Effects of Increasing Age with TBI[edit | edit source]
Effects on Cognition[edit | edit source]
People who have had moderate or severe TBI are known to have an increased risk of decline of cognitive abilities, and increased risk of dementia, later in life. One 2015 study[1] compared MRI brain scans of people with TBI to a control group; they developed a computer program with an algorithm to estimate the person't "brain age", and the people with TBI were found to have a brain age on average 5 years older than the control group. The authors note: "There was also a correlation between time since injury and predicted age difference, suggesting that these changes in brain structure do not occur during the injury itself, but result from ongoing biological processes, potentially similar to those seen in normal ageing, that progress more quickly after an injury."
This suggests that after TBI there may be secondary process which lead to increasing brain damage for years afterwards[1].
