Children's Hospital of Philadelphia study shows pre-existing mental health diagnoses in youth prolong concussion recovery and increase emotional burden.

Children's Hospital of Philadelphia researchers found that pre-existing mental health diagnoses in youth contribute to longer recovery times and greater emotional burden after concussion. The study showed a "dose-response" effect: more mental health diagnoses led to increased emotional symptoms and prolonged recovery. Addressing pre-existing mental health diagnoses is crucial for managing concussions and supporting children's recovery.
