Quality of life and caregiver burden in familial frontotemporal lobar degeneration: Analyses of symptomatic and asymptomatic individuals within the LEFFTDS cohort

A comprehensive review on frontotemporal dementia: its impact on language, speech and behavior

Frontotemporal dementia (FTD) is a progressive neurodegenerative disorder defined by the selective deterioration of the frontal and temporal lobes of the brain. This comprehensive review explored the effect of FTD on language, speech, and behavior. Early symptoms include difficulty in word finding, reduced speech output, and comprehension deficits, often leading to aphasia. The study discussed the profound behavioral changes observed in FTD patients, including apathy, disinhibition, compulsive behaviors, and loss of empathy, the importance of an accurate and early diagnosis, and its challenges. We even reviewed the potential for targeted therapies and the essential role of multidisciplinary care in managing the language, speech, and behavioral aspects of FTD. By examining objective data and comprehensive research on the subject, this study offers valuable insights into FTD's profound effects on language, speech, and behavior, assisting in improved clinical management and potential therapeutic strategies for this devastating condition.

Psychological and social impacts of frontotemporal dementia on caregivers and family members - A systematic review

INTRODUCTION

Frontotemporal dementia (FTD) may impose substantial psychological and social burdens on caregivers and family members that are unique from other forms of dementia due to its distinctive clinical characteristics. This systematic review investigated these impacts on caregivers and family members.

METHODS

A systematic search was conducted in the PubMed, Cochrane Library and Embase databases for relevant articles published from database inception to 23 March 2023. The methodological quality of the articles was evaluated using a checklist.

RESULTS

Thirty-six articles (six qualitative and thirty quantitative), including 5129 participants, were included in this review. Like other forms of dementia, FTD caregivers had significant caregiver burden levels and psychological impacts. Caregiver burden was associated with behavioural symptoms (e.g., apathy and disinhibition) and motor symptoms. The costs of caring for a patient with FTD were found to be higher than those for Alzheimer's disease. FTD patients often face challenges in obtaining a correct diagnosis and experience significant delays and multiple misdiagnoses. Healthcare professionals may also be less familiar with FTD than with Alzheimer's, leading to delayed diagnosis. This can cause considerable stress and deprive patients and caregivers of early intervention.

CONCLUSION

FTD is associated with significant costs and caregiver burden levels, and the difficulties faced by caregivers and family members can be unique and challenging in different aspects when compared to other forms of dementia. Better education about FTD for family members and healthcare professionals is required to improve the quality of life for both patients and caregivers, and more support needs to be provided at all stages of the disease.

'There's no straight line…' a consumer-informed intervention for FTD family care partners: the STELLA-FTD pilot study

OBJECTIVES

Behavioral symptoms and communication challenges are particularly apparent in frontotemporal degenerative (FTD) dementias. There is a paucity of psychoeducation programming specifically tailored to the needs of families with FTD. We revised an existing intervention to meet the needs of these families.

METHODS

We used a quasi-experimental approach. In Phase 1, we sought consumer input about an existing intervention. In Phase 2, we modified the intervention based on the qualitative findings from Phase 1 and tested the revised intervention (STELLA-FTD) for feasibility, acceptability and early-stage efficacy. Outcome for Phase 2 included feasibility data and care partner reactivity to upsetting behaviors. Secondary outcomes included data from unobtrusive sleep monitoring. An inductive analysis of transcripts from the Phase 2 STELLA-FTD focus group provides guidance for future revisions.

RESULTS

Fifteen family care partners participated in the Phase 1 focus groups; sixteen care partners enrolled in Phase 2. Testing in Phase 2 revealed that the care partners found our consumer-informed revised intervention both feasible and acceptable. The post-intervention findings suggest STELLA-FTD has the potential to reduce care partner reactivity to upsetting behaviors and to decrease care partner burden. Sleep did not change over the 8-week intervention.

CONCLUSIONS

The revised STELLA-FTD intervention was found to be feasible and acceptable, and has potential to improve care partner burden for families living with FTD. Providing the intervention via telehealth maximized access and engaged rehabilitation specialists in providing disease management content. Future revisions will include examination of efficacy and mechanism of action (OHSU IRB # 00022721, ClinicalTrials.gov NCT05338710).

Frontotemporal lobar degeneration

Frontotemporal lobar degeneration (FTLD) is one of the most common causes of early-onset dementia and presents with early social-emotional-behavioural and/or language changes that can be accompanied by a pyramidal or extrapyramidal motor disorder. About 20-25% of individuals with FTLD are estimated to carry a mutation associated with a specific FTLD pathology. The discovery of these mutations has led to important advances in potentially disease-modifying treatments that aim to slow progression or delay disease onset and has improved understanding of brain functioning. In both mutation carriers and those with sporadic disease, the most common underlying diagnoses are linked to neuronal and glial inclusions containing tau (FTLD-tau) or TDP-43 (FTLD-TDP), although 5-10% of patients may have inclusions containing proteins from the FUS-Ewing sarcoma-TAF15 family (FTLD-FET). Biomarkers definitively identifying specific pathological entities in sporadic disease have been elusive, which has impeded development of disease-modifying treatments. Nevertheless, disease-monitoring biofluid and imaging biomarkers are becoming increasingly sophisticated and are likely to serve as useful measures of treatment response during trials of disease-modifying treatments. Symptomatic trials using novel approaches such as transcranial direct current stimulation are also beginning to show promise.

How gender matters in demanding caring for a spouse with young-onset dementia. A narrative study

BACKGROUND

The gendered aspects of extraordinary demanding spousal caring for people with young-onset dementia have been scarcely researched.

AIM

To analyze spouses' experiences of the meaning, content, and effort of intensive caring for spouses/partners with young-onset frontotemporal dementia (YO-FTD), concentrating on a female perspective.

METHOD

A qualitative Norwegian study using narrative interviews with 10 wives and 6 husbands were conducted in 2014 and 2015.

FINDINGS

The analysis resulted in four gendered main themes: Different caregiving periods, Distancing: experiencing a transformed spouse and relationship, Social isolation, and Needing assistance and relief. A case analysis of wives' and men's stories was applied, especially focusing on a wife's story, to examine the detailed interrelationships between life situation, caring demands, experiences, and reactions. Spousal care is influenced by gendered caring norms and roles. The study finds marked differences between wives and husbands in the meaning, content and sustainability of care, and needs for support vary. Wives endured more stress longer than husbands, with a greater emotional impact and negative health consequences, and their needs are more easily neglected. Husbands presented their needs more efficiently and obtained public relief earlier.

CONCLUSION

Women may need more support earlier during different stages of caring for a spouse with YO-FTD. They need gender sensitive person-centered support to live their own lives and preserve their selves.

Genetic counseling and diagnostic genetic testing for familial amyotrophic lateral sclerosis and/or frontotemporal dementia: A qualitative study of client experiences

Genetic counseling and diagnostic genetic testing is part of the multidisciplinary care of people with amyotrophic lateral sclerosis (ALS, commonly called motor neurone disease, MND) and frontotemporal dementia (FTD). We explored client experiences of genetic counseling and diagnostic testing to inform the care of future families. Semi-structured interviews with individuals with ALS/MND/FTD or their relatives were conducted. The study was designed to include a wide variety of participants with varying disease status and abilities. Genetic counseling and diagnostic testing experiences were explored using interpretive description methodology. Bioecological theory was used as the framework for the reflexive thematic analysis. Eighteen individuals with ALS/MND/FTD or their relatives from 13 Australian families participated. Three themes were identified: sharing knowledge, (un)supportive care, and 'circumstance is everything'. Consistent with bioecological theory, one's genetic counseling experience was informed by individual circumstances, time, and proximal factors. These informed the level of information and support required in the genetic counseling process. Although some client circumstances cannot be changed, efforts could be made to enhance genetic counseling experiences by improving interactions between the client and their care team. Some clients may benefit from further discussions regarding the familial implications of genetic testing, and greater support with family communication. Clients' needs were derived from the data and will contribute to genetic counseling consensus guidelines.

The positive aspects of caregiving in dementia: A scoping review and bibliometric analysis

Purpose

The increasing incidence of dementia and home-based care exposes family caregivers to a variety of challenges as they endure strong stressors underlying the caregiver role. Despite growing publications on positive aspects of caregiving in dementia, few studies have identified the extent, nature, and gaps in the existing literature based on a holistic view. The aim was to identify key issues and a holistic view of literature regarding positive aspects of caregiving in dementia.

Methods

A scoping review was conducted underlying a five-stage framework by Arksey and O'Malley. Five databases, including PubMed, CINAHL, PsycINFO, Embase, and Web of Science, were searched, and references were listed accordingly. Data were extracted by two researchers, comprising article characteristics, forms of positive aspects of caregiving and measurements, theories, forms of dementia and family caregiver, and keywords. Descriptive statistics and narrative synthesis were performed to analyze data. Network analysis of keywords and authors was conducted using VOSviewer software. Word cloud analysis of titles was examined by NVivo.

Results

The review included 230 articles, most of which have been published in the last decade (62.61%). Most articles (40.00%) were contributed by the United States. Cross-sectional studies (41.30%) ranked first, followed by qualitative studies (13.48%). Over a quarter of the literature (28.26%) focused on Alzheimer's care, and nearly 90% included all forms of family caregivers. The Positive Aspects of Caregiving Scale and stress coping theory were most frequently cited. Four clusters dominated by Casey D, Quinn C, Joling KJ, and Teahan A were identified in the network of co-authorship. Six themes were identified: current situations of caregiver experiences, antecedents, consequences, measurement development, effects of interventions, and the concept of positive aspects of caregiving. These were in line with network analysis of keywords and word cloud analysis of titles.

Conclusions

Positive aspects of caregiving in dementia have been widely concerned, but most of them are based on the theory of the negative stress process and are limited to current situations and influencing factors. Building theories focus on the positive aspects of caregiving, subsequently developing a comprehensive measurement and effective interventions, should be further studied.

The contribution of behavioral features to caregiver burden in FTLD spectrum disorders

INTRODUCTION

Caregivers of patients with frontotemporal lobar degeneration (FTLD) spectrum disorders experience tremendous burden, which has been associated with the neuropsychiatric and behavioral features of the disorders.

METHODS

In a sample of 558 participants with FTLD spectrum disorders, we performed multiple-variable regressions to identify the behavioral features that were most strongly associated with caregiver burden, as measured by the Zarit Burden Interview, at each stage of disease.

RESULTS

Apathy and disinhibition, as rated by both clinicians and caregivers, as well as clinician-rated psychosis, showed the strongest associations with caregiver burden, a pattern that was consistent when participants were separated cross-sectionally by disease stage. In addition, behavioral features appeared to contribute most to caregiver burden in patients with early dementia.

DISCUSSION

Caregivers should be provided with early education on the management of the behavioral features of FTLD spectrum disorders. Interventions targeting apathy, disinhibition, and psychosis may be most useful to reduce caregiver burden.

Toward genetic counseling practice standards for diagnostic testing in amyotrophic lateral sclerosis and frontotemporal dementia

Objective: Genetic counseling and diagnostic genetic testing are considered part of the multidisciplinary care of individuals with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). We aimed to investigate the ideal components of genetic counseling for ALS/FTD diagnostic testing amongst various stakeholders using an online, modified Delphi survey. Methods: Experts in genetic counseling and testing for ALS/FTD were purposively then snowball recruited and included genetic health professionals, health professionals outside of genetics and consumer experts (patients, relatives, and staff representatives from ALS/FTD support organizations). First-round items were informed by two systematic literature reviews and qualitative interviews with patients and families who had experienced diagnostic testing. Analysis of each round informed the development of the subsequent round and the final results. Results: Forty-six experts participated in the study, 95.65% completed both rounds. After round one, items were updated based on participant responses and were presented again for consensus in round two. After round two, a high level of consensus (≥80% agreement) was achieved on 16 items covering various topics related to genetic counseling service delivery, before and after diagnostic testing is facilitated. Conclusions: Genetic counseling for individuals with ALS/FTD and their families should include the provision of client-centered counseling, education and support throughout. The items developed are adaptable to varied healthcare settings and may inform a standard of genetic counseling practice for health professionals who facilitate testing and counseling discussions. This area of work is timely, given demand for testing is likely to increase as more genotype-driven clinical trials become available.

Patient and Relative Experiences and Decision-making About Genetic Testing and Counseling for Familial ALS and FTD: A Systematic Scoping Review

Genetic testing and counseling is an emerging part of care for patients with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) and their families. This scoping review aimed to map patients' and relatives' experiences of genetic testing and counseling for familial ALS and FTD and the factors influencing their decision to proceed with testing or counseling. Informed by the Joanna Briggs Institute methodology, 5 databases were systematically searched. Thirty studies from 39 references were included. A descriptive numerical summary analysis and narrative synthesis was conducted. Mostly positive diagnostic testing experiences were reported, but issues arose due to progressive disease and discordant results. Predictive testing impacted at-risk relatives, regardless of the result received, and psychosocial sequelae ranged from relief to guilt, worry or contemplating suicide. Four reproductive testing experiences were reported. Personal, familial and practical factors, and the lived experience of disease, informed decision-making. Greater uncertainty and complexity may be faced in familial ALS/FTD than in other late-onset neurodegenerative diseases due to clinical and genetic heterogeneity, and testing limitations. Genetic counseling models of care should consider this difference to ensure that individuals with, or at risk of, ALS/FTD are effectively managed. Implications for research and practice are discussed.

Metaphors for the Meaning of Caring for a Spouse with Dementia

Background

Spouses of people with young-onset frontotemporal dementia (YO-FTD) (age 65 years or younger) encounter special challenges. The diagnosis is scarcely known; the early onset is unexpected; and the disease is characterized by symptoms varying from those of other types of dementia. Caring implies increasing hardships, which can be difficult to communicate to others when applying for support. Metaphors create and communicate meaning and are increasingly used in health care and health interventions as ways to better understand the situation.

Aim

To examine the experiences of spouses of people with YO-FTD and their needs for care and support as expressed through metaphors in narratives of their experiences during the development of the dementia.

Methods

Qualitative interviews with 16 informants (ten women, six men) were conducted in 2014/2015. They were recruited from seven memory clinics, one municipality dementia team, and a nursing home. Steger’s three-step method for analyzing metaphors was applied.

Findings

The core metaphors cover experiences of the dementia and the transformation of the spouse, changed roles and relationships between spouses, the transformation of the self, a radical turn of existential life, and relationships with others. Metaphors are words and phrases used to talk about complicated, contradictory, shameful, and/or normatively difficult feelings and reactions as caring spouses. The open themes and, at the same time, provide verbal shields and defences. Metaphors are especially effective for expressing the strength of the reactions in caring as emotional work and are tools for mastering emotions and challenges in life.

Conclusion

Metaphors give insights into the significant experiences of spouses of partners with YO-FTD and offer personnel in health services a better understanding of their needs for tailored support and help.
