Maternal Mental Health in the Perinatal Period
Summary
Maternal mental health in the perinatal period addresses the psychological wellbeing of women from conception through the first year after birth. During this time, hormonal fluctuations, sleep disruption and role transition interact with social and economic pressures to influence risk of depression, anxiety and stress. Unrecognised or untreated perinatal mental disorders can undermine maternal–infant bonding, impede child development and have long-term consequences for maternal health. Research spans neurobiological studies of pregnancy-induced brain changes, trials of culturally adapted psychological interventions, large-scale epidemiological investigations of reproductive history in cardiovascular risk and policy analyses of parental leave. Improved screening, early psychosocial support and equitable access to evidence-based therapies are critical for reducing the global burden of perinatal mental disorders.
Research from Nature Portfolio
A longitudinal neuroimaging study tracked changes in cortical volume among first-time mothers during late pregnancy and early postpartum, comparing them with nulliparous women. Across functional brain networks, maternal cortical volume decreased during pregnancy and began to recover in the early postpartum period. Notably, regions within the default mode and frontoparietal networks showed delayed volume restoration, and trajectories differed according to mode of delivery. These findings reveal a dynamic pattern of neuroplasticity in the peripartum brain that may underpin emotional adaptation and cognitive shifts associated with motherhood.

Technical terms
Perinatal period: The time encompassing pregnancy and up to one year after childbirth.
Neuroplasticity: The capacity of the brain to reorganise its structure and function in response to experience or physiological change.
