"Link Found Between Childhood Maltreatment and Reduced Brain Size"

A neuroimaging study found that toddlers who experienced more severe maltreatment had lower total brain volume, particularly smaller gray matter volume, which was linked to lower cognitive abilities. Childhood maltreatment encompasses physical, emotional, and sexual abuse, as well as neglect, and can have long-lasting effects on mental and physical health. The study, conducted on 86 children aged 3 to 5, suggests that greater maltreatment severity in early childhood is associated with smaller brain size and implications for intellectual ability, emphasizing the need for mechanism-driven targets for early intervention.
