Withering Minds: towards a unified embodied mind theory of personal identity for understanding dementia

[Paradoxical lucidity and personal identity in patients with advanced dementia: change of paradigm?]

In this article we approach the concept of paradoxical lucidity (LP) (an unexpected, spontaneous, significant and relevant episode of communication or connection) in persons with advanced dementia. The existence of LP could change the paradigm of dementia as a degenerative, chronic, progressive and irreversible disease (where neuronal death plays the leading role), towards a model where functional deficits of neuronal networks acquire importance, which raises new potentially reversible therapeutic and rehabilitative possibilities. We analyze the ethical consequences that these episodes may have with respect to the implicated persons (patients, caregivers and professionals in charge of their care) and try to answer the following question: Do persons with advanced dementia continue to maintain their personal identity despite suffering cognitive impairment so severe?. The LP indicates that this is possible. In this work we make a transversal outline of the different concepts and theories of personal identity in these patients, from different areas of knowledge (philosophy, psychology, neuroscience).

Personhood as projection: the value of multiple conceptions of personhood for understanding the dehumanisation of people living with dementia

We examine the concept of personhood in relation to people living with dementia and implications for the humanity of care, drawing on a body of ethnographic work. Much debate has searched for an adequate account of the person for these purposes. Broad contrasts can be made between accounts focusing on cognition and mental faculties, and accounts focusing on embodied and relational aspects of the person. Some have suggested the concept of the person is critical for good care; others suggest the vexed debates mean that the concept should be abandoned. We argue instead that the competing accounts illuminate the very tensions in personhood which are manifest for all of us, but especially for people living with dementia, and argue that our account has explanatory power in shedding light on how precisely dehumanisation and constraints on agency may arise for people living with dementia, and for staff, within an institutional context.

Verbal and Nonverbal Expressions of Persons Living With Dementia as Indicators of Person-Centered Caregiving

BACKGROUND AND OBJECTIVES

Improved measures capable of capturing the influence of person-centered caregiving by staff in formal care settings on people living with dementia beyond deficit-oriented outcomes such as absence or reduction of symptoms are important for measuring progress toward improvements in well-being. This exploratory ethnographic study aimed to identify verbal and nonverbal expressions evidenced by people living with dementia surrounding person-centered caregiving approaches and to consider their use in informing temporally specific observational measures.

RESEARCH DESIGN AND METHODS

This study adopted a microethnographic approach through secondary analysis of 5.3 h of audiovisual observations of people living with dementia (N = 9) in nursing home settings at mealtimes. We observed expressions surrounding person-centered caregiving approaches. A systematic review of audiovisual observations generated codes (observable indicators) of expressions that were characterized at their most discrete and unambiguous level.

RESULTS

Drawing from 82 observable verbal and nonverbal expressions by people living with dementia, 14 discrete observable indicators were identified, broadly evidencing shifts in engagement and communication. We found that people living with dementia's expressions served both responsive and initiatory communicative purposes.

DISCUSSION AND IMPLICATIONS

Efforts to expand positive outcome measurement for people living with dementia should extend beyond characterizing them as passive respondents toward active participants in their lived experiences. Identified observable indicators can inform efforts to refine and validate measures of expressions among people living with dementia. Further research can extend this inquiry into different contexts and engage input from people living with dementia and caregivers.
