Could Managing Four Common Health Conditions Slow Cognitive Decline from Alzheimer’s?

Alzheimer’s disease isn’t always the only health condition a person faces, so how does treating other diseases impact the progression of Alzheimer’s? Researchers at the University of Arizona focused on four common health conditions – type two diabetes, hypertension, inflammation and dyslipidemia – which are known to increase the risk of developing Alzheimer’s disease, and set out to investigate whether those diagnosed with Alzheimer’s who received treatments for these four conditions also saw a delay in cognitive decline. Dr. Barb Bendlin joins the podcast to break down the findings from this research, as well as discuss the impact of personalized prevention strategies and combination therapies. Guest: Barbara Bendlin, PhD, professor, Division of Geriatrics and Gerontology, University of Wisconsin (UW) School of Medicine and Public Health, deputy director, UW Center for Health Disparities Research (CHDR) Show Notes Read the study, “Combination therapy targeting Alzheimer's disease risk factors is associated with a significant delay in Alzheimer's disease–related cognitive decline [https://alz-journals.onlinelibrary.wiley.com/doi/10.1002/trc2.70074],” published by Alzheimer's & Dementia: Translational Research & Clinical Interventions on the Alzheimer’s Association’s website.  Read more about the study in the article “Four Key Pieces Managing Common Health Conditions Slows Alzheimer's Progression [https://www.naccdata.org/nacc-navigator/four-key-pieces-managing-common-health-conditions-slows-alzheimers-progression/],” published on the National Alzheimer’s Coordinating Center’s website.

Taking Steps to Slow Decline: New Study Examines the Role of Physical Activity on Alzheimer’s Progression

10,000 – that’s the magic number of steps often recommended for a healthy lifestyle. With recent research looking into whether that number is an accurate benchmark for health, could the number of steps taken per day have an impact on brain health and, specifically, cognitive decline? That’s precisely what a new study from Harvard Medical School and Mass General Brigham sought to examine, looking at how physical activity, specifically step count, impacted cognitive decline for those living with Alzheimer’s disease. Dr. Bri Breidenbach and Sarah Lose join the podcast to break down the results of this new study, as well as share what current research says about the effect of other kinds of physical activity, such as different intensity exercises, on the brain and Alzheimer’s progression. Guests: Bri Breidenbach, PhD, scientist, exercise physiologist, Okonkwo Lab, and Sarah Lose, MS, research program manager, exercise physiologist, Okonkwo Lab, UW School of Medicine and Public Health   Show Notes Read the study, “Physical activity as a modifiable risk factor in preclinical Alzheimer’s disease [https://www.nature.com/articles/s41591-025-03955-6],” published by the journal Nature Medicine on their website.

How Occupational Therapists and Speech-Language Pathologists Support Cognitive Health

When memory, thinking or communication changes begin, knowing where to turn for support can make all the difference. In this episode, we explore how two key health care specialties can help individuals and families meet those challenges with confidence. Sarah Gunderson, an occupational therapist, and Kari Esser, a speech-language pathologist, draw from their work supporting people experiencing a wide range of neurological conditions to walk us through the foundations of their specialties and their unique roles in mild cognitive impairment (MCI) and dementia care. Sarah and Kari also provide a preview of their upcoming talk, “Partnering with Your Healthcare Team,” as part of the 2025 Healthy Living with MCI education program. Guests: Sarah Gunderson, OT, occupational therapist, UW Health, Kari Esser, MS, CCC-SLP, speech-language pathologist, UW Health Show Notes Register and learn more about the upcoming Healthy Living with MCI event featuring Dr. Chin, Sarah Gunderson and Kari Esser, happening on December 12, 2025, and future programs on our website [https://www.adrc.wisc.edu/mci].
