Undiagnosed ADHD Among Arrested Individuals in London: A Study's Findings
12/12/2025, 10:26:00 PM
Overview of the Study
A recent study conducted by researchers at the University of Cambridge has revealed that approximately half of individuals arrested in London may have undiagnosed attention-deficit hyperactivity disorder (ADHD). The research, published in the journal *Criminal Behaviour and Mental Health*, involved voluntary screenings for ADHD and autism at six Metropolitan Police custody centers over an eight-week period in 2024. Out of 303 individuals offered screening, 71% consented, highlighting a significant potential for identifying neurodivergent individuals within the criminal justice system.
Key Findings
The study found that 50% of those screened scored high enough to warrant further assessment for ADHD, while 5.4% showed signs of possible undiagnosed autism. This prevalence is notably higher than the estimated 5% for ADHD and 3% for autism in the general population. Among those arrested, 60% were detained for drug offenses, with many having existing diagnoses or positive screenings for ADHD. This suggests a potential link between neurodivergence and self-medication with illegal substances.
Implications for the Criminal Justice System
Dr. Tanya Procyshyn, a research associate at the Autism Research Centre, emphasized the importance of understanding how neurodivergence affects interactions with law enforcement. She stated, “To ensure fair treatment in the criminal justice system, we need to understand how neurodivergence affects interactions with the law.” The study advocates for early identification of neurodivergent traits to prevent the criminalization of misunderstood behaviors and to facilitate access to appropriate support.
Dion Brown, a senior detective from the Metropolitan Police Service, noted that early screening could help officers interpret behaviors that might otherwise be misunderstood, creating opportunities to divert vulnerable individuals away from the criminal justice process and towards necessary assistance.
Criticism & Opposition
While the study presents compelling evidence for the need for neurodivergence screening, some critics argue that the focus on ADHD and autism may overlook other underlying issues contributing to criminal behavior. Additionally, concerns have been raised about the potential for overdiagnosis in vulnerable populations, as highlighted by Wes Streeting's call for an independent review into mental health services.

Conclusion
The findings from this study underscore the critical need for neurodivergence screening within the criminal justice system. By identifying individuals with undiagnosed ADHD and autism, law enforcement can better understand the behaviors of those they encounter, potentially leading to fairer treatment and improved outcomes for vulnerable populations. The research advocates for systemic changes that could enhance the support available to individuals with neurodevelopmental disorders, ultimately contributing to a more equitable justice system.
