Research at the University of Oxford and the Karolinska Institute in Stockholm, based on Swedish medical records for over two million people between 1969 and 2009, indicates that brain injury can treble the risk of premature mortality.
Statistically, only 0.2% of people without an earlier brain injury tend to die prematurely (before the age of 56). The premature-death rate can be three times higher in patients who have suffered traumatic brain injury previously. The situation is worse for people with a psychiatric disorder, for whom the rate of premature mortality rises to 4%.
The main reason is thought to be that traumatic brain injuries cause lasting neurological damage which can impair people’s judgement and their ability to adjust to new challenging situations.
