Trauma

A blood test could help reduce the risk of long-term damage for participants of contact sp...

It wasn't so long ago that shaking off a knock to the head and getting back on the field was seen as a sign of toughness for sportspeople. But in recent years, increased awareness of the potential for long-term damage has put the seriousness of concussion in the spotlight. Researchers at Sahlgrenska Academy in Sweden have now developed a blood test that reveals the severity of a concussion and when it is safe for a player to return to the game.  Read More

Nevermind detects the player's fear levels making the game harder as their fear rises and ...

While traditional horror video games seek to provide an exciting thrill, Nevermind is a biofeedback-enhanced horror game that has greater ambitions. It requires you to manage your anxiety in alarming scenarios – the more stressed you feel, the harder the game becomes. The aim, says Erin Reynolds, its creator, is for players to learn how to not let their fears get the best of them in nerve-wracking situations and hopefully carry over their gameplay-acquired skills into the real world.  Read More

The VEPS sensor can detect signs of traumatic brain injury (TBI) that can result from blow...

Victims of penetrating head injuries usually seek immediate attention, as the hole in their skull is difficult to miss. However, people with closed-head injuries may show few immediate signs of the trauma, and appropriate diagnostic equipment (primarily a CAT scanner) is often not immediately available. A Mexican-US team of researchers has now developed a simple, easy to operate, and inexpensive electromagnetic sensor for traumatic brain injuries, suited to on site use by field personnel and paramedics.  Read More

Animation still of the DARPA foam being injected

The Defense Advanced Research Projects Agency (DARPA) is developing a foam that can be injected into the body cavities of battlefield wounded to protect them from internal abdominal bleeding. The agency hopes that when perfected, this polyurethane polymer foam will help the wounded to survive the critical minutes needed to transport them to proper surgical facilities for treatment.  Read More

The US Army and the US National Football League are cooperating on a project to develop be...

The US Army is now working with the US National Football League (NFL) to develop ways to protect their respective members at risk of repeated incidents of mild traumatic brain injury (MTBI), traditionally called concussions. The first step of the program is to install sensors in the protective helmets so that the conditions leading to MTBI can be understood. Once understood, new helmet designs will provide more protection against such injuries.  Read More

A new technique known as mechanical tissue resuscitation has been shown to reduce the cell...

When the brain receives a traumatic injury, irreversible damage occurs as the cells at the point of impact die. Injured cells surrounding the area then release toxic substances, which cause the brain to swell. This decreases blood flow within the brain, leading to lower oxygen levels, which in turn leads to more cell deaths. Recently, however, scientists from North Carolina’s Wake Forest Baptist Medical Center have developed a new technique, that has greatly reduced the secondary cell deaths in brain-injured lab rats.  Read More

U.S. researchers have developed a nonsurgical technique to repair severed nerves in minute...

Professor George Bittner and his colleagues at the University of Texas at Austin Center for Neuroscience have developed a simple and inexpensive procedure to quickly repair severed peripheral nerves. The team took advantage of a mechanism similar to that which permits many invertebrates to regenerate and repair nerve damage. The new procedure, based on timely application of common chemicals to the severed nerve ends, could help patients to recover nearly full function in days or weeks.  Read More

Biomedical engineering students have invented a blood-warming device, intended to reduce t...

For U.S. troops, the most common type of battlefield fatality involves blood loss due to trauma. When a soldier does experience blood loss, their chance of survival drops by 22.5 percent once hypothermia sets in. Needless to say, if that reaction can be minimized or delayed, then less fatalities should occur. A team of biomedical engineering students from New Jersey’s Stevens Institute of Technology is working towards that goal, by developing a blood-warming system device known as Heat Wave.  Read More

Researchers have developed a one-minute sideline test for athletes, that accurately detect...

By developing a simple one-minute sideline test, researchers at the University of Pennsylvania School of Medicine have tackled the issue of diagnosing concussion head on. Up until now sideline tests for concussion have been vague and often miss a large spectrum of brain functions that may have been affected. It is a well-known fact that any concussion left untreated or ignored may lead to serious or potentially fatal consequences, thus the Pennsylvanian researchers are eager to get this simple and effective test into action.  Read More

Researchers have determined that playing Tetris minimizes the mind's tendency to flash bac...

If you’ve seen something you’d prefer to forget, then playing Tetris might be just what you need – provided you do it within six hours. That’s the conclusion reached by a team of psychiatric researchers from Oxford University, led by Dr. Emily Holmes. In a study involving 60 test subjects, it was found that people who played the video game within six hours of viewing traumatic images had less of a tendency to experience flashbacks of those images afterward. It all has to do with the way in which the brain processes experiences.  Read More
