Mindfulness-based stress reduction for people with multiple sclerosis - a feasibility randomised controlled trial

Cognitive impairment in multiple sclerosis: from phenomenology to neurobiological mechanisms

Multiple sclerosis (MS) is an autoimmune-mediated disease of the central nervous system characterized by inflammation, demyelination and chronic progressive neurodegeneration. Among its broad and unpredictable range of clinical symptoms, cognitive impairment (CI) is a common and disabling feature greatly affecting the patients' quality of life. Its prevalence is 20% up to 88% with a wide variety depending on the phenotype of MS, with highest frequency and severity in primary progressive MS. Involving different cognitive domains, CI is often associated with depression and other neuropsychiatric symptoms, but usually not correlated with motor and other deficits, suggesting different pathophysiological mechanisms. While no specific neuropathological data for CI in MS are available, modern research has provided evidence that it arises from the disease-specific brain alterations. Multimodal neuroimaging, besides structural changes of cortical and deep subcortical gray and white matter, exhibited dysfunction of fronto-parietal, thalamo-hippocampal, default mode and cognition-related networks, disruption of inter-network connections and involvement of the γ-aminobutyric acid (GABA) system. This provided a conceptual framework to explain how aberrant pathophysiological processes, including oxidative stress, mitochondrial dysfunction, autoimmune reactions and disruption of essential signaling pathways predict/cause specific disorders of cognition. CI in MS is related to multi-regional patterns of cerebral disturbances, although its complex pathogenic mechanisms await further elucidation. This article, based on systematic analysis of PubMed, Google Scholar and Cochrane Library, reviews current epidemiological, clinical, neuroimaging and pathogenetic evidence that could aid early identification of CI in MS and inform about new therapeutic targets and strategies.

Behavioral Interventions to Improve Sleep Outcomes in Individuals With Multiple Sclerosis: A Systematic Review

BACKGROUND

Sleep disturbances are common in individuals with multiple sclerosis. The objective of this systematic review was to determine effective behavioral interventions to improve their sleep.

METHODS

Literature searches were performed in December 2021 in Ovid MEDLINE, Elsevier Embase, and Web of Science, along with hand searching for grey literature and cited references. Four reviewers independently reviewed titles and abstracts (2 reviewers for each article; n = 830) and the full-text articles (n = 81). Consensus for inclusion was achieved by a fifth reviewer. Thirty-seven articles were eligible for inclusion. Four reviewers extracted relevant data from each study (2 reviewers for each article) using a standard data extraction table. Consensus was achieved for completeness and accuracy of the data extraction table by a fifth reviewer. The same 4 reviewers conducted a quality appraisal of each article to assess the risk of bias and quality of the articles, and consensus was achieved by a fifth reviewer as needed. Descriptive data were used for types of interventions, sleep outcomes, results, and key components across interventions.

RESULTS

Overall, the cognitive behavioral therapy for insomnia, cognitive behavioral therapy/psychotherapy, and education/self-management support interventions reported positive improvements in sleep outcomes. Quality appraisal scores ranged from low to high, indicating potential for bias.

CONCLUSIONS

Variability in the intervention type, intervention dose, outcomes used, training/expertise of interventionist, specific sample, and study quality made it difficult to compare and synthesize results. Further research is necessary to demonstrate the efficacy of most of the interventions.

The Effect of Mindset and Breathing Exercises on Physical and Mental Health in Persons with Spinal Cord Injury-A Pilot Feasibility Study

This study investigated the feasibility and efficacy of mindset and breathing exercises (Wim Hof Method (WHM)) on physical and mental health in persons with spinal cord injury (SCI). Ten individuals with SCI participated in this pilot study. These ten participants followed a 4-week WHM intervention, with one weekly group session in the rehabilitation center and daily practice at home using the WHM app. An in-person exit-interview was conducted post-intervention to collect qualitative information on participants' experiences, regarding the feasibility and effects of the intervention. Furthermore, tests and questionnaires were administered pre- and post-intervention to assess physical and mental health outcomes. Adherence to the weekly in-person meetings was excellent and no adverse events occurred. Physical and mental health outcomes in this small sample size showed some pre-post differences. This pilot feasibility study provides preliminary evidence supporting the feasibility and efficacy of the WHM, including mindset and breathing exercises, on physical and mental health of people with SCI. These results warrant a randomized-controlled trial, including cold exposure, of this novel intervention in people with SCI.

The HEADS: UP Development Study: Working with Key Stakeholders to Adapt a Mindfulness-Based Stress Reduction Course for People with Anxiety and Depression after Stroke

BACKGROUND

Following stroke, rates of mood disorder are and remain high at five years (anxiety 34.4%; depression 23%). Structured mindfulness-based stress reduction (MBSR) courses are effective in a range of health conditions, but stroke survivors find adherence challenging. We aimed to adapt a standard MBSR course specifically for people affected by stroke.

METHODS

We recruited stroke survivors and family members with symptoms of anxiety and/or depression to take part in a co-development study comprising two rounds of MBSR 'taster' sessions, followed by focus groups in which views were sought on the practices sampled. Data were collected in October 2017 and May 2018 and were analysed using framework analysis, informed adaptations to mindfulness materials and delivery.

RESULTS

Twenty-eight stroke survivors and seven family members participated. Nineteen (76%) stroke survivors had anxiety; 15 (60%) had depression. Five (71.4%) family members reported anxiety; n = 4 (57.1%) depression. Thirty participants attended the first round of taster sessions and focus groups; twenty (66%) the second and three (10%) were unable to attend either round. Framework analysis informed adaptations to course delivery, practices, and materials, ultimately resulting in a stroke-specific MBSR course, HEADS: UP (Helping Ease Anxiety and Depression after Stroke).

CONCLUSIONS

HEADS: UP may provide a feasible, appropriate, and meaningful self-management intervention to help alleviate symptoms of mood disorder.

Conceptualization, use, and outcomes associated with compassion in the care of people with multiple sclerosis: a scoping review

OBJECTIVE

Compassion is widely regarded as an important component of high-quality healthcare. However, its conceptualization, use, and associated outcomes in the care of people with multiple sclerosis (PwMS) have not been synthesized. The aim of this review is to scope the peer reviewed academic literature on the conceptualization, use, and outcomes associated with compassion in the care of PwMS.

METHODS

Studies were eligible for inclusion if reporting primary research data from quantitative, qualitative, or mixed-methods studies on the conceptualization, use, and outcomes associated with compassion in the care of PwMS. Relevant studies were identified through searching five electronic databases (CINAHL, Cochrane Library, EMBASE, MEDLINE, and PsycINFO) in January 2022. We followed the guidance outlined in the Joanna Briggs Institute (JBI) manual for evidence synthesis, and also referred to the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews Checklist (PRISMA-ScR). Simple descriptive methods were used to chart quantitative findings, and a descriptive approach with basic content analysis was employed to describe qualitative findings.

RESULTS

Fifteen studies were included (participant n = 1722): eight quantitative, six mixed-methods, one exclusively qualitative. Synthesized qualitative data revealed that PwMS conceptualize compassion as involving self-kindness, agency, and acceptance. PwMS report using self-compassion in response to unpleasant sensations and experiences. Quantitative findings suggest that compassion may mediate benefit finding, reduced distress, and improved quality of life (QoL) in PwMS, that those with the condition may become more compassionate through time, and that self-compassion specifically can be increased through training in mindfulness. In this context, greater self-compassion in PwMS correlates with less depression and fatigue, better resilience and QoL. Among studies, self-compassion was the most common outcome measure for PwMS.

CONCLUSIONS

A nascent literature exists on the conceptualization, use, and outcomes associated with compassion in the care of PwMS. Further research is required to better understand what compassion means to PwMS and those caring for them. However, self-compassion can be cultivated among PwMS and may be helpful for managing unpleasant somatic symptoms and in benefit finding. Impact on other health outcomes is less clear. The use of compassion by health care providers in the care of PwMS is unstudied.

A systematic review and meta-analysis exploring the efficacy of mindfulness-based interventions on quality of life in people with multiple sclerosis

BACKGROUND

Quality of life (QoL) is commonly impaired among people with multiple sclerosis (PwMS). The aim of this study was to evaluate via meta-analysis the efficacy of Mindfulness-based interventions (MBIs) for improving QoL in PwMS.

METHODS

Eligible randomized controlled trials (RCTs) were identified via searching six major electronic databases (MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, AMED, and PsycINFO) in April 2022. The primary outcome was QoL. Study quality was determined using the Cochrane Collaboration risk of bias tool. Meta-analysis using a random effects model was undertaken. Effect sizes are reported as Standardized Mean Difference (SMD). Prospero ID: 139835.

RESULTS

From a total of 1312 individual studies, 14 RCTs were eligible for inclusion in the meta-analysis, total participant n = 937. Most studies included PwMS who remained ambulatory. Cognitively impaired PwMS were largely excluded. Comorbidities were inconsistently reported. Most MBIs were delivered face-to face in group format, but five were online. Eight studies (n = 8) measured MS-specific QoL. In meta-analysis, overall effect size (SMD) for any QoL measure (n = 14) was 0.40 (0.18-0.61), p = 0.0003, I² = 52%. SMD for MS-specific QoL measures (n = 8) was 0.39 (0.21-0.57), p < 0.0001, I² = 0%. MBI effect was largest on subscale measures of mental QoL (n = 8), SMD 0.70 (0.33-1.06), p = 0.0002, I² = 63%. Adverse events were infrequently reported.

CONCLUSIONS

MBIs effectively improve QoL in PwMS. The greatest benefits are on mental health-related QoL. However, more research is needed to characterize optimal formatting, mechanisms of action, and effects in PwMS with more diverse social, educational, and clinical backgrounds.

Feasibility, Acceptability, and Efficacy of Mindfulness Training in People With Upper Motor Neuron Disorders: A Systematic Review

OBJECTIVES

This systematic review aims to gain a comprehensive understanding of the feasibility, acceptability, and efficacy of mindfulness-based interventions (MBIs) on depression, anxiety, fatigue, and health-related quality of life among individuals with upper motor neuron disorders (UMNDs).

DATA SOURCES

PubMed, PsycINFO, Excerpta Medica Database, and Cumulative Index to Nursing and Allied Health Literature were searched for relevant studies published between January 2001 and June 2021.

STUDY SELECTION

Clinical trials published in English evaluating MBIs in adults with the 4 most common UMNDs (multiple sclerosis, brain injury including stroke, spinal cord injury, amyotrophic lateral sclerosis) were included.

DATA EXTRACTION

Two reviewers independently performed the risk of bias assessment using standardized tools and extracted desired data electronically.

DATA SYNTHESIS

A total of 44 studies were included: 26 randomized controlled trials, 10 nonrandomized controlled trials, and 8 pre-post intervention studies. The average ± SD duration of MBIs was 8±2 weeks. On average, 85%±14% of participants completed the MBI, and the retention rate at follow-up was 80%±16%. Only 14% of the studies delivered MBIs virtually, and feasibility metrics were similar to in-person studies. Among studies reporting acceptability data, most participants reported satisfaction with the MBI. Randomized controlled trials that evaluated the effects of MBI on depression, anxiety, fatigue, and quality of life revealed greater relative improvement in these outcomes among MBI participants compared with controls, with differences greater when compared with passive control than active control participants. None of the studies included in this review studied dose response.

CONCLUSIONS

Based on current data, MBIs are feasible and offer a promising approach to address the biopsychosocial needs of individuals with UMNDs. MBIs are associated with a high acceptance rate among participants, with notable improvements in depression, anxiety, fatigue, and quality of life post intervention. Future studies are needed to evaluate alternate models of delivery of MBIs and the dose-response relationship.

Effectiveness of non-pharmacological rehabilitation interventions in pain management in patients with multiple sclerosis: Systematic review and meta-analysis

BACKGROUND

Multiple sclerosis (MS) is a progressive inflammatory and autoimmune neurological disease caused by inflammation and demyelination of the central nervous system. Pain is a typical symptom of central nervous system demyelination, affecting 63% of adults with MS. Recently, the role of non-pharmacological pain management in patients is growing because the non-pharmacological interventions are considered safe, affordable, easy, and accessible. However, to date, no systematic reviews or meta-analyses have comprehensively examined the therapeutic effects of the variety of non-pharmacological therapeutic interventions in the management of pain in patients with MS.

OBJECTIVE

The study aimed to conduct a systematic review with meta-analysis to assess the effectiveness of the non-pharmacological rehabilitation interventions in pain management in patients with MS.

METHODS

A comprehensive search using PubMed, Cochrane, and Science Direct databases was performed and included all randomized controlled trials, randomized cross-over trials, and quasi-experimental trials assessing the effect of non-pharmacological interventions for managing pain in patients with MS. This study was conducted according to PRISMA guidelines of a systematic review and pair-wise meta-analysis. Meta-analyses were performed by calculating the standardized mean difference at a 95% confidence interval using Review Manager software.

RESULTS

Twenty-nine papers were included in the systematic review, and only 22 of them were included in the meta-analysis. The pooled analysis showed a significant effect of neuromodulation and transcranial direct current stimulation on pain intensity reduction in patients with MS (SMD -0.51, 95% CI -0.51 to -0.09, P = 0.02), (SMD -0.67, 95% CI -1.18 to -0.16 P = 0.01), respectively. The analysis showed significant improvement in pain intensity in patient with MS after mind-body therapies (SMD -0.45, 95% CI -0.82 to -0.7, P = 0.02), mindfulness (SMD -0.55, 95% CI -0.96 to -0.14, P = 0.009), hypnosis (SMD -0.88, 95% CI -1.30 to -0.46, P = 0.0001), trigger point therapies (SMD -0.83, 95% CI -1.65 to -0.01, P = 0.05) and cognitive behavioral therapy (SMD -0.64, 95% CI -1.18 to -0.11, P = 0.02). However, there is no significant effect of relaxation therapy on pain reduction in patients with MS (SMD -0.82, 95% CI -1.94 to 0.31, P = 0.15).

CONCLUSIONS

The results indicated that the majority of the non-pharmacological rehabilitation interventions showed potential therapeutic effects in reducing pain intensity in patients with MS.

A Hybrid Approach for MS Diagnosis Through Nonlinear EEG Descriptors and Metaheuristic Optimized Classification Learning

Multiple sclerosis (MS), a disease of the central nervous system, affects the white matter of the brain. Neurologists interpret magnetic resonance images that are often complicated, time-consuming, and contradictory. Using EEG signals, this disease can be analyzed and diagnosed more accurately. However, it is imperative that MS be diagnosed by specialists using assistive technology. Until now, a few methods have been proposed in this field that are sometimes associated with different challenges in analysis. This paper presents a hybrid approach to MS diagnosis in order to decrease classification error rates. Using the proposed method, EEG descriptors in both the time and frequency domains are analyzed. After the feature extraction stage, a modified version of the ant colony optimization method (m-ACO) was used to select the appropriate subset of features. Then, the support vector machine is used to determine whether the disease exists. A metaheuristic algorithm adjusts the support vector machine's parameters to withstand overfitting challenges. Despite a limited number of input channels, significant classification accuracy has been achieved using wavelet analysis techniques, dividing all five subbands of EEG signals, signal windowing, and extracting efficient features from the data. Additionally, alpha, beta, and gamma bands of the signal are important, and the accuracy, sensitivity, and specificity levels are higher than 98.5%. Compared to similar MS diagnostic methods, the proposed method achieved significantly higher diagnostic accuracy. Application and implementation of this method can be effective in treating neurological diseases, including multiple sclerosis.

Third wave cognitive behavioural therapies for people with multiple sclerosis: a scoping review

PURPOSE

Multiple sclerosis (MS) is a chronic condition linked to a wide range of psychological difficulties. While traditional cognitive behavioural therapy has been studied extensively with people with MS, much less is known about more recent "third wave" approaches.

METHODS

A scoping review was carried out by performing a systematic search across MEDLINE Complete, PsycINFO, CINAHL, Academic Search Ultimate, and Cochrane Library up to January 2022.

RESULTS

From an initial return of 8306 citations, 35 studies were included, 20 of which were randomised controlled trials (RCTs). These showed that four third wave approaches have been investigated with people with MS to date: acceptance and commitment therapy (ACT), dialectical behaviour therapy (DBT), mindfulness-based stress reduction (MBSR), and mindfulness-based cognitive therapy (MBCT). MBSR and MBCT may be helpful to address a range of psychological difficulties up to three months post-intervention. However, MS-specific adaptations may be required, and more evidence is needed on longer-term effectiveness. Limited evidence is also available for DBT and ACT, but additional research is warranted before any recommendation can be made.

CONCLUSIONS

As third wave approaches keep being refined, further more rigorous investigations are needed to implement them to the benefit of people with MS. Implications for RehabilitationMultiple sclerosis is linked to a wide range of psychological difficulties in adults.Little is currently known on third wave psychotherapies for people with MS.Mindfulness-based stress reduction and mindfulness-based cognitive therapy may be helpful to address a wide range of difficulties in MS.Specific adaptations may be needed to deliver suitable therapies to people with MS.Additional research is warranted to build on preliminary findings for DBT and ACT.

Mindfulness-integrated cognitive behavioral therapy: Is it effective on stress coping strategies in women with multiple sclerosis?

BACKGROUND

Patients with chronic diseases such as multiple sclerosis (MS) suffer more from psychiatric consequences than others, and their quality of life may be drastically affected, causing syndromes like depression and anxiety. Mindfulness-integrated cognitive behavioral therapy (Mi-CBT) seems to improve stress coping strategies in chronically ill patients, but its effectiveness has been little studied in MS. So, in this study, we aimed to assess its effectiveness on stress coping strategies in women suffering from MS in Mazandaran province, Iran.

METHODS

In this semi-experimental study, we selected 40 women with MS who had been referred to a neurologist in Mazandaran province, Iran during the year 2016 by convenient sampling and randomly assigned to the Mi-CBT and control group with a one-to-one ratio. Patients in the intervention group were under treatment for eight 120-minutes session, while the control group only stayed on the waiting list. After obtaining the ethics committee's approval (IR.IAU.CHALUS.REC.1397.018) and patient's informed consent, both groups underwent a pre-test assessment with a stress status questionnaire developed by Endler and Parker in 1988. The same assessment was done for both groups two times more, one after compilation of all sessions, and one 45 days later. Repeated measures analysis of variance was done using SPSS Version 24 software.

RESULTS

There was a difference between intervention and the control group for avoidance-oriented, and problem-oriented stress coping strategies (p<0.01), but there was not a significant difference for emotion-oriented strategy between groups (P=0.22).

CONCLUSION

MiCBT is effective in improving stress coping strategies in women with MS, and overall mental health.

Psychological well-being in people with multiple sclerosis: a descriptive review of the effects obtained with mindfulness interventions

Multiple sclerosis is a neuroinflammatory and neurodegenerative disease causing several psychosocial problems that significantly impairs quality of life. The most common physical and mental symptoms are anxiety, depression, stress, fatigue, and pain. Several studies investigated the effectiveness of non-pharmacological approaches in improving psychological well-being. This review focused on the impact of mindfulness interventions in patients with multiple sclerosis to reduce psychopathological symptoms and improve well-being. We searched on PubMed database and screening references of included studies and review articles for additional citations. From initial 107 studies, only 8 met search criteria. Our studies showed the efficacy of mindfulness treatment with a reduction in depressive symptoms, a better quality of life (both mental and physical), and a decreased level of fatigue. Findings demonstrated that mindfulness is useful for the improvement of psychological symptoms and pain management and this improvement has also been shown to have a positive impact on the quality of life and coping and adaptation strategies. However, according to the poor available clinics evidence, on cannot conclude that mindfulness interventions are superior to other active interventions in the treatment of psychological symptoms of SM.

Mindfulness training during brief periods of hospitalization in multiple sclerosis (MS): beneficial alterations in fatigue and the mediating role of depression

OBJECTIVES

Persons with MS (PwMS) are frequently affected by fatigue and depression. Mindfulness-based interventions may reduce these symptoms in PwMS and consequently their application has been extended to various settings. Only few efforts have been made to explore effects of short-term mindfulness training during brief periods of hospitalization. In the current study, the feasibility and potential effects of short-term mindfulness training on depression, fatigue, rumination and cognition were explored in PwMS in an acute-care hospital setting. Based on previous work, it was further examined whether the relation between trait mindfulness and fatigue prior to and following the intervention was mediated by depression and whether a mediation effect was also observable throughout the intervention.

METHODS

A short-term mindfulness training protocol was developed, tailored to the requirements of the acute-care setting. Subsequently, 30 PwMS were recruited sequentially and received mindfulness training during the routine clinical process (median duration in hospital: eight days, number of sessions: four). Participants completed relevant self-report measures (depression, fatigue, rumination) and a neuropsychological assessment before and after training.

RESULTS

Participants reported significantly increased trait mindfulness and decreased depression and fatigue following the intervention. Respective change scores were highly correlated so that increased trait mindfulness was associated with decreased symptoms. In the rumination domain, patients reported a tendency for an increased adaptive ability to engage in distractive behavior during arising negative mood. Other measures of trait rumination and cognition remained relatively stable. Results of the mediation analyses indicated that depression mediated the negative relationship between trait mindfulness and fatigue symptoms at pre and post assessments. With regards to the change scores, an association between mindfulness and cognitive fatigue ceased to be significant when depression was controlled, albeit in this case, the mediation effect did not reach significance.

CONCLUSION

Results of the current study indicate that short-term mindfulness training during brief periods of hospitalization may be beneficial for PwMS. They further complement previous work by identifying depression as a potential mediator of the antagonistic relationship between mindfulness and fatigue. Based on the current exploratory study, future trials are warranted to address this mechanism of mindfulness training in more detail.

Which exercise and behavioural interventions show most promise for treating fatigue in multiple sclerosis? A network meta-analysis

BACKGROUND

Fatigue is a common, debilitating symptom of multiple sclerosis (MS) without a current standardised treatment.

OBJECTIVE

The aim of this systematic review with network meta-analyses was to estimate the relative effectiveness of both fatigue-targeted and non-targeted exercise, behavioural and combined (behavioural and exercise) interventions.

METHODS

Nine electronic databases up to August 2018 were searched, and 113 trials (n = 6909) were included: 34 were fatigue-targeted and 79 non-fatigue-targeted trials. Intervention characteristics were extracted using the Template for Intervention Description and Replication guidelines. Certainty of evidence was assessed using GRADE.

RESULTS

Pairwise meta-analyses showed that exercise interventions demonstrated moderate to large effects across subtypes regardless of treatment target, with the largest effect for balance exercise (SMD = 0.84). Cognitive behavioural therapies (CBTs) showed moderate to large effects (SMD = 0.60), with fatigue-targeted treatments showing larger effects than those targeting distress. Network meta-analysis showed that balance exercise performed significantly better compared to other exercise and behavioural intervention subtypes, except CBT. CBT was estimated to be superior to energy conservation and other behavioural interventions. Combined exercise also had a moderate to large effect.

CONCLUSION

Treatment recommendations for balance and combined exercise are tentative as the certainty of the evidence was moderate. The certainty of the evidence for CBT was high.

Mindfulness-based interventions for people with multiple sclerosis: a systematic review and meta-aggregation of qualitative research studies

PURPOSE

Mindfulness-based interventions (MBIs) are effective treatments for stress, anxiety, and depression in PwMS. However, low adherence and high attrition may limit effectiveness. Qualitative research can provide important insights into MBI acceptability, accessibility, and implementation. This systematic review and meta-aggregation evaluated qualitative research findings on the use of MBIs for PwMS.

METHODS

Systematic searches were undertaken in six major electronic databases. Studies using qualitative or mixed methods were included. Two reviewers screened, data extracted, and critically appraised studies. Meta-aggregation was performed following the Joanna Briggs Institute approach, extracting findings, developing categories, and synthesizing findings.

RESULTS

Six eligible papers, including 136 PwMS were included in meta-aggregation. 136 findings were extracted, grouped into 17 categories, with four synthesized findings: (1) "accessing mindfulness," (2) "a sense of belonging," (3) "experiencing mindfulness," and (4) "making mindfulness more relevant and sustainable for PwMS."

CONCLUSIONS

MBIs for PwMS need to take into consideration disability which can limit accessibility. Online MBIs (synchronous and asynchronous) appear acceptable alternatives to traditional face-to-face courses. However, PwMS benefit from shared (mindful) experiencing and highlight MBI instructors as crucial in helping them understand and practice mindfulness. Involving PwMS in design, delivery, and iterative refinement would make MBIs more relevant to those taking part.IMPLICATIONS FOR REHABILITATIONBoth face-to-face and online Mindfulness-based interventions (MBIs) appear acceptable to PwMS and, ideally, people should be offered a choice in training modality.PwMS derive benefit from undertaking MBIs with their peers, where a sense of camaraderie and belonging develop through shared (mindful) experiences.Instructors delivering MBIs for PwMS should be knowledgeable about the condition; participants describe how the instructor has a key role in helping them practice mindfulness effectively in the context of unpleasant experiences associated with MS.MBIs tailored for PwMS should include a pre-course orientation session, clearly articulate how mindfulness practices can help with MS, provide well-organized course materials in large font size, and deliver individual mindfulness practices flexibly depending on participant need.

Grieving a disrupted biography: an interpretative phenomenological analysis exploring barriers to the use of mindfulness after neurological injury or impairment

BACKGROUND

Mindfulness has demonstrated strong utility for enhancing self-management and health outcomes in chronic illness. However, sensation-focused mindfulness techniques may not be appropriate for clinical populations with neurological injury. This study aimed to identify how expert mindfulness teachers with sensory loss/impairment naturalistically adapt and experience mindfulness. We aimed to highlight the rationale for and barriers to mindfulness practice when living with sensory loss.

METHODS

A qualitative, semi-structured interview design was used, analysed via Interpretative Phenomenological Analysis (IPA). Eight (5 females, 3 males) mindfulness teachers with neurological injury were recruited via a national registry of Mindfulness for Health teachers. Interviews (range: 50-93 min) were completed, transcribed verbatim and analysed idiographically for descriptive, linguistic and conceptual themes, before a cross-case analysis was completed.

RESULTS

Two superordinate themes were identified: (1) Overcoming a disrupted biography; and (2) Proactive self-management. These themes considered the challenge of reconciling, through grief, a past health status with the present reality of living with sensory loss due to Spinal Cord Injury, Multiple Sclerosis or Functional Neurological Disorder. Mindfulness was experienced as a method by which proactive choices could be made to maintain control and autonomy in health, reducing perceptions of suffering, psychological distress, cognitive reactivity and rumination.

CONCLUSIONS

Mindfulness was found to support the self-management of health after neurological injury/impairment. Mindfulness meditation presented an initial challenge as trauma and grief processes were (re-)activated during mindfulness sessions. However, mindfulness was found to support the resolution of these grief processes and encourage adaptive approach-based coping and acceptance of health and neurological impairment/injury.

A Systematic Review of the Effectiveness of Self-Compassion-Related Interventions for Individuals With Chronic Physical Health Conditions

Self-compassion, defined as a mindful way of coping with pain and suffering by showing kindness, care, and concern towards the self, may improve psychological adjustment in people living with a chronic physical health condition (CPHC). Various studies illustrate that self-compassion is associated with positive outcomes in general. The aim of this systematic review is to establish the effect of compassion-related therapies on self-compassion specifically in people with CPHCs. Secondary aims are to (a) establish the effect on other psychological and physiological outcomes and (b) explore the relative effectiveness of different therapy types among those identified. Cochrane, Embase, Medline, PsycINFO, and CINAHL databases were searched using "compassion" AND "chronic disease" AND "psychological outcomes" and their synonyms, from 2004 to March 2019. Eligible studies had an experimental design using a self-compassion scale with an adult population. Risk of bias (RoB) was assessed using the Cochrane RoB tool. Effect sizes were calculated for study outcomes. Fifteen studies, including a total of 1,190 participants, 7 different CPHCs, and 11 types of therapies, were included in the review. Nearly all included therapies significantly increased self-compassion with medium to large effect sizes, and reported positive outcomes, such as decreased depression. None of the therapy types appeared clearly superior to the others. Findings from this review show that included therapies increased self-compassion and improved various outcomes, which may represent clinically significant benefits for patients. However, there is a need to further understand how self-compassion exerts its benefits and determine the best methods to increase self-compassion.

Mindfulness- and Acceptance-Based Interventions for Symptom Reduction in Individuals With Multiple Sclerosis: A Systematic Review and Meta-Analysis

OBJECTIVE

To examine the effects of mindfulness- and acceptance-based interventions (MABIs) on reducing symptoms in individuals with multiple sclerosis (MS).

DATA SOURCES

A comprehensive search was conducted within the PubMed, CINAHL, PsycINFO, and SCOPUS databases for articles published from inception to July 3, 2020.

STUDY SELECTION

Randomized controlled trials (RCTs) were included if MABIs were provided to individuals with MS exclusively, with reported pre-and posttest results in symptoms of depression, anxiety, stress, fatigue, or pain.

DATA EXTRACTION

Characteristics of the included RCTs and data for meta-analysis were extracted. The quality of the included RCTs was assessed using the Cochrane Collaboration risk of bias tool.

DATA SYNTHESIS

A random effects model with the inverse variance method was used with effect size reported as standardized mean difference. Heterogeneity was assessed using the I² statistic.

RESULTS

Twenty-three RCTs met the eligibility criteria. Meta-analyses found large effects of MABIs on reducing depressive symptoms, anxiety, stress, and pain, as well as a moderate effect of MABIs on reducing fatigue at the immediate posttest. Large effects of MABIs on reducing depressive symptoms, anxiety, and stress at follow-up were also found, whereas a moderate effect on reducing fatigue was found at follow-up. There was no significant effect of MABIs on reducing pain at follow-up.

CONCLUSIONS

Fewer studies were included in meta-analyses for pain at the immediate posttest and follow-up and stress and fatigue at follow-up. The overall risk of bias was unclear. Future high-quality studies with follow-up evaluations are needed to support effects of MABIs on reducing symptoms in individuals with MS and examine intervention features that increase and maintain effects.

Effects of mindfulness-and acceptance-based interventions on quality of life, coping, cognition, and mindfulness of people with multiple sclerosis: a systematic review and meta-analysis

This systematic review and meta-analysis of randomized controlled trials (RCTs) examined effects of mindfulness- and acceptance-based interventions (MABIs) on quality of life (QoL), coping, cognition, and mindfulness among people with multiple sclerosis (MS). Four electronic databases were searched to 3 July 2020. Data was combined in a random-effects meta-analysis model. Eighteen RCTs met the eligibility criteria. Meta-analyses at the immediate posttest found: moderate effects of MABIs on QoL, coping, and attention; and a large effect on memory. A large effect of MABIs on QoL was found at follow-up. There was no significant effect of MABIs on mindfulness. Relatively fewer studies in outcomes other than QoL were found, and the overall risk of bias across the included 18 RCTs was unclear. Future high-quality studies with follow-up evaluations are needed to support effects of MABIs on QoL, coping, cognition, and mindfulness in people with MS and examine intervention features that increase and maintain effects.

The emotional disorders associated with multiple sclerosis

Multiple sclerosis (MS) is associated with a high prevalence of emotional and mood disorders. Emotional disorders may worsen during illness progression and affect the quality of life of patients and their families. MS is often associated with depression, with an increased risk of suicide, poor adherence to treatment, decreased functional status, and quality of life. The diagnosis and treatment of emotional and mood disorders in these patients is often challenging since several symptoms of these disorders overlap with those of MS. Other prevalent emotional disorders in MS include bipolar disorder, anxiety disorders, emotional blunting (apathy), and pseudobulbar affect. Early recognition and treatment of these comorbidities could contribute to the reduction of disability and even to decreased mortality. The aim of this chapter is to provide an up-to-date review of mood and emotional disorders that are often associated with MS, focusing on their epidemiology, clinical features, pathogenesis, assessment, and treatment. The interplay between the psychosocial impact of the chronic disability and the demyelinating structural lesions of the brain in precipitating emotional and mood disorders is discussed, as well as its implications for diagnosis and treatment.

A randomised controlled trial to test the feasibility of online mindfulness programs for people with multiple sclerosis

BACKGROUND

Practicing mindfulness may improve mental health and reduce pain in people with multiple sclerosis (MS). Since participating in face-to-face mindfulness programs can be challenging for people with MS, exploring alternative ways of delivering these programs is necessary. The objective of this trial was to assess feasibility of two different eight-week online mindfulness programs across five domains: recruitment, practicality, acceptability, integration of mindfulness practice, and limited efficacy testing on mental health, quality of life and pain.

METHODS

In a three-arm randomised controlled mixed-method trial, participants were assigned to: 1) Mindfulness for Multiple Sclerosis (M4MS) (n=18); 2) Chair Yoga (n=18); or 3) wait-list control group (n=19) for eight weeks. Daily home practice diaries and weekly reflective journals were collected along with online questionnaires at baseline and post-intervention. Feasibility was assessed using descriptive statistics, multilevel mixed-effects regression, and content analysis.

RESULTS

Online recruitment, online program delivery and online data collection were all found to be feasible. The sign up rate was 65% and overall, 87% of the participant completed the eight-week online programs. The programs were perceived as practical and acceptable by the participants. Integration of mindfulness practice into daily life varied, with time and fatigue reported as common barriers to practice. No statistically significant differences in efficacy measures were found among groups (p>0.05).

CONCLUSION

Online mindfulness programs are feasible and acceptable for people with MS. This study provides useful insights for future trials when designing online mindfulness programs for people with MS.

Quality of life in adults with multiple sclerosis: a systematic review

OBJECTIVE

In recent years, quality of life (QoL) in multiple sclerosis (MS) has been gaining considerable importance in clinical research and practice. Against this backdrop, this systematic review aimed to provide a broad overview of clinical, sociodemographic and psychosocial risk and protective factors for QoL in adults with MS and analyse psychological interventions for improving QoL.

METHOD

The literature search was conducted in the Scopus, Web of Science and ProQuest electronic databases. Document type was limited to articles written in English, published from January 1, 2014, to January 31, 2019. Information from the selected articles was extracted using a coding sheet and then qualitatively synthesised.

RESULTS

The search identified 4886 records. After duplicate removal and screening, 106 articles met the inclusion and exclusion criteria for qualitative synthesis and were assessed for study quality. Disability, fatigue, depression, cognitive impairment and unemployment were consistently identified as QoL risk factors, whereas higher self-esteem, self-efficacy, resilience and social support proved to be protective. The review analysed a wide spectrum of approaches for QoL psychological intervention, such as mindfulness, cognitive behavioural therapy, self-help groups and self-management. The majority of interventions were successful in improving various aspects of QoL.

CONCLUSION

Adequate biopsychosocial assessment is of vital importance to treat risk and promote protective factors to improve QoL in patients with MS in general care practice.

Transdiagnostic treatment of emotional disorders in people with multiple sclerosis: randomized controlled trial

BACKGROUND

Multiple sclerosis (MS) is a neurodegenerative disease of the central nervous system. MS is significantly associated with a high rate of psychological, behavioral, and emotional consequences. Despite the frequent mental disorders, high rate of psychological comorbidities, and emotional problems in people with MS (PwMS), these conditions are often underdiagnosed and undertreated. This study aimed to examine the efficacy of a group format of the unified protocol for the transdiagnostic treatment of emotional disorders in adult PwMS associated with an emotional disorder.

METHODS

Seventy adult PwMS were randomized using an internet-based computer system to either the unified protocol (n = 35) or treatment as usual condition. The assessment protocol included semi-structured clinical interviews and self-reports evaluating diagnostic criteria, depression, anxiety and worry symptoms, emotional dysregulation, and affectivity.

RESULTS

The parametric test of analysis of covariance, followed the intent to treat analyses, revealed the unified protocol significantly changed depression symptoms (Cohen's d = 1.9), anxiety symptoms (Cohen's d = 2.16), worry symptoms (Cohen's d = 1.27), emotion dysregulation (Cohen's d = 0.44), positive affect (Cohen's d = 1.51), and negative affect (Cohen's d = 1.89) compared with the control group. The unified protocol also significantly improved outcome scores at the end of treatment relative to baseline (p < .001).

CONCLUSION

The findings support that the unified protocol could be an additional efficient psychological treatment for PwMS. Trial registration IRCT, number: IRCT20190711044173N1. Registered 31october 2019, https://en.irct.ir/user/trial/40779/view .

The influence of trait mindfulness on depression in multiple sclerosis: potential implications for treatment

PURPOSE

This study seeks to add to existing literature on depression and illness intrusiveness in chronic disorders by examining, (1) how the perceived intrusiveness of multiple sclerosis (MS) leads to depression, (2) and the mediating role trait mindfulness plays in this relationship METHODS: Participants (N = 755) were persons with MS (PwMS) recruited through the North American Research Committee on MS (NARCOMS) registry (a larger study). Participants completed the Illness Intrusiveness Ratings Scale, the Hospital Anxiety and Depression Scale and the Mindful Attention Awareness Scale. A mediation model assessed if trait mindfulness mediates the relationship between illness intrusiveness and depression RESULTS: Illness intrusiveness predicted trait mindfulness (a =  - 4.54; p < .001), trait mindfulness predicted depression (b =  - .04; p < .001); there was a direct effect of illness intrusiveness on depression (c' = 2.53; p < .001) and an indirect effect on depression (ab = .17, 95% BCa CI [.10, .25]) when trait mindfulness was in the model, which represented a medium size effect, R²_med = .10 [95% CI .07, .14] CONCLUSION: Trait mindfulness mediates the relationship between illness intrusiveness and depression in PwMS. Providers could provide psychoeducation on the benefits of mindfulness and mindfulness-based interventions.

The effectiveness of emotional wellness programs on mental health outcomes for adults with multiple sclerosis: a systematic review and meta-analysis

BACKGROUND

People with multiple sclerosis (MS) have a greater prevalence of depression and anxiety than the general population. Emotional wellness programs (any psychological or psychosocial interventions that focus on awareness, acceptance, managing, or challenging thoughts and feelings) could be important for people with MS. However, there have been no reviews on the effectiveness of emotional wellness programs for people with MS. The objective of this review was to determine the effectiveness of emotional wellness programs on mental health outcomes for adults with MS.

INCLUSION CRITERIA

Randomised controlled trials (RCTs) and quasi-experimental trials evaluating emotional wellness programs for adults with any form of MS were included. Mental health outcomes included were depression, anxiety, quality of life, and stress. The comparator groups were waitlist controls, usual care, or another intervention.

METHODS

This review was registered with PROSPERO (registration number CRD42019131082) and conducted in accordance with PRISMA guidelines. CINAHL, Cochrane, MEDLINE, PsycInfo, Web of Science, ProQuest Dissertations and Theses, Cochrane register of Controlled Trials, and Google Scholar were searched for English- language publications. Titles and abstracts were initially screened, followed by a screen of full text articles. Studies were critically appraised for methodological quality using the JBI standardised critical appraisal checklists. Data were extracted on intervention details, study outcome measures, behaviour change techniques, and results. Random effects meta-analyses were performed for outcomes assessed in at least five studies, with results reported as the standardised mean difference (SMD).

RESULTS

This review comprised 25 RCTs and four quasi-experimental studies (n participants=2323); 21 were included in meta-analyses. Meta-analyses produced statistically significant results favouring the interventions (SMD (95% CI) for depression -0.55 (-0.87, -0.24); anxiety -0.42 (-0.70, -0.14); quality of life 0.28 (0.14, 0.43); and stress -1.00 (-1.58, -0.43)). The most commonly used behaviour change techniques were behaviour practice/rehearsal, social comparison, and social support.

CONCLUSIONS

This review provides evidence to support the effectiveness of emotional wellness programs for improving mental health outcomes in adults with MS. However, these findings should be interpreted with caution given the high degree of heterogeneity between the studies, and potential for biases in analysis due to missing data and/or incomplete reporting.

Effects of eight weeks of simple mindfulness stress reduction training on anxiety, depression, and sleep quality in elderly patients with functional dyspepsia

BACKGROUND

Functional dyspepsia (FD) tends to cause anxiety and depression in patients and affect their sleep quality. Mental and psychological factors play an important role in the development of FD. Therefore, it is necessary to strengthen the understanding of the psychological status of FD patients to better implement targeted intervention measures to reduce negative emotions and improve sleep quality.

AIM

To observe the effects of 8 wk of simple mindfulness stress reduction training on anxiety, depression, and sleep quality in elderly patients with FD.

METHODS

Ninety elderly FD patients admitted to The Second Hospital of Jinhua, Zhejiang Province from March 2017 to June 2019 were selected as study subjects, and they were randomly divided into either a control group or an observation group, each with 45 cases. Both groups received routine care, and the observation group was additionally given 8 wk of simple mindfulness stress reduction training intervention. Changes in anxiety and depression scores, Pittsburgh sleep quality index score, sleep latency, and sleep duration were recorded before and after intervention.

RESULTS

Self-rating anxiety scale and self-rating depression scale scores in the two groups were significantly lower than those in the control group (P < 0.05). Compared with those before intervention, sleep quality was significantly improved (P < 0.05), sleep latency was significantly shortened (P < 0.05), and sleep duration was significantly prolonged (P < 0.05) in both groups after intervention; the observation group was significantly better than the control group in these indexes (P < 0.05).

CONCLUSION

Eight weeks of simple mindfulness stress reduction training can effectively relieve anxiety, depression, and other negative emotions and improve sleep quality in elderly patients with FD.

Behavioral Interventions in Multiple Sclerosis

IMPORTANCE

Multiple sclerosis (MS) is a complex and unpredictable neurologic disease affecting nearly 1 million people in the US. People with MS commonly experience multiple physical and psychological symptoms such as depression, anxiety, stress, fatigue, and pain that impact functioning and quality of life. Subsequently, living with MS requires routine management of MS symptoms, adaptation to challenges, and engagement in health behaviors to promote well-being over time.

OBSERVATIONS

There is considerable evidence that behavioral interventions that increase cognitive and/or behavioral skills to address the challenges of day-to-day life with MS can promote resilience and reduce overall distress associated with this chronic and unpredictable disease. Brief group-based cognitive-behavioral therapy (CBT) and CBT-based interventions (eg, self-management) have been shown to reduce symptoms of depression, anxiety, stress, fatigue, and pain in people with MS, including via telehealth delivery. Likewise, mindfulness-based interventions have been shown to improve depression, anxiety, stress, fatigue, and quality of life in people with MS. Behavioral interventions also have been shown to improve health behaviors such as physical activity and adherence to disease modifying therapies in MS. Unlike other treatment options, behavioral interventions can be delivered in various formats (eg, in-person, telehealth), are time-limited, and cause few (if any) undesirable systemic side effects.

CONCLUSIONS

Behavioral intervention is an integral component of interprofessional care and key aspect of living well with MS.

Using normalisation process theory to understand barriers and facilitators to implementing mindfulness-based stress reduction for people with multiple sclerosis

Objectives

To study barriers and facilitators to implementation of mindfulness-based stress reduction for people with multiple sclerosis.

Methods

Qualitative interviews were used to explore barriers and facilitators to implementation of mindfulness-based stress reduction, including 33 people with multiple sclerosis, 6 multiple sclerosis clinicians and 2 course instructors. Normalisation process theory provided the underpinning conceptual framework. Data were analysed deductively using normalisation process theory constructs (coherence, cognitive participation, collective action and reflexive monitoring).

Results

Key barriers included mismatched stakeholder expectations, lack of knowledge about mindfulness-based stress reduction, high levels of comorbidity and disability and skepticism about embedding mindfulness-based stress reduction in routine multiple sclerosis care. Facilitators to implementation included introducing a pre-course orientation session; adaptations to mindfulness-based stress reduction to accommodate comorbidity and disability and participants suggested smaller, shorter classes, shortened practices, exclusion of mindful-walking and more time with peers. Post-mindfulness-based stress reduction booster sessions may be required, and objective and subjective reports of benefit would increase clinician confidence in mindfulness-based stress reduction.

Discussion

Multiple sclerosis patients and clinicians know little about mindfulness-based stress reduction. Mismatched expectations are a barrier to participation, as is rigid application of mindfulness-based stress reduction in the context of disability. Course adaptations in response to patient needs would facilitate uptake and utilisation. Rendering access to mindfulness-based stress reduction rapid and flexible could facilitate implementation. Embedded outcome assessment is desirable.

Mindfulness-based interventions for mental well-being among people with multiple sclerosis: a systematic review and meta-analysis of randomised controlled trials

OBJECTIVE

Impairment of mental well-being (anxiety, depression, stress) is common among people with multiple sclerosis (PwMS). Treatment options are limited, particularly for anxiety. The aim of this study was to update our previous systematic review (2014) and evaluate via meta-analysis the efficacy of mindfulness-based interventions (MBIs) for improving mental well-being in PwMS.

METHODS

Systematic searches for eligible randomised controlled trials (RCTs) were carried out in seven major databases (November 2017, July 2018), using medical subject headings and key words. Studies were screened, data extracted, quality appraised and analysed by two independent reviewers, using predefined criteria. Study quality was assessed using the Cochrane Collaboration risk of bias tool. Mental well-being was the primary outcome. Random effects model meta-analysis was performed, with effect size reported as standardised mean difference (SMD).

RESULTS

Twelve RCTs including 744 PwMS were eligible for inclusion in the systematic review, eight had data extractable for meta-analysis; n=635. Ethnicity, socioeconomic status, comorbidity and disability were inconsistently reported. MBIs varied from manualised to tailored versions, lasting 6-9 weeks, delivered individually and via groups, both in person and online. Overall SMD for mental well-being (eight studies) was 0.40 (0.28-0.53), p<0.01, I²=28%; against active comparators only (three studies) SMD was 0.17 (0.01-0.32), p<0.05, I² =0%. Only three adverse events were reported.

CONCLUSIONS

MBIs are effective at improving mental well-being in PwMS. More research is needed regarding optimal delivery method, cost-effectiveness and comparative-effectiveness.

Stress management interventions for multiple sclerosis: A meta-analysis of randomized controlled trials

Stress management interventions can help to improve mental health for adults living with multiple sclerosis. However, uncontrolled study designs may overestimate intervention effects. A systematic search of the Embase, PsycINFO, PubMed, and Scopus databases identified eight randomized controlled trials evaluating cognitive behavioral approaches for a pooled sample of 568 adults with multiple sclerosis. Both group and individual-based stress management interventions appear to be effective in promoting self-management of stress. Further research is needed to confirm the optimal timing of stress management interventions across the MS spectrum and strategies to maintain intervention effects.

The effects of cognitive behavioral and mindfulness-based therapies on psychological distress in patients with multiple sclerosis, Parkinson's disease and Huntington's disease: Two meta-analyses

OBJECTIVE

Psychological distress has a high impact on quality of life in patients with multiple sclerosis (MS), Parkinson's disease (PD), and Huntington's disease (HD). Studies have shown that cognitive behavioral therapy (CBT) and mindfulness-based therapies (MBTs) are successful in reducing psychological distress in patients with anxiety, depressive, and chronic somatic disorders. We aimed to investigate the effectiveness of these therapies in MS, PD, and HD patients.

METHODS

We performed a comprehensive literature search in PubMed, PsycINFO, Embase and the Cochrane Central Register of Controlled Trials up to March 2018. Randomized controlled trials (RCTs) investigating a CBT or MBT and reporting psychological outcome measures were included. Two separate meta-analyses were performed; one on studies comparing psychological therapy with a treatment as usual or waitlist condition and one on studies with active treatment control conditions.

RESULTS

The first meta-analysis (N = 12 studies, 8 in MS and 4 in PD populations) showed a significant effect size of g = 0.51 in reducing psychological distress. The second meta-analysis (N = 7 studies, in MS populations) showed a mean effect size of g = 0.36. No RCTs were found in HD populations. The overall quality of the included studies was low and considerable heterogeneity was found. No evidence was found for publication bias.

CONCLUSION

CBT and MBTs have a small to moderate effect on reducing psychological distress in patients with PD and MS. However, more research with better methodological quality and larger study samples is warranted, especially in HD patient populations.

Review of Two Popular Eating Plans within the Multiple Sclerosis Community: Low Saturated Fat and Modified Paleolithic

The precise etiology of multiple sclerosis (MS) is unknown but epidemiologic evidence suggests this immune-mediated, neurodegenerative condition is the result of a complex interaction between genes and lifetime environmental exposures. Diet choices are modifiable environmental factors that may influence MS disease activity. Two diets promoted for MS, low saturated fat Swank and modified Paleolithic Wahls Elimination (WahlsElim), are currently being investigated for their effect on MS-related fatigue and quality of life (NCT02914964). Dr. Swank theorized restriction of saturated fat would reduce vascular dysfunction in the central nervous system (CNS). Dr. Wahls initially theorized that detailed guidance to increase intake of specific foodstuffs would facilitate increased intake of nutrients key to neuronal health (Wahls™ diet). Dr. Wahls further theorized restriction of lectins would reduce intestinal permeability and CNS inflammation (WahlsElim version). The purpose of this paper is to review the published research of the low saturated fat (Swank) and the modified Paleolithic (Wahls™) diets and the rationale for the structure of the Swank diet and low lectin version of the Wahls™ diet (WahlsElim) being investigated in the clinical trial.

Impact of mindfulness-based stress reduction for people with multiple sclerosis at 8 weeks and 12 months: A randomized clinical trial

BACKGROUND

Mindfulness training is often used as a therapeutic intervention to manage stress and enhance emotional well-being, yet trials for multiple sclerosis (MS) are limited and few have used an active control.

OBJECTIVE

Assess the feasibility of mindfulness-based stress reduction (MBSR) for people with MS and evaluate the efficacy of MBSR compared to an education control.

METHODS

We conducted a single-blind, randomized trial of MBSR versus education control among 62 adults with MS. Primary outcomes were measures of feasibility. Secondary outcomes included perceived stress, anxiety, depression, fatigue, pain, resilience, and the Paced Auditory Serial Addition Test, assessed at baseline, 8 weeks, and 12 months. Mean scores for secondary outcome measures were compared between groups at each time point and within groups across time by analyses of covariance or paired t-tests, respectively.

RESULTS

Successful recruitment and retention demonstrated feasibility. Improvements in several secondary outcomes were observed among both MBSR and control groups. However, differences between the groups were not statistically significant at either 8 weeks or 12 months.

CONCLUSION

Emotional well-being improved with both MBSR and education. Spontaneous improvement cannot be ruled out as an explanation for findings and additional studies that evaluate the impact of mindfulness training to improve emotional health are warranted.

Into the Moment: Does Mindfulness Affect Biological Pathways in Multiple Sclerosis?

Mindfulness was introduced in the Western world by Jon Kabat-Zinn in 1979. He defined it as "awareness that arises through paying attention, on purpose, in the present moment, non-judgmentally." Since then, research on mindfulness-based interventions (MBIs) has increased exponentially both in health and disease, including in patients with neurodegenerative diseases such as dementia and Parkinson's disease. Research on the effect of mindfulness and multiple sclerosis (MS) only recently gained interest. Several studies completed since 2010 provided evidence that mindfulness improves quality of life (QoL), depression and fatigue in MS patients. In addition to patient-reported outcome measures, potential effects on cognitive function have been investigated only to a very limited extent. However, research on laboratory biomarkers and neuroimaging, capable to deliver proof-of-concept of this behavioral treatment in MS, is mainly lacking. In this perspective, we illustrate possible neurobiological mechanisms, including the tripartite interaction between the brain, the immune system and neuroendocrine regulation, through which this treatment might affect multiple sclerosis symptoms. We propose to (1) include immunological and/or neuroimaging biomarkers as standard outcome measures in future research dedicated to mindfulness and MS to help explain the clinical improvements seen in fatigue and depression; (2) to investigate effects on enhancing cognitive reserve and cognitive function; and (3) to investigate the effects of mindfulness on the disease course in MS.
