“…These data were taken from the Maastricht Aging Study 18 which comprised several studies of the biomedical and psychological determinants of cognitive ageing. The core project was a large crosssectional study of 2000 healthy individuals aged 24-81 years who were followed up for 12 years with regard to health characteristics and neurocognitive status.…”

“…The study population consisted of 1823 participants, aged 24-81 years at baseline, and comprised four demographically identical panels, each stratified for age, sex, and general ability level. A detailed description of the MAAS study design can be found elsewhere [12,14]. The present study was carried out in one single panel of the MAAS study, consisting of 470 participants at baseline, of whom 301 individuals participated in the 12-year reassessments.…”

a b s t r a c tDepressive symptoms in the community have a considerable impact on quality of life. Although longchain polyunsaturated fatty acids (LCPUFA) have frequently been implicated in depressed mood, their relationship with quality of life has scarcely been investigated.This study examined the cross-sectional associations between fish consumption and plasma phospholipid LCPUFA status on the one hand, and quality of life, as measured by the Short Form 36 questionnaire, on the other in a population-based sample. The mental health component of quality of life was not associated with LCPUFA status or fish consumption. Fish consumption showed a positive association with physical well-being, which remained significant after correction for LCPUFA status, suggesting that the relationship between fish consumption and physical well-being is independent of the LCPUFA content of fish. These findings indicate that fish consumption may serve as a proxy for a healthy lifestyle or a favorable nutritional status, which is reflected in better quality of life.

A large sample of older participants of the Maastricht Aging Study (MAAS) were compared to drop-outs at the 3-year follow-up with respect to socio-demographic, health, and cognitive characteristics. In addition, the impact of selective drop-out on measures of cognitive change was examined. To this end, hypothetical scores were estimated for drop-outs by using single and multiple imputation methods. Of the initial sample of 539 subjects, aged 49 years and older at baseline, 116 (22 %) did not return for the follow-up ( n ϭ 32 had died, n ϭ 84 refused participation). Drop-outs who refused to participate in the follow-up were more often women, had lower educational levels, and had lower baseline scores on neurocognitive tests. Follow-up drop-outs who had died were more often men, older, and had a poorer performance on cognitive tests than the follow-up participants. Although follow-up participants and drop-outs differed in terms of socio-demographic and cognitive characteristics, attrition appeared to have little effect on the estimates of cognitive change.

The Relation Between Morbidity and Cognitive Performance in a Normal Aging Population

Abstract: Existing morbidity as a whole contributes only modestly (up to 3.5%) to total variance in cognitive function. However, some specific, relatively common diseases of the elderly, such as diabetes and chronic bronchitis, may aggravate the age-related decline in cognitive ability.
