TODO - Delusional misidentification syndromes (DMSs) and schizophrenia are
strongly associated, since the former occur predominantly in the context
of paranoid schizophrenia. However, the possible underlying
neuropsychological relationships between DMSs and paranoid schizophrenia
have not been thoroughly investigated. The aim of the present study was
to investigate whether DMSs in paranoid schizophrenia are associated
with a distinct neuropsychological substrate indicative of differential
bilateral frontal and right hemisphere dysfunction. We compared two
matched groups of paranoid schizophrenic patients with (N=22) and
without (N=22) DMS(s) on a battery of neuropsychological tests assessing
mainly frontal and right hemisphere functions. No statistically
significant differences were detected between the two groups. Our
findings are indicative of a bilateral frontal and right hemisphere
dysfunction of equal severity in both DMS and non-DMS patients with
paranoid schizophrenia. (C) 2008 Elsevier Inc. All rights reserved.
