Objectives. To know the prevalence of dementia and its subtypes in our area. Patients and methods. Epidemiological study, doortodoor, double phase, in which all noninstitutionalized subjects from 8 rural villages aged 70 and more were selected. The general physicians and nurses, previously trained, administered the Mini Cognitive Examination (MCE) in the first phase. All subjects to whom cannot been administered MCE due to illness or sensorial deficit, all subjects under the cutoff point and a similar number of subjects randomized among the ones over the cutoff point, get through the second phase in which a clinical psychologist and a neurological trained physician administered the Cambridge Mental Disorders of the Elderly Examination (CAMDEX). All diagnosis were done under CAMDEX criteria. Results. A total of 1,460 subjects participated. The prevalence of dementia was 16.3% (14.418.2). The dementia Alzheimer type ratio was 40.76% (34.547), the vascular dementia was 38.24% (32.144.4), the mixed dementia was 11.7% (7.715.8) and the secondary dementia was 9.2% (5.512.9%). The logistic regression confirms that age and female sex are dementia risk factor. Conclusion. In our geographical area a very high prevalence of dementia is found.
