Confrontation naming deficit in dementia of depression
Abstract
Unlike patients with irreversible dementia, elderly depressed patients with cognitive impairment are thought to have relatively preserved recognition, memory, and language abilities. To test this hypothesis, the authors compared memory and naming performance in elderly hospitalized patients with major depression alone, reversible dementia of depression, or irreversible dementia. All patient groups performed worse than nondemented, nondepressed control subjects on memory tasks. Patients with dementia of depression performed worse than depressed patients with normal cognition on tests of free recall, delayed recall, and verbal delayed memory but not on tests of delayed visual memory. Patients with dementia of depression and patients with irreversible dementia were severely compromised in both speed and accuracy on the confrontation naming task.
