Objectives. This study provides an overview of Alzheimer’s disease and other dementias (ADOD) in mainland France using existing databases and initiates a discussion on the monitoring methods that should be implemented based on medical-administrative databases and medical causes of death. Methods. The data cover two years (2007 and 2010) and are drawn from the health insurance databases on long-term conditions (ALD), hospitalizations (stays and patients), and death certificates. The selection algorithm corresponds to the ICD-10 codes for MAAD (G30, F00, F01, F03). Results. In 2010, 316,115 people were enrolled in ALD15; 228,190 were hospitalized with a MAAD, and 54,291 died with a MAAD. Between 2007 and 2010, despite the short study period, the number of patients with ALD15 increased by 14.6%, the number of people hospitalized with AD or related dementias increased by 23.6%, and the number of deaths with AD or related dementias increased by 13.9%. Conclusion. These results highlight the considerable and growing burden of Alzheimer’s disease and related dementias on society. They further confirm the value of analyzing medical-administrative databases—ideally by cross-referencing them—and medical causes of death in monitoring these conditions, as a complement to cohort studies.
