On the SSD article: This claim is problematic. How do you assess that? Pacing might be considered an abnormal behavior. So might resting during the day. So might falling over or passing out from OI. So might taking supplements, or restricting the diet. In cases of CFS for example, with strong anxiety, then a diagnosis of CFS with anxiety might be appropriate, but SSD? The devil is in the details. Basically the only person who is safe under this is a mild CFS patient who is still struggling with full time work, and does not take any drugs or supplements and has not made any dietary or other changes. It doesn't help that there is no objective evidence that SSD or anything similar is a valid diagnosis, nor that like most such disorders it relies on subjective interpretation and the formal fallacy, the psychogenic fallacy. Until the psychiatric profession wakes up to the advances in biomedical testing for ME, any such disorder is dangerous because, to paraphrase one researcher (Steven Holgate?) , they are bathing in ignorance.
