College athletes who suffer a concussion may take as long as a month to recover, not the two weeks considered normal, new research finds.
"Normal return-to-play time was previously set at 14 days — meaning 50% of people recovered in that time," said lead researcher Steve Broglio. He is director of the University of Michigan Concussion Center in Ann Arbor. "Our paper suggests that 28 day...
The nutrient zinc can be both helpful and harmful when it comes to kidney stones, a new study finds.
There have been two conflicting theories about the link between zinc and kidney stones. One suggests zinc stops the growth of the calcium oxalate crystals that make up the stones. The other suggests zinc changes the crystals' surfaces, which encourages further growth.
There's good news and bad on rates of head injuries among America's bike-riding public: Rates for these injuries have sharply declined among kids but barely budged among the growing number of adult bike riders.
Between 2009 and 2018, increasing helmet use, construction of dedicated bike lanes in cities and other safety interventions have greatly reduced bike-related traumatic brain injur...
It may be possible to treat the thinking problems that result from repeated hits to the head, a new laboratory study suggests.
The new experiments with mice are the first to offer a molecular analysis of what happens in the brain after repetitive but mild blows to the head, said researcher Mark Burns. He is head of the Laboratory for Brain Injury and Dementia at Georgetown University, in ...
People who suffer a traumatic brain injury (TBI) have a significantly higher risk for stroke for years afterward, U.K. researchers say.
Previous studies have linked brain injury with a long-term risk of neurological diseases including dementia, Parkinson's and epilepsy, and it's been suggested that it's also an independent risk factor for stroke.
Here's some good news for aging athletes: If you played high school football, you're no more likely than others to have problems with concentration, memory or depression in middle age, according to a new study.
"Men who played high school football did not report worse brain health compared with those who played other contact sports, noncontact sports, or did not participate in sports dur...
After a concussion, women may be at heightened risk of lasting physical and mental symptoms, a new study finds.
The study of 2,000 concussion sufferers found that women were more likely than men to still have some symptoms one year later. The problems included fuzzy memory and difficulty concentrating, as well as headaches, dizziness or fatigue.
Researchers outfitted high school athletes with head impact sensors to see which of four popular sports put them at the greatest risk of concussion.
No. 1 for both boys and girls: Soccer, according to a study published online recently in the Orthopaedic Journal of Sports Medicine. Blame it on intentional headers, which accounted for 80% of head impacts in that sport.
Modern technology has unraveled an ancient mystery about the death of an Egyptian king.
Computed tomography (CT) scans of the mummified remains of Pharaoh Seqenenre Taa II, the Brave, revealed new details about his head injuries not previously found in examinations since his mummy was discovered in the 1880s. Those examinations, including an X-ray study in the 1960s, had found that the...
Severe winter weather has a grip on much of the United States, which increases the risk of injuries from slipping on ice, shoveling, sports such as skiing and sledding, and car crashes.
"One of the most frequently seen causes for visits to the emergency room this time of year is from slipping on icy sidewalks," said Dr. David Hasleton, senior medical director of emergency medicine and tra...
College football players suffer more concussions and head hits in practice than they do actually playing the game, a new study suggests.
Across five seasons of football, 72% of concussions and 67% of head impacts incurred by players on six National Collegiate Athletic Association (NCAA) Division I teams happened during practice rather than on game day, researchers found.
TUESDAY, Dec. 8, 2020 (HealthDay) -- 'Donorcycles:' That what hospital trauma staff call motorcycles, since riding one without a helmet greatly raises the odds the driver will become an organ donor far too soon.
A new study out of Michigan supports the grim nickname: It found that organ donations among unhelmeted riders rose three-fold after the state repealed its mandatory helmet law.
Targeted microwaves were the likely cause of mysterious illnesses that afflicted staff and their families at U.S. embassies in Cuba and China, according to a U.S. National Academies of Sciences, Engineering, and Medicine report.
Symptoms included ear pain, intense head pressure or vibration, dizziness, visual problems, thinking difficulties and the perception of loud noise.
States with strong football cultures have often fumbled measures to protect young players who've suffered concussions, researchers say.
They analyzed youth concussion laws introduced by states between 2007 and 2014, specifically guidelines requiring a 24-hour delay before sending a player with a possible concussion back onto the field.
The researchers found that states with college ...
After a concussion, it may not be safe to drive for a while, a new, small study suggests.
"People who have concussions often have slower reaction times as a result, and do more poorly on tests of thinking skills after their injury than their peers without concussions," said researcher Julianne Schmidt, from the University of Georgia.
Young children who suffer a concussion are likely to have vision and balance problems, according to a new study.
"Since one-third of pediatric and adolescent concussion injuries occur in elementary school-age children, we set out to provide a comprehensive description of children ages 5 to 11 years who were diagnosed with a concussion to pinpoint opportunities to improve the quality ...
The brain damage that may occur in football players has received a lot of attention in recent years. But a new study suggests that former players who get a diagnosis of chronic traumatic encephalopathy (CTE) when they're still alive may well be getting the wrong diagnosis.
CTE can only be diagnosed with an autopsy, the researchers explained. Other conditions could cause the symptoms ...
Less than half of patients with a sports-related mild traumatic brain injury (mTBI) recover within two weeks, new research shows.
"This study challenges current perceptions that most people with a sports-related mTBI recover within 10 to 14 days," said lead author Dr. Stephen Kara, from Axis Sports Medicine in Auckland, New Zealand.
Padded helmets and safe tackling and blocking techniques can reduce the chance of head injuries for middle school football players, a new study finds.
Young athletes make up 70% of America's amateur and pro football players. As head injuries in older athletes have been linked to a slew of brain injuries, attention is now turning to the safety of the younger players.
Hitting the slopes or the skating rink as the winter of 2020 winds down? Don't let an accident or injury spoil your fun.
"Winter sports and recreational activities have great health and cardiovascular benefits," said Dr. Joseph Bosco, vice president of the American Academy of Orthopaedic Surgeons (AAOS). "However, it's important not to underestimate the risks that cold weather can br...
On college campuses in the United States, students suffer concussions twice as often as believed, and most of those injuries occur off the playing field, new research from the University of Colorado at Boulder suggests.
"This study shows how common head injuries are among this population and that concussions are not restricted to the athletic field," said study co-author Dr. John Brec...
Talking and texting on your smartphone is a big no-no for drivers, but new research suggests the same should be true for pedestrians.
According to one database, more than 2,500 men and women went to an emergency room for head and neck injuries sustained while using a smartphone between 1998 and 2017. When that number is extrapolated to include the whole country, the total is likely to...
When a loved one shows signs of dementia, sometimes a head injury is the cause and MRI scans can help prevent a misdiagnosis of Alzheimer's, researchers report.
As many as 21% of older adults with dementia may be misdiagnosed with Alzheimer's disease, a previous study found. Up to 40% of dementias are caused by conditions other than Alzheimer's disease, according to the Alzhei...
Many brain injury deaths could be prevented by using an inexpensive drug in the critical hours following a head trauma, a new international study finds.
"Traumatic brain injury can happen to anyone at any time, whether it's through an incident like a car crash or simply falling down the stairs," said study co-leader Ian Roberts, a professor of clinical trials at the London School of H...
Only about one in five U.S. adults and one in 10 children and teens who suffered head and neck injuries in cycling crashes said they wore a helmet, a new study finds.
An analysis of data from more than 76,000 cyclists nationwide who experienced such injuries between 2002 and 2012 found that only 21% of men, 28% of women and 12% of younger riders had been wearing a helmet.<...
The length of time that NFL players are sidelined after a concussion has tripled in the past two decades, a new study finds.
Researchers analyzed data from the 2012-2015 pro football seasons. They found that the players who suffered a concussion returned to play an average of 19 days later, which means they missed about 1.5 games.
Repeated exposure to head trauma during play often causes significant brain damage, researchers report. That damage then gives rise to neurological disease, which then boosts the risk for dementia by the time players reach middle-age and beyond.
Even a mild concussion can temporarily affect your sense of smell and trigger longer-term anxiety problems, a new study finds.
It's been known that such problems could occur after a major concussion. But this study found it's also true for minor concussions caused by accidents such as falling off a bike with a helmet on, having a traffic fender-bender, falling on the ski slopes, or sl...
College athletes with attention- deficit hyperactivity disorder (ADHD) may be slower to recover from a concussion and may have more severe symptoms.
That's the preliminary conclusion of a study of 120 U.S. college athletes who suffered concussions. Forty had ADHD; 80 did not. Of those with ADHD, half were taking stimulant medications for the disorder.
