I found it from my sister-in-law tonight that her husband has dementia. She is an incredibly kind, caring woman, and I may find myself breaking my self-imposed ban on flying to go up to New York and see her. Dementia is a bitch; I know it's a hard road to walk. I remember how much it helped when my daughter would stop by while my husband was sick, even if she couldn't stay long. They never had kids, and her only surviving sibling lives in Australia.
