The study is based on information collected from 111 homeless men aged 27 to 81 years old. The men were recruited from a downtown Toronto shelter and interviewed by researchers at St. Michael’s Hospital.
Dr. Jane Topolovec-Vranic, who led the study, said the survey results are important for those who work with homeless populations, as brain injuries are strongly linked with mental health issues, substance abuse, seizures and other complications. Dr. Topolovec-Vranic also said the fact that so many homeless men suffered their injury before taking to the streets, suggests physicians need to keep a closer watch on those who suffer a TBI, as they could be at greater risk of dereliction.
The study -- which was published this week in the journal CMAJ Open -- follows similar findings by Dr. Stephen Hwang of the hospital’s Centre for Research on Inner City Health. Dr. Hwang's larger study looked at more than 1,100 Canadians who were homeless or vulnerably housed in Toronto, Vancouver and Ottowa. He found roughly 61 percent have suffered a TBI, seven times the TBI rate suffered by the general population.
Dr. Hwang's study also found that homeless men and women who had suffered a TBI were more likely to be arrested or incarcerated. Homeless TBI sufferers were also found to have a better chance of becoming a victim of physical assault.
