Eye movement, cognition of group home physical environment, and risk of falling in elderly persons with dementia of Alzheimer's type

本研究的目的是同时测量阿尔茨海默型痴呆老年人日常生活中无限制条件下的眼动和行走，并验证他们的运动功能水平和对群体家庭物理环境或受试者生活环境的认知对跌倒和持续可能骨折的风险的影响程度。研究对象为102名社区老年痴呆症患者。从跌倒风险中涉及的个体因素和环境因素的角度进行调查。通过使用多元逻辑回归模型，发现过去的福尔斯与存在/不存在无症状性梗死、脑室周围白色病变、受试者意识到沿着道路行走的障碍物所花费的额外时间、注意到障碍物的时间较晚以及行走时的不稳定性有显著关系。其次，对20名生活在3个不同物理环境的集体之家的阿尔茨海默型轻度痴呆患者进行了随访调查。结果表明，在安全意识团体家庭中，连续行走和变换不同姿势时的移动都很稳定。此外，在布局良好的家庭与有利的环境刺激，视觉注意力转移方面的空间是可预测的，往往是顺利执行。根据上述结果，建议在集体之家环境中安排一个可识别的、安全的和具有良好生活质量的环境对老年痴呆症患者的护理是非常重要的。

The aim of the present study is to measure simultaneously both eye movement and walking in the unrestricted condition in the daily life of elderly persons with dementia of Alzheimer's type, and to verify the degree to which their level of motor function and cognition of the group home physical environment or the subjects' living environment Influence the risk of falling and sustaining a possible fracture. The subjects of the study were 102 elderly persons with dementia of Alzheimer's type living in the community. The investigation was conducted from the standpoint of Individual factors Involved In the risk of falling and environmental factors. From using multiple logistical regression models, past falls were found to have a significant relation with the present/absent of silent infarctions, periventricular white matter lesions, the extra time the subject took to be aware of obstacles to walking along the way, lateness in taking note of them, and instability when walking. Next, a follow-up survey was conducted on 20 subjects with mild dementia of Alzheimer's type liying in 3 group homes, each with a different physical environment. The results showed that in safety-minded group homes continuous walking and moving when changing to different posture were very stable. Also, in well-laid out group homes with favorable environment stimuli, visual attention shifts with regard to space were predictable and tended to be performed smoothly. On the basis of the above mentioned results, It was suggested that an environment arranged so that things will be recognizable, safe and with good quality of life Is very important for the care of the elderly with dementia of Alzheimer's type in a group home setting.
