Multimodal Biomarkers and Precision TMS for Postpartum Depression

In the researchers' words

The purpose of this study is to identify multimodal biological markers associated with postpartum depression (PPD) and to evaluate the effectiveness of precision brain stimulation treatment. PPD is a common mental health condition after childbirth that can affect maternal well-being and early child development. Current identification of PPD relies largely on clinical assessments and screening questionnaires, which may not fully capture underlying biological changes. This study uses brain activity, cardiac signals, blood-based biomarkers, interoceptive assessments, and clinical measures to characterize multimodal biological profiles associated with PPD and treatment response. The main questions it aims to answer are: * What multimodal biological differences exist between women with diagnosed PPD and healthy comparison groups, including postpartum and non-postpartum controls? * Which biological or psychological markers can predict whether a patient will respond well to repetitive transcranial magnetic stimulation (rTMS) treatment? * Can a clinical model be created to help doctors choose the best treatment based on these markers? The study focuses on characterizing multimodal biological differences in women with diagnosed PPD and examining clinical response profiles following rTMS treatment, rather than predicting the onset of PPD in the general population. Participants will:…
