Caregivers' perspectives and experiences of withdrawing acetylcholinesterase inhibitors and memantine in advanced dementia: a qualitative analysis of an online discussion forum

Thematic Analysis of Alzheimer's Medication Management Discussion in a Non-Moderated Online Forum

BACKGROUND

Managing medications for Alzheimer's disease and related dementias is challenging for caregivers. Information about caregivers' strategies to manage these challenges is needed to inform intervention development.

OBJECTIVE

This study aimed to understand caregivers' medication management experiences by analyzing online community discussions.

METHODS

Posts were extracted from the ALZConnected® Forum using keywords "medication" and "drug" via web scraping. The researchers applied thematic analysis.

RESULTS

Four major themes emerged: (1) role transition of medication management responsibilities, (2) caregivers' uncertainty about medication purpose and values, (3) conflicts between the care recipients and caregivers, and (4) difficulty accessing and affording medications.

CONCLUSIONS

The experiences shared on a non-moderated, unstructured online forum indicate that medication management is challenging and overwhelming for caregivers of people living with Alzheimer's disease and related dementias. Since this is a progressive disease with various stages and changing needs, caregivers' strategies vary and are often limited by available resources and support. Health care providers should offer training and support for caregivers to navigate the transfer of medication management responsibilities and changing care needs as the disease progresses.

Carers' experiences and perspectives of the use of anticholinergic medications in people living with dementia: Analysis of an online discussion forum

INTRODUCTION

There is concern about the use of anticholinergic medications in people living with dementia (PLWD). Such medicines may increase cognitive decline and may be associated with higher mortality in PLWD who take these medicines. The aim of this study was to analyse data from an online dementia discussion forum to explore the experiences and perspectives of PLWD and carers about the use of anticholinergic medicines in this population.

METHODS

Following receipt of ethical approval, archived discussions (posts) from Dementia Talking Point, a fully public online forum for anyone affected by dementia, created and maintained by the Alzheimer's Society, were searched from the date of inception to January 2022 using a range of search terms including commonly used anticholinergic medicines. Posts, including any of the search terms, were assessed for relevance and analysed using inductive thematic analysis.

RESULTS

Five hundred and fifty unique posts were analysed, all of which had been provided by carers, with no posts attributed to PLWD. The themes that encompassed carers' experiences were (1) motivators of prescribing, (2) perspectives on the process of prescribing and (3) the outcomes of prescribing. The dominant motivator of prescribing was the management of noncognitive symptoms, pre- and postdiagnosis of dementia. Carers' perspectives on the process of prescribing were informed by an assessment of the risk-benefit of starting a medication and shared decision-making between the carer and healthcare professional to a greater or lesser degree. The outcomes of prescribing were observing the effects of the medicines, which in turn influenced whether prescribing was reviewed and continued unchanged, continued but amended, reinitiated if the medicine had been previously stopped or discontinued (the process of deprescribing).

CONCLUSION

This study has provided unique insights into carers' experiences and perspectives about the use of anticholinergic medications in PLWD, highlighting how commonly these medications are prescribed for PLWD and carers' concerns about their use. There is a clear need for carers and PLWD to receive information about these medicines and healthcare professionals to consider how to optimise the use of these medicines to avoid adverse effects.

PATIENT OR PUBLIC CONTRIBUTION

This work was informed by findings from previous research studies focusing on optimising medicine use for people with dementia in primary care, in which interviews were conducted with PLWD, their carers and primary healthcare professionals. Although not strictly patient and public involvement, we utilised the feedback provided by key stakeholders to inform the research questions and aim/objectives of this study.

Emotional word use in informal carers of people living with dementia: A linguistic analysis of online discussion forums (Preprint)

Background

Informal dementia care is uniquely stressful and necessitates effective methods of identifying and understanding the needs of potentially at-risk carers so that they can be supported and sustained in their roles. One such method is examining carers’ engagement in online support platforms. Research has explored emotional word use on online discussion forums as a proxy for underlying emotional functioning. We are not aware of any research that has analyzed the content of posts on discussion forums specific to carers of people living with dementia in order to examine their emotional states.

Objective

We addressed the following research questions: (1) To what extent does emotional language use differ between carers of people living with dementia and noncarers? (2) To what extent does emotional language use differ between spousal and parental carers? (3) To what extent does emotional language use differ between current and former carers?

Methods

We used the Linguistic Inquiry and Word Count (LIWC) program to examine emotional word use on a UK-based online forum for informal carers of people living with dementia and a discussion forum control group. Carers were separated into different subgroups for the analysis: current and former, and spousal and parental.

Results

We found that carers of people living with dementia used significantly more negative, but not positive, emotion words than noncarers. Spousal carers used more emotion words overall than parental carers, specifically more negative emotion words. Former carers used more emotional words overall than current carers, specifically more positive words.

Conclusions

The findings suggest that informal carers of people living with dementia may be at increased risk of negative emotional states relative to noncarers. Greater negativity in spousal carers may be explained by increased caregiver burden, whereas greater positivity in former carers may be explained by functional relief of caregiving responsibilities. The theoretical/applied relevance of these findings is discussed.

What Will It Mean for Me? Perceptions of the ECFMG 2023 Accreditation Requirement from an Online Forum

In 2010, the Educational Commission for Foreign Medical Graduates (ECFMG) announced that as of 2023, physicians applying to train and practice in the United States will be required to graduate from a medical school that has been accredited using criteria such as those developed by the World Federation for Medical Education. This study analyzed posts on the Student Doctor Network (SDN) online forum that refer to this accreditation requirement to investigate how it has been perceived and understood by current and prospective medical students. A keyword search of relevant terms was used to identify posts discussing the accreditation requirement on the SDN online forum, which were subjected to thematic analysis. There were a total of 83 posts from 49 distinct user accounts between May 2012 and January 2020. Seven themes were identified in total; four whose overall purpose was to seek or offer advice and three whose overall purpose was commentary. Themes relating to advice included applications and admissions, future career planning, personal circumstances, and countryspecific issues. Themes relating to commentary included the accreditation requirement policy itself, the potential implications of the requirement, and the educational quality of non-U.S. medical schools. Only half of web links on these posts were to the ECFMG website for official information about the requirement. Although a variety of different perspectives about the ECFMG accreditation requirement were expressed on an online forum for student doctors, the overall number of posts was low, which suggests that the requirement has not been a frequent topic of discussion on this platform. The insights gained from posts suggest personal opinions about the requirement and consequences for individual student application and career choices were the main areas of interest. Signposting to official information channels may help to raise awareness about the requirement and tackle areas of uncertainty and confusion about its implementation.

Beta-Caryophyllene, a CB2R Selective Agonist, Protects Against Cognitive Impairment Caused by Neuro-inflammation and Not in Dementia Due to Ageing Induced by Mitochondrial Dysfunction

BACKGROUND

Dementia is a neurodegenerative disorder majorly evidenced by cognitive impairment. Although there are many types of dementia, the common underlying etiological factors in all the types are neuro-inflammation or aging induced apoptosis. β-caryophyllene, a cannabinoid type-2 receptor agonist, has been reported to have promising neuroprotective effects in cerebral ischemia and neuro-inflammation.

OBJECTIVE

In the present study, we evaluated the effects of β-caryophyllene against animal models of dementia whose etiology mimicked neuro-inflammation and aging.

METHODS

Two doses (50 and 100 mg/kg of body weight) of β-caryophyllene given orally were tested against AlCl₃-induced dementia in male Sprague Dawley (SD) rats using the Morris water maze test. Subsequently, the effect of the drug was assessed for episodic memory in female SD rats using novel object recognition task in doxorubicin-induced neuro-inflammation and chemobrain model. Moreover, its effects were evaluated in D-galactose-induced mitochondrial dysfunction leading to dementia.

RESULTS

β-caryophyllene, at both doses, showed significant improvement in memory when assessed using parameters like target quadrant entries, escape latency and path efficiency in the Morris water maze test for spatial memory. In the doxorubicin-induced chemobrain model, β-caryophyllene at 100 mg/kg significantly elevated acetylcholinesterase and catalase levels and lowered lipid peroxidation compared to the disease control. In the novel object recognition task, β-caryophyllene at 100 mg/kg significantly improved recognition index and discrimination index in the treated animals compared to the disease control, with a significant increase in catalase and a decrease in lipid peroxidation in both hippocampus and frontal cortex. However, in the D-galactose-induced mitochondrial dysfunction model, β-caryophyllene failed to show positive effects when spatial memory was assessed. It also failed to improve D-galactose-induced diminished mitochondrial complex I and II activities.

CONCLUSION

Hence, we conclude that β-caryophyllene at 100 mg/kg protects against dementia induced by neuro-inflammation with no effect on neuronal aging induced by mitochondrial dysfunction.
