I came across a number of interesting Youtube videos which featured Dr Derek Enlander (who I had not heard of). One of the good guys and very anti-PACE. This was one of them from 2013 This is excerpted from the Mount Sinai Medical Center ME CFS Symposium November 2013 In it he talks about a study they were doing on PEM, (around 24 minutes in) to disprove PACE, or the use of exercise as a therapy for ME/CFS. What happened to this study. I can't find it? Also in another interview with him another doctor mentions a similar study that was done in Barcelona around that time(?) Also, according to other vids and me-pedia "He is a clinical instructor at The Icahn School of Medicine at Mount Sinai, and, also, leads the CFS Center at Mount Sinai Hospital in New York City." BUT I looked on the school of medicine at Mount Sinai and cannot find any mention of him or research or treatment relating to ME/CFS. In fact their info on the subject is pretty bad: " What Causes It? The cause of CFS is unknown, but a virus or an immune system reaction may be responsible. Preliminary research suggests herpes infection, for example, may trigger CFS. Risk factors include extreme stress or anxiety, flu-like illness that does not completely go away, poor eating habits, and psychological conditions, such as obsessive compulsive disorder, neuroticism, and perfectionism. Depression can make the condition worse and make it last longer." " Lifestyle Get regular exercise. Your doctor may suggest that you see a physical therapist to create an appropriate exercise program. At least one study shows that people with CFS who exercise have fewer symptoms than those who do not exercise." http://www.mountsinai.org/health-library/condition/chronic-fatigue-syndrome I have dug about a bit more and he has his own Youtube channel and regularly trains new medical students about ME/CFS. https://www.youtube.com/user/denlander794 And he now appears to have his own ME and CFS clinic......see FB: https://www.facebook.com/DrEnlander/ clinic website:http://www.enlander.com/ Can anyone shed any light on the study, and apart from becoming semi-retired what happened? eta: have just looked on his clinic website and there its says "Dr Enlander is on the faculty of Mount Sinai Medical School and is an attending physician at Mount Sinai Medical Center New York." so I'm even more confused eta: Jen Brea saw Dr Enlander, think he appears briefly in Unrest.
