Glassquilt is correct about strokes. My husband had a stroke when he was 40 and it was a ruptured blood vessel. However, after rupturing, it formed a clot so he will be on an aspirin daily for the rest of his life. Fortunately, he recovered probably 98% and only has problems with cognition (finding the right words or understanding written directions). My hubby just turned 56. I worked at a hospital at that time doing transcription but had seen enough to know we needed to get to the hospital quickly.
