Association between maternal history of mental illness and neurodevelopment of children during the first 3 years: The Japan Environment and Children's Study

Our findings indicate that children born to mothers with a history of mental illness may exhibit early neurodevelopmental delays in gross motor skills and problem-solving as early as age 1 year, potentially leading to broader neurodevelopmental impairments observed in later childhood. Additionally, childcare support aimed at enhancing neurodevelopment may be essential for mothers with a history of mental illness within the first year postpartum.
