I hear you about the waiting lists and the hardships that families go through to place their loved ones with dementia. We had to wait three months for my grandmother to be placed, and luckily she wasn't violent or feisty- and that was back in the 70's!. I know of others that have gone through some very rough times while trying to take care of them at home. You can't leave them alone for a minute unfortunately. As I said before, anyone that has gone through this as a caretaker with a loved one or one who works in the profession of dealing with patients with dementia has very sad, traumatizing, scary, and at times, some comical stories, like the one where my grandmother thought she was ballroom dancing with some non-existent man. She was laughing and so happy, in her own world, twirling around- my grandmother never danced a day in her life. She got injured as a young child and had a hole in her leg that left her lame for the rest of her life. But God love her, she was so happy dancing away in her mind. Sadly, not all families have such fun stories to tell, like my cousin with her father. I had two uncles that had it as well as my sibling, I've worked with brain injured clients in the past, to which a few had dementia, and of course, took care of two members of my own family with it.
In this case, though- where Bobby's husband is the last person to see her alive, and they can't find her body anywhere, with him telling a different story to each family member- I feel he needs a medical check up. They may never find her body- who knows where she is? For all we know, he could have buried her himself with the earth, or worse....I just feel he needs to be checked out medically, and if it is proven he has dementia or any other brain trauma/injury, it needs to be addressed. His BIL said he might have dementia- not that he actually had it. Big difference. He also could have a brain tumor which may be the cause of him forgetting information.
Just my two cents, but as one who has worked with brain injured clients and dementia in the past, I really feel a check up is a must at this point- not just for his loved ones and other's safety, but his own as well.
