The Relationship Between Cognition and Daily Activities in Cases of Mild Alzheimer's Disease

Is a structured work task application for the assessment of work performance in a constructed environment, useful for patients with attention deficits?

BACKGROUND

The purpose of our study was to develop a Structured Work Task application for the Assessment of Work Performance for patients with attention deficits.

MATERIAL AND METHODS

We developed a computer-based registration task titled the Attention-demanding Registration Task. It had a structured administrative procedure with additional scoring regarding time and accuracy, also linked to the original scoring of the Assessment of Work Performance. We evaluated the Attention-demanding Registration Task for content validity. Furthermore, we investigated it concerning sensitivity and specificity in patients with attention deficits due to acquired brain injury (n = 65) against a comparison group of healthy people (n = 47).

RESULTS

Our investigation on content validity using the Assessment of Work Characteristics confirmed that the Attention-demanding Registration Task sets high demands on process skills, especially on energy, temporal organization, and adaptation. The Attention-demanding Registration Task showed high sensitivity and specificity in differing between patients with attention deficits and a healthy working group; nine out of ten participants were placed in the correct group.

CONCLUSIONS

To assess work performance, the use of a Structured Work Task application, the Attention-demanding Registration Task, linked with the Assessment of Work Performance, proved to be sensitive to attention deficits.Implications for rehabilitationA Structured Work Task application for the Assessment of Work Performance was developed for use in people with attention deficits and showing a high degree of sensitivity and specificity.Linking performance time and accuracy to the Assessment of Work Performance scoring and providing a guide for linking task performance to the Assessment of Work Performance skills in addition to the usual observations performed, may increase scoring accuracy.Reference data for a comparison group of healthy subjects are provided.The use of the Attention demanding Registration Task, while using the Assessment of Work Performance within clinical practice ensures a more accurate description of process skills in performance.

Predictors of care dependency in nursing home residents with moderate to severe dementia: A cross-sectional study

BACKGROUND

Nursing home residents with dementia show a rapid decline in their ability to perform activities of daily living. This decline is linked to a greater care dependency, which is associated with a reduced quality of life. Care dependency is influenced by multiple predictors, yet current research often focuses on the contribution of a single or a small number of predictors of care dependency.

OBJECTIVES

To examine the contribution of multiple predictors in predicting care dependency.

DESIGN

The present study analyzed baseline data from a 6-month double-parallel randomized controlled trial which examined the effect of three physical activity interventions on multiple outcomes.

SETTING

This study was conducted in eleven nursing homes in Bergen op Zoom, the Netherlands.

PARTICIPANTS

In total, 85 nursing home residents with moderate to severe dementia were included in the study, of which 75 were included for analysis.

METHODS

Predictors considered were cognitive, physical, neuropsychiatric, demographic, and disease related factors. The outcome measure care dependency was assessed with the Care Dependency Scale and the Erlangen Test of Activities of Daily Living. Linear multilevel regression analyses were used to identify the most important predictors of care dependency.

RESULTS

Apathy, physical endurance, number of comorbidities, and global cognition were significant predictors of care dependency. The model explained 66% of the variance in care dependency. Global cognition was a significant predictor of ability to perform activities of daily living and explained 60% percent of its variance.

CONCLUSION

The present study shows that multiple predictors (i.e., apathy, cognitive and physical abilities, and disease-related factors) contribute to predicting care dependency. Future research could focus on the effectiveness of multifactorial interventions to maintain the highest possible level of independence in nursing home residents with dementia.

Effects of physically active video gaming on cognition and activities of daily living in childhood brain tumor survivors: a randomized pilot study

Background

Physical activity can enhance cognitive functions in both animals and humans. We hypothesized that physically active video gaming could: i) improve cognitive functions and ii) improve the execution of activities of daily living among survivors of childhood brain tumors.

Methods

Children 7 to 17 years old who completed treatment, including radiotherapy, for a brain tumor 1 to 5 years earlier were randomized to either intervention or waiting list. After 10 to 12 weeks the groups crossed over. The intervention consisted of active video gaming, using a motion-controlled video console (Nintendo Wii), for a minimum of 30 minutes a day, 5 days a week and weekly Internet-based coaching sessions. Evaluations before and after each period included tests of the execution of activities of daily living, using the Assessment of Motor and Process Skills (AMPS) and cognitive tests. Test scores before and after the intervention were compared. A parallel group comparison was performed as a sensitivity analysis.

Results

All 13 children enrolled completed the program. Compared to baseline, the motor (P= .012) and process (P=.002) parts of AMPS improved significantly after active video gaming. In the parallel group analysis the improvement in the process part of AMPS remained statistically significant (P= .029), but not the change in AMPS motor score (P= .059). No significant change was found in cognitive tests although there were trends for improvement in sustained attention (P = .090) and selective attention (P = .078).

Conclusion

In this pilot study, active video gaming used as a home-based intervention for childhood brain tumor survivors improved motor and process skills in activities of daily living.

Self-management for people with early dementia

This article describes the concept of self-management and how it is being promoted. This is followed by a consideration of why dementia has been largely set aside. Illustrations of how people with early dementia might be enabled to participate are given and the requirements that will help to make this a reality are postulated. These include early disclosure of the diagnosis, support with the consequences of disclosure, a focus upon the needs of the person with dementia, identification of specific interventions that might facilitate self-management, meeting needs for professional education and support and a whole systems approach towards treatment and care. The results of a scoping review of the evidence is given, with an extra factor of meeting needs for lay and patient education being identified in addition to those elements originally postulated. The implications of policy neglect combined with a patchy evidence base and unrecognized service innovations are discussed.

Relationships between Cognitive Abilities and the Process Scale and Skills of the Assessment of Motor and Process Skills (AMPS) in Patients with Stroke

The purpose of this study was: 1) to determine the strength of the relationships between cognitive components at the body function/impairment level to the assessment of motor and process skills (AMPS) at the occupational performance/activities level in persons following stroke; and 2) to examine which cognitive components best explain the variance of the AMPS score. Stroke is a major cause of disability in older age that can result in motor and/or cognitive impairments leading to functional disability. The assessment of AMPS is an activity of daily living (ADL) and instrument activity of daily living (IADL) evaluation that measures two aspects enabling occupational performance and motor and process skills. Subjects included 30 hospitalized patients 4 to 5 weeks following stroke. Among them were 17 men and 13 women with a mean age of 71.33 (SD = 8.39) who had been independent in ADL prior to the event. Instruments included the AMPS IADL tasks, Thinking Operations from the LOTCA, Contextual Memory Test, Rey Complex Figure-copy, Star cancellation from the BIT, and COGNISTAT. The study supports the existence of moderate relationships between cognitive components and the AMPS' process scale and skills, and the results add information about relationships between cognitive impairments and occupational performance that can help in treatment planning.

Caregivers' Self-Initiated Support toward Their Partners with Dementia When Performing an Everyday Occupation Together at Home

The aim of this study was to identify the support caregivers provide by their own initiative when performing an everyday occupation together with their partner who has dementia. This is to identify what type of self-initiated caregiver support enhances or limits the performance of the person with dementia. Thirty cohabitating couples participated. One of the spouses in each couple was the primary caregiver for a partner with mild to moderate dementia. Observational data were collected in the participants' homes, where each couple was asked to prepare afternoon tea together. The performances were documented by video and supplementary field notes. Data were analyzed using a qualitative comparative approach. The results of the analyses identified two major themes related to support the caregivers provided: provision of a supportive working climate and provision of practical support. A third theme was related to negative aspects of caregiver support. The results of this study have implications for how occupational therapists and caregivers in dementia care can support and guide primary caregivers in their homes.

Using the Assessment of Motor and Process Skills as Part of the Diagnostic Process in An Inner-City Learning Disability Service

Learning disability is characterized by significant impairment of both intellectual function and social and adaptive function, with onset before adulthood, and yet social and adaptive function is often omitted from assessment processes.

This practice analysis explores the feasibility of administering the Assessment of Motor and Process Skills to assess adaptive function (alongside the assessment of intellectual function) as part of the diagnostic process for people with a learning disability. After a 2-year period, scores for the two assessments were correlated and a low level of correlation was found.

Findings suggested that the Assessment of Motor and Process Skills should continue to be used as part of the diagnostic process alongside assessments of intellectual function, because assessment of intellectual function alone does not predict adaptive function and cannot be relied on for diagnosis of learning disability; doing so would ensure that practice was evidence based.

Cognition, daily living, and health-related quality of life in 85-year-olds in Sweden

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.

Occupational performance and awareness of disability in mild cognitive impairment or dementia

Limited awareness of disabilities is common in mild cognitive impairment and dementia. In order to get a broader base in planning interventions, it is important to consider a person's awareness of his/her disability encountered in performance. The aim of this study was to examine the relationship between occupational performance and awareness of disability in older adults with mild cognitive impairment or dementia. Thirty-five older adults were evaluated with the AMPS (Assessment of Motor and Process Skills) and with the AAD (Assessment of Awareness of Disability). Many-faceted Rasch models generated individual measures of ADL performance and awareness of disability. Non-parametric correlation statistics were used to analyse the relationships. The findings showed that there was an overall positive relationship between occupational performance and awareness of disability. However, individual variations in the sample implied that limitations in performance were not equivalent to a limited awareness of disability. In conclusion, awareness of disability should be individually evaluated when planning interventions together with clients and their families.

The international classification of functioning, disability and health and its application to cognitive disorders

PURPOSE

This paper describes the conceptual foundation and systematic framework of the International Classification of Functioning, Disability, and Health (ICF) as a mechanism for understanding the course and consequences of various health related states. The specific application of the ICF with persons with cognitive dysfunction is also presented.

METHOD

A comprehensive literature review related to the conceptualization of the ICF, its classification scheme and coding process is presented. Information on cognitive disorders including prevalence, functional manifestations and the assessment of a person's cognitive functioning and the applicability of the ICF's holistic classification and coding of cognitive dysfunction within the components of body structure and function, activity and participation, and environmental attributes is also reviewed.

CONCLUSION

The ICF has the potential to classify and interpret cognitive deficits on a global level and thereby reflects upon the overall health and functioning of the individual in major life activities. The coding system systematically organizes measures related to the person's cognitive status and the resulting functional outcomes. The ICF focuses on individuals' performance of activities in all aspects of life and validates the independence and well-being of persons with disabilities making it an important instrument to be used by rehabilitation professionals.
