Comparative Neurocognitive Functions of Schizophrenics and Temporal Lobe Epileptic Patients

347908 Introduction: Shared neuropathology hypothesis in schizophrenia and temporal lobe epilepsy has been introduced long term ago. Similar neuropathology leads to the analogous clinical features like neuropsychological features as an example. The aim of this study was to examine this hypothesis by the means of comparing neuropsychological functions in these two patient groups. Methods: Present study consisted of 28 DSM_IV_TR schizophrenics and 29 patients with temporal lobe epilepsy recruited from Roozbeh, Razi and khatamolanbia hospital in Tehran by convenient sampling method. SCID in schizophrenic group and EEG, MRI in epileptic patients were taken in regard to diagnostic determination. Neuropsychological tests were taken later. Package of neuropsychological tests consisted of Modified Wisconsin Card Sorting Test, Stroop Color- Word Test, Logic Memory, Visual Reproduction and Digit Span subscales of Wechsler Memory Scale- Revised and Block Design, Vocabulary and Symbol Digit subscales of Wechsler Adult intelligence Scale- Revised. Results: there was no significant difference in two groups of patients with respect to demographic and clinical )Age, Depression, premorbid function and duration( variables. Analysis of MANOVA was taken to compare two groups of patients in neuropsychological functions. The results revealed no significant differences between schizophrenics and temporal lobe epileptic patients except for Symbol Digit subscale that was significantly lower in schizophrenic group (p < 0.05). Conclusion: the result of current study is consistent with shared neuropathology hypothesis in schizophrenia and temporal lobe epilepsy. Profile of neuropsychological functions in both groups was generalized and beyond temporal lobe. Declaration of Interest: None
