The prediction of abnormal evoked potentials in schizophrenic patients by means of symptom pattern
HB Andrews, AO House, JE Cooper and C Barber
The case notes of 23 schizophrenic patients who participated in a study of
somato-sensory cortical evoked responses were examined for descriptions of
the clinical features of their mental state at the time of first illness or
most recent relapse. A comparison of syndrome scores derived from Present
State Examination with those derived from case notes showed that the latter
was a reliable method of mental state description for the purposes of this
study. A group of syndromes similar to that described in electrodermal
research was identified from the case note review and found to be highly
correlated with the presence of an abnormal response in the somato-sensory
evoked potentials study.
