Concussions

After an athlete has suffered a concussion, it's important that they wait until the injury has healed before returning to the playing field. A new headset is designed to let them know when it's safe to do so, by monitoring their "headpulse."

One of the dangerous things about sports-related concussions is the fact that athletes may not realize they have one, so they don't seek medical attention. A new sensor could let them know, and it would go on their neck, not their head.

Repeated knocks to the head are known to carry increased risks to our neurological health, but a new study has sought to fill in important details around what they might mean for the skull, finding they lead to robust increases in bone thickness.

Scientists may have unearthed a valuable new tool to study brain injuries, in the form of headbutting animals such as bighorn sheep and muskoxen, in which they've discovered hallmarks of head trauma for the very first time.

Scientists at the Houston Methodist Research Institute studying brain impacts have turned to the communities of bacteria in the gut, where they've found that changes following a concussion could be used to reveal the state of recovery.

Researchers have shown in mice how a heightened sense of alert among immune cells may drive some of the long-term consequences to cognitive function after concussion, and opened up new possibilities around therapies for human sufferers.

Although it's important to know if someone has experienced a concussion, the injuries are notoriously difficult to diagnose. According to a new study, however, urine tests may do the trick – plus they could be used to monitor the healing process.

A first-of-its-kind study has explored the connections between repeated concussions and an insidious degenerative brain condition called chronic traumatic encephalopathy, and shown how a new drug may be able to prevent it from taking hold.

Detecting concussion can be tricky business but scientists are working on techniques that can provide more definitive answers, including a test that is said to reveal tell-tale signs of brain injury through the saliva.

Engineers at Michigan State University have crafted a new type of liquid foam lining they say can help football helmets better sustain repeated impacts, improving their longevity and the safety of those wearing them.

A blood test that reveals the severity of brain injuries in hours through a key biomarker was recently approved for clinical use, but researchers are now setting their sights on a point-of-care solution that can deliver results within 15 minutes.

Engineers at the University of Wisconsin-Madison (UW) have been investigating ways of nursing concussed brain cells back to healthy function, and have found that cooling them can protect them from damage and allow them to operate as normal.
