According to a new study, it has been found out that adults who have concussions are almost three times more likely to think of suicide if the injury occurred on a weekday and are at four times greater risk if the injury occurred on a weekend.

The researchers from University of Toronto said that the risk of suicide increased with each concussion a person sustained. The researchers also said that the risk increased even after considering all the other demographics factors of the person.

A researcher and physician at Sunnybrook Research Institute, Donald Redelmeier in a press release said, “We know that a concussion can cause lasting changes in the brain that can alter mood, perhaps resulting in behaviour changes including impulsivity. It’s possible that we’re seeing greater suicide risk linked to weekend concussions due to risk-taking associated with recreation or misadventure, whereas weekday injuries may be linked to employment hazards. We may also be seeing an effect of self-blame if the injury event was self-initiated.”

In order to reach the findings, the researchers analysed medical records of around 235,110 patients with concussions who were diagnosed in Ontario between the year 1992 and 2012.

After thorough evaluation, the researchers found out that there were instances of around 667 suicides during a median follow-up period of 9.3 years which amounts to around 31 people out of 100,000 per year. The researchers said that this suicide rate was even higher than the overall population.

Commenting on the findings of the research, Redelmeier said, “Understanding how a history of concussion raises the risk of suicide, and supporting patients with better screening, treatment and follow-up for recovery may be important steps in preventing these tragic and avoidable deaths.”

The findings of the study were published in the Canadian Medical Association Journal.
