背景脑电图是一种常见的要求测试的病人参加精神科服务，主要是为了调查可能的器质性脑综合征引起的行为变化。目的评估转介脑电图从精神科服务与其他来源的比较。我们确定哪些临床因素与异常EEG的患者转介精神sources.Methods在1年的时间内进行回顾性分析EEG的要求。精神病患者的转诊原因进行了分析，并从精神病服务后的EEG结果进行了审查，其中91（6.2%）是从精神科转介的患者进行了审查。神经科转诊的异常脑电图检出率为27%，精神科转诊的异常脑电图检出率最低，为17.6%（p < 0.1）。在精神科转诊的患者中，发现异常EEG的唯一重要预测因素是已知的癫痫病史（p < 0.001）、服用氯氮平（p < 0.05）和可能的惊厥发作（RR = 6.51）。53例患者的随访数据并没有显示出显着的临床影响，EEG结果对患者management.Conclusions许多患者被称为EEG从精神病学的来源，尽管一个相对较低的指数怀疑一个有机的大脑疾病，转诊记录的原因，与一个不足为奇的低临床产量。版权所有（c）2006约翰威利父子有限公司。
Background The EEG is a commonly requested test on patients attending psychiatric services, predominantly to investigate for a possible organic brain syndrome causing behavioural changes. Aims To assess referrals for EEG from psychiatric services in comparison with those from other sources. We determine which clinical factors were associated with an abnormal EEG in patients referred from psychiatric sources.Methods A retrospective review of EEG requests in a 1-year period was performed. Analysis of referral reasons for psychiatric patients was undertaken, and outcome of patients referred from psychiatric services post-EEG was reviewed.Results One thousand four hundred and seventy EEGs were reviewed, of which 91 (6.2%) were referred from psychiatry. Neurology service referrals had detection rates of abnormal EEGs of 27%, with psychiatric referrals having the lowest abnormality detection rate of 17.6% (p < 0.1). In psychiatric-referred patients the only significant predictors found of an abnormal EEG were a known history of epilepsy (p < 0.001), being on clozapine (p < 0.05), and a possible convulsive seizure (RR = 6.51). Follow-up data of 53 patients did not reveal a significant clinical impact of EEG results on patient management.Conclusions Many patients are referred for EEG from psychiatric sources despite a relatively low index of suspicion of an organic brain disorders, based on reasons for referral documented, with an unsurprising low clinical yield.
