As a mod-severely limited medical professional w/this illness, I had severe incapacitating migraines in my initial group of symptoms later dx's @ Cheney clinic plus Qeeg brain mapping. By that time my cognitive deficits were there to live with now for years. Dr Natelson is a bright neuro doctor, who does not cringe at the dx as majority of drs do. He wrote book how our symptoms are real and has Gulf War studies and work w/veterans which go back years. He is no youngster, as many of us have seen ourselves and our critical dr/researchers aging. Think it is frustration on some part as Floydguy is right that we could show gratitude but some are more bitter than appreciative and can understand where it comes from. But, I do respect and know that Dr. Natelson is working w/younger researchers at top facilities in NYC. Just my two cents (rarely given) SueC
