Abstract

Topographic differences in flash/pattern shift VEP data are evaluatedin paranoid (n : 38), disorganized (n :23) and residual (n : 23) schizophrenic subtypes and compared to normal controls. Increased early P-1 and a restricted diffusion of the late P-2 responses suggest dopaminergic over- and cholinergic underactivity in paranoid and residual schizophrenia. A distinctive pattern N-145 reflects well-preserved attentional resources in the paranoid subtype. Latency increase and amplitude decrease of the pattern N-145 concur with abnormal antisaccades documented in disorganized behaviour. VEP-data might help differentiate between schizophrenic subtypes.
