These symptoms, referred to as post-concussion symptoms (PCS), include headaches, fatigue, sleep disruption, mood and concentration difficulties. They often result...

Generating innovation through the use of common data: Improving the diagnosis and treatment of pediatric and adolescent mild traumatic brain injury in Canada.

2012/13-2017/18 • $766,895 • PI,CO,Other
The incidence of pediatric traumatic brain injury (TBI) in North America is alarmingly high; studies suggest that mild TBI (mTBI) make up 70-80% of all cases reported. Of particular concern is that not only do many post-concussive symptoms, which manifest as cognitive, physical and behavioural...
