I've pretty much had my HA under control for around 8 months now but this week I've suffered from the worst bout of brain fog I've ever had ! It started earlier this week when I started making stupid mistakes at work and now I can't concentrate or focus on anything. When I try, my mind is a complete blank. I can't seem to register anything!! It's quite a scary feeling because it feels like my mind has been wiped and I've forgotton how to do even the simplest of tasks. The more I try to concentrate the worse it gets. My head feels really fuzzy and it really is a case of the lights being on but nobody being at home! Does anyone else get this? xx
