 Context examples: 

In the study, researchers evaluated changes in tau following a sports-related concussion in male and female collegiate athletes to determine if higher levels of tau relate to longer recovery durations.

Players whose heads were hit in a collision two or more times in a two-week period were six times more likely to have concussion symptoms than players who did not have any unintentional head trauma, such as a ball hitting the back of the head or a head colliding with another player's knee, according to a new study.

But, strangest of all, the very instant the shore was touched, an immense dog sprang up on deck from below, as if shot up by the concussion, and running forward, jumped from the bow on the sand.

Technically, a concussion is a short loss of normal brain function in response to a head injury.

(Concussion, Centers for Disease Control and Prevention)

Researchers at the National Institutes of Health found that the blood protein tau could be an important new clinical biomarker to better identify athletes who need more recovery time before safely returning to play after a sports-related concussion.

These results show that heading the ball is indeed related to concussion symptoms, which is contrary to a recent study that suggested that collisions were responsible for most concussions, study author Michael L. Lipton said.

A concussion is a type of brain injury.

Together, these findings indicate that changes in tau measured in as short a time as within six hours of a sports-related concussion may provide objective clinical information to better inform athletes, trainers, and team physicians’ decision-making about predicted recovery times and safe return to play.

Doctors use a neurologic exam and imaging tests to diagnose a concussion.

(Concussion, Centers for Disease Control and Prevention)

Concussed athletes who needed a longer amount of recovery time before returning to play, (more than 10 days post-concussion) had higher tau concentrations overall at six, 24, and 72-hours post-concussion compared to athletes who were able to return to play in 10 days or less.
