SPIEGEL: In an interview with the Frankfurter Allgemeine Zeitung (FAZ), the general secretary of the German Society for Neurodegenerative Diseases (DGN), Peter Berlit, said it's also about the so-called biopsychosocial model. According to this established concept, illnesses are influenced by biological, psychological, and social factors, and all three areas must be considered for successful therapy. Do you disagree with that?
Grande: Regarding the biopsychosocial model of ME/CFS, as a psychotherapist, I would say this: If doctors and scientists focused on biological factors and government agencies and health insurance companies ensured that social factors were less devastating, there would be very little left for my profession.
