Spiniello G., Sapuppo W. (2022). The comorbidity between Feeding and Eating Disorders and Personality Disorders: A systematic review of current status. IJEDO


Purpose of review: to update the state of art about the comorbidity between Feeding and Eating Disorders (FEDs) and Personality Disorders (PDs), referring to the categorical of the latest versions of the Statistical and Diagnostic Manual of Mental Disorders (DSM): DSM-IV, DSM-IV-TR and DSM-5. The following state-of-art literature review has been carried out since 2014, to which is possible to trace the latest findings about the topic.
Methods: the present systematic review has been conducted in accordance to PRISMA guidelines. Advanced systematic searches in PubMed and EBSCOhost have been conducted using the following search string with Boolean operators (eating disorders or anorexia or bulimia or binge eating) AND personality disorder AND (comorbidity or comorbidities or cooccurrence or comorbid) NOT (review of literature or literature review or meta-analysis or systematic review). The search strategy garnered four studies for inclusion in the present review, referred between February 2014 and March 2022.
Results: the analysis of the 4 studies suggests a comorbidity between FEDs and PDs. While this co-occurrence seems to prevail in a plain population, pre-existence of psychiatric disorders such as ADHD or ASD seem not to have an impact on the comorbidity between the two disorders.
Discussion: more in-depth studies on the general co-occurrence between FEDs and PDs can be really helpful to update and synthesise the results on this sketchy topic, not only for the purpose to bring up to date the literature, but also to be ready to treat such disorders that are constantly evolving.
