Dad has moderate dementia. Over the past several years, he's had 'senior moments', but it wasn't until last summer that things became noticeably bad. He's 81 and it's almost like someone flipped a switch; it came on so fast.
Based on the quick onset, is there any sort of timetable with regard to when he will lose function? He's now at the stage where he is fine for the most part, takes a nap and wakes completely lost, not understanding where he is, why he isn't at work, etc. It's happening more and more. He's also waking me in the middle of the night (last two nights) in a panic because he thinks he's late for work. Yesterday, I left him (explained thoroughly, left with cell phone, note of where I was) and he called me completely freaked out about where he was. This doesn't usually happen during the day.
I know everyone is different, but I'm just trying to find out how long it will take before he doesn't recognize me, becomes completely incontinent or starts losing his ability to eat and speak.
I'm totally on my own; no family, friends or caregivers. I'm not even sure I can get him into a nursing home because he's in that 'sour' spot of making too much to qualify for Medicaid but not enough that we can afford a home. So any guesstimates as to how long this may take would be appreciated.
