Abstract:
In a group of 33 acutely ill, previously unmedicated schizophrenic inpatients, the auditory-evoked potential components N1 and P2 were assessed and related to neuroleptic response measured as improvement of the BPRS score during a two-week neuroleptic treatment. N1 latency increase was found to be predictive for a poor neuroleptic response.
