Instrumental Activities of Daily Living: The Relationships to Self-rated Memory and Cognitive Performance among 75-year-old Men and Women

Cognitive Impairment and Associated Factors Among Adult Hypothyroid Patients in Referral Hospitals, Amhara Region, Ethiopia: Multicenter Cross-Sectional Study

BACKGROUND

Cognitive impairment is a common complication of hypothyroidism that affects the patient's quality of life in different aspects. In Ethiopia, though the prevalence of hypothyroidism is high the magnitude of cognitive impairment among these patients is not known. Therefore, the current study is aimed at determining the prevalence of cognitive impairment and associated factors among adult hypothyroid patients.

METHODS

An institution-based cross-sectional study was employed from February 24 to May 22, 2020, to assess the prevalence of cognitive impairment and associated factors among adult hypothyroid patients. Data was collected by a pretested interviewer-administered structured questionnaire and standardized Mini-mental state examination (SMMSE) tool. A cluster sampling technique was used. Data was entered into Epidata version 4.6 and exported into a statistical package for social science (SPSS) version 25 for further analysis. Both bivariable and multivariable logistic regression analyses were done. A 95% confidence interval and P-value <0.05 were used to declare statistical significance.

RESULTS

A total of 216 adult hypothyroid patients were included with a response rate of 98.6%. The mean age was 42.5 (± 11) years. The prevalence of cognitive impairment was 27.3% (95% CI (21.7, 33.8)) and it was significantly associated with increased age (AOR = 1.23, 95% CI (1.11, 1.34)), increased duration of illness (AOR = 1.48, 95% CI (1.14, 1.90)) and high thyroid-stimulating hormone (TSH) level (AOR = 1.3, 95% CI (1.1, 1.6)).

CONCLUSION

The prevalence of cognitive impairment among hypothyroid patients was high. Increased age, increased duration of illness and high TSH levels were significantly associated with cognitive impairment. Hence, early screening of cognitive impairment among hypothyroid patients with increased age, increased duration of illness and high TSH level should be given due emphasis to increase patients quality of life.

Focus on Leisure Repertoire in the Oldest Old: The Umeå 85+ Study

This study elucidates the oldest olds’ leisure repertoire and how this repertoire varies due to gender, where they live, and cognitive status. A validated 20-item leisure interest checklist with four subscales was used to measure leisure participation and investigate the leisure repertoire among participants. The oldest old were most likely to be interested in, perform, be motivated for, and perceive well-being from social activities, cultural activities, and TV/video/movies. The respondents were least likely to be interested in, perform, be motivated for, and perceive well-being from equipment sports and ball games. Some gender, geographic differences, and differences in cognitive status were found. The oldest old were more likely to endorse the same activities across all subscales of the checklist, but the linear magnitude varied across sub-scales. The relationships between performance and the other subscales suggested that a sense of engagement or participation is related to actual performance.

Cognitive impairment and its consequences in everyday life: experiences of people with mild cognitive impairment or mild dementia and their relatives

BACKGROUND

The aim of this study was to explore experiences of cognitive impairment, its consequences in everyday life and need for support in people with mild cognitive impairment (MCI) or mild dementia and their relatives.

METHODS

A qualitative approach with an explorative design with interviews was chosen. The participants included five people with MCI and eight people with mild dementia and their relatives. All participants were recruited at a geriatric memory clinic in Sweden. The Grounded Theory method was used.

RESULTS

The following categories emerged: noticing cognitive changes; changed activity patterns; coping strategies; uncertainty about own ability and environmental reactions; support in everyday life; support from the healthcare system; consequences in everyday life for relatives; and support for relatives. The main findings were that people with MCI and dementia experienced cognitive changes that could be burdensome and changed activity patterns. Most of them, however, considered themselves capable of coping on their own. The relatives noticed cognitive changes and activity disruptions to a greater extent and tried to be supportive in everyday life. Degree of awareness varied and lack of awareness could lead to many problems in everyday life.

CONCLUSIONS

Perceived cognitive impairment and its consequences in everyday life were individual and differed among people with MCI or dementia and their relatives. Thus, healthcare professionals must listen to both people with cognitive impairment and their relatives for optimal individual care planning. Support such as education groups and day care could be more tailored towards the early stages of dementia.

Disability in instrumental activities of daily living in elderly patients with mild cognitive impairment and Alzheimer's disease

BACKGROUND/AIMS

The aim is to examine disability in instrumental activities of daily living (IADL) in elderly persons with mild cognitive impairment (MCI) and Alzheimer's disease (AD), further to identify items of IADL which separate the two conditions and to explore potential gender differences.

METHODS

A cross-sectional study of 729 patients aged ≥65 years recruited from outpatient memory clinics. Multiple logistic regression analysis was used in the main analysis to explore the association between IADL and diagnosis.

RESULTS AND CONCLUSIONS

We found an association between IADL and diagnosis, and a difference in the proportion of disability in IADL in patients with MCI and AD, i.e. 66 and 88%, respectively. Six of the 8 items revealed differences in the proportions of patients with IADL disability among MCI and AD. No substantial gender differences were found, except for laundry.

Fatigue in older adults: an early indicator of the aging process?

The aim of this paper is to give an overview of research on fatigue in older adults, with a focus on fatigue as an early indicator of the aging process. Fatigue is a strong predictor of functional limitations, disability, mortality, and other adverse outcomes in young-old and old-old populations, between men and women, and in different geographic localities. Several biological, physiological and social explanations are proposed: fatigue may be seen not only as a self-reported indicator of frailty, defined as a physiologic state of increased vulnerability to stressors, which results from decreased physiologic reserves and even dysregulation of multiple physiologic systems, but also this state may be accelerated because of the cumulative impact of social, mental and biological factors throughout life.

Cognitive Impairment after Stroke – Impact on Activities of Daily Living and Costs of Care for Elderly People

BACKGROUND AND PURPOSE

The economic burden of stroke is substantial and is likely to increase with an increasing number of elderly individuals in the population. There is thus a need for information on the use of health care resources and costs among these elderly stroke patients. We examined the impact of the cognitive impairments on the ability to perform activities of daily living (ADL) and utilization and costs of health care in a cohort of elderly stroke patients.

METHODS

One hundred and forty-nine patients aged >/=70 years with acute stroke were included. The patients were assessed regarding their ability to carry out ADL and health resource utilization and cost during the first year after stroke. Cognitive impairments were assessed 18 months after the index stroke.

RESULTS

Stroke severity in acute stroke and cognitive impairment at 18 months after stroke onset was associated with impairment in ADL and increased costs for utilisation of care during the first year. Patients with cognitive impairment were more dependent on personal assistance in ADL. Costs per patient during the study were three times higher for patients with cognitive impairment. Hospital care, institutional living and different kinds of support from society accounted for the highest costs.

CONCLUSIONS

Costs of care utilisation during the first year after stroke were associated with cognitive impairments, stroke severity and dependence in ADL. The results should be interpreted cautiously as the assessment of cognitive function was made 18 months after stroke onset and costs were estimated for the first year after stroke.

The impact of structural and functional characteristics of social relations as determinants of functional decline

OBJECTIVES

This study examines whether aspects of social relations at baseline are related to functional decline at 5-year follow-up among nondisabled old men and women.

METHODS

The investigation is based on baseline and follow-up data on 651 nondisabled 75-year-old persons in Jyväskylä (Finland) and Glostrup (Denmark). The analyses are performed separately for men and women. Possible selection problems were considered by using three outcome measures: first, functional decline among the survivors (n = 425); second, functional decline, including death, assuming that death is part of a general decline pattern (n = 565); and third, mortality (n = 651). Social relations were measured at baseline by several items focusing on the structure and function of the social network.

RESULTS

In men, no weekly telephone contact was related to functional decline and mortality. Among women, less than weekly telephone contact, no membership in a retirement club, and not sewing for others were significantly related to functional decline and mortality. The associations were stronger when the dead were included in the outcome measure.

DISCUSSION

The results point to the importance of social relations in the prevention of functional decline in older adults.

Attentional abilities and functional outcomes following stroke

Although stroke affects cognitive functioning as well as motor functioning, research on cognitive consequences has lagged behind that focused on motor function. The evidence that is accruing suggests that cognitive function is importantly related to successful rehabilitation. The present study examined two aspects of attentional functioning (divided attention and switching attention) in older adult stroke survivors and healthy older adults. In addition, the authors investigated the relation between attention and functional outcomes following stroke. Results revealed stroke-related deficits in both of the types of attention as well as significant associations between attentional functioning and both physical and social outcome measures. Poorer attentional performance was associated with a more negative impact of stroke on daily functioning. These findings suggest an important role for attention in post-stroke function and provide information that can contribute to improving outcomes following stroke.

Cognitive function and functional ability. A cross-sectional and longitudinal study at ages 85 and 95 in a non-demented population

We studied the relationship between cognitive function and ability in daily life activities (ADL) at ages 85 (N=332) and 95 (N=63) cross-sectionally and longitudinally in representative populations of non-demented persons, in order to focus on manifestations related to healthy aging. Among the 85-year olds, 31% were independent, 42% were dependent on personal assistance in instrumental ADL (IADL) and 27% in personal ADL (PADL); the corresponding figures for the 95-year olds were 8, 40 and 52%, respectively. Regarding the relationship between cognitive function and ADL, the analysis could only be performed in the cross-sectional data. At age 85 a significant trend was found regarding nearly all cognitive tests for both men and women, indicating that subjects who were ADL-independent had better results than those dependent in IADL, and both IADL and PADL. At age 95, no such trend was found in males, but in females the trend was significant, and those dependent in ADL had poorer results in the separate cognitive tests. By combining the different cognitive tests into a compiled cognitive index, it was seen that the most ADL-dependent persons were more cognitively impaired both at ages 85 and 95, compared to persons who were ADL-independent. Not only cognitive functioning (OR 3.3), but also mobility (OR 4.9) and tiredness (OR 3.3) were independent predictors for ADL-dependence among the 85-year olds.
