A group of 55 patients were studied who showed in their EEGs prolonged episodes of delta activity, in response to either auditory or tactile stimuli or both. This unusual pattern occurred with states ranging from drowsiness to deep coma but never in alert patients. It was found in a variety of conditions, most commonly following head injury. The EEG phenomenon disappeared within 5 weeks and over half of the patients had a favourable outcome.
对一组55名患者进行了研究，这些患者的脑电图显示，对听觉或触觉刺激或两者都有反应时，会出现长时间的δ波活动。这种不寻常的模式出现在从嗜睡到深度昏迷的各种状态中，但从不出现在清醒的患者中。在多种情况下都发现了这种情况，最常见于头部受伤后。脑电图现象在5周内消失，超过一半的患者预后良好。
