Early Life Adversity and Disordered Eating: Cognitive and Neural Mechanisms.

The mosaic brain evolution perspective states that the relative sizes and functions of brain regions adapt to living environments and behavioural motivation. Early life adversity brings changes to brain structure, function, and patterns of cognitive processing of food cues. Specific brain development patterns are associated with subsequent disordered eating, which, on the one hand, increases the risk of obesity and metabolic syndrome, and, on the other hand, leads to mental health problems, such as depression and anxiety. This review intends to synthesise aberrant brain development indices, describe aberrant brain developmental trajectories, summarise aberrant neural markers of cognitive processing of food cues, conclude how early life adversity affects disordered eating through aberrant brain development patterns, and provide neural implications for future disordered eating research and intervention.
