This study examines the frequency of life events before admission and before deterioration in 70 dementia patients, in comparison with 50 dementia controls living in the community and 50 fit elderly people matched for age and sex. We hypothesized that there would be an excess of events connoting changes in routine and the social environment. Specific scales were developed to measure these aspects of events. Our results supported the initial hypothesis, confirming that it is the social disruptiveness of change rather than the threat implied by life events that is associated with deterioration. The findings are discussed in the light of current models of the dementia process.
本研究调查了70名痴呆症患者入院前及病情恶化前生活事件的发生频率，并与50名社区痴呆症对照者以及50名年龄和性别相匹配的健康老年人进行了比较。我们假设，意味着日常生活和社会环境发生变化的事件会过多。为此开发了特定量表来衡量这些事件的这些方面。我们的结果支持了最初的假设，证实与病情恶化相关的是变化带来的社会干扰性，而非生活事件所隐含的威胁。我们根据当前的痴呆症病程模型对研究结果进行了讨论。
