Wish there was a simple answer yet there isn't, as Becky stated before me. Everyone responds a little different and progression varies. I used to take my Mom out but it became to hard for her - too much stimulation which would end up making her worse. I've had out of town family visit and we all sat in a bit of a private area in the memory care. You know him best. Just remember, it changes, fluctuates, gets better, worse or different. Hang in there, hope you find support.
