Alzheimer’s and Traumatic Brain Injury

If you have ever had a friend or loved one die from Alzheimer’s, you know how tragic that disease can be. Even more heartbreaking is early onset Alzheimer’s. It robs a person not only of their old age but of time with their family and friends during their prime.

Research shows that Traumatic Brain Injury is linked to the development of Alzheimer’s or another type of dementia. This may occur years after the original head injury.

Moderate and Severe TBI

Moderate and severe TBI is the culprit creating an increased risk of Alzheimer’s.

Key studies show that the increased risk of Alzheimer’s in older adults with a history of traumatic brain injury is 2.3 times that of senior citizens with no history of a head injury. Those with a severe traumatic to brain injury were found to have a 4.5 times greater risk of developing dementia.

Individuals who have suffered repeated many blows to the head without a loss of consciousness are also at a higher risk of developing a brain condition. Studies show a link between moderate and severe brain injury and that elevated risk.

Repeated Blows and CTE

Chronic Traumatic Encephalopathy (CTE) is a progressive degenerative disease of the brain found in people with a history of repetitive brain trauma (often athletes).

Repeated blows to the head and TBI are related to CTE

Earlier Onset Alzheimer’s From TBI

The onset of Alzheimer’s was 10 years earlier in the group that suffered TBI than a control group. Expected onset of Alzheimer’s was 18 years in the non-head injury group. Individuals loss a possible eight years of living without Alzheimer’s.

This is a significant quality-of-life issue.

Cases of Alzheimer’s among people with TBI younger than age 65 was more than twice the expected number.

Not All Develop Dementia

A head injury does not mean that an individual will develop dementia. A single mild brain injury shows no increase in the possibility of developing Alzheimer’s, but more research is needed..

Protein Abnormalities

The chemistry of the brain changes because of traumatic brain injuries. Research indicates a relationship between TBI and a hallmark protein anomaly. These changes are linked to Alzheimer’s. Again, more research is needed.

Traumatic brain injury dementia is also related to a variation of the gene for a protein called A POE-E for. More research is needed to understand the link between TBI, this protein, and dementia.

Issues surrounding Traumatic Brain Injury and Alzheimer’s are complex. We would like to help your understanding if we can.
