Lowered inhibition found in one study of concussion sufferers were mirrored in separate tests on Canadian university football players. The findings open new doors to predicting the impact of the often debilitating injury, as well as raise questions about the long-term impact of contact sports, according to researchers. Led by graduate student Clara Stafford, the… Read more

Many cases of autism spectrum disorders (ASDs) may result from problems in immune cells that normally work to trim back unneeded brain connections in early life, suggests a new study led by scientists at Scripps Research. The study[1] examined the effects of a set of gene mutations that account for a small percentage of autism… Read more

People with a gene variant that puts them at high risk for Alzheimer’s disease are protected from its debilitating effects if they also carry a variant of a completely different gene, Stanford University School of Medicine investigators report in a large new study. Their findings[1] suggest that a substantial fraction of the estimated 15% of… Read more

A new study offers clues to why autism spectrum disorder (ASD) is more common in boys than in girls. National Institutes of Health scientists found that a single amino acid change in the NLGN4 gene, which has been linked to autism symptoms, may drive this difference in some cases. Researchers led by Katherine Roche, Ph.D… Read more

High blood levels of RNA produced by the PHGDH gene could serve as a biomarker for early detection of Alzheimer’s disease, researchers at the University of California San Diego have discovered. The work[1] could lead to the development of a blood test to identify individuals who will develop the disease years before they show symptoms… Read more
