Exploring language as an early behavioral marker of Alzheimer's Disease

Professors from the University of Delaware and Carnegie Mellon University will use a $3.7 million RF1 grant from the National Institute on Aging (NIA) to examine language as an early behavioral marker of Alzheimer’s Disease. If successful, this research could pave the way for earlier interventions.


“Identifying these individuals as early as possible gets them into preventive treatments sooner,” said Alyssa Lanzi, assistant professor of Communications Sciences & Disorders at UD.


The study builds on pilot data gathered by Anna Saylor, a third-year doctoral student in the communication sciences and disorders doctoral program, housed in the UD's College of Health Sciences.


“We know a lot about how language develops in childhood but not much about how it changes in older adults,” Saylor said. “Our data suggest subtle language changes might signal future cognitive decline.”


To explore these changes on a larger scale, Lanzi is collaborating with MacWhinney, who founded TalkBank, open science database of language samples. Within TalkBank is DementiaBank, a shared database of multimedia interactions for studying communication in dementia. However, DementiaBank is outdated and limited in demographics, and the quality and rigor of the data need improvement.


Lanzi is seeking to change that. Her five-year study seeks 300 older adults aged 60-90 nationwide from underrepresented backgrounds or populations vulnerable to health disparities.


“Current DementiaBank data is representative of Caucasians of a higher socioeconomic status,” Lanzi said. “We must intentionally recruit people who are at the greatest risk — for example, adults who are Black, Asian, Hispanic, Latin and those living in rural areas.”


The recruitment strategy, rooted in community engagement at locations in Wilmington, Delaware, is part of the novelty of Lanzi’s grant.


“This is a feasibility study to see if our approach in Wilmington can be replicated in other states,” Lanzi said.


Lanzi has also established an advisory committee of nationwide faculty with relevant expertise on specific priority populations. Their input will tailor plans to population needs while data is collected through a central site at UD.


The Delaware Center for Cognitive Aging Research (DECCAR) also provides critical infrastructure for the study.


“This project is an example of the success of DECCAR, and our impact extends far beyond state lines,” said Lanzi, an executive committee member with DECCAR.


Participants selected for the study will participate in a comprehensive cognitive and language testing battery via telehealth, so they don’t have to travel to UD’s campus, which is novel and unique to this study.


“To study their language, they’ll see pictures and be asked to describe them and share stories from their past,” Lanzi said.


Study participants will receive a gift card for participating and feedback about their memory to share with their healthcare provider.


“Building trust and giving back are key elements of our strategy,” Lanzi said.


Lanzi is already preparing for the next phase of her research, supported by an additional $800,000 grant from the NIA. This phase will test the effects of an online treatment Lanzi developed for individuals identified as at risk.


“If we find that language is an early marker of disease, I want to take this research to the next level and develop treatments that teach strategies to enhance independence and improve the quality of life for those at risk of developing dementia,” she said.

Hantavirus cruise ship outbreak: Epidemiologist discusses causes and challenges

A deadly outbreak of hantavirus on a cruise ship currently stuck off Cape Verde, Africa, has put the virus on the national radar for the first time since 1993. University of Delaware epidemiologist Jennifer Horney can talk about the potential for a larger outbreak and the challenges associated with responding to the emergency. There have been nearly 1,000 cases of hantavirus in the U.S. since surveillance began in 1993. That year, an outbreak of the severe respiratory disease in the four corners area of the U.S. Southwest was linked to domestic exposure to rodents, Horney said. Horney can discuss the following points in reference to the Dutch vessel M/V Hondius, which has seen three people die since departing from Argentina on April 1. • The response to this global public health emergency will be challenging given the cuts to U.S. public health and extensive leadership turnover at the Centers for Disease Control and Prevention. • Climate change and global transit likely contributed to the new cases, as rodent populations thrive during certain weather conditions. • When humans inhale rodent feces, urine or saliva, often when dust is aerosolized through cleaning, they can become infected. While symptoms may develop up to two months after exposure, the disease has a mortality rate of up to 50%.

Gritty like his city: How the Philadelphia Flyers' mascot went from punchline to sensation

How did Gritty, the fluffy, orange, menacing whatchamacallit that backs the Philadelphia Flyers, go from a punchline when he was rolled out in 2018 to one of sports' most well-known and beloved mascots? The University of Delaware's Matt Robinson took a shot, and scored, with some answers. Robinson, a professor of sport management at UD's Lerner College of Business & Economics, said Gritty embodies the tough attitude that Philadelphia is known for. Also, some of his bizarre features and personality traits go straight to the heart of the demeanor and history of the Flyers, who are currently battling their way through the NHL playoffs. Those are among the ingredients that go into marketing and launching a successful mascot.  Robinson can discuss the following: • Why some mascots take off and others flop. After his launch, Gritty was ridiculed as a concept on late night TV and "Saturday Night Live." But he was still garnering billions of views on social media and millions in earned media for the franchise. The Flyers kept pushing the concept despite its early unpopularity, which led to his eventual success. "Any public relations is good public relations," Robinson said. • Mascots need to be authentic. Gritty embodies the team he represents and the city that team plays in. Robinson noted Philadelphia's "grit" and love of players who play hard, like the Broad Street Bullies – the nasty group of Flyers' players who led the team to two Stanley Cup wins in the 1970s.  • The best mascots transcend sports. Robinson pointed to the film and character "Rocky," whose statue sits in the front of the city's Art Museum, as well as the city's reputation as one with a bit of an edge. "We're the ones who threw snowballs at Santa Claus," Robinson said, referring to the infamous 1968 incident when Philadelphia Eagles fans pelted Kris Kringle from the stands. • Players and coaches come and go, but the mascot stays the same. Mascots can be part of ticket sales and community engagement in the offseason, when players may not be in the city or moving to another via free agency. • Mascots offer an attachment point for fans that is not sport related. Kids respond to mascots and, from there, connection with the team, players and the sport can grow. To contact Robinson directly for an interview, visit his profile and click on the "contact" button.

How the Class of 2026 can keep resumes out of the digital black hole

Students set to graduate this May are entering a job market where the rules of engagement are being rewritten in real-time. AI is both friend and foe, and ghosting has become the norm. University of Delaware career expert Jill Panté shares how college students can navigate these challenges in a rapidly shifting economy. Panté, director of the Lerner Career Services Center at UD, can apply her expertise to the following: The AI recruitment gap • How to prevent resumes from falling into the "digital black hole" of automated tracking systems. • Current recruitment in 2026 is heavily filtered by AI. If resumes don't mirror the language of the job description, a human might never even see it. • In 2026, AI is the gatekeeper. Students who aren’t using AI for assistance are working twice as hard for half the results. However, the goal is to use it as a co-pilot, not an autopilot. Beat the bots (tailor your content) • Use tools like Resume Worded or Generative AI like Microsoft Co-Pilot or Gemini to see how resumes stack up against specific job postings. • It is better to send five highly tailored, thoughtful applications than 50 generic ones that get auto-rejected by an algorithm. • Use AI to run a mock interview based on the job description and company. The "hidden” job market • If a "job search" consists solely of clicking "Easy Apply" on LinkedIn for six hours a day, it’s not searching; it’s just doom-scrolling with a resume. Roughly 80% of your time should be spent talking to humans. The other 20% should be spent on applications and research. • Find the recruiter or a department head on LinkedIn. Send a brief (2-3 sentence) note reiterating your interest. • Leverage alumni networks through LinkedIn. Narrative branding • Especially for Gen Z: Hiring managers don't just want to know what you did; they want to know the impact you made. • Instead of saying "Responsible for social media,” say "Increased engagement by 40% over 3 months by implementing a new video strategy." • Always lead with results (LinkedIn, resume, Interviews) to showcase the value you bring. Workforce anxiety • Managing the mental toll of the modern, high-speed job search and the professional "ghosting" epidemic. • Establish a personal "Board of Directors" to provide a balance of support, accountability and feedback. • Maintain momentum by volunteering, attending local networking events and learning new skills on platforms like LinkedIn Learning and Coursera.
