On the day after Thanksgiving 2015 my Mom had a stroke.  That was the start of a journey that continues to this day.  Mom is 88 years old, a survivor of colon cancer, the 50's and 60's and electric shock therapy for post partum depression.  She was feeling more and more tired each day for a few weeks before and her once voracious appetite had dwindled substantially.  Two weeks before when at the doctor's office we were told that......well, she is 88.....her blood tests were fine 6 months ago.......Etc., etc.   She was in AFIB.  Arterial Fibrillation......the heart receives too many signals to beat, leading to irregular heartbeat and blood collection which forms a clot and Presto!  A clot shoots out and, in this case, races to the right side of the brain causing a "massive" stroke.  The doc did not detect it.  We don't go there anymore.
