Police officers are more than twice as likely to have traumatic brain injuries compared to the general population. Officers who incur these injuries while on duty face more than double the risk of developing complex post-traumatic stress disorder (PTSD). That's according to a new survey-based study from the University of Exeter, published in The Journal of Head Trauma Rehabilitation , which found a connection between traumatic brain injuries and PTSD in police officers.
The study is titled "Co-occurrence of Traumatic Brain Injury and Post-Traumatic Stress Disorder in a National Sample of UK Police Officers: Impact on Social Well-being and Employment Outcomes." Authors say the findings raise concerns over the long-term effects on officers' personal and professional lives and highlight the need for better action and support for officers who have sustained a head trauma in the workplace. Professor Stan Gilmour has 30 years' experience in law enforcement and received The King's Police Medal for his service.
He is now a Senior Research Fellow at the University of Exeter and co-convenor of the Global Law Enforcement and Public Health Association's Neurodisability Special Interest Group. Stan said, "Police officers are exposed to high-stress situations, physical confrontations, and the possibility of injury every day. Adding to that, the increased risk of traumatic brain injuries and PTSD only compounds the challenges officers already face, and this study highlights the urgent need for better monitoring of head injuries and their long-term effects.
" The study surveyed 617 currently serving frontline police officers from England, Scotland, and Wales and found 38% had sustained at least one traumatic brain injury—defined as an injury to the head that caused someone to lose consciousness, or develop symptoms such as confusion, disorientation, or memory loss. This is compared to the rate of 12% found in the general population. Of those officers, 61% report they had experienced these types of injuries on multiple occasions.
Researchers found police officers who reported a history of multiple traumatic brain injuries were more than twice as likely to meet the criteria for complex PTSD—which has similar symptoms to PTSD, but may also include feelings of worthlessness, shame and guilt, problems controlling emotions, and relationship issues. In the study, 22% of respondents had sustained traumatic brain injuries during their policing duties and these officers were more than twice as likely to develop probable complex PTSD. The results found police officers with a history of multiple traumatic brain injuries also face more severe difficulties in their daily lives, including their ability to perform work duties, maintain relationships, and carry out other important activities like parenting.
They also reported physical and cognitive symptoms at a more severe level, including headaches, fatigue, sleep disturbances, and concentration problems. The study calls for assessments for traumatic brain injuries and related symptoms during routine occupational health checks, with targeted interventions for officers who experience both a traumatic brain injury and PTSD. Nick Smith, lead researcher and Postdoctoral Research Associate at the University of Exeter, said, "Our findings highlight a critical gap in support for police officers who suffer traumatic brain injuries and PTSD.
Many officers are grappling with the lingering effects from past injuries while simultaneously managing PTSD symptoms and this creates a double burden that can significantly impair their ability to work, have healthy relationships, and overall quality of life. "Early action and support are essential to prevent long-term consequences and improve outcomes for these officers. For example, police forces could emulate concussion guidelines in sport by developing traumatic brain injury assessments and graduated return-to-duty protocols, which are crucial to reduce risk of further injury when still symptomatic.
" The survey is the largest of its kind to examine the link between policing, traumatic brain injuries and PTSD, and included participants from across the UK. As the research was survey-based, the data is self-reported. However, researchers took steps to ensure it was not obvious to respondents that they were investigating links between head injuries and PTSD.
