Maybe thinking you have dementia should be listed as one of the main meno symptoms, it's definitely one of the scariest, and most unexpected - brain fog sounds such a gentle phrase it doesn't really prepare you for it. You see changes to your body all through your life, but your brain stays basically the same for so many years and then suddenly goes weird.
Tiredness is the cause of it for me, when i'm sleeping well it's so much better. Like Sparkle I sometimes have trouble reading, words jump about a bit or i just read them wrong, and typing wrong letters can come up with some interesting new words. Newsreaders don't make sense when i hear them wrong - sex instead of sects makes the news more interesting, and as for getting words wrong when your'e out in public - worst so far was in the supermarket - orgasmic instead of organic.
Love the look husband sometimes gives me, he doesn't say a word, just that look.
