Experiences of apathy in people with Parkinson's disease: a qualitative exploration

A qualitative examination of apathy and physical activity in Huntington's and Parkinson's disease

Aim: In Huntington's disease (HD) and Parkinson's disease (PD), apathy is a frequently cited barrier to participation in physical activity. Current diagnostic criteria emphasize dissociable variants of apathy that differentially affect goal-directed behavior. How these dimensions present and affect physical activity in HD and PD is unknown. Methods: Using a qualitative approach, we examined the experience of apathy and its impact on physical activity in 20 people with early-manifest HD or idiopathic PD. Results: Two major themes emerged: the multidimensionality of apathy, including initiation or goal-identification difficulties, and the interplay of apathy and fatigue; and facilitators of physical activity, including routines, safe environments and education. Conclusion: Physical activity interventions tailored to apathy phenotypes may maximize participant engagement.

Apathy in Parkinson's Disease: A Retrospective Study of Its Prevalence and Relationship With Mood, Anxiety, and Cognitive Function

Apathy is thought to be an important clinical feature of Parkinson's disease (PD). However, its prevalence ranges greatly across studies because of differing definitions, assessment tools, and patient inclusion criteria. Furthermore, it remains unclear how the presentation of apathy in PD is related to mood disorder and/or cognitive impairment. This study sought to examine the prevalence of a pure apathy syndrome in PD, distinct from both depression and anxiety, and reveal its associated cognitive profile. A retrospective study was performed on 177 PD patients who had completed measures of apathy [Apathy Evaluation Scale (AES)] and mood functioning [Hospital Anxiety and Depression Scale (HADS)] and had undergone extensive neuropsychological assessment, using measures of intellectual functioning, memory, executive function, attention, language, visual processing, and cognitive speed; 14.7% of the sample indicated clinically significant levels of apathy, but this nearly always co-presented with depression and/or anxiety, with cases of "pure" apathy very rare (2.8%). On extensive cognitive assessment, patients with mood disorder performed worse on a measure of non-verbal intellectual functioning, but patients with additional apathy or apathy only demonstrated no further losses. The syndrome of apathy in PD greatly overlaps with that of depression and anxiety, suggesting that apathy in PD may be in large an epiphenomenon of mood disorder, with no specific neuropsychological features.

"He Just Doesn't Want to Get Out of the Chair and Do It": The Impact of Apathy in People with Dementia on Their Carers

Apathy, defined as a lack of motivation, is a prevalent and persistent behavioural and psychological symptom of dementia. Limited research suggests that apathy is associated with increased carer burden, but there are no studies investigating carers’ subjective experiences of apathy. This study aimed to fill this gap and explore the lived experience of apathy in dementia from the perspectives of the people with dementia and their carers. This article reports on the carers’ perspectives. Six dyads of people with dementia and carers participated in semi-structured interviews, which were analysed using interpretative phenomenological analysis. Three superordinate themes were identified: (1) achieving a balance of conflicting emotions—the challenges of apathy led to feelings of guilt, acceptance, and frustration; (2) new roles imposed by caring, which involved taking on new responsibilities and promoting remaining interests of person with dementia; and (3) having a life of one’s own—coping with apathy by talking to others, and spending time away from the caring role. This study highlighted that carers are caught in a struggle between wanting to involve the person with dementia in decisions and finding that they cannot if they want to overcome the hurdle of apathy. Implications of this study suggest that a wider understanding of apathy at a societal level could lead to the provision of a helpful forum for carers to share their experiences.

The Experience of Apathy in Dementia: A Qualitative Study

We aimed to explore and gain an understanding into how people with dementia experience apathy, and consequently suggest effective interventions to help them and their carers. Twelve participants (6 dyads of 6 people with dementia and their family carers) were recruited from “memory cafes” (meeting groups for people with dementia and their families), social groups, seminars, and patient and public involvement (PPI) meetings. People with dementia and their carers were interviewed separately and simultaneously. Quantitative data were collected using validated scales for apathy, cognition, anxiety, and depression. The interviews were semi-structured, focusing on the subjective interpretation of apathy and impacts on behaviour, habits, hobbies, relationships, mood, and activities of daily living. Interviews were recorded and transcribed. Transcripts were analysed using interpretative phenomenological analysis (IPA), which generated codes and patterns that were collated into themes. Four major themes were identified, three of which highlighted the challenging aspects of apathy. One described the positive aspects of the individuals’ efforts to overcome apathy and remain connected with the world and people around them. This study is the first to illustrate the subjective experience of apathy in dementia, portraying it as a more complex and active phenomenon than previously assumed. Apathy and its effects warrant more attention from clinicians, researchers, and others involved in dementia care.

Psychological Interventions for People with Huntington's Disease: A Call to Arms

BACKGROUND

Although Huntington's disease (HD) can cause a wide range of psychological difficulties, no review has ever been carried out on the range of psychological interventions adopted with this population.

OBJECTIVE

To scope the literature on psychological interventions for psychological difficulties in people affected by HD.

METHODS

A systematic scoping review was performed across MEDLINE, PsycINFO, CINAHL, Academic Search Ultimate, and Cochrane Library up to 1 March 2020.

RESULTS

From an initial return of 1579 citations, a total of nine papers were considered eligible for review. These included a qualitative investigation, three case studies, two case series, two uncontrolled pretest-posttest designs, and only one randomised control trial (RCT). Despite the wide range of psychological difficulties which can be experienced by people affected by the HD gene expansion, the adopted interventions only accounted for five main psychological outcomes (anxiety, apathy, depression, irritability, and coping). Further discussion and suggestions for future research are provided for each outcome.

CONCLUSION

The current literature on psychological interventions in people affected by HD is extremely limited both in terms of methods and addressed clinical outcomes. Consequently, no conclusions can be offered yet as to which psychological therapy may help this population. As further more comprehensive research is urgently needed for this group, the ultimate aim of the present review is to act as a call to arms for HD researchers worldwide to help shed light on the most effective way to translate psychological theory into practice for the benefit of people affected by HD.

Apathy as a behavioural marker of cognitive impairment in Parkinson's disease: a longitudinal analysis

Background

Understanding the longitudinal course of non-motor symptoms, and finding markers to predict cognitive decline in Parkinson’s disease (PD), are priorities. Previous work has demonstrated that apathy is one of the only behavioural symptoms that differentiates people with PD and intact cognition from those with mild cognitive impairment (MCI-PD). Other psychiatric symptoms emerge as dementia in PD develops.

Objective

We explored statistical models of longitudinal change to detect apathy as a behavioural predictor of cognitive decline in PD.

Methods

We followed 104 people with PD intermittently over 2 years, undertaking a variety of motor, behavioural and cognitive measures. We applied a linear mixed effects model to explore behavioural factors associated with cognitive change over time. Our approach goes beyond conventional modelling based on a random-intercept and slope approach, and can be used to examine the variability in measures within individuals over time.

Results

Global cognitive scores worsened during the two-year follow-up, whereas the longitudinal evolution of self-rated apathy scores and other behavioural measures was negligible. Level of apathy was negatively (− 0.598) correlated with level of cognitive impairment and participants with higher than average apathy scores at baseline also had poorer cognition. The model indicated that departure from the mean apathy score at any point in time was mirrored by a corresponding departure from average global cognitive score.

Conclusion

High levels of apathy are predictive of negative cognitive and behavioural outcomes over time, suggesting that apathy may be a behavioural indicator of early cognitive decline. This has clinical and prognostic implications.

Barriers and facilitators to diagnosing and managing apathy in Parkinson's disease: a qualitative study

BACKGROUND

Apathy is a prominent non-motor symptom in Parkinson's disease (PD). People with apathy show a lack of emotion, passion, and motivation. Between 17 and 70% of persons with PD have apathy; the extreme heterogeneity in these estimates is due to limited heterogeneous knowledge concerning how to diagnose PD. The lack of a widely utilized diagnostic process limits understandings on how to treat and manage apathy in PD. A scoping review of apathy in PD identified only one qualitative study investigating this symptom. It was our objective to assess perceived barriers and facilitators to diagnosing, treating, and managing apathy in PD, as described by key stakeholders.

METHODS

This research applied qualitative methodology, utilizing focus groups and interviews with health care practitioners (HCPs), persons with PD, and caregivers. Evidence gathered from a scoping review on apathy in PD informed discussions that took place with participants. Data collection and analysis was conducted using framework analysis, applying the Theoretical Domains Framework and Behaviour Change Wheel.

RESULTS

Eleven HCPs and five persons with PD/caregivers participated. Themes included interdisciplinary teams and communication with family to facilitate diagnosis and treatment, and the use of education and increased awareness of apathy to facilitate management. Themes surrounding barriers included lack of initiative and motivation to maintain treatment plans, and a lack of evidence for apathy specific interventions. While a key barrier identified was the lack of information HCPs have access to, persons with PD and caregivers would prefer to receive a diagnosis of apathy even with limited management methods. Thus, education and awareness were noted as two of the most important facilitators, overall.

CONCLUSION

These findings suggest that diagnosing, treating, and managing apathy in PD requires interdisciplinary teams, that include family and caregivers. We identified that where HCPs perceive lack of knowledge as a barrier to diagnosis, persons with PD and caregivers find being given a diagnosis facilitates understanding. These findings highlight the importance of qualitative research involving persons with PD and apathy, caregivers, and HCPs who aid in management of this symptom. Barriers reported suggest future research must aim to identify apathy specific treatments, both pharmacologic and non-pharmacologic.

DETERMINING FACTORS IN THE SITUATIONAL TRANSITION OF FAMILY MEMBERS WHO CARE OF ELDERLY PEOPLE WITH PARKINSON'S DISEASE

ABSTRACT Objective: to investigate the facilitator and inhibitory factors in the transition of elderly caregivers with Parkinson's disease. Method: a qualitative, exploratory and descriptive study, based on the family transition nursing theory developed with 20 elderly caregivers of elderly people with Parkinson 's disease, enrolled in the Associação Parkinson de Santa Catarina, from March to August 2015. To analyze and interpret the data, we used the thematic analysis of content proposed by Bardin, with the help of the ATLAS.ti software for data organization. Results: some factors were identified and considered as facilitators for the process of transition from the familiar to the exercise of the role of caregiver, such as: previous experiences as caregiver; spirituality and religiosity; family support network and health services. Other factors were identified as inhibiting factors for transition: emotional and physical health conditions; advanced age; personal life activities/commitments; family financial burden; and inadequate family support. It was observed that most family caregivers reported having previous experience in caring, having advanced age, and being able to care for the elderly with the disease. However, he considers his condition of emotional and physical health insufficient, resulting in overload. Lack of access to health services and family and financial support make it difficult to provide care. Conclusion: nurses should seek strategies to direct attention to facilitating factors in the family context in order to help the family to achieve well-being and healthy transition to the role of caregiver.

Use of the World Health Organization Quality of Life Assessment Short Version in Mild to Moderate Parkinson Disease

OBJECTIVE

To investigate the distribution, internal consistency reliability, and convergent and discriminant validity of the World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF) in persons with mild to moderate Parkinson disease (PD).

DESIGN

Cross-sectional.

SETTING

Movement disorders center.

PARTICIPANTS

Convenience sample of people with PD (n=96) recruited from a movement disorders center and controls (n=60) recruited from the community (N=156).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

WHOQOL-BREF.

RESULTS

The WHOQOL-BREF domain data were relatively normally distributed, and internal consistency reliability was acceptable (α=.65-.85). Participants with PD reported lower quality of life (QOL) than controls in all except the environment domain, and physical QOL was the most impaired domain in the PD group. Age, fatigue, and physical activity limitations predicted physical QOL; depression, fatigue, and apathy predicted psychological QOL; education, executive dysfunction, and apathy predicted social QOL; and age, education, depression, and apathy predicted environment QOL.

CONCLUSIONS

The WHOQOL-BREF is a suitable tool to assess QOL in patients with mild to moderate PD. It is relatively normally distributed and internally consistent; effectively discriminates between individuals with and without PD; and correlates with relevant demographic characteristics, PD-related impairments, and activity limitations.

Psychological Predictors of Anxiety and Depression in Parkinson's Disease: A Systematic Review

OBJECTIVES

Parkinson's disease (PD) is a neurodegenerative disorder, affecting the motor system with psychological difficulties also frequently reported. While explanations for psychological difficulties are historically situated within a biomedical framework, more recently the relevance of psychological determinants has become a research focus. This review therefore examines this relationship with the two most commonly reported psychological difficulties (anxiety and depression) in people with PD.

METHOD

Databases were systematically searched up to December 17, 2013, identifying 24 studies meeting inclusion criteria.

RESULTS

Significant predictors of heightened anxiety and depression included increased emotion-focused coping; less problem-focused coping; lower perceived control; more dominant beliefs about PD as part of a person's identity and influence on life; less social support and more avoidant personality types.

CONCLUSIONS

Relationships between some specific psychological predictors and depression and anxiety seem well supported. The complexity of relationships between these psychological determinants should be taken into consideration when delivering psychological interventions.
