The NeuroCommunity Ageing Framework: A Nursing Model for Brain-Health Assessment Towards Diagnostic Justice in Minority Older Adults.

AIM(S): To propose the NeuroCommunity Ageing Framework as a nursing-centred theoretical model for integrated brain-health assessment towards diagnostic justice in minority ageing populations.

DESIGN

Discursive theoretical paper presenting a conceptual framework derived from cross-disciplinary synthesis.

METHODS

A structured theoretical synthesis integrated literature on gerontological nursing, dementia epidemiology, multidomain prevention, clinical pharmacology, family caregiving, culturally responsive care, service access and systemic factors relevant to blood-based Alzheimer's disease biomarkers.

RESULTS

The framework integrates metabolic-vascular, cognitive-clinical, pharmacological, family-caregiving, cultural-linguistic and systemic-service determinants of brain health. It positions nurses to recognise cognitive vulnerability earlier, conduct culturally informed medication review, support caregivers, address language and stigma barriers and navigate service access. Hepatic calibration is presented strictly as a hypothesis-generating research construct for future biomarker validation in multimorbid older adults, not as a clinical interpretation rule.

CONCLUSION

The framework offers a nursing-oriented model for culturally valid dementia assessment, medication safety, caregiver support and equitable service navigation.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The framework may support nurses in embedding brain-health case-finding within primary care, chronic disease and community settings.

IMPACT: The paper addresses delayed dementia recognition among minority older adults and proposes a practical nursing framework advancing diagnostic justice.

REPORTING METHOD: No specific reporting guideline directly applies to this discursive theoretical paper; it was prepared according to principles of transparent narrative synthesis.

PATIENT OR PUBLIC CONTRIBUTION: This study did not include patient or public involvement in its design, conduct or reporting.
