Due to the phenomenon of ageing population, cognitive impairment has become more prevalent, and any marker able to improve its detection becomes of significant importance. With that objective in mind, a prospective observational study was performed in a medical consultation related to cognitive impairment. 150 subjects (58% women) were included with an average age of 76 years (SD 8.6). The Head Turn sign was positive for 32 subjects with a sensitivity of 41.7% for dementia, a specificity of 93.7% and a negative predictive value of 64.4%. This study shows the semiologic value of a simple clinical sign, easy to spot in the daily practice and most helpful to alert physicians about a likely dementia diagnosis.
由于人口老龄化现象，认知障碍变得更加普遍，任何能够改善其检测的标志物都变得至关重要。出于这一目的，在一次与认知障碍相关的医疗咨询中进行了一项前瞻性观察研究。纳入了150名受试者（58%为女性），平均年龄为76岁（标准差8.6）。32名受试者的头部转动征呈阳性，对痴呆的敏感性为41.7%，特异性为93.7%，阴性预测值为64.4%。这项研究显示了一个简单临床体征的症状学价值，该体征在日常实践中易于发现，对提醒医生注意可能的痴呆诊断非常有帮助。
