Traumatic Brain Injury

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.

When someone has been left paralyzed by a stroke or brain injury, much of their recovery involves physically guiding the affected limb though the lost motion, so their brain can relearn it. A new exoskeleton does exactly that for the hand.

In the event of a traumatic brain injury (TBI), chemical changes take place that can act as precursors for secondary damage, and scientists at Ohio State University have demonstrated a new monitoring device that can pick up these warning signs.

In order to train their students, medical schools often get actors to present symptoms of certain conditions. Offering what is claimed to be a more consistent alternative, the HAL S5301 robot is designed to simulate a brain-injured patient.

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 new implantable "brain glue" material could offer a way to intervene in the sequence of events following a traumatic brain injury, by mimicking the supporting structure of brain cells to prevent tissue loss and regenerate neurons.

When someone has experienced a stroke or brain injury, it's not uncommon for them to lose their ability to swallow. A new study, however, suggests that a throat-zapping system could help correct the problem faster than traditional treatments.

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.

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.

Scientists in the UK have developed a new AI algorithm that could help narrow the margin for error in diagnosing brain injuries, with the ability to detect and categorize different types of lesions to gauge the extent of the damage.

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.

Two compelling new studies are building on a hypothesis suggesting age-related dementia is caused by a leaky blood-brain barrier. Experts suggest the studies are interesting but not particularly applicable to human cases of dementia.
