Neurocognitive testing more accurate than self-reporting of cheerleaders' concussion recovery
Concussions have become a major public health issue, with both short- and long-term side effects. In sports, cheerleading has the highest rate of catastrophic injury, with some studies reporting approximately 6% of total injuries as concussions. Return-to-play guidelines have relied on athletes' self-reports; however, this has led to concerns about the ability of athletes to truly recognize their own symptoms and recovery. In a new study scheduled for publication in The Journal of Pediatrics, researchers evaluate the accuracy of neurocognitive testing compared with self-reported symptoms of concussions in cheerleaders.

An extra hour of TV beyond recommendations diminishes toddlers' kindergarten chances
Every hourly increase in daily television watching at 29 months of age is associated with diminished vocabulary and math skills, classroom engagement (which is largely determined by attention skills), victimization by classmates, and physical prowess at kindergarten, according to Professor Linda Pagani of the University of Montreal and the CHU Sainte-Justine children's hospital.
