Dementia

My sister, toward the end, displayed symptoms of dementia. Loss of memory and confidence being the most obvious, and it keeps crossing my mind – will this become my fate? I have always had a bad memory, forgetting where I’ve put the car keys – things like that. Heather has often joked, “If you get dementia, nobody would know.” But recently my bad memory seems to have got worse. A drama comes on the television that Cyril and Heather assure me we have seen, but I do not recall it at all.  This afternoon, for instance, I was in my chair in the summerhouse when H called out to me, “I’m off now!” 
I got out of the chair and walked up to the carport, “Where are you going?”
“I told you this morning, I’m doing some shopping.”
“Did you? Well, remember, keep away from people, six or seven feet, okay?”
“Yes, yes, don’t worry.”
I do worry, can’t help it. 
I didn’t recall her telling me she was going shopping today. This kind of memory lapse seems to be happening more often and it’s just a little bit worrying. I haven’t talked about it. I’m sure if I did Heather would want to pack me off down to the doctors for tests and once they’ve got me down as a possible dementia candidate who knows where I will end up? No, I won’t mention it.
