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.

Guest: Deling He, PhD, postdoctoral research associate, Cognitive-Communication in Aging and Neurogenic Disorders Laboratory, Department of Communication Sciences and Disorders, UW–Madison

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

What do COVID-19 brain fog and ophthalmology have to do with Alzheimer’s disease? There may be more connections than one might think. Dr. Sean Miller is one of the scientists behind a recent study that used retinal tissue to investigate the links between COVID-19 infections and the build-up of amyloid and other indicators of Alzheimer’s disease in the central nervous system. Dr. Miller joins the podcast to discuss his research and its implications for COVID and dementia diagnosis and treatments in the future.

Caring for someone living with dementia can be both deeply meaningful and incredibly challenging. Finding effective ways to connect, communicate and provide support often requires shifting how we see and respond to changes in the brain. In honor of National Family Caregivers Month, renowned dementia care specialist Teepa Snow joins the podcast to share her insights on improving life with dementia through empathy and understanding. As the founder of Positive Approach to Care (PAC), Teepa has developed the Snow Approach, a set of practical and compassionate techniques designed to empower care partners. She discusses the philosophy behind her methods, the importance of recognizing retained abilities and strategies that can make daily interactions more positive and meaningful for both care partners and those living with dementia.

Guest: Teepa Snow, MS, OTR/L, FAOTA, dementia care specialist, educator, owner, trainer, Positive Approach LLC, co-Founder & chair, Snow Approach Foundation
