Concussion linked to brain changes in people at genetic risk
Researchers, from Boston University School of Medicine (BUSM) in Massachusetts, and colleagues report their findings - which show promise for detecting the effect of concussion on neurodegeneration - in the journal Brain.

They suggest that their study shows that there is a need to record even mild head injuries because, when combined with genetic risk, they may lead to long-term health problems, such as brain diseases.

In their study background, the researchers note that moderate-to-severe traumatic brain injury is one of the strongest environmental risk factors for late-onset Alzheimer's and other neurodegenerative diseases. However, it is not so clear whether the same applies to mild traumatic brain injury or concussion.
