Cognitive Impairment Without Dementia in Older People: Prevalence, Vascular Risk Factors, Impact on Disability. The Italian Longitudinal Study on Aging

OBJECTIVES: To investigate prevalence of “cognitive impairment, no dementia” (CIND) in the Italian older population, evaluating the association with cardiovascular disease and the impact on activities of daily living (ADL). CIND may provide pathogenic clues to dementia and independently affect ADL. DESIGN: Cross‐sectional examination in the context of the Italian Longitudinal Study on Aging. SETTING: Random population sample from eight Italian municipalities. PARTICIPANTS: A total of 3425 individuals aged 65–84 years, residing in the community or institutionalized.
