We are dealing with it right now with my mother in law. My father-in-law passed away october of 2011, and at the funeral we realized she was worse than what we had thought, as she showed no emotion during the whole ordeal. She stayed at her house til we forced her into a assisted living facility two weeks ago. Yesterday the wife took her to the emergency room, she was kinda out of it and was running a temp. Turned out she had a urinary tract infection. They spent like 5 hours there last night. Today the wife went to check on her after work, and it was the first time she didn't realize my wife was her daughter. I can only imagine whats in store for the future. I think in the past two weeks it has gotten noticeably worse. I dunno if it is her being out of her element that done it, but it's definitely worse. If there is a god, then this is the most f'ed up thing he could do.
