Structured approach to patients with memory difficulties in family practice.
Bibliographic record
Abstract
OBJECTIVE: To provide family physicians with a structured approach to patients presenting with memory difficulties. SOURCES OF INFORMATION: The approach is based on an accredited memory clinic training program developed by the Centre for Family Medicine Memory Clinic in partnership with the Ontario College of Family Physicians. MAIN MESSAGE: Use of a structured clinical reasoning approach can assist physicians in achieving an accurate diagnosis in patients presenting with memory difficulties. Delirium, depression, and reversible causes need to be excluded, followed by differentiation among normal cognitive aging, mild cognitive impairment, and dementia. Obtaining collateral history and accurate functional assessment are critical. Common forms of dementia can be clinically differentiated by the order in which symptoms appear and by how cognitive deficits evolve over time. Typically, early signs of Alzheimer dementia involve impairment in episodic memory, whereas dementia involving predominantly vascular causes might present with early loss of executive function and relatively preserved episodic memory. Frontotemporal dementia and Lewy body spectrum disorders might have early loss of executive function and visuospatial function, as well as characteristic clinical features. CONCLUSION: A clinical reasoning approach can help physicians achieve early, accurate diagnoses that can guide appropriate management and improve care for patients with memory difficulties.

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.
