Social Sensitivity and Brain Activity in Eating Disorders

Individuals with eating disorders display heightened sensitivity to social threats, often rooted in traumatic backgrounds. They are overly attentive to criticism, avoid positive social cues, and frequently misinterpret intentions as hostile. This behaviour aligns with decreased activity in the ventromedial prefrontal cortex, suggesting difficulties in emotional regulation and coping with social stress.

Linking Traits, Cognition, and Brain Activity to Eating Disorders

Eating disorders stem from specific personality traits, cognitive deficits, and distinct brain patterns. Traits like perfectionism and emotional volatility contribute to impulsivity and other eating disorder behaviours, along with avoidance and limited self-control. Cognitive issues, such as difficulties in task-switching or inhibiting responses, play a role with anorexia and bulimia tied to the former, and binge eating to the latter. Brain activity differs across ED types: anorexia is marked by heightened control, bulimia by impulsivity, and binge eating by habitual behaviour and focus challenges.
