I did check on some old posts on this subject, but still feel confused. I have been ill for over 27 years with ME/CFIDS/FM/MCS, etc..., but recently scored strong on an autism self-test. Never have I ever been tested for any such thing, but will admit that the multiplicity of symptoms which have assailed me since becoming ill years ago could cause one to wonder about various diagnoses as a result. Is it ME brain damage? Does someone either have autism either diagnosed or not diagnosed all their life, but just never know it? Can you develop it later in life due to a brain injury or inflammation? Have you ever heard of this in serious CFIDS/ME research?
