The interview provided longitudinal data on sociodemographic variables (place of residence, household structure, marital status and social contact), activities of daily living, use of health and social service, health problems and medication.
Each survey has included a detailed cognitive assessment, including at least the Mini-Mental State Examination (MMSE), usually its extended version and, in the majority of interviews, the Cambridge Cognitive Exam (CAMCOG).
Those scored 23 below in the MMSE were assessed using the Cambridge Mental Disorders of the Elderly Examination (CAMDEX), designed to detect mild dementia. The CAMDEX includes a mental state examination, a psychiatric history, detailed cognitive testing, and an interview with a proxy informant.
