Primary care clinicians play a central role in the early identification of cognitive impairment, yet Alzheimer’s disease is frequently recognized after the optimal window for intervention has narrowed.1 Early symptoms are often subtle and may be attributed to normal aging, or may be underreported due to fear or stigma, contributing to delays in diagnosis and referral.1
Early Alzheimer’s disease commonly presents with changes beyond memory loss, including word-finding difficulty, challenges with complex tasks, and reduced efficiency in managing daily responsibilities.2 These symptoms may emerge while independence in basic activities is preserved, making structured cognitive assessment an important component of routine evaluation.
Brief office-based tools and validated screening approaches can support earlier detection and help differentiate normal aging from mild cognitive impairment.3 When cognitive concerns are identified, further evaluation should not stop at screening alone. Blood-based biomarker testing is increasingly being used to support the detection of underlying Alzheimer’s pathology and can help guide decisions about specialty referral.3
Timely referral to neurology or memory specialists is essential, particularly as disease-modifying therapies continue to emerge.3 Therapies such as amyloid-targeting monoclonal antibodies, including donanemab-azbt, are being used in selected patients with early symptomatic disease and confirmed amyloid pathology.4 These approaches underscore the importance of identifying appropriate patients early in the disease course and have the potential to delay disease progression.
Referral quality is improved when documentation includes cognitive symptoms, results of brief cognitive testing, relevant laboratory evaluation to exclude reversible causes, functional history from patients or caregivers, and available biomarker results.3 Clear and structured referrals can reduce delays in specialty evaluation and improve continuity of care.
As diagnostic tools expand, earlier recognition in primary care may help ensure that patients are connected with appropriate diagnostic, therapeutic, and care-planning pathways at a stage when a broader range of management options may be available.
