Sampling Method
Study Population
We implement two study designs, first a longitudinal cohort study to assess dementia incidence and second a matched case-control study for mortality, cause of death and hospitalization.
We identify individuals aged 30 years or older and registered in the current primary care practice for at least one year. Individuals are excluded if they had a prior history of dementia before study entry. For the nested case-control study, controls are matched to incident dementia patients according to sex and age (10-year age strata).
Description
Inclusion Criteria:
- We identify individuals aged 30 years or older and registered in the current primary care practice for at least one year.
Exclusion Criteria:
