DEGAM is the "German Society for General Practice and Family Medicine". In the past, DEGAM has published a guideline about "tiredness". Patients and some doctors took up their voice and wrote to Degam about their contents about CFS. There was some anger due to an ME patient organisation's behavior who agreed to the guideline. There seems to be a connection between this organisation and BPS people. In December 2017 a new guideline is to be published. Patient organisations, again, argued that ME/"CFS" is not tiredness and not a psychological disorder. Here is a short version: http://www.awmf.org/uploads/tx_szleitlinien/053-002k_S3_Muedigkeit_2011-abgelaufen.pdf Again, there is a focus on psychological history, and it is advised not to concentrate too much on diagnostic tests for the danger the patient may be "fixed" on a somatic cause, not a psychological one.
