	Abstract

ADHD and learning disabilities (LD) frequently coexist and there are indications that comorbidity may increase the risk of psychopathology. The current study examined the gender distribution and frequency of comorbidity and its impact on the prevalence of symptoms of anxiety, depression, and aggression in a clinic sample of 80 adults with ADHD, aged 18 to 58 years. More individuals were diagnosed with ADHD+LD than ADHD only, with no difference in this distribution according to gender. A factorial multivariate analysis of variance indicated that females with ADHD+LD displayed more cognitive depression than females with ADHD only and than males with ADHD+LD and ADHD only. However, individuals with ADHD only and individuals with ADHD+LD did not differ on overall anxiety, depression or aggression. Likewise, males and females did not differ on measures of psychopathology. This study lays the foundation for continued research into the characteristics and comorbidities of adults with ADHD.
