That surgery does change the personalities of the individual having that surgery...I've mentioned before my husband had a quad by pass, and with in the first year, our family noticed a change in his attitude, and his thinking...
Difficult surgery..and healing takes a toll on family members. but it is ‘life saving’ surgery...
I seldom watch Neil any more, but did watch his eulogy to Brenda Buttner, and it was well done,with dignity...I always watched her ‘bulls and bears’ show on Saturdays...she will be missed by all and most especially her young family..
I think the surgery changes the amount of oxygen that gets to the brain.
It’s the same thing that changes the personality in dementia
