Case Report: Physiological and psychological underpinnings of muscle dysmorphia using EEG, GSR, and eye-tracking.

ABSTRACT:

Background

Muscle dysmorphia (MD), a subtype of Body Dysmorphic Disorder (BDD), involves an obsessive preoccupation with perceived insufficient muscularity despite an objectively muscular physique. While its psychological features are well-documented, physiological and attentional underpinnings remain underexplored.
