Key Takeaway
Note altered resting-state functional activity in specific brain regions associated with postpartum depression.
This meta-analysis synthesizes data from 475 postpartum depression patients and 504 healthy controls to evaluate resting-state functional imaging patterns. The scope includes analysis of regional brain alterations and associated molecular profiles. No medication interventions or clinical adverse events were assessed in this mechanistic review.
Key synthesized findings include increased resting-state functional activity in the left inferior occipital gyrus and the left precuneus. Conversely, the analysis identified decreased activity in the right amygdala and the left precentral gyrus. Additionally, gene enrichments were observed, specifically involving ion channel function, transmembrane transport, and gated or passive channels.
The authors highlight significant limitations, noting that inconsistent findings persist across resting-state functional imaging studies of regional brain alterations in postpartum depression. Furthermore, connections between these imaging patterns and transcriptional profiles or neurotransmitter systems remain largely uncharacterized. As this is a mechanistic review, causality cannot be inferred, and clinical implications of these findings are not yet established.

BACKGROUND: Inconsistent findings persist across resting-state functional imaging studies of regional brain alterations in postpartum depression (PPD), while connections to transcriptional profiles and neurotransmitter systems remain largely uncharacterized.
METHODS: We performed a whole-brain voxel-wise meta-analysis of resting-state functional imaging studies comparing PPD patients and healthy controls using SDM-PSI software. JuSpace toolbox analyzed atlas-based nuclear imaging-derived neurotransmitter maps, and transcriptional data were sourced from the Allen Human Brain Atlas.
RESULTS: Our systematic review identified 12 functional imaging studies (475 PPD patients, 504 controls). Patients with PPD displayed increased resting-state functional activity in the left inferior occipital gyrus and left precuneus as well as decreased resting-state functional activity in the right amygdala and left precentral gyrus. These functional alterations spatially overlapped with serotonergic, dopaminergic, and VAChT systems. Transcriptional analysis revealed PPD-related gene enrichments in ion channel function (transmembrane transport, gated/passive channels) and channel complexes.
CONCLUSIONS: The meta-analysis revealed functional alterations within the DMN, limbic, and primary sensorimotor systems in PPD patients. These changes were linked to neurotransmitter alterations and genetic modulations underlying brain dysfunction. Collectively, these findings advance mechanistic understanding of PPD pathophysiology.
