Cognitive performance in tests sensitive to frontal lobe dysfunction in the elderly depressed
Abstract
The paper reports the profile of impairment across a variety of cognitive functions with special emphasis on tests sensitive to frontal lobe dysfunction, in 24 elderly depressed patients during and on recovery from mood disorder, compared with 15 age- and sex-matched controls. Traditional neuropsychological tests and a recently developed battery of computerized tests (CANTAB) were used. Impairments were found in the depressed group compared to controls and to themselves on recovery across all domains examined. The depressed group showed deficits on visuospatial recognition memory, attentional shifting at the extra-dimensional shift stage and in measures of both processing and motor speed without impaired accuracy in a visual search task. Impairments were also found on a planning task with disproportionately increased numbers of moves needed for more difficult problems and evidence of both slowed motor response and increased processing time once the task was commenced. Performance on recovery improved across all tasks. Comparisons were made with the performance of patients suffering from dementia of the Alzheimer type (DAT) and Parkinson's disease on similar tests. Response latencies in test performance were found to correlate with the number of episodes of depression suffered and with ventricular size on CT scan, as measured by computerized planimetry. On recovery, residual depression scores correlated with latency of test performance and with ventricular brain ratio. The results, thus, show that depression in the elderly is associated with a significant degree of deficit on tests sensitive to frontostriatal dysfunction. Some of the deficits appear specific to depression and some do not remit following clinical recovery. However, these impairments have to be interpreted in the context of a broad profile of cognitive deficit.

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.
