Clinical Neuropsychology Within Adolescent and Young-Adult Psychiatry: Conceptualizing Theory and Practice

Abstract

Historically, clinical neuropsychology has made significant contributions to the understanding of brain–behavior relationships, particularly in neurological conditions. During the past several decades, neuropsychology has also become established as an important discipline in psychiatric settings. Cognition is increasingly recognized as being core to psychiatric illnesses and predictive of functional outcomes, augmenting theories regarding symptomatology and illness progression. Adult-type psychiatric disorders (including schizophrenia and other psychotic, mood, anxiety, eating, substance-related, and personality disorders) typically emerge during adolescence or young adulthood, a critical neurodevelopmental period. Clinical neuropsychological assessment in adolescent psychiatric patients is particularly valuable in informing clinical formulation and intervention and can be therapeutic across a number of levels. This article articulates the theoretical considerations and practical challenges and applications of clinical neuropsychology within adolescent and young-adult psychiatry. The importance of considering the neurodevelopmental context and its relationship to current theoretical models underpinning clinical practice are discussed.
