Evidence links Traumatic Brain Injury (TBI) with elevated dementia risk


The link between Traumatic Brain Injury (TBI) and dementia has been known for some time, but evidence continues to mount to support the notion that the former can act as a precursor to the latter. Within this article, brain injury lawyers Blackwater Law discuss the latest research findings.

Key research findings on TBIs and dementia

  • A 2020 study by Kornblith E, Peltz CB, Xia F et al featured in the Neurology journal shows patients with a history of TBI are 2-3 times more likely to go on to develop dementia, with even comparatively minor forms of brain injury contributing to elevated risk.
  • Longer terms studies such as Schneider ALC, Selvin E, Latour et all’s examination of some 14,376 participants who suffered TBIs, have also confirmed a strong association between sustaining brain injuries and increased risk of developing dementia over a 25-year period thereafter.
  • Research from University of Pennsylvania Perelman School of Medicine also points to a dose-response relationship between TBIs and dementia risk, suggesting those who have repeatedly suffered head injuries are at greater risk than those involved in one-off events.

How do TBIs cause dementia?

As the body of evidence growths in support of the notion that TBIs contribute to greater risk of developing dementia, the exact mechanisms of action are still the subject of some debate in the scientific community.

Some researchers posit the notion that TBI’s reduce neural and cognitive resilience in the victim, reducing their capacity to weather the natural effects of aging and making them more susceptible to degenerative brain conditions. It has also been suggested that TBIs contribute to the accumulation of abnormal proteins in the brain, resulting in impaired function and the onset of a condition known as chronic traumatic encephalopathy (CTE).

Others argue that TBIs could result in structural damage to the brain which impairs function, or that they can result in neurochemical changes or imbalances that similarly contribute to neurodegenerative processes.

Making a Traumatic Brain Injury Claim

If you’ve suffered one or multiple TBIs during your work or in sporting events, your risk of developing dementia is significantly heightened. Whilst you cannot go back and undo the damage to your brain, you could be able to secure financial compensation to help you fund treatment should you require it.

If your employer or those responsible for your wellbeing failed to take the necessary precautions to protect your safety and wellbeing during the period where you sustained your TBI, they could be liable for any adverse health affects you are experiencing as a result. It may be appropriate to seek a brain injury claim as a result.
