LIMBIC-CENC has been busy over the last 6 years studying the effects of mild TBI on military Service Members and Veterans. One major challenge is that there is no actual specific test to say for certain if someone has a concussion. Instead the diagnosis is made from talking to the person about the event and the symptoms they have. Obviously, one single way of doing this would be helpful. So, LIMBIC-CENC developed a standard interview form so that all LIMBIC-CENC participants are interviewed the same way each time no matter where or when the study site is located. This LIMBIC-CENC standard interview is available to brain researchers all around the world.

LIMBIC-CENC has learned that mild TBIs are linked with many other conditions. For example, TBIs and PTSD symptoms are often found together. LIMBIC-CENC has been learning how the two are linked (think “chicken and egg”) so that both conditions can be treated better. We are also studying many other conditions that occur to people with TBI to see if they are related.

LIMBIC-CENC scientists have also been looking at markers in the blood and at brain images that may show connections between late-life dementia and TBI. Studies will take more time, but several interesting trends have been seen. Also, we are busy thinking about single versus repeated mild TBIs and how they affect the brain.

None of these exciting projects would be possible without the time and dedication of our participants. We thank you!
