Clock-watching activity in patients with dementia has not been documented in detail.
A male patient having semantic dementia was monitored at a dementia care unit in a general hospital in Japan. We used an integrated circuit monitoring system to record the distance and location of ambulation and the total number of movements that occurred outside the patient's room.
The patient was reported to clock watch a couple of years prior to monitoring. In 2011, when monitoring started, he regularly came out of his room saying, "8 o'clock" about 40 minutes into every hour. It seemed as if he could only recognize the minute hand. The median number of sensor detections increased by 4-fold at this clock-watching phase. Behavior consistent with his clock-watching patterns was also detected during the night. In 2012, clock-watching activity disappeared.
This study documented the progression of clock-watching and subsequent disappearance with worsening cognitive function.
痴呆患者看钟活动尚未得到详细记录。
在日本一家综合医院的痴呆护理病房对一名患有语义性痴呆的男性患者进行监测。我们使用集成电路监测系统记录其行走的距离和位置以及在病房外发生的总活动次数。
据报告，该患者在监测前几年就有看钟行为。2011年监测开始时，他每小时大约40分钟就会经常走出房间说“8点”。似乎他只能认出分针。在这个看钟阶段，传感器检测的中位数增加了4倍。夜间也检测到了与他看钟模式一致的行为。2012年，看钟活动消失。
本研究记录了随着认知功能恶化看钟行为的进展及随后的消失情况。
