Research & Publications


The Neurodevelopmental/Behavioral Imaging Characterization of Adolescent Substance Use Disorders (NICAS) laboratory has established a research program that seeks to improve treatments for adolescent substance use disorders by enhancing our understanding of how treatment response for adolescents with substance use disorders is associated with brain and behavioral changes. This program of research has the potential to inform our understanding of the brain basis of drug addiction and to improve long-term treatment outcomes in adolescents with co-occurring substance use and psychiatric disorders.  

Our laboratory utilizes multimodal neuroimaging (EEG, resting-state, and task-based functional magnetic resonance imaging (fMRI)), behavioral, and epidemiological approaches to characterize individual-, family and social network-, treatment-, and population-level mediators of treatment response for adolescents with substance use disorders and co-occurring psychiatric disorders. Through improved understanding of how substance use and psychiatric symptoms change during treatment at different levels of analysis (biological, behavioral, family/social system, population), we hope to gain a systematic framework for what really influences treatment response, and to utilize these findings to modify existing treatment approaches as a way of enhancing outcomes and for characterizing novel treatment targets.  Furthermore, our studies will provide early understanding about how the brain changes during addiction recovery and will begin to characterize the neurobiological predictors and mechanisms of behavioral change for substance use and co-occurring psychiatric symptoms and disorders in youth (ADHD, Conduct Disorder, Mood and Anxiety Disorders, Trauma-related Disorders).
