Lixy....my great grandfather and my grandfather both had alzeimers and had some of the same symptoms. However, both of them were very aware of their environments, they just thought they were in a different time.

Dementia can be caused by many things, and I am happy BIL is getting another set of opinions.

Lixy....I hope I will not step on your toes here....but IMHO you are too worried about stepping on BIL's toes. She's your sister! And....BIL might appreciate some help and a shoulder to cry on, even if he doesn't always admit it. Just make sure -- should this be something fatal, or she slip away mentally -- thet you don't end up with any regrets about what you didn't do or didn't say. Life is short, and we never get to spend enough time with the ones we love.

One of my greatest regrets in life is that I didn't get to see my dad before he died.....and I've tried to make it different with the rest of my family.

(((((Lixy)))))) I know your life is so full of responsibility and care right now. I wish I could share some of the burden. Please take care of yourself, sweetie.
