Children’s concussions and brain rest

For years neurologists have been telling kids with sports-related concussions to give their brains a rest — not only by avoiding physical activity, but also by abstaining from cognitive challenges such as reading, texting, or playing video games for several days. But that advice wasn’t backed by evidence that it helped the brain heal faster, until now.

A new study conducted by researchers at Boston Children's Hospital tracked 335 student athletes who were treated for concussions incurred on the playing field. They found that those who took the most time off from tasks that required a lot of thinking had the quickest recovery from headaches, dizziness, nausea, and other concussion symptoms.
