Lw. Welch et al., WINEGLASS CONFABULATIONS AMONG BRAIN-DAMAGED ALCOHOLICS ON THE WECHSLER MEMORY SCALE REVISED VISUAL REPRODUCTION SUBTEST, Cortex, 33(3), 1997, pp. 543-551
Confabulation is a clinically well-documented accompaniment of selecti
ve types of memory impairment, especially in brain-damaged alcoholics.
This study reports specific occurrences of visual confabulation consi
sting of spontaneous alterations of Card D of the Visual Reproduction
subtest of the Wechsler Memory Scale-Revised. The resemblance of a win
eglass was fashioned by a 90-degree rotation into a ''bowl and stem'',
observed in six of 30 brain-damaged alcoholics. There were no such in
stances in 132 other patients, including alcoholic controls, those wit
h Parkinson's Disease, temporal lobe epileptics (pre-or postsurgery),
and those with neurotoxic exposure. When asked, the subjects who ident
ified the figure as a wineglass or similar drinking instrument reporte
d that they had drawn it as originally shown to them. ''Wineglass'' co
nfabulators had shorter periods of abstinence, longer drinking histori
es and lower intellectual functioning than their brain-damaged peers o
r an alcoholic control group. These findings lend support for the asso
ciation of alcohol-related confabulation with visual, as well as previ
ously-documented verbal material among brain-damaged alcoholics.
