Attention-deficit/hyperactivity disorder (ADHD) is characterised as a neurodevelopmental disorder marked by impulsivity, hyperactivity, and inattention, frequently seen in young offenders (Silva et al., 2014). The development of delinquent behaviours is significantly influenced by ADHD traits, which arise from adverse childhood experiences, comorbid conditions, and socio-environmental factors (Rutten et al., 2022; Wojciechowski, 2021). This paper explores the relationship between ADHD and juvenile delinquency, emphasizing behavioural, psychological, and social aspects. Methods: A systematic literature review was performed in accordance with PRISMA guidelines, utilizing EBSCO Discovery Service, Science Direct, PubMed, and the snowball method. We analysed studies (n=21) including juvenile offenders diagnosed with ADHD and comparisons with non-offenders or controls without ADHD who met the specified inclusion criteria. The methodological quality of the studies was assessed using the Joanna Briggs Institute's assessment tools. Results: In the reviewed studies, symptoms of ADHD—especially impulsivity and emotional dysregulation—along with conduct disorder, substance abuse, and depression were shown to worsen these behaviours. Additionally, sociodemographic elements like low educational achievement and an adverse family environment played a role in contributing to offending. The findings indicate that ADHD serves as a significant risk factor for juvenile delinquency, interacting in complex ways with behavioural and social influences. The studies highlight the importance of early diagnosis, tailored treatment, and comprehensive rehabilitation programs within the juvenile justice system to mitigate long-term risks and encourage social inclusion.
