answer:I think it depends on what parts of the brain are affected. I do think people tend to adjust to their new reality. As the new reality sets in and the person realizes this is the rest ofntheir life, usually depression accompanies the loss. It’s a loss, a grieving process. Most likely the older an individual is the better they handle it for several reasons. One reason is there is scietific research showing as we age our brains focus more on good than bad. Young people get hit hard psychologically by emotional and physical set backs. For me personally, I definitely am much much happier in my late 30’s amd 40’s even though I have had disappointments including physical limitations and discomfort. I am better able to appreciate the good things I have and simple things like the love I feel from my family, beautiful scenery, music. I will say my biggest fear would to be in pain and not be able to communicate it somehow. But, I would assume your mom was still able to write and show people if something was bothering her. Even still, I would guess she was less able to participate in conversations, it must have been frutsrating. I had a friend whose father suffered a stroke that affected his speech. Hos dad and mothered had stayed with me for two months at one time, I was very close to them. When he had his stroke his therapy was to regain only hist first language and I no longer could communicate with him, and his language was still not completely regained so his family also had some trouble. He was a smart, loving man, and he became quiet and withdrawn to some extent. I feel he felt stifled and frustrated. But, they still travelled, spent lots of time with family, he still had some enjoyment I believe.
