Caregivers' roles in preventing patients with severe Alzheimer's disease from becoming distracted during mealtimes: two case reports.

[Purpose] The purpose of this study was to identify the roles of caregivers in preventing patients with severe Alzheimer's disease with loss of language skills from becoming distracted while eating their meals. [Participants and Methods] The study was conducted on two residents of a nursing home with severe Alzheimer's disease who had lost their language skills. In this study, by comparing the scenes in which the two participants were distracted and not distracted from eating, we analyzed the factors associated with patients with severe Alzheimer's disease who had lost their language skills becoming distracted and factors that prevented them from becoming distracted from eating at mealtimes and considered the roles of caregivers. [Results] The participants became distracted from eating where they were in a lively environment. On the other hand, they were not distracted when they were made to sit and eat in quiet environments. [Conclusion] Patients with severe Alzheimer's disease who have lost their language skills cannot filter out a range of other information around them and focus on the information necessary to oneself. The role of caregivers is to serve as filters for patients with severe Alzheimer's disease who have lost their language skills and whose selective attention abilities have become impaired.
