Concussion Increases Risk of Mental Health Issues in Children

0 2 years ago

Among children and adolescents aged 5-18 years, concussion was associated with a higher risk of mental health problems, compared with age- and sex-matched children and adolescents with an orthopedic injury, according to a cohort study published in JAMA Network Open.

While concussions are one of the most common head injuries in the pediatric population, the extent to which they increase the risk of new onset psychiatric disorders or subsequent psychopathology is unclear, lead author Andrée-Anne Ledoux, PhD, of the Children’s Hospital of Eastern Ontario Research Institute, Ottawa, and colleagues explained.

The researchers conducted a population-based retrospective cohort study to evaluate associations between concussion and risk of subsequent mental health issues, psychiatric hospitalizations, self-harm, or suicides in children and adolescents, with follow-up ranging from 1 month to 10 years.

The data were obtained from province-wide health administrative databases. Participants with concussion were included in an exposed group, while those with an orthopedic injury were included in a 1:2 age- and sex-matched comparison group.


The study cohort comprised 448,803 participants, including 152,321 and 296,482 children and adolescents with concussion and orthopedic injury, respectively.

The incidence rates of any mental health problem were 11,141 per 100,000 person-years in the exposed group and 7,960 per 100,000 person-years in the unexposed group (difference, 3,181; 95% confidence interval, 3,073-3,291 per 100,000 person-years).
