Traumatic Brain Injury in Veterans May Increase Risk of Dementia

26.06.2014

Older veterans who have experienced a traumatic brain injury (TBI) are 60 percent more likely to later develop dementia than veterans without TBI, according to a study published in the June 25, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.

The study also found that veterans with a history of TBI developed dementia about two years earlier than those without TBI who had developed dementia. 

“These findings suggest that a history of TBI contributes risk for dementia in later life in veterans. If we assume that this relationship is causal, it seems likely that the same increased risk probably occurs with TBI in the civilian population as well,” said study author Deborah E. Barnes, PhD, MPH, of the University of California, San Francisco and the San Francisco Veterans Affairs Medical Center and a member of the American Academy of Neurology. 

The study involved 188,784 veterans with an average age of 68 at the start of the study. All were free of dementia at the start of the study and had at least one visit to a VA health care facility at the start of the study and again an average of seven years later.

A total of 1,229 of the veterans had a TBI diagnosis. During the follow-up period, 196 veterans with TBI, or 16 percent, developed dementia, compared to 18,255, or 10 percent of those without TBI. After adjusting for other factors that could affect the risk of dementia, such as diabetes, high blood pressure, depression and alcohol abuse, researchers determined that veterans with TBI were 60 percent more likely to develop dementia than those without TBI.  

On average, veterans with TBI developed dementia two years earlier than those without TBI, or at age 78.5 compared to 80.7. Also, those who did not develop dementia died 2.3 years earlier if they had a TBI versus no TBI (77.0 years versus 79.3 years). The researchers also found that the risk of dementia was higher in veterans with TBI who also had depression, post-traumatic stress disorder or cerebrovascular disease than in those with either TBI or these other conditions alone. 

“This study convincingly shows that mild trauma has a role in increasing the risk of dementia and sheds light on the more complex relationship between medical and psychiatric diseases with TBI in the development of the future risk of dementias. Neuroscientists must take a careful and comprehensive approach and avoid oversimplified claims of causality,” said Rodolfo Savica, MD, MSc, of the University of Utah School of Medicine in Salt Lake City, and a member of the American Academy of Neurology, who wrote an editorial accompanying the study.

The study was supported by the U.S. Department of Defense/NCIRE and the National Institutes of Health.

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

Im Focus: Into the ice – RV Polarstern opens the arctic season by setting course for Spitsbergen

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.

RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...

Im Focus: Gel filled with nanosponges cleans up MRSA infections

Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.

To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
