A new study from the University of Toronto, titled “Risk of Suicide after a Concussion,” assessed the long-term risk of suicide after concussion. Dr. Michael Fralick and his colleagues performed a longitudinal cohort analysis of adults with the diagnosis of a concussion in Ontario, Canada from April 1, 1992 to March 31, 2012, a 20 year period. Severe cases that resulted in hospitalization were excluded.
