I have known a few demented people in my time but none with dementia that I know of. Mother's best friend's husband has dementia. It is a bit hard to tell as he has always been vague. We recently attended his 70th birthday at the Cuckoo Restaurant in the Dandenong Ranges as his guests, rather than like Mother's 80th at the same venue where each person had to pay for their own food and drinks. The difference is they are rich. Our family gave him a $100 voucher for his favourite big tin shed store, Masters, and a writing pen which we had engraved, for around $80. His wife is very kind and generous to Mother, so it is a minor way to repay her. Given he has dementia, we were all a little surprised at the gift his wife gave him, a voucher for a trip on his own on the Spirit of Tasmania to see his sister. His wife doesn't like Tasmania and refuses to ever go there.
A little closer to home I had an odd conversation with a neighbour, who said, "I am taking N out shopping as his licence (driving) has been taken away from him". I did not ask why, but I recall this neighbour previously saying in passing something like N was going crazy. Now things were making sense. He must have dementia. The neighbour who told us is older than N and like some men of his age, is a shocking gossip.
N was a school principal and his wife a teacher . They were deemed superfluous to requirements during the Kennett state government era, and took voluntary (forced) departure packages. They own their apartment here and have recently sold their holiday house on the Bellarine Peninsula. Usually they take an overseas holiday every year but that has come to end now as they are too old to undergo the rigours of travel, even at the pointy end of the plane. Their life has now been much reduced. Kind of sad, but part of the process of ageing.
Note: After I began this post some time ago, I have since chatted to N and he told me he has early onset dementia. He is not worried about not being able to drive and is quite enjoying using public transport. His wife still drives, but lordy, is she a shockingly cautious driver, quite a road hazard really. She has had her own serious health issues and nearly died from a blockage to her lungs and I really feel for her. While she is sharp as a tack, N in the 12 or so years we have known him has always been a smart mouthed grumpy old man and has never stood back from being critical of her. At some point, the positions will be reversed, where he can no longer try to bully her. Don't feel sorry for her though. She is financially independent and he is the one who will be dependant on her.
