A comprehensive vision assessment should be part of return-to-learn protocols to help determine when children are ready to return to the classroom following concussions - particularly in children reporting academic difficulty, says a new study.

As summer swelters on, those on the front line of athletic care should be especially vigilant of hyponatremia when treating sick patients or advising healthy individuals. Recommend having a variety of fluids freely available and advise people - especially exercising athletes - to drink when thirsty and reduce activity, splash with water, and seek a shaded spot when hot. Before we promote blanket advice to "drink lots of fluid" and "stay well-hydrated", we should be mindful that fluid is a balance - especially during exercise.

Despite widespread media coverage and speculation regarding the late-life or post-retirement risks of cognitive impairment in athletes who engaged in sports involving repetitive blows to the head and high concussion risk, and assertions that CTE causes them to be at high risk of suicide, there have been virtually no peer-reviewed, well-designed scientific studies that establish, much less quantify, such risks.

A study by researchers at Boston University finding that athletes who were less than 12 years old at the time of their first exposure to tackle football had more behavioral and cognitive problems later in life than those whose age of first exposure to the sport was later has, predictably, garnered a great deal of attention from the mainstream media. In the interest of balanced and objective reporting, we asked a number of researchers and clinicians to review and comment on the study. Here's what they told us.

Are men who played high school football in Minnesota in the twenty-five years after World War II at increased risk of later developing dementia, Parkinson's or ALS compared with non-football playing high school males? Not according to two studies by researchers at the Mayo Clinic.
