Diffuse slowing constitutes 40% of all electroencephalogram (EEG) abnormalities in psychiatric patients. Correlations have been demonstrated between the degree of slowing of the EEG and impairment of functions such as awareness, attention, memory, and comprehension. We conducted the current study in order to determine whether diffuse EEG slowing in hospitalized psychiatric patients correlated with hospitalization indices. Twenty-five patients with diffusely slow EEGs were selected for the study, and 25 patients with normal EEGs were matched to these subjects. Medical records were reviewed for each patient's diagnosis, length of stay, number of medications, and the dosages. Length of stay was significantly longer in the slow EEG group. The number of psychotropic medications used and the dosages of antipsychotic medications were also significantly higher in the slow EEG group. We concluded that the longer length of stay and the increased number of medications and dosages in the slow EEG group may be a reflection of increased illness severity.
弥漫性慢波构成了精神科患者所有脑电图（EEG）异常的40%。脑电图的慢波程度与意识、注意力、记忆和理解等功能损害之间已被证实存在相关性。我们进行了本研究，以确定住院精神科患者的弥漫性脑电图慢波是否与住院指标相关。选择了25名脑电图弥漫性减慢的患者进行研究，并将25名脑电图正常的患者与这些受试者进行匹配。查阅了每位患者的病历，以了解其诊断、住院时间、用药数量和剂量。脑电图慢波组的住院时间明显更长。脑电图慢波组使用的精神药物数量和抗精神病药物剂量也明显更高。我们得出结论，脑电图慢波组较长的住院时间以及增加的药物数量和剂量可能反映了疾病严重程度的增加。
