Strategies for Supporting Early Diagnosis and Implementation of Amyloid-Targeting Therapies in Alzheimer Disease

Dr Nair introduces a new video series surrounding identification of and key treatment strategies for Alzheimer disease.

Panelists discuss how health care institutions employ comprehensive screening protocols for Alzheimer disease, including cognitive assessments, biomarker testing, and regular monitoring of at-risk populations, to facilitate early symptom identification and timely diagnosis that enables prompt intervention and improved patient outcomes.

Panelists discuss how health care institutions have established structured care pathways for nonspecialist providers to evaluate mild cognitive impairment and mild dementia, incorporating validated questionnaires, standardized screening protocols, and clear referral guidelines to ensure consistent assessment across diverse clinical settings.

Panelists discuss how significant knowledge gaps among nonspecialist providers—particularly regarding differential diagnosis, interpretation of cognitive assessments, and awareness of treatment options—are being addressed through targeted educational initiatives, embedded clinical decision support tools, and collaborative care models to enhance understanding of early Alzheimer diagnosis and treatment importance.

Panelists discuss how selecting an optimal combination of screening assessments for Alzheimer disease requires careful consideration of test sensitivity, specificity, accessibility, cost-effectiveness, implementation feasibility, and alignment with patient populations and health care resource constraints.

Panelists discuss how overcoming barriers to effective Alzheimer disease cognitive screening requires addressing multiple challenges including time constraints in clinical settings, inadequate reimbursement models, limited provider training, integration of screening tools into existing workflows, and patient concerns about diagnosis implications.

Panelists discuss how health care institutions are leveraging strategic referral networks and telemedicine technologies to bridge geographical barriers, connect rural patients with specialized dementia care, establish hub-and-spoke models with community partners, and implement virtual cognitive assessments to dramatically improve both access and quality of care for patients with Alzheimer disease in underserved areas.

Panelists discuss how amyloid-targeting therapies for Alzheimer disease represent a breakthrough drug class that works by binding to and removing beta-amyloid plaques through various mechanisms, demonstrating modest cognitive decline reduction in clinical trials while presenting safety considerations including amyloid-related imaging abnormalities (ARIA), infusion reactions, and the need for careful patient selection and monitoring protocols.

Panelists discuss how clinicians should interpret Clinical Dementia Rating-Sum of Boxes (CDR-SB) score changes by correlating numerical shifts with meaningful real-world outcomes, considering both the statistical significance and clinical meaningfulness of changes, recognizing that even modest improvements may represent significant functional preservation for patients, and contextualizing these changes within individual patient circumstances, disease trajectory, and impact on quality of life.

Panelists discuss how ideal candidates for amyloid-targeting therapy typically present with biomarker-confirmed early-stage Alzheimer disease, demonstrate positive amyloid PET scans or CSF biomarkers, exhibit mild cognitive impairment or mild dementia, lack contraindications such as significant cerebrovascular disease or anticoagulant use, have adequate support systems for monitoring and managing potential adverse effects, and would benefit from comprehensive pretreatment evaluations including brain MRI and APOE genotyping.

Panelists discuss how hesitancy in prescribing amyloid-targeting therapies stems from multiple factors including concerns about ARIA adverse effects, modest clinical efficacy data, high treatment costs and limited insurance coverage, logistical challenges of regular infusions and monitoring, infrastructure requirements for specialized imaging, uncertainty about long-term benefits, and the need for careful patient selection within appropriate disease stages.

Panelists discuss how effective communication about amyloid-targeting therapies requires transparent discussions of modest cognitive benefits alongside potential risks, particularly events related to amyloid-related imaging abnormalities (ARIA), while addressing practical considerations including treatment burden, infusion center logistics, monitoring requirements, costs, insurance coverage, and caregiver involvement to help patients and families make fully informed decisions aligned with their values and circumstances.

Panelists discuss how treatment continuation decisions for amyloid-targeting therapies involve comprehensive assessment of multiple factors including cognitive and functional changes measured through standardized tools, occurrence and severity of adverse events, treatment adherence capabilities, impact on patient/caregiver quality of life, disease progression rate, emerging safety signals, and ongoing dialogue about evolving treatment goals and expectations.
