The use of advanced tracking technologies for the analysis of mobility in Alzheimer's disease and related cognitive diseases

BackgroundOne of the more common behavioral manifestations of dementia-related disorders is severe problems with out-of-home mobility. Various efforts have been attempted to attain a better understanding of mobility behavior, but most studies are based on institutionalized patients and the assessment usually relies on reports of caregivers and institutional staff, using observational approaches, activity monitoring, or behavioral checklists. The current manuscript describes the research protocol of a project that measures mobility in Alzheimers disease and related cognitive disorders in an innovative way, by taking advantage of advanced tracking technologies.Methods/designParticipants are 360 demented persons, mildly cognitively impaired persons, and unimpaired controls aged ≥ 65 in Israel and Germany. Data regarding space-time activities will be collected via a GPS tracking kit for a period of 4 weeks in 3 waves (one year apart) with the same participants (using a repeated measures design). Participants will be interviewed by use of a battery of instruments prior to and following GPS data collection. Further, a family member will complete a questionnaire both before and after data tracking.Statistical analyses will strive to explain differences in mobility based on a wide range of socio-structural, clinical, affect-related and environmental variables. We will also assess the impact of the use of advanced tracking technology on the quality of life of dementia patients and care givers, as well as its potential as a diagnostic tool. Systematic assessment of ethical issues involved in the use of tracking technology will be an integral component of the project.DiscussionThis project will be able to make a substantial contribution to basic as well as applied and clinical aspects in the area of mobility and cognitive impairment research. The innovative technologies applied in this study will allow for assessing a range of dimensions of out-of-home mobility, and provide better quality data.

Stigma by association and Alzheimer's disease

Although it is widely assumed that persons with Alzheimers disease (AD) are victims of stigmatization, little is known about courtesy stigma or stigma by association and AD. Phone interviews were conduced with 61 caregivers of persons with AD in order to assess four dimensions of stigma by association—interpersonal interaction, concealment, structural discrimination and access to social roles. The participants perceived a minimal amount of stigma directed towards themselves but a considerable percentage reported perceptions of stigma regarding the person with AD. Additionally, participants reported high levels of structural discrimination towards the person with AD and towards themselves. It was found that stigma by association related to AD is especially high in dimensions affecting the delivery of services and the lives of the person with AD.

Families’ and Professional Caregivers’ Views of Using Advanced Technology to Track People With Dementia

in this study we examined the ethical aspects of the use of the Global Positioning Systems (GPS) to track people with dementia. The findings are based on qualitative data gathered from focus groups of family and professional caregivers. The most important theme was the need to balance patients’ need for safety with the need to preserve their autonomy and privacy. The main potential benefit of the use of GPS was related to the peace of mind of the caregivers themselves. The findings also suggest that caregivers’ views change according to the locus of responsibility of the caregivers for the safety of people with dementia. The caregivers give preference to patients’ safety more than autonomy when they are responsible for the patients. When the patients are under the responsibility of other caregivers, they give preference to patients’ autonomy more than their safety. Overall, the variety and the depth of the views of different stakeholders toward the use of electronic tracking for people with dementia presented in this article provide a meaningful contribution to the ethical debate on this topic.

Examining the reliability and validity of the Hebrew version of the Mini Mental State Examination

The Mini Mental State Examination is used worldwide for the screening and diagnosis of dementia. The aim of the present study was to examine the reliability and validity of the Hebrew version of the Mini Mental State Examination. The Hebrew version of the Mini Mental State Examination was administered to 36 demented and 19 non-demented elderly persons. Test-retest reliability scores were calculated as exact agreement rates, and ranged from good to excellent for all the items. Strong convergent validity, as measured by the correlation between the MMSE and the CAMCOG (r=0.94), was found. Good predictive value was observed as over three-quarters of the participants were correctly classified as demented or non-demented. The Hebrew version of the MMSE was found to be a useful and valid instrument for the determination of dementia in the elderly population.

Perceptions of self-stigma and its correlates among older adults with depression: a preliminary study

BACKGROUND Depression is common in old age and is often associated with stigma. However, to date, little is known about self-stigma (internalization of stigmatic beliefs) in depressed older people despite its importance and consequences. The aim of this study was to examine self-stigma and its correlates in depressed older people. METHODS Phone interviews were conducted with 54 persons diagnosed with major depression (78% female, average age = 74) from a psychogeriatric clinic in the central area of Israel. Self-stigma was assessed using an adapted version of the Internalized Stigma of Mental Health (ISMI) scale. Symptoms of depression were assessed using the short form of the Geriatric Depression Scale (GDS). Self-esteem was measured using Rosenbergs Self Esteem Scale. Information regarding sociodemographic and psychiatric health characteristics was also collected. RESULTS Self-stigma was relatively moderate with 10% to 20% of the participants reporting self-stigma. Those who reported higher levels of self-stigma were younger than those who did not report it. Income and education were lower in persons who reported high levels of stigmatization. Persons who reported stigmatization scored higher on the GDS and reported lower self-esteem than those without stigmatization. CONCLUSIONS This study represents an effort to examine the correlates of self-stigma in depressed older people. Since self-stigma exists among older adults, further studies are required to extend this body of knowledge.

Who should make the decision on the use of GPS for people with dementia

Objectives: In recent years advanced technologies, such as Global Positioning Systems (GPS), allow for tracking of human spatial activity and provide the ability to intervene to manage that activity. The purpose of this study is to examine the issue of who should decide about the use of electronic tracking using GPS for people with dementia. Methods: Based on quantitative data collected from 296 participants comprising cognitively intact elderly, family caregivers of people with dementia, social workers, other professionals, and social work students, study participants were asked to rate nine different potential decision-makers to make this decision. Results: The results show that figures inside the family, particularly the spouse or the most involved family caregiver, were perceived more important in the decision-making process than figures outside the family, whereas the person with dementia was ranked third in the order of the figures. Since the decision to use GPS for tracking raises the ethical dilemma of personal safety versus autonomy and privacy of people with dementia, the findings seem to indicate that the reluctance of professional caregivers to assist family caregivers to make this decision is experienced as frustrating. Conclusions: The findings imply that in order to reach a balance between the wishes and interests of both people with dementia and their family caregivers, there is a need for more active involvement of the professional caregivers to facilitate the family decision-making process.

Out-of-Home Behavior and Cognitive Impairment in Older Adults Findings of the SenTra Project

This study explores differences in the out-of-home behavior of community-dwelling older adults with different cognitive impairment. Three levels of complexity of out-of-home behavior were distinguished: (a) mostly automatized walking behavior (low complexity), (b) global out-of-home mobility (medium complexity), and (c) defined units of concrete out-of-home activities, particularly cognitively demanding activities (high complexity). A sample of 257 older adults aged 59 to 91 years (M = 72.9 years, SD = 6.4 years) included 35 persons with early-stage Alzheimer’s disease (AD), 76 persons with mild cognitive impairment (MCI), and 146 cognitively healthy persons (CH). Mobility data were gathered by using a GPS tracking device as well as by questionnaire. Predicting cognitive impairment status by out-of-home behavior and a range of confounders by means of multinomial logistic regression revealed that only cognitively demanding activities showed at least a marginally significant difference between MCI and CH and were highly significant between AD and CH.

What do cognitively intact older people think about the use of electronic tracking devices for people with dementia? A preliminary analysis

BACKGROUND The issue of using advanced tracking technologies such as Global Positioning Systems (GPS) is part of a wider debate on the acceptability of assistive technology to older people with dementia. The use of GPS can enhance the personal safety of older people by alerting caregivers to potential dangers or adverse events that might threaten the individuals health and safety, but at the same time it raises ethical concerns. This study examines the attitudes of cognitively intact older people toward the use of tracking devices for people with dementia. METHODS The analysis is based on quantitative data from a convenience sample (n = 42) and qualitative data gathered from two focus groups of cognitively intact older people in Israel. RESULTS Whereas cognitively intact older people clearly differentiate between themselves and people with dementia, they support the use of tracking devices when dementia is either formally diagnosed or its signs are evident. They value the safety of people with dementia above preserving their autonomy. Although they perceive the decision to use tracking devices as an intra-family issue, they expect guidance from professional caregivers of people with dementia. The acceptability of tracking devices is dependent on their appropriate weight, size and ease of use. CONCLUSIONS Cognitively intact older people favor the idea of tracking people with dementia. To facilitate family decision-making on the use of tracking devices, structured meetings guided by professionals and including persons with dementia and their family caregivers are suggested.

Comparison of a clock drawing test in elderly schizophrenia and Alzheimer's disease patients : A preliminary study

The objective of this study was to compare between the quantitative and qualitative aspects of a clock drawing test in elderly schizophrenic and Alzheimers disease (AD) patients. Three independent raters performed a retrospective analysis of the clock drawing item from the Cambridge Cognitive Examination (CAMCOG), in long‐term open wards of a public psychiatric hospital and an outpatient psychogeriatric clinic. The study group comprised 21 elderly schizophrenic patients (‘graduates’) and 21 AD patients matched for gender and education, and cognitive impairment confirmed by a Folstein mini‐mental state examination (MMSE) score of 18–23.

Development and Validity of the Family Stigma in Alzheimer's Disease Scale (FS-ADS)

Although it is widely assumed that persons with Alzheimer disease (AD) and their family caregivers are victims of stigmatization, family stigma in the area of AD has received surprisingly limited attention. Reliable, valid, and user-friendly scales are a first step in expanding this body of knowledge. The aim of this study was to develop and examine the validity of the Family Stigma in Alzheimers disease Scale. Interviews were conducted with 185 children of persons with AD. A pool of 100 items was identified from the literature and an earlier qualitative study including 3 dimensions (caregivers’ stigma, lay persons’ stigma, and structural stigma). Exploratory factor analyses, theoretical relevance, and internal reliability analyses allowed us to reduce the pull to 62 items. Regarding construct validity, statistically significant associations were found between family stigma and caregivers’ burden and behavioral problems, in most of the scales. Although further testing is warranted, these findings indicate that the Family Stigma in Alzheimers disease Scale is a reliable and valid instrument for assessing stigma in the context of AD.
