ACTIVE RESEARCH PROJECTS
Oxidative Stress and Bipolar Disorder Trajectories (CURRENTLY ENROLLING)
We are studying brain mechanisms related to changes in mood with aging in bipolar disorder. Results of this study may help us find new treatments to improve mood outcomes with aging. This study is funded by the National Institute of Mental Health.
Effect of Biological Sex and Circulating Sex Hormones on Oxidative Stress in Bipolar Disorder (CURRENTLY ENROLLING)
In this study, we are examining sex differences in brain mechanisms related to bipolar disorder. This study is funded by the Brigham & Women’s Hospital Program for Interdisciplinary Neuroscience, Women’s Brain Initiative Pilot.
Linking the roles of HPA-axis response and GABAergic function in women (CURRENTLY ENROLLING)
We are studying the relationship between brain function and stress response in women. This study is funded by the Brigham & Women’s Hospital Connors Center, WHISPR Pilot.
COMPLETED RESEARCH PROJECTS
Neuroimaging biomarkers of lithium response in bipolar disorder
In this study, we used high-resolution 7 Tesla neuroimaging to examine brain features related to response to lithium treatment in bipolar disorder. We found differences in brain activation in prefrontal and limbic regions in response to a fearful faces task in people who responded to lithium compared to people who did not respond. We also identified localized relative atrophy in the CA1 region of the hippocampus in lithium non-responders as compared to responders. These results provide a foundation for future studies to identify brain features that can predict lithium response. This study was funded by the National Institute of Mental Health and the Johns Hopkins Catalyst.
