More Insights into How Prions Invade The Brain

The spread of prions to the brain does not occur by direct transmission across the blood-brain barrier, according to a new study. As noted by the authors, insights into how prions enter the brain could lead to the development of effective strategies to prevent neurodegeneration, even after infection outside the nervous system has already taken place.

Cancer Treatments May Affect Cognitive Function by Accelerating Biological Aging

Cancer treatments are suspected to accelerate certain aging processes in the body. A new study has found that indicators of such biological aging correlate with declines in cognitive function in women who had undergone breast cancer treatment several years earlier. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the findings point to an aging-like effect of cancer treatments and further connect this to cognitive decline

Home Videos Of Children Can Be Scored to Diagnose Autism, Study Reports

The research, which will be published online Nov. 27 in PLOS Medicine, expands on a 2014 feasibility study on the topic by the same researchers. In the new study, the scientists employed machine learning to determine which features of children's behavior should be rated to evaluate autism, using computers to whittle down a long list of behavioral features to those most relevant to the diagnosis. They also devised an algorithm that weights each feature to provide an overall diagnostic score for each child
