Research Interests:

Bipolar disorder (BD) is a neuropsychiatric illness in which people experience episodes of depression and episodes of abnormally elevated mood and energy, referred to as manic episodes. BD affects over 10 million Americans. Most affected individuals respond well to treatment, have relatively few mood episodes, and function well in their day-to-day lives. However, approximately one-third do not. These individuals have a deteriorating course with increasingly frequent mood episodes, treatment refractoriness, and high rates of disability. My research program is dedicated to identifying factors that promote good clinical outcomes in people with BD, and understanding how they interact with the neurobiological substrate of BD to influence brain illness severity. Current research projects include:

1) Investigating biological and clinical factors that enable the early and accurate diagnosis of BD. This is critical because early diagnosis and early optimization of treatment are among the strongest predictors of good clinical outcomes. Unfortunately, over 60% of people with BD are initially misdiagnosed, and they frequently go 6-10 years before receiving the correct diagnosis. We are currently investigating whether a proteomic assay which measures the serum levels of 18 blood proteins can correctly distinguish between bipolar disorder and related psychiatric illnesses in people who present for psychiatric care. We also use causal discovery modelling to investigate symptom networks in mania and bipolar depression to better understand the phenotype of BD.

2) Investigating cardiovascular risk factors (CVRFs) as predictors of psychiatric illness course and brain health in BD. CVRFs such as obesity and smoking are the strongest determinants of morbidity and mortality worldwide. There is growing awareness that they negatively impact brain health and hasten the onset and progression of neuropsychiatric illnesses. We previously found that the structural and chemical brain changes characteristic of BD were more pronounced in obese BD patients than normal-weight BD patients, and progressed more rapidly in patients who experienced additional weight gain. These studies suggested a potential neurobiological explanation for the link between CVRFs and a worse clinical illness course. We are currently using magnetic resonance brain imaging to investigate whether the brain changes characteristic of BD are also more pronounced in BD smokers than BD non-smokers. Taken together, these studies will lay the theoretical groundwork to support planned investigations of whether weight loss and smoking cessation interventions improve clinical outcomes and slow brain illness progression in BD.
