[Codex and MMSE: what to choose?]

The objective of this study was to compare in general practice, patients aged 65 years and over: the MMSE, screening tools for cognitive disorder recommended by the HAS and the Codex.53 patients were included between June and October 2017 at La Charmille general practice in Limpiville in rural areas during an observational study. Patients over 65 years of age were included following a consultation with their general practitioner. The MMSE and the Codex were compared on their results, intrinsic variables, the time of handover. Geriatric comorbidity factors are compared between groups of patients "with" and "without" cognitive disorders detected.Of the 53 patients, 94% CI 95% [4.10; 20.25] had cognitive impairment, at an average age of 74.15 years. The predominance is female with 30 patients (57%). The passage time of the Codex is on average 1min 43s, significantly faster (p = 4,29*10Codex appears to be a rapid, reliable, reproducible cognitive impairment screening tool adapted to the general practice consultation format. An important axis to work, awareness, education of doctors at the university and continuing education on the screening and management of dementia syndromes and fragility.
