Mechanisms of attachment and trauma. Clinical and neurobiological considerations for EMDR treatment of eating disorders
Description
Background and aims
This presentation summarizes the results of studies in which fMRI studies were conducted to assess the brain mechanisms involved in processing visual stimuli of food in individuals with eating disorders in order to better target EMDR work with patients with anorexia nervosa, bulimia nervosa, and binge eating disorder.
Methods
A systematic review approach was used, based on the PRISMA guideline. Three databases-Scopus, Pubmed, and Web of Science (WoS)-were searched for correlates of eating disorders in the brain. From an original pool of 688 articles, 28 were selected and reported.
Results
Anorexia nervosa appears to be associated with general hyperactivity in brain regions involved in top-down control, but also in emotional areas such as the amigdala, insula, and hypothalamus. Bulimia nervosa is associated with abnormalities in impulsivity and emotion regulation, resulting in hyperactivity of the insula and right striatum, compared with healthy controls. Finally, the neural correlates of binge-eating disorders appear to be located in brain structures such as the temporal cortex and striatum, linking this condition to the use of dissociative strategies and addictive aspects.
Conclusions
Each eating disorder is characterized by specific activation patterns. Therefore, it is necessary to pay special attention to triggers, targets, and maintenance processes in order to plan effective EMDR interventions.
Abstract topic
eating disorder and neurofunctional correlates.
