Animal Models of Neuropsychiatric Disorders

A B P Fernando et al. Annu Rev Clin Psychol.

Abstract

We survey the utility of animal models of mental illness, based on the identification of possible neurocognitive or neurobehavioral endophenotypes. Three broad clusters of neuropsychiatric disorder are discussed: (a) impulsive-compulsive syndromes, comprising drug addiction, attention deficit/hyperactivity disorder, gambling, obsessive-compulsive disorder, and compulsive eating; (b) disorders at the cognitive-emotional interface, comprising anxiety, depression, and schizophrenia; and (c) disorders purely of cognition, which contribute to the third cluster, cognitive disorders. The emphasis is thus on modeling symptoms rather than disorders per se. We also distinguish between two main aspects of any validated model: the precise neurobehavioral or neurocognitive processes implicated from detailed study of the clinical phenotype, and the perturbations, whether typically genetic, environmental, pharmacological, or neurodevelopmental, that are designed to simulate relevant neural, neurochemical, or molecular aspects of particular neuropsychiatric disorders.
