Sensory over responsivity (SOR) as a transdiagnostic marker of neurodevelopmental risk. An epidemiological birth cohort study

SOR is a prevalent and clinically significant transdiagnostic feature that cuts across multiple neurodevelopmental domains. Our findings support the conceptualization of SOR as a modality-specific liability factor nested within the proposed neurodevelopmental spectrum of the Hierarchical Taxonomy of Psychopathology (HiTOP) framework. Recognizing SOR as a transdiagnostic marker may improve early identification and guide more tailored interventions for children with diverse developmental profiles.
