Thirty-five patients were studied by EEG with recordings taken the day before, two weeks after, and six months after psychosurgery. Most showed a characteristic frontal slow activity of varying degrees after operation with varying enhancement of background activity. The amount and spread of the frontal slow waves two weeks after operation showed a significant positive correlation with the clinical outcome one year later, which suggests a relatively objective and very early indication of the subsequent clinical response to psychosurgery.
对35例患者在精神外科手术前一天、术后两周和术后六个月进行了脑电图(EEG)研究。大多数患者术后出现了不同程度的特征性额叶慢波活动,背景活动也有不同程度的增强。术后两周额叶慢波的数量和扩散与一年后的临床结果呈显著正相关,这表明它是对精神外科手术后续临床反应的一个相对客观且非常早期的指标。
