患有痴呆症的人通常身体活动少，睡眠也有问题。这项研究的重点是日常生活活动和睡眠条件，并检查使用这些参数检测痴呆症。五个被动红外（IR）传感器安装在每个14个主题的房子。每个病人都独自生活。受试者的室内运动由被动红外传感器记录约3个月（平均78天）。根据这些记录，评估以下生活活动参数：（1）外出次数，（2）总睡眠时间，（3）睡眠中断次数，（4）睡眠节律。认知受损的受试者（简易精神状态检查[MMSE] < 24）与对照受试者（MMSE >或= 24）相比，外出次数明显较少（p = 0.001），睡眠时间倾向于更短（p = 0.054）。这些结果表明，使用被动红外传感器监测生命活动可能是一种有效的方法来检测痴呆症。
People with dementia often have low physical activity and some sleep problems. This study focused on daily life activities and sleeping conditions, and examined the use of these parameters for detecting dementia. Five passive infrared (IR) sensors were installed in each of 14 subject's houses. Each patient lived alone. The subjects' in-house movements were recorded by the passive IR sensor for approximately 3 months (average, 78 days). Based on these records, the following parameters of life activities were assessed: (1) the number of outings, (2) total sleep time, (3) number of sleep interruptions, and (4) sleep rhythm. Subjects with impaired cognition (Mini Mental State Examination [MMSE] < 24) had a significantly lesser number of outings (p = 0.001) and a tendency toward a shorter sleep time (p = 0.054) in comparison with control subjects (MMSE >or= 24). These results suggest that the monitoring of life activities by using passive infrared sensors could be an efficient method for detecting dementia.
