Abstract
Purpose: To investigate the impact of anxiety and depression symptom severity on executive functioning in adults with Attention Deficit Hyperactivity Disorder. Method: Thirty-one adults ranging from 18 to 72 years of age with a confirmed ADHD diagnosis took part in the study. The study was designed as an online experimental survey which used a self-administered mental health questionnaire to evaluate participants’ levels of depression and anxiety and two neuropsychological tests to assess three areas of executive functioning: working memory, flexible thinking, and inhibitory control. Results: Statistical analysis revealed no difference between symptom severity of depression and anxiety on working memory and inhibitory control although a significant difference was found in cognitive flexibility between symptom severity of depression and anxiety. Conclusion: Comorbidity between ADHD, anxiety and depression may impact only specific executive functions in adults.
