A total of 870 individuals from a ruralregion and 2,119 individuals from an urban region of Valladolid, Spain, were involved. The seven-minute screenneurocognitive battery was used in the screening phase. A control group was included.Results: A total of 2,170 individuals aged 65 to 104 years (57% women) were assessed. There were 184 subjectsdiagnosed with dementia. The crude prevalence was 8.5% (95% CI: 7.3-9.7). Age- and sex-adjusted prevalence was5.5 (95% CI: 4.5-6.5). Main subtypes of dementia were: Alzheimer’s disease (AD) 77.7%, Lewy Body disease, 7.6%and vascular dementia (VD) 5.9%. Crude prevalences were 6.6% (AD), 0.6% (Lewy Body disease), and 0.5% (VD).Dementia was associated with age (OR 1.14 for 1-year increase in age), female sex (OR 1.79) and the absence offormal education (OR 2.53 compared to subjects with primary education or more).Conclusion: The prevalence of dementia in the study population was lower than the most recent estimates forWestern Europe. There was a high proportion of AD among all dementia cases and very low prevalence of VD. Oldage, female sex, and low education level were independent risk factors for dementia and AD.
