Eye tracking accuracy, which has been found to be impaired in
schizophrenic patients and their relatives, was assessed in 26 patients
with schizotypal personality disorder, 17 control subjects with other
non-schizophrenia-related personality disorders, 29 normal control
subjects, and 44 schizophrenic patients. Both schizotypal and schizophrenic
patients, but not control subjects with other personality disorders,
demonstrated significantly more impaired tracking than the normal control
subjects. These results suggest that patients with clinically defined
schizotypal personality disorder may be biologically related to
schizophrenic patients as part of a spectrum of schizophrenia-related
disorders.Abstract Teaser
