Beyond Diagnosis: Exploring Residual Autonomy in Dementia Through a Systematic Review

Background and Objectives: The connection between cognitive decline and autonomy represents a complex and multifactorial area of research. Cognitive decline manifests as a progressive impairment of higher mental functions and is typical of neurodegenerative conditions such as dementia. Autonomy, on the other hand, is defined as an individual's ability to independently manage activities of daily living and make informed decisions. The objective of this study was to investigate whether certain daily living skills can persist despite the advancement of dementia, and what factors contribute to their preservation in maintaining autonomy. Materials and Methods: A literature review was conducted using the databases PubMed, Web of Science, Scopus, Cochrane Library, Embase, and PsycInfo. Out of an initial pool of 12,113 studies, only 19 met the inclusion criteria and were selected for analysis. Results: The findings indicate that, in non-institutionalized settings, some daily living abilities may remain preserved despite cognitive deterioration. In contrast, within institutionalized environments, a significant correlation emerged between cognitive decline and the progressive loss of personal autonomy. Conclusions: This study highlights the importance of assessing residual abilities in individuals with dementia. Recognizing and supporting these remaining skills can play a crucial role in enhancing quality of life, delaying institutionalization, and promoting autonomy even in the presence of advanced cognitive decline.
