Excellent presentation from Dr Peterson on ME, in Stockholm last month. He talks about how CFS was the wrong name in 80s (in USA), trivialising the illness. He talks about how post-exertional malaise, neurological and immunological abnormalities, and not 'fatigue', are at the forefront of research now (unless you are in the Wessely club in UK). He talks of the importance of definition, the importance of getting it right.
Really excellent, I could cry.
