Mindfulness based stress reduction in people with Parkinson's disease and their care partners

Effects of virtual reality mindfulness on cognition and well-being in ALS: A randomized trial protocol

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease primarily affecting motor neurons but also leading to significant non-motor symptoms, including cognitive impairments, anxiety, depression, and behavioral changes, which severely impact quality of life. While mindfulness-based interventions (MBIs) have shown promise in alleviating psychological distress, their accessibility is often limited due to patients' physical impairments. Virtual reality (VR) could enhance engagement and immersion, offering a novel, more inclusive therapeutic approach. This randomized controlled trial (RCT) aims to evaluate the efficacy of a VR-based MBI compared to traditional mindfulness for ALS patients. Forty-six participants will be randomly assigned to an eight-week mindfulness program delivered either via VR or in a conventional format. The primary outcome is quality of life, assessed using the ALS-Specific Quality of Life Scale (ALSSQOL-R). Secondary outcomes include cognitive function, anxiety, depression, behavioral changes, and mindfulness propensity, evaluated at baseline, post-intervention, and three-month follow-up. The study will also examine VR usability and potential accessibility challenges for ALS patients. By addressing a critical gap in non-pharmacological psychological care, this study will provide key insights into the feasibility and benefits of VR-based MBIs. If effective, VR mindfulness could offer an innovative, scalable solution to improve emotional well-being and quality of life in ALS, making psychological support more accessible for patients with severe physical limitations.

Parkinson's Disease and Caregiving Roles, Demands, and Support Needs and Experiences: A Scoping Review

Background and Objectives: A public health priority is the increasing number of persons with Parkinson's disease (PwP), and the need to provide them with support. We sought to synthesize the experiences of relatives or friends-family caregivers-who provide such support. Eligibility Criteria: This study was a scoping literature review modeled by the PRISMA guidelines. The articles for this review fit the following inclusion criteria: (1) studies including the perspective of caregivers of PwP, (2) studies conducted in the United States, and (3) studies conducted between January 2019 to January 2024. Sources of Evidence: Articles were identified by searching the PubMed, EBSCO, and Ovid databases between January 2019 and January 2024. The search terms included the following: (Parkinson's disease) AND (caregiver OR caregiving OR carer). Results: A total of 31 articles were included. Most of the included articles are descriptive (n = 26), including quantitative (n = 17), qualitative (n = 7), and mixed-methods studies (n = 2). Gender, race, and ethnicity were not consistently reported. Findings across studies demonstrated common roles of caregiving (e.g., assistance with personal care), extensive physical and mental health strains, social isolation, and work and financial strain. Benefit-finding was also evident among caregivers including a goal of securing the PwP dignity and comfort as the disease progressed. The studies of this review provide perspectives on benefits and challenges of caregiving in this context and caregiver resources. Conclusions: Future studies need to improve racial and gender-related diversity and address caregiver strain and health.

Mindfulness in Parkinson's disease: A French national survey and a pilot intervention feasibility trial using the MBSR program (M-Park)

BACKGROUND

Non-pharmacological complementary interventions, particularly mind-body practices, are of growing importance in the management of Parkinson's disease (PD). Among these, mindfulness meditation seems particularly effective, especially on anxiety and depression symptoms. However, current knowledge on mindfulness standardized programs in PD is still limited, particularly in France. Aiming at improving this knowledge we designed the M-PARK study in two phases. Phase 1 consisted in a French national survey to explore expectations, needs and initiatives for mindfulness meditation for PD patients. Phase 2 was a clinical trial with objectives to assess feasibility, acceptability and effects of a mindfulness (MBSR) program proposed to PD patients.

METHODS

In phase 1, online questionnaires were addressed to members of a French PD patient's association (France Parkinson) and French MBSR qualified instructors. In Phase 2, a clinical trial involving 30 PD patients consisted of a standard MBSR program with two additional evaluation visits one month before and after the program. Data collection included a global clinical evaluation, assessment of depression and anxiety symptoms, sleep, pain and quality of life and a face-to-face interview for qualitative assessment of the acceptability and lived experience during the program. Three MBSR programs were proposed to three groups of ten patients: two were online due to the pandemic situation, one proposed to patients with no or minor fluctuations (group 1) and one for patients with slight to moderate fluctuations (group 2), and the last one face-to-face for patients with no or minor fluctuations (group 3).

RESULTS

French survey: 209 responses were collected for the questionnaire sent to the members of the association France Parkinson; and 68 for the questionnaire sent to the instructors. Two-thirds of patients surveyed had heard of mindfulness meditation (66%), but were unaware of what this approach really consisted and how it could really help them. Few instructors (29%) had had to deal with patients with PD in their current practice. Yet 90% of patients surveyed indicated they were in favor of introducing this type of approach into their care.

CLINICAL TRIAL

The results indicated that the program is feasible and acceptable both online and face-to-face for patients with PD. Among the 30 patients enrolled, 25 completed the program. No unwanted effects related to mindfulness meditation practice were observed. The results showed a statistically significant reduction in anxiety symptoms, depressive symptoms, and improvement in quality of life. Furthermore, no statistically significant change was measured for pain or sleep quality. There was no striking difference in results observed between the patient groups. For the qualitative analysis, major themes highlighted were in relation with: (i) the lived experience during program; (ii) changes in the daily life; and (iii) disease-related changes. A large majority of patients who completed the program (24/25) described their participation as positive or very positive. They reported better management of stress and emotions, as well as greater autonomy in implementing new behavioral strategies, particularly in terms of self-care, acceptance, and de-identification from the disease.

CONCLUSION

Despite high expectations, PD patients are poorly informed about available mindfulness programs. This study however shows that these programs, whether offered online or face-to-face, are particularly beneficial, especially for anxiety and depressive symptoms, at least in mild-to-moderate stages of the disease.

The Feasibility and Efficacy of a Virtual Reality Tandem Cycling Program for Persons with Parkinson's Disease and Their Care Partners

INTRODUCTION

Persons with Parkinson's disease (PwPD) suffer from motor and non-motor symptoms which significantly affect their quality of life (QoL), and the QoL of their care partners (CP). Tandem cycling reduces PwPD motor symptoms; however, no studies have examined other benefits or included PwPD CP. We conducted an 8-week community virtual reality (VR) tandem cycling intervention to assess the feasibility and efficacy for PwPD and their CP (i.e., PD dyads). We hypothesized that dyadic tandem cycling would improve (1) PwPD motor and non-motor symptoms and (2) dimensions of PD dyads' QoL and physiologic health.

METHODS

Ten PD dyads were recruited to complete 8 weeks of progressive intensity, bi-weekly tandem cycling. At pre- and post-testing, PwPD were assessed using the Movement Disorder Society-Unified Parkinson's Disease Rating Scale-III (MDS-UPDRS-III), functional gait assessment (FGA), and 10-m gait speed test. PD dyads also completed emotional and cognitive status questionnaires [e.g., Geriatric Depression Scale-Short Form (GDS-SF)], and wore BodyGuard 2 heart rate (HR) monitors for 48 h to assess surrogate measures of heart rate variability. Statistical analyses were conducted using Student's t tests with significance set at p ≤ 0.05.

RESULTS

Eight PD dyads and one PwPD completed the intervention. Retention of PwPD (90%) and CP (80%) was adequate, and PD dyad adherence ranged from 91.67 to 97.91%. PwPD demonstrated significant clinical improvements in MDS-UPDRS-III scores (- 7.38, p < 0.01), FGA scores (+ 3.50, p < 0.01), and 10-m gait speed times (+ 0.27 m/s, p < 0.01), in addition to significant self-reported improvements in mobility (- 13.61, p = 0.02), fatigue (- 5.99, p = 0.02), and social participation (+ 4.69, p < 0.01). CP depressive symptoms significantly decreased (- 0.88, p = 0.02), and PD dyads shared a significant increase in root mean square of the successive differences (RMSSD; p = 0.04).

CONCLUSION

Our pilot study demonstrated feasibility and multiple areas of efficacy supporting further investigation of community VR tandem cycling as a therapeutic intervention for PD dyads.

Risk factors and intervention of caregiver burden in Parkinson's disease: a systematic review and meta-analysis

PURPOSE

This study summarized characteristics and risk factors of caregiver burden in PD patients and used meta-analysis to verify the effectiveness of the intervention on caregiver burden.

METHODS

Systematic review and meta-analysis were conducted.

RESULTS

Forty-nine articles that involved 5387 caregivers of patients with PD were included in this study. Results of systematic review indicated that Zarit burden Inventory (ZBI) was the most used scale to measure the caregiver burden. All scales revealed caregivers of PD patients had mild to moderate caregiver burden. For the PD patients with longer disease duration, severer disease severity, more negative emotion and cognition impairment, their caregivers intended to have higher caregiver burden. The caregiver with negative emotion and who spent more time on caregiving indicated higher caregiver burden than the others. The caregiver burden was not improved after deep brain stimulation (DBS). Meta-analysis showed that cognitive behavior therapy and palliative care had no significant effect to reduce caregiver burden in PD patients' caregiver.

CONCLUSION

Caregivers of PD patients experienced mild to moderate caregiver burden. Demographic factor, diseased-related factor and negative emotional factor were the risk factors of caregiver burden. Health education and care support for long-term management after DBS surgery should be provided for patients and caregivers to decrease caregiver burden.

Caregiver Burden in Parkinson Disease: A Scoping Review of the Literature from 2017-2022

Caregiver burden is a term that refers to the adverse effect of caregiving on the physical, emotional, social, spiritual, and financial well-being of the caregiver. Caregiver burden is associated with providing care to an individual with a chronic illness or disability, and the unique symptoms of Parkinson disease (PD) can amplify a patient's needs and reliance on others, leading to adverse outcomes for patients and their caregivers. In this scoping review of the literature from January 2017 through April 2022 that included 114 studies, we provide an updated, evidence-based summary of patient and caregiver-related factors that contribute to caregiver burden in PD. We also describe the impact of caregiver stress and burden on caregivers based on qualitative research studies and review recent interventions to mitigate burden. By providing clinical updates for practitioners, this review is designed to improve recognition of caregiver burden in the post-pandemic era and foster the development of targeted interventions to reduce caregiver burden in PD.

The Effects of Mindfulness-Based Interventions in People with Parkinson's Disease: A Systematic Review and Meta-Analysis

OBJECTIVES

To examine the effectiveness of mindfulness-based interventions (MBIs) on psychological symptoms, motor symptoms, and quality of life in patients with Parkinson's disease (PD).

METHODS

Published studies in Chinese and English languages, conducted from inception to March 2023, were identified by searching PubMed, Web of Science, Cochrane Library, CINAHL, PsycINFO, and two Chinese electronic databases. The systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines.

RESULTS

Twelve studies were selected for quantitative syntheses. The impact of MBIs on reducing depression and anxiety, and improving mindfulness and quality of life in PD patients was statistically significant compared to the control group. However, no statistically significant effect on motor symptoms was observed. Subgroup analysis indicated that participants from Asia, those who received face-to-face sessions, and those whose sessions lasted 1.5 hours showed a more positive effect than other subgroups.

CONCLUSIONS

Patients with PD may benefit from MBIs to improve psychological symptoms and quality of life. MBIs represent a pivotal non-pharmacological therapeutic approach in clinical practice.

CLINICAL IMPLICATIONS

MBIs confer positive improvements in psychological well-being and quality of life in PD patients. However, it remains challenging to conclusively determine their efficacy in addressing motor symptoms.

Alleviating Stress in Parkinson's Disease: Symptomatic Treatment, Disease Modification, or Both?

Psychological stress, a state of mental strain caused by mentally or physically threatening situations, plays a significant role in Parkinson's disease (PD). Motor symptoms worsen during acute stress and common non-motor symptoms in PD, such as anxiety and depression, are linked to chronic stress. Although evidence in humans is lacking, animal models of PD suggest that chronic stress can accelerate dopaminergic cell death. This suggests that stress-reducing interventions have not only symptomatic, but perhaps also disease-modifying effects. Our objective was to identify the most promising strategies for stress-reduction in PD and to analyze their potential value for disease-modification. An unstructured literature search was performed, primarily focusing on papers published between 2020-2023. Several large clinical trials have tested the efficacy of aerobic exercise and mindfulness-based interventions on PD symptoms. The evidence is promising, but not definitive yet: some exercise trials found a reduction in stress-related symptoms, whereas others did not or did not report it. In the majority of trials, biological measures of stress and of disease progression are missing. Furthermore, follow-up periods were generally too short to measure disease-modifying effects. Hence, mechanisms underlying the intervention effects remain largely unclear. These effects may consist of attenuating progressive neurodegeneration (measured with MRI-markers of substantia nigra integrity or cortical thickness), or a strengthening of compensatory cerebral mechanisms (measured with functional neuroimaging), or both. Lifestyle interventions are effective for alleviating stress-related symptoms in PD. They hold potential for exerting disease-modifying effects, but new evidence in humans is necessary to fulfill that promise.

A Pilot Study of Telehealth Mindfulness-Based Cognitive Therapy for Depression in Parkinson's Disease

Introduction: Parkinson's disease (PD) is characterized by high-rates of depression with limited evidence-based treatment options to improve mood. Objective: To expand therapeutic options, we evaluated the feasibility and effect of a telehealth mindfulness-based cognitive therapy intervention adapted for PD (MBCT-PD) in a sample of participants with DSM-5 depressive disorders. Methods: Fifteen participants with PD and clinically-significant depression completed 9 sessions of MBCT-PD. Depression, anxiety, and quality of life were evaluated at baseline, endpoint, and 1-month follow-up. Results: Telehealth MBCT-PD was feasible and beneficial. Completion rates exceeded 85% and treatment satisfaction rates were high. Notable improvements were observed for depression, anxiety, and quality of life over the course of the trial. Conclusion: Telehealth MBCT-PD shows promise and warrants further evaluation via randomized clinical trial with more diverse participants. Such research holds the potential to expand the range of therapeutic options for depression in PD, thereby setting the stage for personalized care.

A randomized clinical trial of mindfulness meditation versus exercise in Parkinson's disease during social unrest

Clinical practice guidelines support resilience training and exercise for patients with Parkinson's disease (PD). This assessor-blinded, randomized clinical trial aimed to compare the effects of a modified mindfulness meditation program versus stretching and resistance training exercise (SRTE) in patients with mild-to-moderate PD. A total of 126 potential participants were enrolled via convenience sampling, of which 68 eligible participants were randomized 1:1 to receive eight weekly 90-min sessions of mindfulness meditation or SRTE. Compared to the SRTE group, generalized estimating equation analyses revealed that the mindfulness group had significantly better improvement in outcomes, particularly for improving depressive symptoms (d, -1.66; 95% CI, -3.31 to -0.02) at week 8 and maintaining emotional non-reactivity at week 20 (d, 2.08; 95% CI, 0.59 to 3.56). Both groups demonstrated significant immediate, small-moderate effects on cognition (effect size [d] = 0.36-0.37, p = 0.006-0.011). Compared with the SRTE, mindfulness meditation appeared to be a feasible and promising strategy for managing depressive symptoms and maintaining emotional stability, with comparable benefits on cognitive performance. To combat the psychospiritual and cognitive sequelae of social unrest and COVID-19 pandemic, the integration of mindfulness training into motor-oriented PD rehabilitation protocols is recommended to strengthen the resilience and minimize the psycho-cognitive comorbidities among patients with mild-to-moderate PD.Trial Registration: HKU Clinical Trials Registry identifier: HKUCTR-2681.
