The psychiatrist considering recommending an EEG should look for acute changes in the history or examination suggestive of an organic cause. If he or she judges that the EEG will help to clarify or confirm the diagnostic impression already formulated, it is worth considering whether adding provocative maneuvers could increase the yield. The authors cannot overemphasize the importance of using the EEG in correlation to further inform old-fashioned clinical detective work already in process, particularly when the EEG could rule out a potential organic contributor to a psychiatric phenotype. For routine screening without an elevated index of suspicion or for thoughtless "fishing expeditions," EEG results will surely disappoint.
考虑推荐进行脑电图（EEG）检查的精神科医生应在病史或检查中寻找提示器质性病因的急性变化。如果他或她判断脑电图将有助于澄清或确认已形成的诊断印象，那么值得考虑是否增加激发试验以提高阳性率。作者再三强调将脑电图与正在进行的传统临床诊断工作相结合的重要性，特别是当脑电图可以排除潜在的导致精神症状的器质性因素时。对于没有较高怀疑指数的常规筛查或盲目进行的“试探性检查”，脑电图结果肯定会令人失望。
