Objectives: Attention deficit hyperactivity disorder (ADHD) is a lifelong neurodevelopmental disorder in which there are significant problems of attention, hyperactivity and impulsive acts. There are some pervasive behavioral, cognitive, and emotional traits in antisocial personality disorder (ASD) such as low frustration threshold, impulsivity, and disregard for others. The aim of this study was to research the prevalence of ADHD in ASD patients.
Method: Forty patients from an outpatient psychiatry clinic, diagnosed with ASD according to structured clinical interview for DSM-III-R personality disorders (SCID-II), were included in the study. Wender Utah Rating Scale (WURS) was applied for the assessment of childhood ADHD. Patients who got high scores in WURS were assessed with Adult ADD/ADHD DSM-IV Based Diagnostic Screening and Rating Scale (Adult ADHD Scale).
Results: DEHB comorbidity in the ASD group was 40% (n=16). Mean inattention and hyperactivity-impulsivity scores were 21.4±9.6 and 19.4±8.7, respectively, in the comorbid group.
Discussion: Our study showed the high prevalence of ADHD in ASD patients. Clinicians should be aware of ADHD comorbidity in the assessment and treatment of ASD patients.
