Decoding the link between substance dependence and attention deficit hyperactivity disorder in adults: A cross-sectional study from North India.

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) and Substance dependence are often thought to be linked as they are found to co-exist in many individuals. ADHD is estimated to be an essential indicator for the development of substance use disorder. Aim and

Objective

To explore the relationship between different substance dependence and ADHD.

METHODS AND MATERIALS: This cross-sectional single-interview study was done at a tertiary care hospital in which a total of 153 Cases presenting to the Psychiatry OPD in a period of 03 months were selected serially based on inclusion and exclusion criteria. The diagnosis of substance dependence was made as per ICD-10 criteria. These subjects were then evaluated for the presence of ADHD and physical and psychological symptoms using the Adult ADHD self-rating scale and Maudsley's Addiction Profile.

RESULTS

The majority of our study subjects were aged between 24-29 years (45%) and were predominantly males (98.7%). Most of our subjects were dependent on smack (adulterated heroin) (38.5%) followed by cannabis (27.4%) and alcohol (18.3%). When evaluated for ADHD using the ADHD self-rating scale, we found that almost one-third of the study population had ADHD (33%). Prevalence of ADHD was maximum in the subjects with cannabis dependence (47.6%) followed by tobacco/smoking (38.8%), cocaine (33%), and alcohol (21.5%). This association was statistically significant for cannabis (p = 0.035). The standard mean of both the physical as well as psychological symptoms experienced by subjects was higher in the ADHD group compared to the non-ADHD group which was statistically significant (p < 0.05).

CONCLUSION

While managing patients with substance dependence we need to target both underlying ADHD and any co-morbid physical and psychological illness if present for holistic recovery of the patient.
