Traumatic brain injury and cognitive impairment

A recent study published in the Journal of Alzheimer's Disease is opening many eyes. According to research by UT Southwestern Medical Center researchers, traumatic brain injury can increase risk of mild cognitive impairment.

The findings show that individuals who experienced traumatic brain injury and were unconscious for more than five minute are at an increased risk of suffering from mild cognitive impairment.

One author of the study noted the following:

"This is one of the first studies to demonstrate later-life risks of mild cognitive impairment in relation to a remote history of traumatic brain injury in a large population sample."

The author went on to add that it is still difficult to determine who has the highest risk for later-life cognitive decline as a result of traumatic brain injury, but that the results of the study show that a relationship does exist for some.

In the future, the research team hopes to identify the many factors at play.

This was an in-depth study that analyzed cases of more than 3,100 people diagnosed with mild cognitive impairment, compared against roughly 3,200 people with normal cognition.

When people suffer traumatic brain injuries, they may not spend much time thinking about the future. Instead, they focus on the here and now. They are worried about getting their life back on track in the near future. Unfortunately, this may have an impact on these individuals later in life, such as through early onset mild cognitive impairment.

Due to all the risks, anybody who suffers a traumatic brain injury must receive immediate medical attention.
