During posttraumatic amnesia (PTA), confusion, attention deficits, impaired memory, disorientation, and inability to process external stimuli often preclude accurate assessment of subtle neurologic changes. The Orientation Group Monitoring System (OGMS) has proven to be a simple, useful strategy for assessing cognitive status. Retrospective analysis of weekly aggregate OGMS scores indicated that a decline in performance of 0.23 or greater is clinically significant. Over a one-year period, 27 patients demonstrated significant decrements in OGMS performance, and in 93% of these instances, the decrease was attributable to a medical problem. Adverse effects of medication was the most common etiology of decreased performance (n = 13). Overwhelmingly, the decline in the OGMS score was the first indication of impaired cognition. This monitoring device is therefore useful as an indicator during PTA of declining cognitive function, warranting further medical evaluation.
在创伤后遗忘症（PTA）期间，意识混乱、注意力缺陷、记忆力受损、定向障碍以及无法处理外部刺激常常妨碍对细微神经学变化进行准确评估。定向组监测系统（OGMS）已被证明是一种评估认知状态的简单且有用的策略。对每周OGMS总分的回顾性分析表明，表现下降0.23或更多具有临床意义。在一年的时间里，27名患者的OGMS表现出现显著下降，在这些病例中，93%的下降归因于医疗问题。药物不良反应是表现下降最常见的病因（n = 13）。绝大多数情况下，OGMS评分下降是认知受损的首个迹象。因此，这种监测设备在PTA期间作为认知功能下降的指标很有用，需要进一步的医学评估。
