Enhancement of carer skills and patient function in the non-pharmacological management of frontotemporal dementia (FTD): A call for randomised controlled studies

Rehabilitation Services for Young-Onset Dementia: Examples from High- and Low-Middle-Income Countries

The WHO Dementia Global Action Plan states that rehabilitation services for dementia are required to promote health, reduce disability, and maintain quality of life for those living with dementia. Current services, however, are scarce, particularly for people with young-onset dementia (YOD). This article, written by an international group of multidisciplinary dementia specialists, offers a three-part overview to promote the development of rehabilitation services for YOD. Firstly, we provide a synthesis of knowledge on current evidence-based rehabilitative therapies for early-onset Alzheimer's disease (EOAD), behavioural variant frontotemporal dementia (bvFTD), primary progressive aphasia (PPA), and posterior cortical atrophy (PCA). Secondly, we discuss the characteristics of rehabilitation services for YOD, providing examples across three continents for how these services can be embedded in existing settings and the different roles of the rehabilitation multidisciplinary team. Lastly, we conclude by highlighting the potential of telehealth in making rehabilitation services more accessible for people with YOD. Overall, with this paper, we aim to encourage clinical leads to begin introducing at least some rehabilitation into their services, leveraging existing resources and finding support in the collective expertise of the broader multidisciplinary dementia professional community.

Frontotemporal Dementia Knowledge Scale: Development and Preliminary Psychometric Properties

OBJECTIVE

Frontotemporal dementia (FTD) accounts for ∼10% of dementia cases and is the most common cause of early-onset dementia. However, no well-validated instrument currently exists to measure knowledge about FTD. In this study, we used systematic scale development procedures to create a scale to measure knowledge of FTD based on a contemporary understanding of the disease.

METHODS

Standard scale development methods were used to create items and evaluate their psychometric properties. A total of 72 health care professionals and 102 caregivers of people with FTD responded to items measuring FTD knowledge, general dementia knowledge, crystallized intelligence, experience with FTD, and demographic information.

RESULTS

The Frontotemporal Dementia Knowledge Scale (FTDKS) contains 18 items that cover key, basic knowledge about FTD in the domains of risk factors, symptoms, course, caregiving, and treatment. The scale uses a 4-point True/False format with a Don't Know option and takes ∼5 minutes to complete. In the current sample the FTDKS had good psychometric properties in terms of reliability and validity.

IMPLICATIONS

The FTDKS can be used with health care professionals and caregivers of people with FTD to assess their knowledge about the disease. The scale may be useful to evaluate knowledge in clinical care and educational program contexts.

Positive behaviour support in frontotemporal dementia: A pilot study

Frontotemporal dementia (FTD) is a progressive neurodegenerative brain condition clinically characterized by marked changes in behaviour that impact the individuals' relationships and community participation, and present challenges for families. Family carers of individuals with FTD find apathy and disinhibition particularly challenging leading to high levels of stress and burden. Positive behaviour support (PBS) as a behaviour intervention framework has never been trialled in FTD. This pilot study examined the functional basis of apathetic and disinhibited behaviours in four FTD dyads and explored the acceptability of a PBS intervention. The PBS programme was provided by an occupational therapist in the participants' homes. Measures collected at baseline and post-intervention (M = 3.9 months) assessed: function of behaviours, challenging behaviours, and qualitative outcomes pertaining to the acceptability of the PBS approach. PBS was an acceptable intervention for all four dyads. "Sensory" and "tangible" were the most common functions contributing to the maintenance of behaviour changes, and aspects of apathetic and disinhibited behaviours improved following intervention. This study demonstrates the acceptability and potential benefit of a PBS programme to provide support in FTD. A more rigorous trial will be an important next step in developing improved services tailored to the needs of this unique population.

The tailored activity program (TAP) to address behavioral disturbances in frontotemporal dementia: a feasibility and pilot study

PURPOSE

To explore the feasibility of implementing the Tailored Activity Program with a cohort of people with frontotemporal dementia and their carers (dyads).

METHODS

The Tailored Activity Program is an occupational therapy based intervention that involves working collaboratively with family carers and prescribes personalized activities for behavioral management in people with dementia. Twenty dyads randomized into the study (Tailored Activity Program: n = 9; Control: n = 11) were assessed at baseline and 4-months. Qualitative analyzes evaluated feasibility and acceptability of the program for the frontotemporal dementia cohort, and quantitative analyzes (linear mixed model analyzes, Spearman's rho correlations) measured the impact of the program on the dyads.

RESULTS

The Tailored Activity Program was an acceptable intervention for the frontotemporal dementia dyads. Qualitative analyses identified five themes: "carer perceived benefits", "carer readiness to change", "strategies used by carer to engage person with dementia", "barriers to the Tailored Activity Program uptake/implementation", and "person with dementia engagement". Quantitative outcomes showed an overall reduction of behavioral symptoms (F_18.34 = 8.073, p = 0.011) and maintenance of functional performance in the person with dementia (F_18.03 = 0.375, p = 0.548).

CONCLUSIONS

This study demonstrates the potential for using an activity-based intervention such as the Tailored Activity Program in frontotemporal dementia. Service providers should recognize that while people with frontotemporal dementia present with challenging issues, tailored therapies may support their function and reduce their behavioral symptoms. Implications for rehabilitation The Tailored Activity Program is an occupational therapy based intervention that involves prescribing personalized activities for behavioral management in dementia. The Tailored Activity Program is an acceptable and feasible intervention approach to address some of the unique behavioral and functional impairments inherent in frontotemporal dementia.

Enhancing caregivers' understanding of dementia and tailoring activities in frontotemporal dementia: two case studies

PURPOSE

The purpose of this study is to describe the intervention process and results of the Tailored Activities Program (TAP) in two people diagnosed with Frontotemporal Dementia (FTD).

METHOD

TAP is an occupational therapy (OT) community-based intervention program that prescribes personalised activities to reduce difficult behaviours of dementia. The OT works with carers over a 4-month period (assessment, activity prescription and generalisation of strategies). Study measures were collected (blind researcher) pre- and post-intervention: cognition, functional disability, behavioural symptoms and Caregiver Confidence and Vigilance.

RESULTS

A 51-year-old woman with behavioural-variant FTD could consistently engage in more activities post-intervention, with scores indicating improvements to behaviour, function and caregiver confidence. A 63-year-old man with semantic variant FTD engaged well in the prescribed activities, with scores reflecting reduced carer distress regarding challenging behaviours and improved caregiver vigilance.

CONCLUSIONS

TAP is efficacious in FTD, allowing for differences in approach for FTD subtype, where behavioural symptoms are very severe and pervasive.

IMPLICATIONS FOR REHABILITATION

The Tailored Activities Program is an intervention which can be tailored to account for unique behavioural and language profiles inherent across frontotemporal dementia (FTD) subtypes. Maintaining a flexible approach when applying an intervention in FTD allows for tailoring to individual case variability within FTD subtypes.
