Background & Rationale

Alzheimer’s disease and related dementias (ADRD) demand coordinated, translational approaches. The South Carolina Alzheimer’s Disease Research Center (ADRC) integrates neuroimaging–neurology, health sciences/public health, molecular biology, and engineering using a recurring loop adapted from the University of South Carolina’s Cancer Prevention and Control Program: Discovery → Development → Delivery → Dissemination. This model couples scientific rigor with equity and real-world impact.

The Circular Loop Model

1. Discovery: Identify candidate cellular/molecular biomarkers; define imaging signatures for prodromal ADRD; generate hypotheses from statewide data.
2. Development: Validate biomarkers and imaging metrics; prototype wearables and digital assessments; design protocols and cross-disciplinary pilot projects.
3. Delivery: Implement early-diagnosis pathways, remote monitoring, and caregiver support tools; integrate equity-minded recruitment and mentoring.
4. Dissemination: Share findings via publications, data dashboards, clinician training, and community engagement; feed insights back to Discovery.

Disciplinary Roles (Illustrative)

• Neuroimaging–Neurology: Early detection signatures; harmonized acquisition; longitudinal change tracking.
• Molecular Biology: Biomarker panels (neuroinflammation, proteostasis); target discovery for trials.
• Engineering: Wearables and edge analytics for real-time function; secure data pipelines.
• Health Sciences & Public Health: Population-level analyses of caregiver burden, access, and inequities; implementation science.

Mentorship, Equity, and Infrastructure

The ADRC supports structured mentorship, shared infrastructure (data cores, biobanks, imaging), and cross-disciplinary pilots. Focus areas include inclusive recruitment, rural access, caregiver outcomes, and statewide data linkage to reduce disparities.

Implications

By organizing teams around a loop rather than linear pipeline, the ADRC accelerates iteration: early signals from community practice and caregivers rapidly inform new hypotheses, device refinements, and clinical workflows. Institutions seeking to scale ADRD research can adapt this playbook to align discovery with delivery and measurable community benefit.

How Deep Sweeps Work in Practice

When a curator initiates a Deep Sweep, the analysis extends beyond a single paper’s abstract. The goal is to position each study within the continuum of evidence—upstream, laterally, and downstream—so the output reflects not only what was found, but why it matters.

• Upstream — Foundational Work: Earlier discoveries shaping the study design (e.g., meta-analyses, biomarker/imaging correlations, methodological standards such as PRISMA and MDS criteria).
• Lateral — Peer Comparisons: Companion trials or cohort papers in the same time window (e.g., Neurology, Nature Aging) used to verify effect sizes and methodological choices.
• Downstream — Translational & Clinical Implications: Guidelines, reviews, or expert commentary citing the work, indicating whether practice is already adapting.

A full Deep Sweep typically provides:

• Primary study synthesis (the DOI you provide).
• Two to three contextual citations (related trials/meta-analyses).
• One translational source (guideline, commentary, or expert review).
• One data visualization showing trend or comparative magnitude (embedded or appended to academic standards).

This embedded structure meets academic reporting norms while keeping Voice of Health articles clear, concise, and clinically relevant.

Limitations & Notes

• Framework article (programmatic) rather than a single efficacy trial; outcomes vary by site capacity.
• Requires governance for data standards, privacy, and attribution across teams.
• Equity aims depend on sustained resources, CRC staffing, and community partnerships.
