Investigation of Eating Actions of People With Dementia From the Viewpoint of Self-Awareness

The key to improve the quality of life of people with dementia and caregivers is whether caregivers can understand the meanings of the puzzling words and deeds of people with dementia. Therefore, 2 of the authors observed and wrote down the puzzling words and deeds of 28 people with dementia in eating scenes, and these words and deeds were interpreted using our original model consisting of “theory of mind,” “self-evaluation,” and “self-consciousness.” The results indicated that the bases for why caregivers perceive the words and deeds of people with dementia in eating scenes as puzzling are (1) those unable to pass the task of self-evaluation cannot evaluate their own eating situations in comparison with social standards, and the food culture collapses and (2) those unable to pass the task of self-consciousness cannot perceive through their senses.
