Unveiling Maternal-fetal BRAin-body Interactions in Pregnant WOmen Affected by Depression (BRAWO)
The goal of this study is to learn how depression during pregnancy is linked to changes in the brain and body of the mother and to the development of the baby, in pregnant women with major depressive disorder (MDD) and pregnant women without depression.
The main questions it aims to answer are:
- How common is major depressive disorder during pregnancy in a European multi-site cohort?
- Do pregnant women with MDD show differences in hippocampal volume compared with pregnant women without depression?
- Do maternal blood, placenta, cord blood, brain imaging and heart activity measures, and the brain and development of the babies, differ between the two groups?
Pregnant women will be screened within the 20th week of pregnancy and assigned to the MDD group or to the control group based on a structured clinical interview. They will not receive any study drug: women with depression will receive the usual care recommended by clinical guidelines.
Participants will:
- Have clinical, psychiatric and psychological assessments (interviews and questionnaires) at screening, at 22, 26 and 32 weeks of pregnancy, at birth, and at 1 and 6 months after birth
- Have a brain MRI with simultaneous EEG-ECG or photoplethysmography (PPG) at about 22 weeks of pregnancy
- Have a fetal MRI by 22 weeks and fetal ultrasound scans at 22, 26 and 32 weeks
- Give blood samples at 22, 26 and 32 weeks of pregnancy, and a cord blood sample at birth (placenta samples in a subgroup at the Milan center only)
Their newborns will have a neurological and visual examination, a brain MRI and an EEG-ECG or PPG recording after birth, and a developmental assessment (Bayley Scales) at 6 months.

Detailní popis
BRAWO is a non-pharmacological, international, multicenter, non-profit study conducted in Italy (Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, coordinating center), Spain (Institute of Biomedicine of Seville, IBiS) and Germany (Philipps University Marburg). It implements Work Package 3 of the BRAWO research project, funded under the ERA-NET NEURON Joint Transnational Call 2024 "Bidirectional brain-body interactions".
The study is classified as interventional because it includes procedures that are not part of standard clinical care (maternal, fetal and neonatal MRI, EEG-ECG/PPG recordings, biological sampling). These procedures are non-invasive or minimally invasive. No investigational medicinal product is tested; women with MDD receive standard care, which may include SSRI antidepressants.
Groups:
- Group 1: pregnant women with MDD diagnosed with the SCID-5-CV at screening
- Group 2: pregnant women without current or past psychiatric disorders
- Newborns of enrolled women, enrolled at birth after consent from both parents
Visits: V0 screening (within 20 gestational weeks, GW), V1 (by 22 GW), V2 (26 GW), V3 (32 GW), V4 (birth), V5 (1 month postpartum), V6 (6 months postpartum).
Maternal clinical assessments include clinician-rated scales (Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Global Assessment of Functioning) and self-rated questionnaires (EPDS, STAI Y1-2, SCL-90-R, CES-D); bonding, couple and family scales (MPAS, PBQ, ECR-R, RQI, DAS, FES, PSI-SF) are administered at 1 and 6 months postpartum.
Biological samples: maternal plasma at V1, V2 and V3, umbilical venous cord blood at birth, and placental tissue (elective cesarean deliveries, about 10 participants per group, Milan only). Proteomic analyses (LC-MS/MS) are centralized in Milan; placental samples also undergo RNA sequencing and histological analyses. With specific consent, residual samples are stored in the Policlinico biobank.
Neuroimaging and electrophysiology: maternal multimodal MRI (structural, diffusion, task and resting-state functional MRI) with simultaneous EEG-ECG (Milan) or ECG/PPG (Seville, Marburg); fetal MRI; neonatal MRI and EEG-ECG/PPG at 40+0 to 43+6 weeks of gestational age. Data are harmonized across sites (e.g., ComBat).
Sample size: a screening target of 600 pregnant women was calculated to estimate MDD prevalence (expected 15%, precision ±3.42%, 95% confidence level, 30% dropout). At least 60 women per group completing follow-up to 6 months postpartum provide >90% power to detect hippocampal volume differences (two-sample t-test, alpha 0.05). In total, 600 pregnant women and 120 newborns are expected to be enrolled. An interim analysis of dropout rate and data quality is planned at about half of enrollment.
Pre-collected data from a previous study at the coordinating center (MINI protocol) and publicly available data from the developing Human Connectome Project (dHCP) will be used to train multivariate, machine learning and dynamical systems models, which will be tested on BRAWO data to predict maternal and infant outcomes at 6 months.
Data are collected in REDCap and imaging data in XNAT.
