A study conducted by Jacob Kay et al. found that male and female teenagers who reported a history of concussion in the last year were at greater risk of suicidal ideation, planning, and attempts than those who had not sustained a concussion in the previous year.

A paper published in the Journal of Neurotrauma found that children with persistent symptoms had imaging “evidence of ongoing microstructural reorganization or neuroinflammation,” highlighting the importance of delaying a child’s return to play following a concussion if symptoms are persisting.

A study found that very low and very high screen time predicted more severe postconcussion symptoms in the first 30 days post-injury. However, this association was no longer present once patients were more than 30 days out from their injury.
