Hi Bella,
Just saw your post. I was a while ago but no one has replied yet.
Not sure where you're living, but there are many support groups for people with young onset dementia (I'm assuming that's what you mean by premature Alzheimer's?)
Having young onset dementia (be it, Alzheiner's, frontotempotal dementia, Pick's, etc) can be devastating, not just to the person, but to their career, their family (often still have young children at home), their social life and future care options.
If you're in the US, a local chapter of the Alzheimer's Association. Depending on where you are, they may have support groups, education sessions, therapy, etc. Find your local chapter in the US here:
