In 63 depressed patients, the associations between severity of depression, psychomotor retardation, assessed by the Bech-Rafaelsen Melancholia Scale, and EEG spectral analysis were examined. Slow EEG activity (theta 2/alpha 1 bands) was positively and fast activity (alpha 3/beta bands) negatively correlated with the observed retardation. Out of the four retardation subitems (motor, verbal, intellectual and emotional), motor retardation was closest correlated with slow EEG activity.
在63名抑郁症患者中，研究了通过Bech-Rafaelsen忧郁量表评估的抑郁严重程度、精神运动迟缓与脑电图频谱分析之间的关联。脑电图慢活动（θ2/α1频段）与观察到的迟缓呈正相关，快活动（α3/β频段）与观察到的迟缓呈负相关。在四个迟缓子项目（运动、言语、智力和情感）中，运动迟缓与脑电图慢活动的相关性最强。
