Cognition and daily activities in a general population sample aged +55.

We tested the association of individual cognitive domains measured with the Mini-Mental State Examination (MMSE) and disability. Cross-sectional study in a population-based cohort aged ≥55 years (n = 4,803). Sample was divided into two groups: individuals with cognition within the normal range (CNR) (n = 4,057) and those with cognitive impairment (CI) (n = 746).

Reliability and validity of the Spanish version of the IDEAL Schedule for assessing care needs in dementia: Cross-sectional, multicenter study.

Objective: The IDEAL Schedule was developed for staging "care needs" in patients with dementia. We here aim to validate the Spanish version, further test its psychometric properties and explore a latent construct for "care needs".

Methods: A multicenter study was done in 8 dementia care facilities across Spain.

Depression and incident Alzheimer disease: the impact of disease severity.

Objectives: To test the hypothesis that clinically significant depression (particularly severe depression) increases the risk of Alzheimer's disease (AD).

Methods: A longitudinal, three-wave epidemiologic study was implemented in a sample of individuals aged 55 years and older (n = 4,803) followed up at 2.5 years and 4.

Usefulness of 2 questions about age and year of birth in the case-finding of dementia.

Objective: To test the hypothesis that the efficacy of 2 simple questions commonly used in clinical practice, asking the age and year of birth of individuals, will be satisfactory to rule out cases of dementia.

Design: Population-based, longitudinal, prospective study focused on the incidence of dementia. In the baseline, a 2-phase procedure for identifying cases and noncases of dementia was implemented.

Non-cognitive psychopathological symptoms associated with incident mild cognitive impairment and dementia, Alzheimer's type.

Objective: To test the hypothesis that specific psychopathological non-cognitive symptoms are associated with incident mild cognitive impairment (MCI), while different symptoms are associated with incident dementia of Alzheimer's type (DAT).

Methods: A representative community sample of 4,803 individuals aged 55+ years was interviewed in a two-phase screening, in Wave I or ZARADEMP I. This is the baseline, cross-sectional study of the ZARADEMP Project, a longitudinal study to document incidence and risk factors of dementia.

Somatic and psychiatric comorbidity in the general elderly population: results from the ZARADEMP Project.

Objective: In a representative sample of the elderly population in a southern European city, we tested the hypothesis that there is an association between general somatic and general psychiatric morbidity.

Methods: A stratified random sample of 4803 individuals aged > or =55 years was selected for the baseline study in the ZARADEMP Project. The elderly were assessed with standardized Spanish versions of instruments, including the Geriatric Mental State (GMS)-AGECAT.
