Prevalence of Adult ADHD Co-morbidity in Alcohol Use Disorders in a General Hospital Setup

BACKGROUND: Attention deficit hyperactive disorder (ADHD) symptoms persisting into adulthood can influence the course and outcome of alcohol use disorders (AUDs). A cross-sectional study was conducted to assess the prevalence of adult ADHD in patients admitted with AUDs in a general hospital setup. METHODS: In this study, 100 consecutive inpatients with alcohol use disorder (AUD) were evaluated for the diagnosis of ADHD. Patients with AUD were assessed with Severity of Alcohol Dependence Questionnaire, Clinical Institute Withdrawal Assessment for Alcohol and Adult ADHD Self Report Scale. Among the subjects who screened positive for adult ADHD on ASRS, diagnosis of adult ADHD was confirmed using the DSM 5 diagnostic interview. Epi-Info Version 7.2 was used for data entry and analysis. Mann Whitney test and Chi-square test (or Fisher's Exact test) were used for statistical analysis. RESULTS: Twenty-one subjects screened positive for adult ADHD. Among them, 19 subjects had a confirmative diagnosis of adult ADHD. Patients with adult ADHD comorbid with AUDs showed accelerated progression towards dependence, and early relapses. CONCLUSIONS: In all, 19% of treatment-seeking inpatients with AUDs have co-morbid adult ADHD. Regular screening of AUD patients for adult ADHD and addressing the psychopathology may improve the treatment outcome.
