Brain injuries are the most frequent cause of death and disability in children. Studies have shown that brain injuries can cause mental, psychological, social, and behavioural problems. Even mild injuries, such as concussions, have the potential to cause lasting problems in children because of subtle changes to the way the brain works.  Unfortunately, our ability to accurately predict their consequences is limited.  This is likely because the clinical tools that are currently used in hospitals to detect the presence of injuries inside the brain are not powerful enough to identify small bleeds typical of mild brain injury. There now exist new brain imaging tools that have been shown to be accurate at detecting subtle brain changes.  However, we do not yet know how they are associated with children's recovery and functioning.

In this study, children and teenagers with mild brain injuries will be assessed using innovative brain imaging techniques and we will count how many lesions we can see in their brain and measure their size. We will then determine if there is a link between these injuries and children's symptoms and quality of life one and three months after their accident. We will also compare the predictive ability of these techniques to clinical tools that we currently use to estimate recovery in children with brain injury.  The results will have a significant impact on imaging decisions made in emergency departments to diagnose and manage mild brain injuries. 

Our findings also have the potential to improve the identification of children at-risk for having problems after their brain injury and help us orient them and their families to the appropriate resources and services to better their functioning.
