Hearing loss is one of the most common conditions of aging, affecting nearly two-thirds of older adults over the age of 70, but it’s not just a matter of diminished hearing. Hearing loss can contribute to poor psychosocial outcomes for patients including loneliness, depression, and social isolation. New research also shows that hearing loss is linked to a higher risk of cognitive decline and dementia. In fact, the 2024 Lancet Commission on Dementia Prevention, Intervention, and Care identified hearing loss as one of 14 modifiable risk factors for dementia. According to the commission, treating hearing loss could prevent up to 7% of dementia cases globally, making it one of the most impactful areas for potential prevention. This raises the question of whether use of hearing aids in people with hearing loss can reduce or mitigate this increased dementia risk. To help us understand these connections and the latest research in this area, we are joined today by Dr. Alison Huang, an epidemiologist and Senior Research Associate from the Johns Hopkins Cochlear Center for Hearing and Public Health. Her research studies the impact of sensory loss on cognitive and mental health in older adults. Dr. Huang was an author of the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study, a large, multicenter randomized controlled trial that tested whether treating hearing loss in older adults could help slow cognitive decline published in the Lancet.

In this episode Matt and Lauren will speak with Dr. Marcia Pescador Jimenez, an Assistant Professor in the Department of Epidemiology at Boston University whose research focuses on understanding the relationship between exposure to green space and health outcomes (including hypertension and cognitive measures). Emerging research has shown that midlife risk factors may delay or even prevent the onset of dementia later in life - among these include physical activity and social interaction. It’s not a stretch to imagine how a person’s environment may impact behaviors such as physical activity. For instance, there are places that lack sidewalks and parks that make exercising exceedingly difficult. Among environmental epidemiologists, there is growing interest in understanding how the built and natural environment influence our behaviors that, in turn, influence our health. We encourage you to listen to this episode while on a walk outside!

While memory loss is generally thought of as the hallmark of dementia, behavioral and psychological symptoms of dementia like agitation, aggression, anxiety, and hallucinations are nearly universal, affecting almost all patients with advanced dementia. These behavioral disturbances are often the trigger for nursing home placement, and they can be highly distressing for both patients and their care partners. In today’s episode, Matt and Lauren speak with Dr. Ellen McCreedy, a researcher from the Brown School of Public Health who has conducted a study of personalized music intervention called Music & Memory for people living with dementia in nursing homes. Dr. McCreedy is a gerontologist and health services researcher who focuses on evaluation of non-pharmacologic interventions for managing behavioral disturbances of people living with dementia.

In this episode, Matt & Lauren speak with Dr. Lianlian Lei, an Assistant Professor in the Department of Psychiatry at the University of Michigan. Dr. Lei discusses a recent study that looks at the impact of partner’s plan choice on the likelihood of Medicare Advantage disenrollment and how that may impact older adults living with dementia. Unlike traditional Medicare that's administered by the federal government, Medicare Advantage are healthcare plans that are administered by private health insurance companies. These plans can vary a lot and typically cover additional services not covered by traditional Medicare. Navigating the various plan options can be a challenge for older adults, and it's not uncommon for individuals to change plans depending on their current needs.

In this episode, Lauren and Matt talk with Leah Richmond-Rakerd, PhD who is an Assistant Professor in the Department of Psychology at the University of Michigan. Her research focuses on emotional and behavioral dysregulation across the life course. Here, Dr. Richmond-Rakerd will discuss her recent study on “The Associations of Hospital-Treated Infections with Subsequent Dementia: Nationwide 30-year Analysis” that was published in Nature Aging.

Welcome to Season 4 of Minding Memory, where we are welcoming a new co-host, Lauren Gerlach to the Minding Memory team. Lauren is a Geriatric Psychiatrist at the University of Michigan and a member of the CAPRA leadership team. In this episode, Lauren shares a little background on her research interests, what it’s like to be a geriatric psychiatrist, and some lessons learned about using “uncool” emoticons or emojis when texting.
