Does Gender Matter? Differences in Social-Emotional Behavior Among Infants and Toddlers Before and After Mild Traumatic Brain Injury: A Preliminary Study

Traumatic brain injury is a common cause of acquired disability in childhood. While much is known about cognitive sequelae of brain trauma, gender-specific social-emotional problems in children with mild traumatic brain injury is far less understood. The aims of the study were to investigate gender differences in social-emotional behavior before and after mild traumatic brain injury. Thirty-five 3- to 65-month-old children with mild traumatic brain injury and 70 controls were assessed with Ages and Stages Questionnaires: Social-Emotional. Nine months later, 27 of 35 patients and 54 of 70 controls were reassessed. We found that before injury, boys had more self-regulation and autonomy difficulties and girls had problems with adaptive functioning. Nine months after injury, boys continued to struggle with self-regulation and autonomy and new difficulties with interaction had emerged, whereas in girls, problems in interaction had evolved. Even mild traumatic brain injury in early childhood disrupts normal social-emotional development having especially devastating influence on interaction skills.
