'More than half of criminals may have suffered a head injury which could be fuelling their offending, a new review by British brain experts suggests.
It does seem to matter where the injury occurred. Frontal injuries appear to have more impact on aggression. One of the consquences of head injury is attention-deficit hyperactivity disorder, and studies have shown that treatment for ADHD leads to a reduction in criminality and that's down to reduced aggression. So treating symptoms like that could help. - Professor Seena Fazel
Specialists from the universities of Oxford, Exeter, Manchester, Glasgow and Sheffield, and the Centre for Mental Health, are calling for all prisoners to be routinely checked for signs of traumatic brain injuries.
A comprehensive review, published in The Lancet Psychiatry, suggests that bumps to the head from falls, assaults or road accidents can lead to neural injuries which alter the brain structure, and increase the risk of violence offending.
The authors claim that up to 60 per cent of people in custody have suffered some kind of head injury in the past, ranging from mild to severe.
In contrast, around one in 200 people in the general public have been admitted to hospital for a head injury according to the charity Headway.
The majority of prisoners had suffered some kind of head injury, the review found
The experts say helping prisoners receive proper treatment could prevent future offending and called on schools, doctors and hospitals to help identify youngsters who have suffered head injuries before they commit crime.'
