Low cognitive score 'indicates greater risk of brain injury'

13 March 2013

People with low cognitive function are significantly more likely to suffer from mild traumatic brain injury, according to a new study.

Research published in the British Journal of Medicine suggests that young men are most at risk of suffering traumatic brain injury, which affects ten million people a year worldwide.

The study was carried out by experts at Umea University in Sweden, who analysed cognitive tests undertaken by 300,000 young men with an average follow-up of 19 years.

The experts found that cognitive function was 5.6 per cent lower in those who experienced mild traumatic brain injury in the two years before cognitive testing, and 15 per cent lower in those who suffered at least two mild traumatic brain injuries after cognitive testing.

"Successful prevention of mild traumatic brain injuries may include an assessment and evaluation of these risk factors," the experts stated.

According to the specialists, further studies will help to support the findings and boost the understanding of the outcome impact of traumatic brain injury.
