A Single Traumatic Brain Injury May Increase Dementia Risks

Jun 15, 2018 | By , on Personal Injury.

If you suffer a brain injury, it is important to consult with a Miami accident attorney for help pursing a claim for compensation. Brain injuries can affect every aspect of your life and can even impact your health over the long-term. For example, according to the New York Times, researchers have discovered that suffering even a single mild traumatic brain injury could increase the risk of developing dementia later in life.

Brain Injuries Can Increase Dementia Risks

The New York Times explained that researchers recently conducted the largest study to-date on the link between traumatic brain injury and dementia.  The study was published in Lancet Psychiatry and it made use of Danish health databases that included everyone who was a resident beginning in January of 1995 who had reached the age of 50 sometime between 1977 and 2017, which was the period of time included in the study. In total, there were more than 2.7 million people who were included in the data used for the research.

The researchers who were using the data identified a total of 132,093 people in the study who had suffered at least one traumatic brain injury. They then adjusted the data for psychiatric illness and neurological illness to determine the dementia risk both for those who had suffered a traumatic brain injury and for those who had not experienced a TBI during the study period.

The data revealed that a person who had a single traumatic brain injury had a 24 percent greater risk of suffering from dementia compared with someone who had never experienced a TBI. In other words, one brain injury could increase the risk of developing dementia substantially. 

Because TBIs can range dramatically in severity, the researchers also specifically assessed the risks associated with experiencing only one mild TBI. Those who had suffered only a mild injury, such as a minor sports-related concussion with no lasting damage to the brain, still had a 17 percent greater risk of dementia than those who had experienced no injuries to the brain at all. Mild TBIs are the most common type, and approximately 85 percent of the patients who were included in the study had experienced only a mild brain injury for their first injury.

Further, the data also found that the more traumatic brain injuries a person had suffered, the greater the increased dementia risk. Those who had experienced five or more injuries, for example, had close to triple the risk of dementia compared with a person who had not experienced any injury to the brain.

While the lead researcher of the study indicated that the absolute risk of developing dementia at a young age – age 50 or under – was still relatively low, the risk was markedly increased as a result of injury to the brain.

When someone causes you to suffer a brain injury, you deserve to be fully and fairly compensated for the damage the injury causes. Contact a Miami accident attorney today to find out what your options are for pursuing a claim for compensation.
