Prior Concussions Make Long-Term Disability More Likely After Car Crashes
Have you ever wondered if a prior concussion makes it more likely you will suffer long-term disability after a car crash. A Canadian study states the clear answer is yes. The study involved over 900,000 treated after crashes. The adjusted relative risk of long-term disability was 15% higher in patients with history of prior concussion.
