On the Pulse: How Resting Heart Rate Improves a Dementia Risk Score’s Accuracy

Posted on

What if your heartbeat could help determine your dementia risk? The CAIDE dementia risk score has long helped clinicians estimate midlife risk for dementia using cardiovascular health factors, but its accuracy hasn’t been equal across populations. New research suggests that integrating resting heart rate meaningfully improves predictive performance across most racial groups. In this interview, Dr. Newman Sze and Shakiru Alaka join us to dig into how and why resting heart rate enhances CAIDE’s accuracy, what the data shows across different racial groups, and what this could mean for earlier, more equitable identification of dementia risk in both research and clinical settings.

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

Posted on

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.

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

Posted on

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.

Traumatic brain injuries (TBI) like concussions are not uncommon, especially in children and older adults. These injuries can have both short-term and lasting effects on the brain, but what about their impact on cognitive function? Dr. Deling He of UW–Madison’s Cognitive-Communication in Aging and Neurogenic Disorders Laboratory (CCANDL) lab joins the podcast to discuss her research on the connections between TBI, speech pathology and cognition and what her study findings mean for people with a history of TBI.

How Occupational Therapists and Speech-Language Pathologists Support Cognitive Health

Posted on

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.
