Somatosensory evoked potential correlates of schizophrenic subtypes identified by the Millon Clinical Multiaxial Inventory.
Evoked potentials (EPs) of schizophrenic patients differ from those of normal controls and some other diagnostic groups, but EP measurements of the comparison groups often overlap considerably. This suggests that schizophrenics are heterogeneous with respect to EP measurements and that additional methods for clinical subtyping are needed to account for the heterogeneity. This study used criteria based on the Millon Clinical Multiaxial Inventory to partition 20 patients, who were all schizophrenic by three diagnostic systems, into two subgroups. Somatosensory EP measurements of these two subgroups differed, suggesting that neurophysiological heterogeneity within the total sample of schizophrenics was associated with corresponding heterogeneity of the clinical features in the Millon scales.
