Memory and cognition, vision and hormones are all strongly influenced by diet, and anything that may interfere with your digestion. If candida is at the root of your problem, which sounds pretty much certain, then I think you can be hopeful of an improvement in these areas too.
I was going to ask a similar question about muscles and nerves. I’m convinced good digestion is the answer to all my problems, but I’d like to hear some stories from people who’ve recovered from similar problems to myself, or read some research about the effects of candida or other digestive problems on muscle/nerve function.
Maybe we could try putting together a candida symptoms thread with links to information or success stories for each ailment.
