Integrating Functional Brain Neuroimaging and Developmental Cognitive Neuroscience in Child Psychiatry Research

Abstract 

Objective

To provide an overview of clinical research aiming to develop a mechanistic understanding of brain dysfunction in child psychiatric disorders.

Method

Technological, conceptual, and translational approaches relevant to the investigation of brain function in pediatric psychiatric illnesses are explored. Research in the area of pediatric bipolar disorder is used as a prototypic model illustrating the use of complementary techniques of functional magnetic neuroimaging and neurocognitive studies to identify abnormalities in neural circuitry function.

Results

Studies of bipolar youths indicate impairment in cognitive and affective neural systems and in the interface of these two circuits. This evolving field paves a future pathway for identifying diagnostic biomarkers for the disorder, providing tools for monitoring response to pharmacotherapy, examining illness-associated alterations in developmental trajectory, and facilitating the use of animal research for guiding the development of novel treatment strategies.

Conclusions

Studies of brain function in child psychiatry are establishing a platform of knowledge and methods that offer promise for revolutionizing both models of illness pathophysiology and future diagnostic and therapeutic practice.
