Age specific prevalence and incidence figures for dementia were investigated for people aged 50 or more within the Registration Network of Family Practices (RNH), a computerized registration network of 15 general practices in the Netherlands.
Point prevalence was 7.6 (95% Cl=6.2-9.0) and cumulative incidence was 2.0 per 1 000 persons per year (95% Cl=1.8-2.4).
Both prevalence and incidence increase with age and are higher in women than in men.
Dementia tends to be more frequent in people with a lower education, although this finding is not statistically significant (p=0.08).
A complex interaction exists between age and type of household, dementia being more frequent in people living with others at older age (age 80 and more) and in people living alone at younger age.
There are no arguments for a relation between dementia and a general susceptibility for disease, as estimated by the number of health problems known to the GP or between dementia and (clusters of) specific diseases.
