Heather Anderson, a star Australian rules football player who died last November, is the first female professional athlete to be diagnosed with chronic traumatic encephalopathy, or CTE. “She is the first female athlete diagnosed with CTE, but she will not be the last,” researchers wrote in a paper published Friday. Anderson was 28 when she died from what was believed to be suicide. CTE is a progressive degenerative brain disease caused by repeated head impacts, like those suffered when heading a ball in soccer (football). The finding was made possible after Anderson’s family donated her brain to the Australian Sports Brain Bank, hoping to discover “whether a lifetime of exposure to repetitive head trauma contributed to her death,” according to a report co-written by one of the researchers. It was published on a nonprofit academic news site, The Conversation. Dr. Michael Buckland, director of the Australian Sports Brain Bank, identified low-stage CTE when conducting the postmortem analysis. “There were multiple CTE lesions as well as abnormalities nearly everywhere I looked in her cortex. It was indistinguishable from the dozens of male cases I’ve seen,” said Buckland in a news release from the Concussion Legacy Foundation, a nonprofit organization based in the United States. Although women athletes previously had not been diagnosed with CTE, evidence suggests women are more susceptible to concussions in sports than men,…  read on >  read on >

Pickleball has burst onto the scene, inspiring people of all ages to pick up a paddle. But as with any sport, it’s possible to get hurt. Some best practices can help prevent injuries, according to a sports medicine expert. For pickleball players, the most common injury is to the rotator cuff tendon in the shoulder. This can cause shoulder pain, especially with movement and use. Problems range from tendonitis and bursitis to a tear of the tendon itself. Bigger tears can create weakness. Someone might not be able to use their arm. “The unfortunate reality of the rotator cuff is that everyday use can cause tearing and damage,” said Dr. Bruce Moseley, an orthopedic surgeon from Baylor College of Medicine in Houston. “You don’t necessarily have to do anything wrong or abnormal to get a rotator cuff tear — in many instances it just happens as a consequence of living.” Most adults who use their shoulders are at risk. For many people, rotator cuff damage appears over time. In pickleball, reaching overhead requires a lot of force from this tendon, which can worsen rotator cuff injuries. These tears are not preventable. But the shoulder does better when it’s flexible and strong. Moseley suggests stretching and doing light to moderate strengthening. “If you warm up and stretch before your activity and ice down afterwards, your shoulder…  read on >  read on >

Pairing exercise with a 10% weight loss can make a major health improvement in people living with obesity and prediabetes, a new study says. Building in regular exercise more than doubled sensitivity to insulin compared to just weight loss alone. This has the potential to prevent or delay prediabetes from progressing into type 2 diabetes while also decreasing the risk of heart disease, researchers said. “Insulin resistance is a major factor that causes type 2 diabetes, nonalcoholic fatty liver disease and abnormal blood lipids in people with obesity,” said senior investigator Dr. Samuel Klein, director of the Center for Human Nutrition at Washington University School of Medicine in St. Louis. “We’ve shown that combining exercise with weight loss causes a marked improvement in whole-body insulin sensitivity, thereby lowering the risk of developing diabetes and treating obesity-related metabolic diseases to a much greater degree than is possible with weight loss alone,” he said in a university news release. Obesity makes the body resistant to insulin, leading to an increase in blood sugar concentration, Klein explained. The 16 study volunteers were obese, with a body mass index ranging from 30 (the threshold for obesity) to 49. They also had prediabetes, with medical evidence of insulin resistance. Eight of the volunteers were put in a diet-only group and lost 10% of their body weight. The other eight also…  read on >  read on >

Autopsy is currently the only way to definitively diagnose chronic traumatic encephalopathy (CTE), a degenerative brain disease often seen in athletes who’ve suffered repeated blows to the head. But there may be a way to predict which athletes are likely to develop CTE, researchers report June 28 in the journal Neurology. They outline criteria for a condition called traumatic encephalopathy syndrome, where CTE is suspected based on cognitive impairment, behavior changes and other factors. “These findings suggest that this new diagnosis of traumatic encephalopathy syndrome may be useful in professional sports such as boxing and mixed martial arts and may be helpful in predicting who may experience cognitive decline,” study co-author Brooke Conway Kleven said in a journal news release. She is with the University of Nevada, Las Vegas School of Public Health. CTE was originally studied in boxers as “punch-drunk syndrome.” The progressive and fatal brain disease is linked to the development of dementia. For the new study, researchers studied 130 active and retired professional fighters in boxing, martial arts and mixed martial arts. They were a part of a brain health study run by the Cleveland Clinic in Ohio. Participants had brain scans and took cognitive tests when the study began. Researchers found that those who met the criteria for traumatic encephalopathy syndrome had greater declines in brain volume. These participants also had…  read on >  read on >

The number and strength of head impacts, not concussions, cause degenerative brain injuries to football players, a new study suggests. That’s what appears to drive the growing number of cases of chronic traumatic encephalopathy (CTE), researchers say. Chronic traumatic encephalopathy is a progressive and fatal brain disease associated with repeated traumatic brain injuries (TBIs). It is also linked to the development of dementia, according to the Alzheimer’s Association. In this new study of 631 deceased football players, researchers found that the odds of developing CTE were related to the number of head impacts they experienced and how hard those impacts were. “These results provide added evidence that repeated non-concussive head injuries are a major driver of CTE pathology rather than symptomatic concussions, as the medical and lay literature often suggests,” said senior author Dr. Jesse Mez, co-director of clinical research at the Boston University CTE Center. These new data might provide football with ways to prevent CTE, according to researchers. “This study suggests that we could reduce CTE risk through changes to how football players practice and play,” said lead author Dr. Dan Daneshvar, an assistant professor at Harvard Medical School and physician-researcher at Mass General Brigham. “If we cut both the number of head impacts and the force of those hits in practice and games, we could lower the odds that athletes develop CTE.”…  read on >  read on >

A traumatic brain injury (TBI) can have long-term effects, much like a chronic condition, a new study says. Looking at hundreds of patients, researchers found that problems related to traumatic brain injuries can last for years, with people improving and declining at different time points. These problems encompassed memory, thinking and everyday functioning. “TBI is essentially a chronic condition like many other chronic conditions,” said lead researcher Benjamin Brett, an assistant professor in the Departments of Neurosurgery and Neurology at the Medical College of Wisconsin. “Things can change, both up and down, improve and decline throughout multiple years.” Because of this, there’s a need to monitor patients “well beyond that post-injury period,” Brett said. “We need to establish systems of care that involve continued monitoring and treatment.” The idea may be controversial, however. A chronic condition implies an underlying disease that is expected to change and/or get worse in predictable ways, said Dr. Daniel Torres, a neurologist at Northwell Lenox Hill Hospital in New York City. “I would not consider TBI a chronic condition because it is an unpredictable condition with which different individuals can have greatly different consequences,” Torres said. For the study, Brett and his colleagues collected data on more than 900 people who had mild TBIs, mostly concussions, and nearly 200 people who had moderate to severe TBI. These were conditions like…  read on >  read on >
