[Factors associated with a 1-year development in the functional autonomy of elderly persons living at home].

The purpose of the study was to examine the incidence and reversibility of disability among elderly people over one year follow-up and to determine the predictors of functional changes. The population used in this analysis consisted in 1850 subjects aged 65 and over included in the PAQUID cohort and visited again at one year follow-up. Disability was measured by Katz's scale (Activities of Daily Living or ADLs), Lawton's scale (Instrumental Activities of Daily Living or IADLs) and a mobility scale. The one year incidence of the dependency was 5.6% for ADLs, 10.8% for IADLs, and 3.3% for mobility. Being dependent at baseline was associated with an increased risk of one year mortality comprised between 3.3 and 5.3 according to the measurement scale. Recovery back to independence was frequent however, especially for ADLs (44.7%) and mobility (28.9%). Predictors of disability were: age in all scales, vision impairment and Mini Mental State Examination score for IADL and mobility scales, depressive symptomatology for ADLs, female sex and breathlessness for IADLs. Absence of cognitive impairment at baseline was associated with recovery to independence in all scales.

Instrumental activities of daily living as a screening tool for cognitive impairment and dementia in elderly community dwellers.

OBJECTIVE: To identify which Instrumental Activities of Daily Living (IADL) are related to cognitive impairment, independent of age, sex, and education; to assess the performance of an IADL score using these items in screening for cognitive impairment and dementia in elderly community dwellers. DESIGN: Survey based on the baseline interview of the PAQUID study on functional and cerebral aging. SETTING: Community survey in 37 randomly selected parishes in Gironde, France. SUBJECTS: Random sample of 2,792 community dwellers aged 65 and over (participation rate: 69%). MEASUREMENTS: Two-phase screening: (1) functional assessment, Mini-Mental State Examination (MMSE) and DSM-III criteria for dementia; (2) in DSM-III-positive patients, NINCDS-ADRDA criteria applied by a neurologist. Functional assessment: IADL scale of Lawton and Brody. Criterion standards: cognitive impairment: MMSE score lower than 24; dementia: DSM-III and NINCDS-ADRDA criteria. RESULTS: Four IADL items are correlated with cognitive impairment independent of age, sex, and education: telephone use, use of means of transportation, responsibility for medication intake, and handling finances. A score adding the number of IADL dependencies has a sensitivity of 0.62 and a specificity of 0.80 at the lowest cut-off point (score > 0) for the diagnosis of cognitive impairment. The same score at the same cut-off has a sensitivity of 0.94 and a specificity of 0.71 for the diagnosis of dementia. The prevalence of dementia (2.4%) is reduced by a factor of 12 in subjects independent for the four IADL. CONCLUSION: The four IADL score could be incorporated into the screening procedure for dementia in elderly community dwellers.

The Paquid epidemiological program on brain ageing.

Paquid is an epidemiological study designed to gather and follow-up a cohort of 3,777 elderly subjects (65 years and older) living at home. In order to study normal and pathological brain ageing, these subjects were randomly chosen in the general population of 75 communities of Gironde and Dordogne, two administrative areas of South-Western France. The subjects were interviewed at home by trained psychologists and followed-up with the same procedure at 1, 3 and 5 years after the initial data collection. The identification of the demented cases is made with a two-stage design: the first stage is a systematic screening by the psychologists with application of the DSM-IIIR criteria and the second stage consists in a confirmation of the diagnosis by a neurologist according to the NINCDS-ADRDA criteria. Paquid is complemented by the study of a random sample of 357 subjects living in institutions in Gironde.
