picture sign
   A term used to denote a misidentification syndrome in which the affected individual is under the impression that persons seen in a photograph are actually present in external, three-dimensional space. This impression may be so powerful that the affected individual speaks to the portrayed individuals or attempts to put food into their mouths. The picture sign is a * cognitive illusion described predominantly in elder persons acquainted with *visual hallucinations or * illusions. Etiologically, the picture sign is associated primarily with Alzheimer's disease and other types of dementia. Two related phenomena are the *magazine sign and the *TV sign.
