Sources & Methodology
Every claim on proxi.care is grounded in peer-reviewed research, institutional reports, and clinical evidence. This page details our sourcing standards, review process, and provides a complete citation index for all referenced material.
How We Source Claims
All statistical claims, prevalence data, and medical assertions presented on proxi.care are drawn exclusively from the following source categories:
Peer-reviewed journals — including JAMA, The Lancet, PNAS, Psychosomatic Medicine, Annals of Internal Medicine, The New England Journal of Medicine, and specialty journals in gerontology, psychiatry, and psychoneuroimmunology.
Institutional reports — from the National Institutes of Health (NIH), National Institute on Aging (NIA), Alzheimer's Association annual Facts and Figures reports, and the National Alliance for Caregiving/AARP.
Systematic reviews and meta-analyses — we prioritize synthesized evidence over individual studies wherever possible. When individual studies are cited, they represent landmark findings that have been widely replicated or are seminal to the field.
Government and cost-of-care data — from the MetLife Mature Market Institute, Genworth Financial cost surveys, and federal agency publications for economic and demographic claims.
We do not cite popular press, blog posts, advocacy materials without primary sourcing, or unpublished data. Where ranges are given (e.g., "30-40% clinical depression prevalence"), they reflect the spread across multiple studies rather than a single estimate.
How Medical Claims Are Reviewed
Clinical Advisory Review
All medical claims undergo review by our clinical advisory network. Content involving specific health outcomes, biomarker data, or treatment efficacy is reviewed by qualified professionals with relevant domain expertise before publication.
No Diagnostic Claims
Proxi.care does not diagnose medical conditions, prescribe treatments, or provide personalized medical advice. Self-assessment tools on this site are educational instruments designed to encourage reflection and professional consultation — they are not clinical diagnostic instruments. All tool pages include explicit disclaimers to this effect.
Dementia Caregiver Syndrome Framework
The Dementia Caregiver Syndrome (DCS) framework presented on this site is a proposed clinical construct developed by Proxi.care. It synthesizes existing peer-reviewed evidence into a unified clinical model. While the individual health impacts it describes are well-documented in medical research, the framework itself is not a formally recognized diagnosis in any official diagnostic classification system and should be understood in that context.
Evidence-Driven Updates
When new research challenges or refines our cited findings, we update our content accordingly. We do not selectively cite evidence that supports our framework while ignoring contradictory findings. All content pages display a "last updated" indicator.
Editorial Update Process
Quarterly
Resource Pages
All resource guides, community links, and practical tool recommendations are reviewed every three months to verify accuracy, availability, and continued relevance. Broken links are removed or replaced. New resources meeting our editorial standards are added.
Annually
Data Pages
Evidence pages citing statistical claims, prevalence data, and clinical outcomes are reviewed annually against newly published research. Updates incorporate the latest Alzheimer's Association Facts and Figures, new meta-analyses, and significant single-study findings.
Monthly
Community Links
External links to support organizations, crisis lines, and community services are verified monthly. We prioritize ensuring that crisis resources remain functional and that phone numbers, URLs, and service descriptions are current.
