New to this forum but use others here. My 82 yr old father in law is having a very specific memory issue. He keeps thinking is wife Babs is elsewhere, over the road (where her sister lives), that there are 3 Babs etc. When he thinks this, he just think his wife is a lady in the house, no agitation or fear.
Strange thing is how this comes and goes, it's like a switch is flicked off, and he suddenly forgets, then just as quick he's back to normal. He can be perfectly normal for days, then have a bad morning. There are no other dementia like symptoms other than forgetting the word he was trying to say.
He's been scanned for mini stroke (all clear) and has had eeg (or whatever the heart scan is) all clear. He's hypothyroid - levels are normal - b12 was a bit low at 300 now supplementing for last 6 weeks.
We done lots of reading about dementia and Alzheimer's but what he's experiencing doesn't seem to match any of the usual presentations described.
Has anyone else experienced this? Or heard of something similar? Ir is it just a different kind of presentation?
Any thoughts before he goes to doctors again on Monday gratefully received
