A recent study from researchers at the University of Wisconsin School of Medicine and Public Health found that people who lived in the most disadvantaged neighborhoods were about twice as likely to have Alzheimer’s disease-related brain changes at autopsy than people who lived in the wealthiest neighborhoods. One of the authors joins the podcast to discuss the research findings, the methodology behind the study, and future research directions. Guest: Ryan Powell, PhD, University of Wisconsin School of Medicine and Public Health Department of Medicine

What do you do if you have a family history of dementia and are experiencing symptoms, but can’t get a diagnosis? Dr. Sara Langer has dealt with just that. In the latest episode of our Voices of Research Participants series, Dr. Langer shares the obstacles she endured to receive her diagnosis of Lewy body dementia (LBD), how her background as a neurologist influenced her search for clinical care and how she turned to dementia research to find answers. She also discusses ways that the field of dementia research could improve to support those with other forms of dementia outside of Alzheimer’s disease.
Guest: Sara Langer, MD, neurologist
Co-host: Sarah Walter, MSc, program administrator, Alzheimer’s Clinical Trials Consortium (ACTC) and Alzheimer’s Therapeutic Research Institute (ATRI)

Living with Lewy Body: A Neurologist’s Journey Through Research and Dementia Care

The brain is the most complex part of the human body, controlling thought, memory, emotion, motor skills, sensory input and all the processes that regulate our bodies. How exactly does it work, and how are clinicians able to determine whether brain changes are a result of normal aging, Alzheimer’s disease, or something else? Dr. Victoria Williams joins the podcast to explain important concepts in neuropsychology, from the difference between cognition and intelligence to how memories are made, and discuss how cognitive tests work in memory clinics.

The Fundamentals of Neuropsychology: Breaking Down Cognition, Memory and More

Since the COVID-19 pandemic was declared by the World Health Organization (WHO) in 2020, there have been many concerns about how cases of COVID-19 and Long COVID or Post-COVID Conditions (PCC) affect not just a person’s physical health, but their cognition as well. In this episode, Dr. Jim Jackson talks about his path into critical illness research and his dedicated focus on unraveling the impact of Long COVID on cognition. Throughout the discussion, he talks about the parallels between Long COVID and other chronic illnesses, the effects of Long COVID across different demographics, the concurrent challenges faced by older adults and more.

Long COVID and Its Effect on Cognition

Hearing loss affects roughly 15.5% of Americans 20 years and older. While the majority of these individuals experience mild hearing loss, the prevalence and severity of hearing loss increases with age. What does this sensory change mean for dementia risk, and can this risk be prevented through interventions like hearing aids? Dr. Frank Lin joins the podcast to discuss the relationship between hearing loss and dementia and share findings from the Aging and Cognitive Health Evaluation in Elders, or ACHIEVE, study.

Listen Up! The Connections Between Hearing Loss, Hearing Interventions and Cognitive Decline

Caring for a loved one with cognitive decline can be challenging. While it is a labor of love, burnout is all but inevitable. In this episode kicking off our Voices of Research Participants series with co-host Sarah Walter, Cynthia Sierra touches on her personal experience with caregiver burnout as both a caregiver and research study partner for her mother, who has early-onset Alzheimer’s disease. She also shares her unique perspective on Alzheimer’s disease research as someone who started as a family caregiver.
