“…Regarding the course of the disorders, BN and BED are rather variable inter-and intra-individually and reveal higher rates of (spontaneous and treatment supported) remission rates (World Health Organization, 2018) than the other disorders mentioned. The experienced overcompleteness in BID, as well as the course of AN, BDD and MD usually are chronic untreated, and even with psychological treatment, still most of the patients do not reach remission (First and Fisher, 2011;Hartmann et al, 2013;Krebs et al, 2017;Waldorf et al, 2019a;Underwood and Olivardia, 2022). For BID the situation is even worse as there are currently no effective (non-invasive) treatments leading to a remission or cure of BID (Chakraborty et al, 2021), despite several suggestions (e.g., Ramachandran and McGeoch, 2007;Lenggenhager et al, 2014).…”
