Brain Clearance System Alteration and Cognitive Decline in African Americans with Poor Sleep Quality

3:00 PM to 4:30 PM

Held via Zoom
Registration is required

This lecture is held as part of the Winkelman Memorial Virtual Lecture and features Karen D. Lincoln, PhD, MSW, MA, FGSA. 

Karen Lincoln, PhD, MSW, MA, FGSA

Dr. Karen D. Lincoln, a Professor in the Department of Environmental and Occupational Health and Director of the Center for Environmental Health Disparities Research at UC Irvine, is a distinguished social worker and sociologist. Specializing in the social determinants of health and well-being among Black Americans, her research delves into psychosocial factors such as social and chronic stress, discrimination, and social connections. Dr. Lincoln's work extends across the life course, investigating mental and physical health outcomes for Black/African Americans and other minoritized groups. Her primary objective is to enhance clinical and community-based care by exploring the psychosocial, behavioral, and biological mechanisms connecting environmental and social determinants to well-being among minoritized adults.

The Leon and Josephine Winkelman Lecture Series was established at the University of Michigan School of Social work by the Winkelman brothers - Stanley J., John, Frederick R., and Henry R. - as a memorial to their parents. 

The lecture series provides a forum for the presentation of new and emerging knowledge from the social sciences and the helping professions in the field of gerontology and for the discussion of the applications of such knowledge to the development of social policy, the organization and management of social welfare services, and the delivery of social work services.

Course Description

This presentation provides an in-depth exploration of the relationship between sleep quality, brain clearance systems, and cognitive decline, with a specific focus on the African American population. Participants will delve into the mechanisms behind the brain clearance system, its alteration in the context of poor sleep quality, and the subsequent impact on cognitive functions.

Learning Objectives
  1. Describe the brain clearance system.
  2. Describe the impact of sleep on cognitive decline among African Americans.
