the person has slurred speech or not, as that is a sign of stroke if the Broca's or Wiernecke's part of the brain had been affected.
Bottom line is, when you note any or all of these symptoms, get the individual to the nearest hospital as fast as you can because depending on what type of stroke it is, the person can be rescued. In Ischemic Strokes, for instance, if IV anti-coagulants are infused timely, the clot can be dissolved and a serious stroke may be prevented.
