ASD and Psychosis in Young People: Diagnostic Challenges and Clinical Implications

The clinical intersection of autism spectrum disorder (ASD) and psychosis in young people constitutes one of the most complex domains in modern psychiatry. This narrative-based review aims to delineate the historical background and diagnostic boundaries between these two conditions, particularly given the rising prevalence of ASD and the frequent occurrence of diagnostic overshadowing. By examining the nuanced phenomenological differences—specifically the distinction between autistic “self-talk” and true auditory hallucinations—this paper identifies key differentiators in social communication, reality testing, and functional trajectories. The review concludes that a neuro-affirming, stepwise clinical formulation is essential for reducing diagnostic errors. This approach informs earlier, individualized management strategies, including adapted psychological therapies and cautious pharmacological interventions, to better serve neurodivergent youth in mental health settings.
