Research has shown a traumatic brain injury regardless of how severe increases the risk of developing dementia. Research suggests the risk of developing dementia is doubled in those people who have experienced a brain injury.
The study was a retrospective analysis comparing veterans with traumatic brain injury (TBI) to those with no TBI and indicated over a 7-year period, the risk of dementia was more than doubled.
Presented at the Alzheimer’s Association International Conference 2011, it is hoped this new research will provide insight into ways to treat or rehabilitate patients suffering from brain injury.
The study isn’t without its critics. Some studies have suggested there is no correlation between risk and brain injury. Yet researchers showed a clear relation between brain injury and dementia in this study.
While conducted on veterans, study researchers indicated the research had implications on the general population. It highlights the importance for protecting the skull and brain.
