Abstract

BACKGROUND: Certain factors such as age and gender seem to affect the risk of developing post-concussion syndrome (PCS). We assessed the interactions between age, gender, concussion history and mechanism of injury in PCS patients so that a better understanding could guide the development of targeted prevention strategies.

METHODS: Demographic data including age, gender, concussion mechanism of injury and concussion history were collected from (1) a prospective study evaluating PCS biomarkers and (2) a retrospective chart review of PCS patients. A total of 437 PCS patients who were assessed at the Canadian Concussion Centre or Toronto Western Hospital, Toronto, ON, were included.

RESULTS: Overall, there were more men with PCS; however, a greater percentage of women had PCS after a single concussion. The results showed that age, gender and concussion history are conditionally dependent on the mechanism of injury, and independent of one another. The relative frequency of having PCS was greater in the following instances: (1) being a woman and having had concussion from a fall or motor vehicle collision (MVC), (2) being older and having had concussion from a fall or MVC or (3) having a single concussion with cause being MVC or fall.

CONCLUSION: In patients with PCS, age and gender interact with the mechanism of injury to influence the risk of concussion. Targeted prevention strategies may be essential to prevent injuries leading to PCS.
