Depression and self-injury are common problems that frequently emerge during the adolescent period. Adolescence is a critical time development during which there are significant changes in behavior and in refinement of neural circuitry. My program of research aims to better understand the aberrant neural processes underlying the onset and maintenance of depression and self-injury in adolescence, and how these abnormalities may change over time and in response to interventions. Current projects include:
(1) Examining developmental trajectories of three neural/behavioral systems as defined by the Research Domains Criteria (RDoC) initiative (Sustained Threat, Self-Knowledge, Cognitive Control) using multiple levels of analysis (brain imaging, cognitive testing, cortisol measurements, self-report) in adolescents with and without non-suicidal self-injury (NSSI). This NIMH-funded R01 has an administrative supplement in Computational Psychiatry to support work applying Bayesian modeling to examine decision-making patterns in adolescents with NSSI, and how this index relates to clinical and neurobiological trajectories.
(2) Exploring efficacy and potential neural mechanisms of intravenous ketamine as a treatment for adolescent depression. We completed 13 adolescent subjects in a protocol that involved 6 infusions of ketamine. Analyses of clinical, neuroimaging and cellular energetics data are underway. Cellular/molecular studies are being conducted by collaborator Susannah Tye at the Mayo Clinic.
(3) Exploring efficacy and potential neural mechanisms of transcranial magnetic stimulation (TMS) as a treatment for adolescent depression. This study involves multi-modal brain imaging and cognitive testing before and after 30 sessions of deep TMS in adolescents with treatment-resistant depression,
(4) Examining neural circuits in adolescents with depression using ultra-high fields (7T).
(5) Examining the links between mitochondrial functioning, inflammation and brain network integrity in adolescents with mood disorders. This is a collaboration with Ana Andreazza at the University of Toronto and Bonnie Klimes-Dougan in the department of Psychology, UMN.
