Abstract

Objective Cognitive impairment in late-life depression (LLD) is prevalent, disabling, and persists despite the remission of depressive symptoms. This article characterizes neuropsychologic functioning during remission in LLD. Methods The authors examined longitudinal performance on a comprehensive neuropsychologic battery in 56 nondemented subjects age 60 or older who initially presented with an episode of nonpsychotic unipolar major depression and 40 nondemented, age- and education-equated comparison subjects with no history of depression. Subjects were assessed at baseline (in a depressed state) and one year later (when remitted). Results After one year, 45% of the LLD subjects were cognitively impaired despite remission of depression. Visuospatial ability, information-processing speed, and delayed memory were most frequently impaired; 94% of the patients who were impaired at baseline remained impaired one year later. Twenty-three percent of the patients who were cognitively normal while depressed developed impairment one year later. Conclusions Most older individuals who are cognitively impaired during a depressive episode remain impaired when their depression remits. In addition, a substantial proportion of older depressed individuals who are cognitively intact when depressed are likely to be impaired one year later, although their depression has remitted.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
