Millions of sports-related concussions occur in the US every year. Many of them happen to high school and college athletes.
Concussion patients were once prescribed rest in a dark room, but in recent years concussion management has literally come out of the dark.

The molecule C1q has both protective and detrimental effects after traumatic brain injury. Blocking it after injury in mice restored normal brain rhythms during sleep and prevented epileptic spikes.
Although a great deal of research is still required, it may one day be possible to identify and treat people either with CTE, or at risk of it.
fNIRS can be done at a patient’s bedside.
By imagining a unique scenario to answer “yes” or “no” questions, this research could potentially be used to communicate with locked-in patients.

Football participation among high schoolers continues to decline, as concern about brain injury increases. Could training without helmets make a difference?
People who have trouble with their speech, say after a stroke, can find it challenging. But a speech pathologist can help.
When people lose their speech, they can stop working and friends can drift away. Here’s what we can do to help them get the rehabilitation they need.
Understanding the facial cues from another person is a component of empathy.
Millions of people suffer traumatic brain injuries, and many lose the ability to emotionally connect with others. A new study suggests there’s a way to help them regain their ability to connect.
