Adults with ADHD show higher emotional eating and lower cognitive flexibility in case-control study

This case-control study examined associations between adult ADHD core symptoms, cognitive flexibility, and emotional eating in 76 adults with ADHD and 69 healthy controls. The ADHD group showed significantly higher emotional eating scores (t=5.39, p=0.001) and lower cognitive flexibility scores compared to healthy controls. No specific intervention or exposure was reported, and the study compared ADHD patients to healthy controls without describing the setting or follow-up period.

For emotional eating, measured by EEQ scores, the ADHD group had significantly higher scores with a t-statistic of 5.39 and p-value of 0.001. For cognitive flexibility, measured by CCFQ total score, the ADHD group showed lower scores with a t-statistic of -5.52, though the exact p-value was not reported. The direction of both findings indicates greater emotional eating and reduced cognitive flexibility in the ADHD population.

Safety and tolerability data were not reported in this observational study. The research has several limitations: it cannot establish causation due to its case-control design, effect sizes and absolute numbers were not provided, and key methodological details including setting and follow-up duration were not reported. The study received approval number I11-798-23.

For clinical practice, this evidence suggests potential associations between ADHD symptoms, emotional eating, and cognitive flexibility in adults. However, the observational nature means these findings should not be interpreted as demonstrating causal relationships. Clinicians might consider screening for emotional eating patterns in adult ADHD patients while recognizing these associations require further investigation in prospective studies.
