Developmental Coordination Disorder Plus Oculomotor and Visuospatial Impairment as Neurodevelopmental Heralds of Psychosis Proneness.

Aiming at preventing transitions to more severe psychopathology and boosted by the availability of operational criteria to identify help-seeking subjects at increased risk for psychosis, research into the early prodromal phases of psychosis is attracting a growing clinical interest. Furthermore, the focus of early detection is gradually shifting from prodromal syndromes to the premorbid period. Although mainly driven by clinical-pragatic aims, such a shift is coherent with the neurodevelopmental hypothesis of schizophrenia that might offer a unifying, developmentally informed conceptual framework for early detection. Psychotic experiences, indeed, while overtly manifested in adolescence/early-adulthood, are often antedated by subtle expressions of biological vulnerability already presenting in the early years of life and indexing a putatively altered neurodevelopmental process. Concretely, unspecific premorbid symptoms that may be present since infancy and childhood may lead to early clinical consultancy in child-adolescent mental health services, which could be considered the primary clinical setting to implement early detection. We herewith present a clinical vignette of a child with severe Developmental Coordination Disorder presenting an Attenuated Psychosis Syndrome. The vignette illustrates the intertwining between possible early neurodevelopmental disorders and clinical psychosis proneness in childhood.
