CLARIFICATION: This article originally stated that Chronic Fatigue Syndrome (ME) is not actually a chronic illness. In fact, the University of Oxford study reported that Graded Exercise Therapy (GET) and Cognitive Behavioural Therapy (CBT) can alleviate symptoms of the condition but did not say that it was not chronic. We are happy to make this clear, and the article has been amended. The ME Association opposes GET on the basis that it can exacerbate symptoms, and says that the use of CBT as a primary treatment strategy is based on the flawed belief that ME/CFS is a psychological problem.
