Traumatic Brain Injury Connected To Dementia

As the mother of a grown son with a traumatic brain injury, I couldn’t be more excited about the prospect of finding out how to repair even a small part of the damage that changed his life.

In a study released earlier this month, researchers found a connection between traumatic brain injury (TBI) and dementia.

Although this connection has been studied before, the researchers wanted to test the findings in a large-scale study with a long follow up.

Traumatic Brain Injury (TBI) as a Risk Factor

The researchers, using information from 2,794,852 people, over 50 years of age, in Denmark, compared individuals who had suffered a traumatic brain injury with people who had not suffered from TBI and people with non-TBI trauma. Of the three groups, the TBI group were the most prone to suffer from dementia.

On another note, the study also highlighted a greater risk of Alzheimer’s disease.

Main Findings

  • The highest risk period was during the first 6 months after the injury.
  • The risk of dementia increased when with additional TBIs.
  • Age makes a difference. The hazard ratio was greater in people who suffered TBI at a younger age.

Implications

In a somewhat obvious deduction, the researchers concluded that “greater efforts to prevent TBI and identify strategies to ameliorate the risk and impact of subsequent dementia are needed.”

Traumatic brain injury (TBI) is a risk-factor for dementia and Alzheimer’s disease. While these findings may seem scary if you know someone who has suffered a TBI, they also shed light on TBIs devastation and will, hopefully, lead to further research, which will teach us how to better prevent TBI and minimize the chances of dementia.

Do you know anyone who has suffered a TBI? What do they do to take care of themselves?
