Abstract:
This study investigates sex differences in demographic and injury-related characteristics, along with recovery patterns, in children with mild traumatic brain injury (mTBI) who failed at least one Performance Validity Test (PVT). A retrospective analysis of 186 patients (8–18 years old; 65.1% females) from a specialty concussion clinic with non-credible effort on PVTs was conducted. Data on demographics, injury-related characteristics, symptoms, as well as recovery patterns, were analyzed. There were significant sex differences in age at injury, pre-injury academic status, ADHD prevalence, physical activity levels, and post-injury emotional symptoms. Girls exhibited longer recovery times, had more clinical visits, and received different provider recommendations. This study revealed significant sex differences between boys and girls with mTBI and non-credible effort on PVTs. These findings underscore the need for sex-informed approaches in pediatric mTBI management and highlight areas for future research.
Level of Activity: Introductory
Objectives:
1) Analyze the implications of PVT results in children with mTBI.
2) Assess sex differences in demographic and injury-related characteristics in children with mTBI who failed a PVT.
3) Compare recovery patterns in children with mTBI who failed a PVT.
4) Help guide education and intervention related to pediatric mTBI.
