Evaluating the Effects of Experiencing Virtual Reality Simulation of Psychosis on Mental Illness Stigma, Empathy, and Knowledge in Medical Students.

Objectives: Applying technologies such as virtual reality (VR) in education has gained popularity especially in comprehending abstract and subjective phenomena. Previous studies have shown that applying a virtual reality simulation of psychosis (VRSP) is useful in increasing knowledge and empathy toward patients. Here, the efficacy of using VRSP in altering stigma, empathy and knowledge as well as side effects have been assessed in medical students in comparison with the routine education (visiting the patients). Method: After attending one session of lecture about positive psychotic symptoms, medical students were allocated to two groups: experiencing one session of VRSP or visiting patients under supervision as routine practice in the ward. Before and after the first session and after the second one, questionnaires of knowledge, empathy and stigma were filled by students. Finally, the results were compared in two groups. Results: Both interventions were effective in reducing stigma as well as increasing knowledge and empathy toward patients with psychotic experiences. VRSP could significantly reduce stigma and increase knowledge and empathy compared with the traditional visiting patients under supervision. The side effects were minimal and ameliorated right after the experience. Conclusion: VRSP is an effective tool in decreasing stigma and increasing empathy and knowledge of the students and can be incorporated in psychiatric education with minimal side effects.

Effects of memantine added to risperidone on the symptoms of schizophrenia: A randomized double-blind, placebo-controlled clinical trial.

The "glutamate hypothesis of schizophrenia" has changed attitudes in the development of new medications. This study aimed to evaluate the effects of 20mg of memantine per day (as a NMDA receptor antagonist) added to risperidone among male patients with schizophrenia. In a randomized placebo-controlled, double-blind clinical trial, 46 adult male patients with schizophrenia were evaluated in both intervention and control groups at weeks 0, 6 and 12. The positive and negative symptoms scale and the mini mental status examination were used to assess positive, negative and cognitive symptoms and general psychopathology. The mean age of the patients was 44.8 for the intervention group and 45.3 for the control group, and the mean times since diagnosis were 23.5 and 25.7 years in the intervention and the control group, respectively. Positive and general psychopathologic symptoms showed no significant differences between the two groups at baseline or after treatment; while negative symptoms improved significantly in the intervention group at week 12. Cognitive function was also significantly improved in the intervention group at weeks 6 and 12. Memantine is supported as an effective adjunct treatment to improve negative and cognitive symptoms in patients with schizophrenia.

Investigating the Attitude of Graduate Psychiatrists towards Objective Structured Clinical Examination (OSCE) and Conventional Clinical Interview Examination.

OBJECTIVE: In the present study, we investigated the attitude of psychiatrists who graduated in 2002-2009 towards Objective Structured Clinical Examination (OSCE) and conventional clinical interview examination (Individual Patient Assessment). METHOD: We studied 134 psychiatrists graduated; half of whom were examined with conventional clinical interview and the others with OSCE. A questionnaire was prepared by a specialist workgroup to assess the participants' attitude towards the exams. The questionnaire was initially examined in a pilot study. The findings of the questionnaire were used to assess the graduates' attitude towards each examination, as well as to compare the examinations. RESULTS: The OSCE group indicated a significantly more positive attitude compared to the conventional group (p = 0.03). Furthermore, the OSCE group believed the role of theoretical knowledge (p = 0.01) and pre-test practice (p = 0.03) to be significantly greater for success compared to the other group. The structure of OSCE was reported to be superior to conventional examination in terms of fairness and homogeneity (p = 0.004). First participation in exam (p = 0.04) and ultimate success in the exam (p = 0.009) were predictors of graduates' attitude. CONCLUSION: Based on examinees 'attitudes, OSCE may be a more appropriate choice for graduation examinations of psychiatry compared to the conventional clinical interview examination.

Topiramate Add-on Lithium Carbonate for Treatment of Acute Mania.

OBJECTIVE: The purpose of this study was to evaluate the effect of adjunctive topiramate in treating acute mania. METHODS: In this study which was a double-blinded randomized clinical trial, 46 bipolar patients in manic episode, were treated with lithium carbonate and topiramate versus lithium carbonate and placebo and treatment responses were assessed by Young Mania Rating Scale (YMRS) weekly. RESULTS: In both intervention and control groups, YMRS score had significant decline after 8 weeks(p < 0.001), but there was no statistically significant difference between the two groups (p = 0.419). The highest score decline was after two weeks. YMRS score at baseline did not have statistically significant difference between the intervention and control groups (p = 0.709). CONCLUSIONS: This study failed to show antimanic efficacy of adjunctive topiramate in the treatment of those with acute manic. DECLARATION OF INTEREST: None.

Sensation seeking behavior among schizophrenics.

OBJECTIVE: To compare sensation seeking between schizophrenic patients (and clinical subtypes of schizophrenia) according to criteria of DSM-IV-TR; and a healthy control group. Two hypotheses were assumed: 1. Sensation seeking in the control group is higher than schizophrenic patients. 2. The levels of sensation seeking are different among clinical subtypes of schizophrenia. METHODS: The sample comprised a study group of 69 schizophrenic inpatients at Raazy Psychiatric Center, Tehran, Iran in 2005 (10 males and 10 females for each of paranoid, undifferentiated and residual subtypes, and 9 males from disorganized subtype), and 50 randomly selected healthy people, the control group. To measure sensation seeking, the Zuckermann Sensation Seeking Scale, a 41-item questionnaire form, was used after evaluating its validity and reliability. After obtaining a weak or negative correlation, we omitted 9 questions, so that finally a 32-item questionnaire with highest reliability (Cronbach`s alpha = 0.64), remained and was utilized. We used descriptive statistical methods and calculation of statistical indices, and Student t-test for independent groups to evaluate the research hypotheses. RESULTS: The first hypothesis was confirmed at a 99% significance level. The second hypothesis was rejected at a 95% significance level. CONCLUSION: We found a definite correlation between schizophrenia and a low level of sensation seeking. Accordingly, and since sensation seeking (as a part of temperament) has a strong genetic component, a low level of sensation seeking is probably an existing feature of schizophrenia. Assessing sensation seeking in high-risk populations (children or the siblings of schizophrenics) could be a practical attempt at prevention or immediate treatment of schizophrenia.
