Objective, rapid evaluation of cognitive function is critical for identifying situational impairment due to sleep deprivation. The present study used brain vital sign monitoring to evaluate acute changes in cognitive function for healthy adults. Thirty (30) participants were scanned using portable electroencephalography before and after either a night of regular sleep or a night of total sleep deprivation. Brain vital signs were extracted from three established event-related potential components: (1) the N100 (Auditory sensation); (2) the P300 (Basic attention); and (3) the N400 (Cognitive processing) for all time points. As predicted, the P300 amplitude was significantly reduced in the sleep deprivation group. The findings indicate that it is possible to detect situational cognitive impairment due to sleep deprivation using objective, rapid brain vital sign monitoring.

客观、快速地评估认知功能对于识别睡眠不足造成的情境障碍至关重要。本研究使用大脑生命体征监测来评估健康成年人认知功能的急性变化。三十 (30) 名参与者在一晚正常睡眠或一晚完全睡眠剥夺之前和之后使用便携式脑电图进行扫描。大脑生命体征是从三个已确定的事件相关电位成分中提取的：（1）N100（听觉）； (2) P300（基本注意）； (3) 所有时间点的 N400（认知处理）。正如预测的那样，睡眠剥夺组的 P300 振幅显着降低。研究结果表明，通过客观、快速的大脑生命体征监测，可以检测由于睡眠不足而导致的情境性认知障碍。
