Cambridge City over-75s Cohort study

Initiatives -
The design started as a mechanism to detect people in the earliest stages of dementia, not yet perceived by their families, who could then be followed and in whom different patterns of care might be investigated. The focus in later years shifted to quality of life issues of “older old” people near the end of life.

Follow Up
Each follow-up survey has included the Cambridge Cognitive Examination (CAMCOG). Sub-samples have had detailed psychiatric assessment using the Cambridge Diagnostic Examination for the Elderly (CAMDEX) interview, detailed neuropsychological assessment and additional tests. Longitudinal data are also available on socio-demographic variables (e.g. change of residence, household structure, change in marital status, social contact), activities of daily living, use of health and social services, health problems and medication, self-rated health and subjective well-being.
