I am 55, female, and have developed a dreadful memory. I know people forget things, but, on times I get worried about dementia, I've done a memory test with the doctor which I passed, that sort of thing I can do easily. But its day to day life, for example I take zapain for cluster headaches, I usually take half of it out as I find they make me really sleepy, today I am not sure if I've accidentally taken a whole one. I have to double check appointment times.
