Moving toward transdiagnostic dimensional models of neurodiversity and mental health (and away from models of psychopathology).

Abstract

Increasing recognition that neurodiversity is part of human diversity prompts reconsideration of the current dominant conceptualization of neurodivergence as inherently atypical or pathological. We propose a distinction between neurodevelopmental conditions and mental health conditions such that DSM neurodevelopmental disorders should no longer be subsumed under the mental disorder classification but instead reclassified alongside them. At the same time, we also call for more attention to be paid to the mental health and well-being of individuals with neurodevelopmental conditions due to high rates of co-occurring depression, anxiety, substance use, and other mental health concerns. Moving toward transdiagnostic dimensional models of neurodiversity and mental health-rather than dimensional models of psychopathology-embraces neurodiversity as human diversity and destigmatizes neurodivergence. Inclusion of neurodevelopmental conditions in transdiagnostic dimensional models recognizes the high co-occurrence of different neurodevelopmental conditions with each other and with mental health concerns and increases access to appropriate and needed supports to improve well-being across the lifespan.
