Abstract [en]

This study investigates how cognition influences activities of daily living and health-related quality of life in 85-year-olds in Sweden (n = 373). Data collection included a postal questionnaire comprising demographics and health-related quality of life measured by the EQ-5D. The ability to perform personal activities of daily living (PADL) was assessed during a home visit that included administering the Mini Mental State Examination (MMSE). Cognitive impairment was shown in 108 individuals (29%). The majority were independent with respect to PADL. A larger number of participants with cognitive impairment reported that they needed assistance in instrumental activities of daily living (IADL) compared to the group without cognitive impairment. Impaired cognition was significantly related to problems with IADL. Significant but low correlations were found between cognition and health-related quality of life – higher ratings on perceived quality of life correlated with higher results on the MMSE.

Abstract [en]

The overall aim was to improve knowledge of the consequences of cognitive dysfunction in everyday life and of instruments to make these assessments. The thesis contains four studies each of different design using different populations.

In study I, the relationship between cognitive function, ability to perform activities of daily living and perceived health-related quality of life were investigated in a population of 85-year-old individuals in the community of Linköping (n = 373). The study was part of the Elderly in Linköping Screening Assessment 85 (ELSA 85). Even mild cognitive dysfunction correlated with impaired ability to perform activities of daily living and lower health-related quality of life.

In study II, the diagnostic accuracy and clinical utility of Cognistat, a cognitive screening instrument, were evaluated for identifying individuals with cognitive impairment in a primary care population. Cognistat has relatively good diagnostic accuracy with a sensitivity of 0.85, a specificity of 0.79 and a Clinical Utility Index (CUI) of 0.72. The corresponding values were 0.59, 0.91 and 0.53 for the Mini Mental State Examination (MMSE), and 0.26, 0.88 and 0.20 for the Clock Drawing Test (CDT).

In study III, the aim was to develop an instrument measuring self-perceived or caregiver reported ability to perform everyday life activities in persons with suspected cognitive impairment or dementia and to perform psychometric testing of this instrument, named the Cognitive Impairment in Daily Life (CID). The CID was found to have good content validity.

In study IV, experiences of cognitive impairment, its consequences in everyday life and the need for support in persons with mild cognitive impairment (MCI) or mild dementia and their relatives were explored. Interviews were performed with five people with MCI, eight people with mild dementia and their relatives (n = 13). The main finding was that persons with MCI and dementia experienced cognitive changes that could be burdensome and result in changed activity patterns.

In conclusion, the findings support earlier research and show that cognitive dysfunction even at mild stages has an impact on everyday life and reduces perceived quality of life. To improve interventions for persons with cognitive impairment, it is important to assess not only cognitive function but also its consequences in everyday life activities.
