  1. Depressive symptoms and cognitive decline in nondemented elderly women : A prospective study.

    Article - En anglais

    Background 

    The association between depressive disorders and subsequent cognitive decline is controversial.

    We tested the hypothesis that elderly women (aged 65 years and older) without dementia but with depressive symptoms have worse cognitive function and greater cognitive decline than women with few or no symptoms.

    Methods 

    As part of an ongoing prospective study, we evaluated 5781 elderly, mostly white, community-dwelling women.

    Women completed the Geriatric Depression Scale short form.

    Three cognitive tests-Trails B, Digit Symbol, and a modified Mini-Mental State Examination-were administered at baseline and approximately 4 years later.

    Baseline, follow-up, and change scores for the cognitive tests were analyzed by analysis of covariance and Kruskal-Wallis analysis ; the odds of cognitive deterioration (>=3-point decline on the modified Mini-Mental State Examination) were determined by logistic regression.

    Results 

    At baseline, 211 (3.6%) of the women had 6 or more depressive symptoms.

    Only 16 (7.6%) of these women were receiving antidepressant medication.

    Increasing symptoms of depression were associated with worse performance at baseline and follow-up on all 3 tests of cognitive function (P<. 001 for all comparisons).

    For example, the baseline Digit Symbol score (mean ±SD) was 45.5 ± 10.7 among women with 0 to 2 symptoms of depression, 40.3 ± 10.7 for women with 3 to 5 symptoms, and 39.0 ± 11.3 for women with 6 or more symptoms. (...)
