| Popis: | Confabulation is a clinically well-documented accompaniment of selective types of memory impairment, especially in brain-damaged alcoholics. This study reports specific occurrences of visual confabulation consisting of spontaneous alterations of Card D of the Visual Reproduction subtest of the Wechsler Memory Scale-Revised. The resemblance of a wineglass was fashioned by a 90-degree rotation into a “bowl and stem”, observed in six of 30 brain-damaged alcoholics. There were no such instances in 132 other patients, including alcoholic controls, those with Parkinson's Disease, temporal lobe epileptics (pre- or post- surgery), and those with neurotoxic exposure. When asked, the subjects who identified the figure as a wineglass or similar drinking instrument reported that they had drawn it as originally shown to them. “Wineglass” confabulators had shorter periods of abstinence, longer drinking histories and lower intellectual functioning than their brain-damaged peers or an alcoholic control group. These findings lend support for the association of alcohol- related confabulation with visual, as well as previously-documented verbal material among brain-damaged alcoholics. |
