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

Read the study from the University of California, San Francisco (UCSF), “Traumatic Brain Injury Strikes 1 in 8 Older Americans,” mentioned by Dr. Chin at 0:30 on the UCSF website.

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.

Guest: Sean Miller, PhD, research scientist, department of ophthalmology and visual science, Yale School of Medicine, co-investigator, Logan Lab, Endicott College

Read Dr. Miller’s study, “SARS-CoV-2 induces Alzheimer’s disease–related amyloid-β pathology in ex vivo human retinal explants and retinal organoids,” on the journal Science’s website.
