Advancing early and equitable detection of dementia: key learnings/challenges, recent innovations, and future directions.

Worldwide, over half of all individuals with dementia are undiagnosed. In the United States, racial, ethnic, and economic inequities mirror global findings, with higher rates of missed and delayed diagnosis and poorer diagnostic quality among minoritized and disadvantaged groups. For example, delayed diagnosis is more prevalent among people identifying as non-Hispanic Black or Latino than non-Hispanic White. Systematic efforts to improve detection can increase diagnosis rates; there is broad consensus that earlier detection and initiation of focused care and support services benefit both affected individuals and their loved ones. Systemic under-detection and its contributions to persistent population-level suffering underscore the importance of early detection of dementia as a key public health issue. Improving early detection calls for comprehensive, coordinated responses from local, regional, and national public health systems in partnership with health care delivery systems and community-based organizations. The Public Health Center of Excellence on Early Detection of Dementia (PHCOE on EDD), funded by the Centers for Disease Control and Prevention (CDC), is a national resource to promote understanding and implementation of evidence-based and evidence-informed public health strategy for early detection of dementia. We, together with the PHCOEs on Dementia Risk Reduction and Dementia Caregiving, and nearly four dozen state and local initiatives, seek to operationalize the priorities of the Building Our Largest Dementia Infrastructure for Alzheimer's Act and National Healthy Brain Initiative, established by federal legislation in 2018 and 2024. Our efforts support the CDC's mandate to build a national public health infrastructure for brain health and dementia.
