Evaluation of the perceived health of caregivers of patients in mild-to-moderate stage Alzheimer's disease

Smart home automation technology to support caring of individuals with Alzheimer's disease and related dementia: an early intervention framework

PURPOSE

Home automation technology comprising of Internet of Things and Smart gadgets is a rapidly growing industry that is projected to have a major scope for ageing-in-place and caregiving. This study examined the feasibility and cost-benefits of a personalized home automation intervention for care of individuals with Alzheimer's disease and related dementia (ADRD) with emphasis on their safety and independence, and reduction of care burden.

METHODS

A mixed method intervention study was conducted with five dyads each comprising of a caregiver and care recipient with ADRD. Each dyad received personalized home automation intervention with individualized goals centred on home safety, activity engagement, and caregiver-recipient connectivity. The goals were created and monitored using goal attainment scaling (GAS). The dyads were followed up after three months with a home visit and interview. Goal attainment scoring and thematic analysis of the interviews were conducted to examine the findings from the study.

RESULTS

All dyads indicated positive goal attainment between pre and post intervention. Goals that were met were complimented by the categories of peace of mind, self-efficacy, and care recipient engagement, while unmet goals as well as complexities with the technology were elucidated under challenges. Overarching and conceptually linked themes from the study were unfamiliarity, value, and timing.

CONCLUSION

Home automation technology has the potential to be adapted to promote independence and safety of individuals with ADRD while relieving care burden. Nonetheless, we propose an early intervention framework to overcome identified challenges and optimize the technology's usability and sustainability.IMPLICATIONS FOR REHABILITATIONHome automation involving Internet of Things and Smart gadgets has gained rapid popularity owing to the comfort and connectivity they provide to mainstream consumers.The technology has an emerging significance to ageing-in-place and care of individuals with Alzheimer's Disease and Related Dementia (ADRD) as it can be adapted and implemented to enhance home safety and activity engagement of the care recipients while also strengthening their connectivity with the caregivers.Unfamiliarity with the technology compounded by the progression of ADRD can, however, be detrimental to its adoption.Individualized focus and early integration of the technology for caregiver-care recipient dyads can mitigate these challenges and optimize its usability and long-term value in relation to ageing-in-place and caregiver wellbeing.

Short-Term Sleep Fragmentation Dysregulates Autophagy in a Brain Region-Specific Manner

In this study, we investigated autophagy, glial activation status, and corticotropin releasing factor (CRF) signaling in the brains of mice after 5 days of sleep fragmentation (SF). Three different brain regions including the striatum, hippocampus, and frontal cortex were selected for examination based on roles in sleep regulation and sensitivity to sleep disruption. For autophagy, we monitored the levels of various autophagic induction markers including beclin1, LC3II, and p62 as well as the levels of lysosomal associated membrane protein 1 and 2 (LAMP1/2) and the transcription factor EB (TFEB) which are critical for lysosome function and autophagy maturation stage. For the status of microglia and astrocytes, we determined the levels of Iba1 and GFAP in these brain regions. We also measured the levels of CRF and its cognate receptors 1 and 2 (CRFR1/2). Our results showed that 5 days of SF dysregulated autophagy in the striatum and hippocampus but not in the frontal cortex. Additionally, 5 days of SF activated microglia in the striatum but not in the hippocampus or frontal cortex. In the striatum, CRFR2 but not CRFR1 was significantly increased in SF-experienced mice. CRF did not alter its mRNA levels in any of the three brain regions assessed. Our findings revealed that autophagy processes are sensitive to short-term SF in a region-specific manner and suggest that autophagy dysregulation may be a primary initiator for brain changes and functional impairments in the context of sleep disturbances and disorders.

Caregivers' experiences of patients with moderate-stage Alzheimer's disease: a qualitative study

BACKGROUND

Caregivers experience challenges in the longest stage of Alzheimer disease, the moderate stage, due to all day demanded caregiving, added with neuropsychiatric symptoms, and communication difficulties. Supporting challenges of caregiving is more effective when specific needs are assessed and real-life experiences are appreciated. This study sought to explore caregivers' experiences and support needs for moderate-stage Alzheimer's disease patients.

METHODS

This study had a qualitative phenomenological design. In-depth, semi-structured interviews were conducted with 46 caregivers via face-to-face interviews. Following transcription, an analysis was done with Colaizzi's steps by coding and defining the main themes and subthemes.

RESULTS

Caregivers stated they faced difficulties in the care activities of patients and needed support. Three themes were identified: (i) changes related to Alzheimer's disease; (ii) change in caregivers' life; and (iii) support needs and coping strategies about the care process.

CONCLUSIONS

Current study confirmed that caregivers of moderate-stage Alzheimer's disease patients need proper support to cope with daily care activities and systems that help them overcome life challenges. The development of a system based on the stage-specific caregivers' need to decrease daily care challenges and overwhelming economic and emotional stress can be recommended.

Perceived health, caregiver overload and perceived social support in family caregivers of patients with Alzheimer's: Gender differences

Perceived health in caregivers is related to caregiver burden, psychological well-being and social support. Women perceive poorer health and are more likely than men to experience caregiver overload. The objectives of this study were to analyse perceived health, perceived social support and caregiver overload in family caregivers of patients with Alzheimer's disease, as well as to study the effect of the perceived social support as a mediating variable between perceived health and caregiver overload was also analysed, taking into account the caregivers' gender. A cross-sectional descriptive design was used. The sample consisted of 255 family caregivers of individuals with Alzheimer's disease in the Almería Health District (Spain). This study was conducted from January to December 2015. The caregivers' mean age was 55.35 years (SD = 12.35), with 85.5% (n = 218) being women and 14.5% (n = 37) being men. The following questionnaires were administered: Goldberg's General Health Questionnaire-28; the Caregiver Strain Index, measuring caregiver overload; and the Duke-UNC-11 functional social support questionnaire. Poor perceived health, high caregiver overload and high perceived social support were found. Differences in perceived health and perceived social support were significantly higher in women than in men. In women, perceived social support was a mediating variable between perceived health and family caregiver overload. This mediation was not observed in men. This study suggests that perceived social support influences the emotional well-being and the caregiver overload of family caregivers of patients with Alzheimer's. However, its effect differs according to gender. It would, therefore, be necessary to have an in-depth understanding of the variables determining these differences in family caregivers.

Contributors and Moderators of Quality of Life in Caregivers of Alzheimer´s Disease Patients

Aim and objective: This study aimed to identify the variables that contributed to Quality of Life (QoL) of Alzheimer's Disease (AD) caregivers, taking into consideration the caregiving context, stressors, role strains, and resources.Methods: The sample included 102 caregivers of AD patients who answered the following instruments: Depression, Anxiety and Stress Scale-21; Satisfaction with Social Support Scale; Revised Memory and Behavioral Problems Checklist; Family Communication and Satisfaction Scales; Spiritual and Religious Attitudes in Dealing with Illness; and Quality of Life in Alzheimer's Disease - Caregiver Version.Results: Caregivers who were employed, chose the caregiving role, and received help in caring showed better QoL. Also, being younger, less caregiving daily hours, caring for patients with less memory and behavior problems, lower distress, and family satisfaction predicted better QoL. Finally, spirituality was a moderator between family communication and QoL but not between family satisfaction and QoL.Conclusion: Caregiving-context variables (age, professional status, choosing to care, receiving help in the caregiving role and duration of daily care); role strains (family dissatisfaction); stressors (caregivers' distress and patients' memory and behavioral problems); and resources (spirituality) had an impact on caregivers' QoL emphasizing the adequacy of the Stress Process Model. Intervention should also focus on spirituality given its moderating role.

Family Relationships and Alzheimer's Disease: A Systematic Review

BACKGROUND

Family caregivers of people with Alzheimer's disease are the most important support in concrete personal and economic terms. Family dynamics play a fundamental role in the provision of informal caregiving benefits.

OBJECTIVE

This review aims to identify factors related to the family caregiving of relatives with Alzheimer's disease, taking specifically into account the construct of coping and expressed emotion.

METHODS

This is a systematic review including articles selected using search terms including "caregivers," "Alzheimer's," "family," and "relationship" in research databases. Findings were synthesized and categorized into themes.

RESULTS

A total of 454 abstracts were identified. Following screening, lateral searches, and quality appraisal, 36 studies were included for synthesis. A total of 5 themes were identified: burden; demographics; coping strategies; caregiver mental health; and family dynamics and expressed emotions.

CONCLUSION

The quality and level of evidence supporting each theme varied. We need further research into family dynamics ameliorating the caregiving and how to measure it.

Perception and attitude of the general population towards Alzheimer's disease in Jeddah, Saudi Arabia

There are many conflicting beliefs about Alzheimer's disease in the general population. Conducting a study on public awareness, attitude, and knowledge towards Alzheimer's disease is useful in decreasing discrimination and stigmatization. This study aims to determine the public perception and attitude towards Alzheimer's disease in Jeddah, Saudi Arabia. In addition, we aim to identify the religious and cultural beliefs about the causes and treatment of Alzheimer's disease in Saudi Arabia. This is a cross-sectional study that was conducted in malls and public places in Jeddah, Saudi Arabia. The instrument used in this study was a self-administered questionnaire that consists of 40 items. A total of 32 questions were included into the survey, which was subdivided into four sources of information that include general information about Alzheimer's disease, information about Alzheimer's disease in the society, general information about persons with Alzheimer's disease, and information about the care of persons with Alzheimer's disease. In addition, eight questions were used to collect information about the demographic profile of the participants. A total of 1698 individuals participated in the study. 1511 participants (89%) had heard about Alzheimer's disease before. Around 46% of the participants think that the cause of Alzheimer's disease is a brain disease and 44.9% think that is a normal part of aging. Approximately, 30% of the participants believe that Alzheimer's disease is treated with medications and 24.6% believe that there is no treatment. Around 30% of the participant think that the society treats persons with Alzheimer's disease with stigmatization. More than half of the participants (56.2%) think that persons with Alzheimer's disease should not be admitted to the nursing home. The results of the present study suggest that the perception of the general public of Alzheimer's disease is lagging behind. Many wrong beliefs were identified in the general public regarding the causes and management. The findings of our study suggest that more information about Alzheimer's disease would be valuable and beneficial for everyone. Awareness campaigns and public education are needed to increase the knowledge of the general public regarding several aspects of the disease including prevention, causes, and management. Dissemination of information about Alzheimer's disease should be of high priority. Increased awareness will lead to earlier detection of Alzheimer's disease and other dementia cases and appropriate care and management of those persons.

Predictor Factors of Perceived Health in Family Caregivers of People Diagnosed with Mild or Moderate Alzheimer's Disease

Caring for a person diagnosed with Alzheimer's disease has a negative impact on family caregivers' psychological health. This study examined the factors related to 'perceived health' and 'presence of new-onset mental health problems' in family caregivers of people diagnosed with mild and moderate Alzheimer's disease. A cross-sectional observational study carried out in Almeria's Healthcare District (Spain). A total of 255 family caregivers (42.4% cared for people with mild Alzheimer's disease and 57.6% cared for people with moderate Alzheimer's disease) participated in the study from January to December 2015. Mainly, caregivers were women (81.5% in the mild Alzheimer's disease group and 88.4% in the moderate Alzheimer's disease group), and their average age was 56.54 years (standard deviation (SD) = 13.13) and 54.47 years (SD = 11.71), respectively. Around 47% of the caregivers had been caring for the person with Alzheimer's between two and five years. The Goldberg General Health Questionnaire was used to measure perceived health and the presence of new-onset mental health problems. An exploratory descriptive analysis and a multivariate logistic regression analysis were conducted. For caregivers of people with mild Alzheimer's disease, 'perceived health' was related to 'perceived social support' (r = -0.21; p = 0.028), 'person's level of dependency' (r = -0.24, p = 0.05), 'severity of the person's neuropsychiatric symptoms' (r = 0.22; p = 0.05), and 'caregiver's emotional distress in response to the person's neuropsychiatric symptoms' (r = 0.22; p = 0.05). For caregivers of people with moderate Alzheimer's disease, 'perceived health' was related to 'perceived social support' (r = -0.31; p ˂ 0.01), 'presence of neuropsychiatric symptoms' (r = 0.27, p = 0.01), 'severity of the person's neuropsychiatric symptoms' (r = 0.32, p = 0.01) and 'caregiver's emotional distress in response to the person's neuropsychiatric symptoms' (r = 0.029; p = 0.01). The presence of new-onset mental health problems was detected in 46.3% (n = 50) of caregivers of people with mild Alzheimer's and 61.9% (n = 91) of caregivers of people with moderate Alzheimer's. When people are diagnosed with mild Alzheimer's disease, intervention programs for caregivers should aim to regulate emotions and promote positive coping strategies. When people are diagnosed with moderate Alzheimer's disease, intervention programs for caregivers must allow them to adapt to caregiving demands that arise with the progression of Alzheimer's disease.

Chronic sleep fragmentation shares similar pathogenesis with neurodegenerative diseases: Endosome-autophagosome-lysosome pathway dysfunction and microglia-mediated neuroinflammation

Aims

Insufficient sleep has been found to result in varying degrees of cognitive impairment and emotional changes. Sleep was reported probably responsible for cleaning metabolic wastes in brain by increasing extracellular bulk flow. Herein, we propose that chronic sleep insufficiency in young adult wild‐type mice is also linked with dysfunction of intracellular protein degradation pathways and microglia‐mediated neuroinflammation, which are potentially important mechanisms in the initiation of neurodegeneration.

Methods

We applied the chronic sleep fragmentation (CSF) model to induce chronic sleep insufficiency in wild‐type mice. After 2 months of CSF, cognitive function, amyloid‐β accumulation, dysfunction of endosome‐autophagosome‐lysosome pathway, and microglia activation were evaluated.

Results

Following CSF, impairment of spatial learning and memory, and aggravated anxiety‐like behavior in mice were identified by behavioral experiments. Increased intracellular amyloid‐β accumulation was observed in cortex and hippocampus. Mechanistically, CSF could significantly enhance the expression of Rab5 (early endosome marker), Rab7 (late endosome marker), as well as LC3B (autophagosome marker), and autophagy‐positive regulatory factors in brain detected by immunofluorescent staining and Western blot. In addition, activation of microglia was evident by enhanced CD68, CD16/32, and CD206 levels after CSF treatment.

Conclusions

Chronic sleep fragmentation could initiate pathogenetic processes similar to the early stage of neurodegeneration, including dysfunction of endosome‐autophagosome‐lysosome pathway and microglia‐mediated neuroinflammation. Our findings further strengthen the link between chronic sleep insufficiency and the initiation of neurodegeneration even if lack of genetic predisposition.

Communicating Health Information at the End of Life: The Caregivers' Perspectives

Health information and communication are key elements that allow patients and family members to make decisions about end-of-life care and guarantee a death with dignity. Objective: To understand caregivers' experiences regarding health information and communication during the illness and death of family members. Methods: This qualitative study was conducted in Andalusia based on the paradigm of hermeneutic phenomenology. Participants were caregivers who had accompanied a family member at the end of life for over 2 months and less than 2 years. Five nominal groups and five discussion groups were established, and 41 in-depth interviews with 123 participants were conducted. Atlas.ti 7.0 software was used to analyze the discourses. A comprehensive reading was carried out along with a second reading. The most relevant units of meaning were identified, and the categories were extracted. The categories were then grouped in dimensions and, finally, the contents of each dimension were interpreted and described given the appropriate clarifications. Results: Four dimensions of the dying process emerged: differences in caregivers' perceptions of information and communication, a conspiracy of silence, consequences of the absence or presence of information, and the need for a culture change. Conclusions: Poor management of health information and communication at the end of life increased the suffering and discomfort of patients and their families. The culture of denying and avoiding death is still present today. A change in education about death would better enable health professionals to care for patients at the end of life.
