Disease duration had no influence on the results.Ĭonclusion: there is a link between abnormal ABRs and auditory hallucinations in schizophrenic patients that indicates dysfunction and abnormal asymmetry of auditory pathways in these patients.Īleman, A., & Laroi, F. Latencies of waves III and V and IPL of III-V were significantly prolonged on the left side. Results: 39 patients and 35 controls were included. Chi squire and independent t tests were applied for statistical analysis. Then, ABR recorded from all participants and the latencies of waves I, II, III, IV, V and inter-peak latencies (IPL) of waves I-III, III-V were analyzed on both sides. Scale for assessment of positive symptoms (SAPS) was used for rating the severity of hallucinations. Methods: schizophrenic patients with auditory hallucinations and age and sex matched healthy non-relative controls were recruited in this case-control study. So, the aim of this study is to evaluate auditory pathways of schizophrenic patients using auditory brainstem responses (ABR). Abstractīackground: although the exact pathogenesis of auditory hallucinations is not yet known, some suggested the impairment of perception and processing of auditory information as a possible explanation.
