Mom is 92. She had a small stroke last Oct..no permanent dmg done physically. Her left side coratid is completely closed due to plaque, etc. Last week she had 2 TIA s or (strokes) in the same night. Because of her age,no surgical procedures will be done. MRI shows TIA activity. Since then, she has changed quite a bit. She sleeps 20 hrs out of 24. This is not normal for her. Does anyone know if this typical ? I know her little body has been thru alot lately but im not sure if the sleeping is good or bad. So far the Dr's say the "big one" is coming probably sooner than later. Has anyone been thru this?
