"Your body flashes signals -- symptoms and signs -- that warn you of potential problems," say Neil Shulman, MD, Jack Birge, MD, and Joon Ahn, MD. The three Georgia-based doctors are the authors of the book Your Body's Red Light Warning Signals.
But a sudden, agonizing "thunderclap" headache -- the worst of your life -- could mean bleeding in the brain. Being able to recognize this serious symptom and calling 911 may save your life.
Here is One Highlighted important flashing signal for this week.
1. Paralysis of the arms or legs, tingling, numbness, confusion, dizziness, double vision, slurred speech, trouble finding words, or weakness, especially on one side of the face or body.
These are signs of stroke -- or a "brain attack" -- in which arteries that supply oxygen to the brain become blocked or rupture, causing brain tissue to die.
Symptoms depend on which area of the brain is involved. If a large blood vessel is blocked, a wide area may be affected, so a person may have paralysis on one side of the body and lose other functions, such as speech and understanding. If a smaller vessel is blocked, paralysis may remain limited to an arm or leg, or even the face.
If you have symptoms, call 911 right away and get to an emergency room that offers clot-busting therapy for strokes due to blocked vessels. Such treatment, which dissolves clots in blocked vessels, needs to be given within the first 3 hours after symptoms begin, but newer treatments may work within a longer time frame, says Birge, who is medical director at the Tanner Medical Center in Carrollton, Ga.
Timing is urgent; fast treatment can potentially stop brain tissue death before permanent brain injury happens. "There is a time clock ticking as to when you might totally recover," Birge tells WebMD.
