title: Visual-perceptual abnormalities in delusional misidentification.
abstract: Delusional misidentification syndromes are often found in conjunction with visual-perceptual abnormalities. These abnormalities appear to be independent of visual hallucinations and are illusory in nature. A case of delusional misidentification with visual-perceptual abnormalities is presented. Cognitive and visual phenomenology suggests that careful recording of visual abnormalities may shed light on the relation between delusional misidentification and abnormal visual cognition.
