Bridging Dementia Care in Japan: The Emerging Role of General Medicine Physicians
Bibliographic record
Abstract
As global populations age, dementia has become a major public health challenge that warrants sustainable, person-centered, and community-integrated models of care. In Japan, the recent introduction of board-certified general medicine (GM) physicians, trained across both family medicine and hospital general medicine, has created an opportunity to strengthen dementia care through improved continuity and coordination. This narrative review conceptually examines the emerging role of GM physicians within Japan's Community-Based Integrated Care System and compares this evolving model with dementia care structures in the United States, the United Kingdom, and Canada. By synthesizing policy documents and published literature, this review outlines how GM physicians can serve as integrative actors bridging outpatient and inpatient care, collaborating with dementia specialists, Initial-phase Intensive Support Teams, and Community-based Comprehensive Support Centers to enhance person-centered support throughout the disease trajectory. While empirical outcome data remain limited, this conceptual framework highlights potential contributions of GM physicians to early detection, care transitions, and interdisciplinary collaboration in dementia care. However, challenges persist, including training variability, workforce shortages, and systemic fragmentation. By situating Japan's experience within an international context, this review provides a conceptual basis for future empirical studies and policy development aimed at strengthening generalist-led dementia care in aging societies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
