Current Therapeutic Approach in EDNOS

Abstract

Background and aims:Despite the high prevalence of EDNOS only a small proportion of individuals with this disorder seek treatment, which may be due in part to difficulties in finding specialized treatment settings for EDNOS and the high costs and logistics associated with face-to-face individual psychotherapy. This omission is critical since there is evidence that the severity of psychopathology and degree of secondary psychosocial impairment in those with EDNOS are comparable to those seen in patients with anorexia nervosa (AN) or bulimia nervosa (BN). There has been hardly any research on the treatment of atypical EDs other than the promising effort on BED, for which Cognitive Behavior Therapy (CBT) is proposed to be the most effective treatment. The aim of this presentation is to show several pilot studies and our experience of treating EDNOS cases, but also to analyze variables associated to good-outcome.Method:We performed several clinical studies with EDNOS patients at the University Hospital of Bellvitge to assess the effectiveness and efficiency of specific outpatient CBT programs of short and long term duration.Results and conlusions:The few case-control studies where the effect of diagnosis on the prognosis has been analyzed have shown differential course and outcome in EDs. EDNOS (with exception of BED) showed the poorest long-term prognosis, due to their heterogeneity and, in many cases, to their lower motivation to change. Specific therapy programs, based on our experience, will be discussed.
