Understanding the self of people with dementia : Psychological and philosophical considerations.

BACKGROUND

The ability to create and maintain an ongoing life narrative is a key characteristic of what makes us human; however, people with dementia lose this ability in the course of the disease. If the notion of having a self is intimately linked with being able to create and maintain a life narrative and if people with dementia tend to lose this ability, what kind of self do people with dementia still possess?

OBJECTIVE AND METHODS

Recent theories developed in psychology and philosophy suggest that at least two notions of the self have to be distinguished: the experiencing self and the remembering self. This distinction is applied to people with dementia.

RESULTS

While the remembering self is impaired in people with dementia, their experiencing self remains relatively intact. Critically, the experiencing self is a self with inner depth, mirroring the life history of the individual. Thus, the self of people with dementia is not unextended in time. Although people with dementia may have lost the ability to tell a story about their life, they are still able to express this story in their behavior.

CONCLUSION

Understanding the structure of the self of people with dementia can help guide interactions as well as the designing of appropriate interventions and environments. Moreover, realizing the inner depth of the self of people with dementia may help acknowledge their dignity and personhood.
