In May 2023, the U.S. Surgeon General, Dr. Vivek Murthy, released an advisory calling attention to the public health crisis of loneliness and social isolation in the U.S. With this widespread issue affecting such a broad population, how does social isolation impact older adults? Dr. Alison Huang joins the podcast to share insights from her study on the relationship between social isolation and the risk of dementia in older adults. Using data from a nine-year National Health and Aging Trends Study (NHATS), she discusses how factors like living alone, limited social networks and reduced activity participation contribute to increased dementia risk.

The APOE gene is recognized as a significant genetic risk factor for cognitive decline, with different alleles, like APOE e2, being seen as protective against decline and others, like APOE e4, indicating an increased risk for cognitive decline. However, new studies are looking at whether these trends are universal across different racial and ethnic groups. Dr. Cally Xiao joins the podcast to discuss her study, which focuses on how different APOE alleles affect risk for Alzheimer’s disease within Hispanic populations compared to non-Hispanic populations.
