Implementing early detection of cognitive impairment in primary care to improve care for older adults

Abstract

Primary care is the ideal setting for early detection of mild cognitive impairment (MCI) and Alzheimer's disease and related dementias (ADRD), as it serves as the primary point of care for most older adults. With the growing aging population, reliance on specialists for detection and diagnosis is unsustainable, highlighting the need for primary care-led assessment. Recent research findings on successful brain health prevention strategies, AD diagnostic tools, and anti-amyloid treatments empower primary care to play a central role in early detection and intervention. Primary care-focused resources are being developed, including tools for cognitive assessments and materials designed to educate patients about brain health and initiate discussions on lifestyle modifications, thereby making early detection more feasible and efficient. Identifying risk factors early enables providers to implement interventions that can slow cognitive decline and improve outcomes for patients and caregivers. If left undetected and unmanaged, MCI and ADRD can lead to worse outcomes, including increased falls, hospitalizations, financial vulnerability, and caregiver stress. Early detection enables the identification of reversible causes of cognitive impairment, supports the management of comorbidities worsened by cognitive decline, mitigates safety risks, and can preserve quality of life. Importantly, primary care is essential for addressing ADRD-related health disparities that disproportionately affect racial minorities, rural populations, and those of lower socioeconomic status. With a focus on the United States healthcare system, this perspective addresses how implementing early detection practices into primary care can improve outcomes for patients and caregivers, reduce societal burdens, and promote health equity in ADRD care.
