Shillong: Treating depression during pregnancy shapes how a baby’s brain grows before birth. A study published in Nature Communications found that MOMCare, a brief interpersonal therapy, benefits both mother and child. Researchers followed 234 pregnant women during their first or second trimesters. They split participants into two groups. The first group received eight 50-minute sessions focused on improving relationships and reducing conflict. The second group received mental health education and community referrals. Everyone maintained standard prenatal medical care.
Previous data showed 36% of participants had depression before the intervention, dropping to 6% after MOMCare. The therapy also helped women carry babies to full term. Doctors used magnetic resonance imaging, or MRI, to scan infants within weeks of birth. They discovered the hippocampus was 5% smaller in babies whose mothers used MOMCare. That brain area handles memory and emotional regulation. Later, researchers tested the infants with a noisy, moving robot. Babies with smaller hippocampal volume reacted with less negativity. This implies faster early brain growth triggered by stress might actually be detrimental.
The study highlights how maternal health affects two generations. One in five women face depression during pregnancy. This condition increases risks for high blood pressure and preterm birth. Experts hope to track these children further to monitor long-term mental health. The authors state, "When a mother receives timely, relationship-focused support like MOMCare, the effects extend beyond her own mood and well-being to shape the very architecture of her baby’s developing brain before birth." Investing in accessible, low-stigma care could fix developmental risks before they start.
