Last week, NFL great Brett Favre revealed publicly that he has Parkinson's disease. It was an announcement that has also put the devastating affliction back in the media spotlight, and has experts and the public wondering if there's a link between high-impact sports like football and Parkinson's.



It's why researchers like Christopher Watts from TCU are getting contacted by national media looking for answers.



Head trauma alone is not the sole risk factor for Parkinson’s. Experts say the disease has also been linked to environmental factors, like exposure to certain pesticides or chemicals, and genetic mutations.

“If all the ingredients in the recipe come together, you may develop Parkinson’s disease,” said Christopher Watts, Texas Christian University's Dean of the Harris College of Nursing & Health Sciences, who researches the disease. “The reason why we know is because not every boxer develops Parkinson's disease… it has to be other things that are acting along with that exposure to head trauma.”

The median age for a Parkinson’s diagnosis is about 65, Watts said. At 54, Favre is on the younger end of that spectrum.

Parkinsonism – an umbrella term for brain conditions that cause slow movement, rigidity and tremors – has been well studied in boxers, Watts said. One of history’s most legendary boxers, Muhammad Ali, was diagnosed with the disease.

However, the research among football players isn't as robust. A 2023 study published in JAMA found participants with a history of playing organized football had higher odds of Parkinsonism or Parkinson's disease compared with those involved in other organized sports. But other studies have reported mixed findings, Watts said.

He said researchers must determine if there is a link.

“Football is such a big part of American society,” he said. “We need to know the answers to this.”

The Research Behind the Reputation: TCU’s Dr. Ledbetter Maps the Science of Taylor Swift’s Storytelling

At Texas Christian University, Dr. Andrew Ledbetter, Chair of the Communication Studies Department, is turning his scholarly attention to one of pop culture’s biggest phenomena: Taylor Swift. His research uses data-driven analysis to reveal how Swift’s albums and songs build an interconnected narrative universe — what he calls her “Taylorverse.” Ledbetter ran lyrics across ten albums through semantic-network software to show how certain songs act as linchpins connecting themes of fame, womanhood, love and storytelling. “I was interested in interconnections among the song lyrics,” says Ledbetter. “The songs that are most central have a lot of overlap with other songs, might tend to be songs that are the most popular.”  November 03 0 NBC News The work stands out not just for its pop-culture relevance, but for its academic innovation: combining computational text-analysis with narrative theory to unlock why certain tracks resonate more deeply than others. For journalists, cultural commentators or anyone covering the evolving intersection of music, identity and media, Dr. Ledbetter is a go-to expert. He can speak to how storytelling in music shapes audience engagement, how media fandom becomes scholarship, and why Swift’s songwriting continues to spark new research just as much as chart-topping hits.

Experts in the Media: Eating Habits of People Who Grew Up Poor

Sarah Hill, Ph.D, professor of psychology, contributed insights to an AOL article, “Eating Habits of People Who Grew Up Poor,” exploring how early life poverty continues to foster food preferences and mental associations around eating. The piece examines why many adults raised in low-income households feel “unnatural” when switching from inexpensive comfort foods to fresh produce and how habits formed in scarcity can linger long after financial hardships subside. Hill emphasizes that these patterns aren’t just personal quirks but deeply ingrained coping strategies. “For someone who rarely saw fresh fruits or vegetables growing up, the cost, smell, even the way they cut or cook produce, can feel foreign,” she wrote. The article also discusses how scarcity conditioning can lead to behaviors like eating beyond fullness to avoid waste, attachment to “cheap staples” or resistance to change in diet, even when healthy choices are available. Hill argues that recognizing these habits with compassion, as adaptations rather than flaws, is key to promoting lasting healthy change. Sarah Hill is currently a researcher and professor at TCU, lead research advisor at 28, and a thought leader in the area of women’s hormones and sexual psychology. Sarah’s groundbreaking research has resulted in more than 80 research publications. Her work has been featured in The New York Times, The Washington Post, Scientific American, The Economist, and on television shows like Good Morning and The Today Show. See her profile here.

Expert Research: The Surprising Source of Next-Gen Antibiotics: Oyster Blood

Antimicrobial resistance (AMR) is a growing concern across the world and it has doctors worried and scientists working hard to find a solution Basically, AMR is when bacteria and viruses no longer respond to antimicrobial medicines. The result is making infections harder to treat and increases the risk of spreading disease. Recently, Texas Christian University researcher Shauna McGillivray commented on exciting new research in this area that was featured in the media: The search for a solution to antimicrobial resistance found something. And researchers found it in a true “it’s always the last place you look” location. Australian oysters. Or more specifically, Australian oyster blood. Antimicrobial proteins and peptides (AMPPs) “… are an exciting area with a lot of potential,” said Shauna McGillivray, professor of biology at TCU with an emphasis on host-pathogen interactions. “[They] are by themselves very potent but, as has been noted in multiple studies, they can also synergize with existing antibiotics, thereby improving efficacy of antibiotics, even in some cases to antibiotics to which there are high levels of resistance.” Feb. 22 -Phamed.com This is an amazing find and could be groundbreaking for the pharmaceutical industry and health care.
