A world-first international study led by the University of South Australia has identified a new drug to stop athletes developing dementia after sustaining repeated head injuries in their career.
A neurologic pathway by which non-damaging but high frequency brain impact blunts normal brain function and causes long-term problems with learning and memory has been identified. The finding suggests that tailored drug therapy can be designed and developed to reactivate and normalize cognitive function, say neuroscientists at Georgetown University Medical Center.
Every year, nearly 2.5 million U.S. high school athletes participate in contact sports. Each of these athletes sustains an average of 650 subconcussive head impacts in a single season, hits that can negatively affect brain health.
Psychology chair Heidi Wayment co-authored the report with Ann Huffman, Deborah Craig and Monica Lininger. The work was a result of a grant funded by the Mind Matters Challenge, which provides recommendations for increasing concussion symptom disclosure in collegiate athletic departments and military service academies.
Even mild concussions cause severe and long-lasting impairments in the brain’s ability to clean itself, and this may seed it for Alzheimer’s, dementia and other neurodegenerative problems.
ASU sociologist finds team-oriented exercises benefit us socially and can also increase life span
Middle school football players greatly reduce the chance of head injuries if they wear padded helmets and use safe tackling and blocking techniques, according to Rutgers researchers.
Humans have been cooling metal mixtures from liquid to solid for thousands of years. But surprisingly, not much is known about exactly what happens during the process of solidification. Particularly puzzling is the solidification of eutectics, which are mixtures of two or more solid phases.
A team of researchers, led by Philip V. Bayly in the McKelvey School of Engineering at Washington University, plans to use MRI to study the brains of healthy, uninjured individuals to create models of brain motion to enable the researchers to predict the chronic effects of repeated head impacts in both men and women.
