Down Syndrome with early onset dementia

Hi! My daughter, born with DS is 31 years old and started showing signs of dementia long before I realized what was happening. I had planned for so many different problems, but not once did I think this would be it. As I watch her decline, it breaks my heart and all I can do is try to keep life as normal as possible. My Mom passed in 2017 after living with me for 5 years, succumbing to lewy body dementia, and part of me feels like I just don't know how to go through this all again. Soo, anyone else out there with a similar situation? Wishing peace and comfort to all on these forums.
