Advice: Do you have intellectual or memory difficulties causing concern? Do you wish to undergo extensive and expensive testing to uncover potential issues which may or may not occur? You could contact a local medical school, see an experienced neurologist, or even undergo neuropsychological testing. You could also consider virtual consultation here at HT.
