The overlap between intellectual disability (ID) and criminal justice presents the need to develop a dedicated developmental approach to tackle the particular vulnerability of neurodiverse criminals. The study will offer a reformulated Life-Course Developmental Model that was identified to offer particular trajectories of antisocial behavior among the intellectual disability population. The investigation of the interaction between neurodevelopmental underpinnings and systemic marginalization proves that the life-course persistent pathway is much more prevalent among individuals with intellectual disability than among the overall population. One of the key findings of this study is that a strong association between Early-onset ADHD and access to forensic services was discovered, which implies that cognitive deficiency serves as a principal criminogenic motivator. Moreover, the findings indicate an extensive physiological effect: people who follow a sustained antisocial career trajectory show evidence of a reduction in biological aging and increased vulnerability to chronic disability at middle adulthood. It indicates that in the case of an intellectually disabled person, antisocial behavior is not just a social deviation, but a precursor of devastating health deterioration in the long run. The research questions the existing punitive legal systems by saying that the traditional maturity differentiation is usually irreversible instead of temporary among this generation, and therefore, the reactive sentencing is not effective. The study finally makes the conclusion that there is a need to move towards habilitative justice. The criminal justice system can shift the marginalization to proper reintegration in society by focusing on early specialist intervention, safeguarding by multi-agencies, and prosocial coping measures. The study is crucial in giving a roadmap to be used by legal and clinical practitioners to comprehend the onset, the course, and the cessation of offending via a lifetime perspective, with social justice being given to individuals with intellectual disability.
