Performance in daily activities, cognitive impairment and perception in multiple sclerosis patients and their caregivers

Inter-Rater Reliability of the Pizzi Health and Wellness Assessment (PHWA)

The objective of this study is to determine the inter-rater reliability of the Pizzi Health and Wellness Assessment (PHWA) by comparing the consistency in scores between clients and their caregivers in the following areas of participation: social, physical, family, occupational, mental/emotional, and spiritual. A retrospective inter-rater correlational design was used to analyze the agreement of scores from a convenience sample consisting of two groups: clients with disabilities (n = 19) and their healthy caregivers (n = 19). Inter-rater reliability was calculated using correlations for the PHWA as a whole, and for the current level of participation and wishing to improve participation subsections. Inter-rater reliability as calculated by an Intraclass Correlation Coefficient, and either the Pearson or Spearman rho correlation and found to be reliable between clients and caregivers (rICC = .636, p < .001; rho = .642, p < .001). More specifically, current level of participation demonstrated acceptable reliability (rICC = .513, p < .001; r = .521, p < .001) as did wishing to improve participation (rICC = .689, p < .001; r = .725, p < .001). This supports the PHWA as a clinically relevant health and wellness occupational therapy assessment.

Paradigm shifts in multiple sclerosis management: Implications for daily clinical practice

Multiple sclerosis (MS) is the most common chronic inflammatory neurological disease. The emergence of disease-modifying therapies (DMTs) has greatly improved disease activity control and progression of disability in MS patients. DMTs differ in their mode of action, route of administration, efficacy, and safety profiles, offering multiple options for clinicians. Personalized medicine aims at tailoring the therapeutic strategy to patients' characteristics and disease activity but also patients' needs and preferences. New therapeutic options have already changed treatment paradigms for patients with active relapsing MS (RMS). The traditional approach consists in initiating treatment with moderate-efficacy DMTs and subsequently, escalating to higher-efficacy DMTs when there is evidence of clinical and/or radiological breakthrough activity. Recent real-world studies suggest that initiation of high-efficacy DMTs from disease onset can improve long-term outcomes for RMS patients. In this article, we review different treatment strategies and discuss challenges associated with personalized therapy.

Motor, cognitive, and combined rehabilitation approaches on MS patients' cognitive impairment

BACKGROUND

At the moment, the possible options for the management of cognitive dysfunctions in patients with MS (pMS) are pharmacological interventions, cognitive rehabilitation (CR), and physical exercise. However, worldwide, multimodal programs are infrequently applied in pMS and CR is not easily accessible through the National Health System as MR.

OBJECTIVE

The aim of the study is to explore if the combination of motor and cognitive rehabilitation may favor better outcomes on cognitive efficiency compared to separate trainings.

METHODS

Forty-eight pMS were submitted to detailed neuropsychological and motor assessments, before (T0) and after (T1) having performed one of three rehabilitation conditions (two cognitive trainings/week-Reha1; one cognitive and one motor training/week-Reha2; two motor trainings/week-Reha3, for 12 weeks); they were randomly assigned to one condition or another. The CR was focused on memory functioning and performed with the Rehacom program.

RESULTS

No significant differences in age, sex, education, and disease course were found between the three groups (sig. > .05). Reha1 patients increased only their cognitive performance, and Reha3 only increased their motor performance, while Reha2 increased both cognitive and motor performances. This benefit was also confirmed by the cognitive efficiency expressed by the Cognitive Impairment Index.

CONCLUSIONS

These data confirm that to include cognitive training within rehabilitation programs may induce important benefits in pMS. Furthermore, pMS seem to benefit from a combined approach (cognitive and motor) more than from CR and motor rehabilitation separately (ClinicalTrial.gov ID: NCT05462678; 14 July 2022, retrospectively registered).

Neural mechanisms underlying state mental fatigue: a systematic review and activation likelihood estimation meta-analysis

Sustained performance of cognitive tasks could lead to the development of state mental fatigue characterized by subjective sensation of mental weariness and decrease in cognitive performance. In addition to the occupational hazards associated with mental fatigue, it can also affect physical performance reducing endurance, balance, and sport-specific technical skills. Similarly, mental fatigue is a common symptom in certain chronic health conditions such as multiple sclerosis affecting quality of life of the patients. Despite its widely acknowledged negative impact, the neural mechanisms underlining this phenomenon are still not fully understood. We conducted a systematic review and activation likelihood estimation (ALE) meta-analysis of functional neuroimaging studies investigating the effect of mental fatigue due to time-on-task (TOT) on brain activity to elucidate the possible underlying mechanisms. Studies were included if they examined change in brain activity induced by experimental mental fatigue (TOT effect) or investigated the relationship between brain activity and subjective mental fatigue due to TOT. A total of 33 studies met the review's inclusion criteria, 13 of which were included in meta-analyses. Results of the meta-analyses revealed a decrease in activity with TOT in brain areas that constitute the cognitive control network. Additionally, an increased activity with TOT, as well as negative relationship with subjective mental fatigue was found in parts of the default mode network of the brain. The changes in cognitive control and the default mode networks of the brain due to state mental fatigue observed in this study were discussed in relation to the existing theories of mental fatigue.

“I wanna live and not think about the future” what place for advance care planning for people living with severe multiple sclerosis and their families? A qualitative study

Background

Little is known about how people with multiple sclerosis (MS) and their families comprehend advance care planning (ACP) and its relevance in their lives.

Aim

To explore under what situations, with whom, how, and why do people with MS and their families engage in ACP.

Methods

We conducted a qualitative study comprising interviews with people living with MS and their families followed by an ethical discussion group with five health professionals representing specialties working with people affected by MS and their families. Twenty-seven people with MS and 17 family members were interviewed between June 2019 and March 2020. Interviews and the ethical discussion group were audio-recorded and transcribed verbatim. Data were analysed using the framework approach.

Results

Participants’ narratives focused on three major themes: (i) planning for an uncertain future; (ii) perceived obstacles to engaging in ACP that included uncertainty concerning MS disease progression, negative previous experiences of ACP discussions and prioritising symptom management over future planning; (iii) Preferences for engagement in ACP included a trusting relationship with a health professional and that information then be shared across services. Health professionals’ accounts from the ethical discussion group departed from viewing ACP as a formal document to that of an ongoing process of seeking preferences and values. They voiced similar concerns to people with MS about uncertainty and when to initiate ACP-related discussions. Some shared concerns of their lack of confidence when having these discussions.

Conclusion

These findings support the need for a whole system strategic approach where information about the potential benefits of ACP in all its forms can be shared with people with MS. Moreover, they highlight the need for health professionals to be skilled and trained in engaging in ACP discussions and where information is contemporaneously and seamlessly shared across services.

The Relationship Between Adaptation to Disease and Self-care Agency Levels in Patients With Multiple Sclerosis

ABSTRACT

BACKGROUND: Multiple sclerosis (MS) is an inflammatory and demyelinating disorder of the central nervous system. The patients with MS have some difficulties in physical, social, and psychological functions. This study was carried out to determine the relationship between the adaptation levels of patients with MS to the disease and their self-care agency levels. METHODS: This study used a descriptive design and was carried out in a university hospital's neurology clinic and outpatient clinic between July 2019 and March 2020. The sample size was determined as 258 using the known universe sampling method. Data were collected using the "Adaptation to Chronic Illness Scale," the "Self-Care Agency Scale," and a "Patient Identification Form." Spearmen correlation analysis was used to evaluate the data. RESULTS: The mean age of the patients participating in the study was 41.36 (0.74) years, 74% of them had MS for more than 3 years, 58% had their last attack more than a year ago, and 27% had balance problems. The adaptation levels of patients to the disease (76.79 [0.57]) and their self-care agency (88.42 [1.34]) were slightly higher than the moderate level. A moderate-level, significant, and positive correlation was found between the adaptation level of the patients to the chronic illness and their self-care agency levels (r = 0.310, P = .000). CONCLUSION: It was concluded that there was a moderate-level, significant, and positive correlation between the patients' level of adaptation to MS disease and the level of their self-care agency. We recommend the provision of supportive professional training to patients with MS on their disease.

Cost-effectiveness of adding Sativex® spray to spasticity care in Belgium: using bootstrapping instead of Monte Carlo simulation for probabilistic sensitivity analyses

BACKGROUND

Uncertainty in model-based cost-utility analyses is commonly assessed in a probabilistic sensitivity analysis. Model parameters are implemented as distributions and values are sampled from these distributions in a Monte Carlo simulation. Bootstrapping is an alternative method that requires fewer assumptions and incorporates correlations between model parameters.

METHODS

A Markov model-based cost-utility analysis comparing oromucosal spray containing delta-9-tetrahidrocannabinol + cannabidiol (Sativex®, nabiximols) plus standard care versus standard spasticity care alone in the management of multiple sclerosis spasticity was performed over a 5-year time horizon from the Belgian healthcare payer perspective. The probabilistic sensitivity analysis was implemented using a bootstrap approach to ensure that the correlations present in the source clinical trial data were incorporated in the uncertainty estimates.

RESULTS

Adding Sativex® spray to standard care was found to dominate standard spasticity care alone, with cost savings of €6,068 and a quality-adjusted life year gain of 0.145 per patient over the 5-year analysis. The probability of dominance increased from 29% in the first year to 94% in the fifth year, with the probability of QALY gains in excess of 99% for all years considered.

CONCLUSIONS

Adding Sativex® spray to spasticity care was found to dominate standard spasticity care alone in the Belgian healthcare setting. This study showed the use of bootstrapping techniques in a Markov model probabilistic sensitivity analysis instead of Monte Carlo simulations. Bootstrapping avoided the need to make distributional assumptions and allowed the incorporation of correlating structures present in the original clinical trial data in the uncertainty assessment.

Brain Volume and Perception of Cognitive Impairment in People With Multiple Sclerosis and Their Caregivers

Background: Cognitive impairment (CI) is common in people with multiple sclerosis (pwMS). The assessment of CI is based on neuropsychological tests and accurate anamnesis, involving the patients and caregivers (CG). This study aimed to assess the complex interplay between self-perception of CI, objective CI and the brain atrophy of MS patients, also exploring the possible differences with CI evaluated by caregivers.

Methods: Relapsing pwMS were enrolled in this study. Subjects underwent neuropsychological examination using the Brief Cognitive Assessment for Multiple Sclerosis (BICAMS) and evaluation of self-reported cognitive status using the patient-version of the Multiple Sclerosis Neuropsychological Questionnaire (p-MSNQ). Depression and anxiety were also evaluated using the Back Depression Inventory-version II (BDI-II) and Zung Anxiety Scale. Brain MRI images were acquired and brain volumes estimated. For each patient that was enrolled, we spoke to a caregiver and collected their perception of the patient's CI using the MSNQ- Caregiver version.

Results: Ninety-five MS subjects with their caregivers were enrolled. CI was detected in 51 (53.7%) patients. We found a significant correlation (p < 0.001) between BICAMS T scores and lower whole brain (Rho = 0.51), gray matter (Rho = 0.54), cortical gray matter (Rho = 0.51) volumes and lower p-MSNQ (Rho = 0.31), and cg-MSNQ (Rho = 0.41) scores. Multivariate logistic regression showed that p-MSNQ is related to a patient's anxiety to evaluate by Zung Score (p < 0.001) while cg-MSNQ to patient's brain volume (p = 0.01).

Conclusion: Our data confirm that neuropsychological evaluation results are related to the perception of CI and brain volume measures and highlight the importance of the caregiver's perception for cognitive assessment of pwMS.

Demographic features, behavioral measures, and clinical factors as predictors of cognitive function in patients with multiple sclerosis

BACKGROUND

One of the most concerning features that involves 40-70% of patients with multiple sclerosis (MS) is cognitive impairment. Moreover, it affects various aspects of patients' life. In this regard, this study was conducted to find independent predictors of cognitive function.

METHOD

We performed a cross-sectional analysis on 92 patients chosen from MS clinic of Sina hospital, Iran. After completing a general questionnaire of demographic and various clinical features, the included participants (patients with RRMS) underwent neuropsychological assessment using Minimal Assessment of Cognitive function in Multiple Sclerosis (MACFIMS), Expanded disability Status Scale (EDSS), Beck Depression Inventory II (BDI-II), and National American Adult Reading Test (NAART). An un-weighted average of MACFIMS subscales z-scores was reported as cognitive index. In order to find the association between CI and different factors, each variable was entered in a simple regression model first. Then, a univariate multiple regression model was invoked to evaluate the predictors of cognitive index in patients.

RESULTS

Simple regression for cognitive index of 92 patients (86% female) with a mean age of 33.4±7.6 years old suffering of RRMS for 6.8±4.8 years revealed patients with history of former smoking (p=0.001), sole visual symptoms as the presentation sign of the study (β=-0.341, p=0.001), lower EDSS score (β=-0.299, p=0.005), higher NAART score (β=0.416, p≤0.0001), and college education (p=0.001), had better cognitive function in our study population. Such factors including age, educational status, BDI-II score, EDSS score, and disease duration were fixed and the other significant factors entered once separately and then simultaneously in the univariate multiple linear regression model. It was revealed that former smoking (β=-0.372, p≤0.0001), NAART (β=0.304, p=0.002), and EDSS (β= -0.185, P=0.045) are associated significantly with the cognitive function of patients with multiple sclerosis.

CONCLUSION

This study demonstrated NAART, as a proxy of premorbid intelligence, history of former smoking, and EDSS score may have effects on cognitive function in MS. Future studies need to be invoked for the evaluation of the causality relation of these factors.

Understanding the impact of cognitive impairment and disease severity on activities of daily living in MS patients with different disability levels

OBJECTIVE

Physical impairments seen in people with multiple sclerosis (PwMS) affect the level of independence in activities of daily living (ADL). However, physical problems are insufficient to explain some debilitating conditions experienced by PwMS in daily life, especially in activities that require high cognitive ability. The aim of this study was to investigate the impact of cognitive impairment and disease severity on ADL in MS patients with different disability levels.

METHODS

Seventy PwMS were enrolled and divided into three groups according to their disability status. Cognitive functions were assessed with the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) and independence level in ADL was assessed with Functional Independence Measure (FIM).

RESULTS

There were significant differences between groups in FIM and FIM motor (FIMm) scores (p < 0.001), however no significant differences were found between groups in terms of FIM cognitive (FIMc) and LOTCA scores (p = 0.195 and p = 0.348 respectively). There was a moderate positive correlation between FIM and LOTCA total scores (p < 0.001) for overall sample. While there was a low correlation between LOTCA and FIMm (p = 0.008), high correlation was found between LOTCA and FIMc (p < 0.001).

CONCLUSION

Although most of the limitations in ADL can be explained by the severity of the disability in MS, the ability to perform ADL including cognitive skills was found to be similar for all disability levels. Cognitive problems should be taken into consideration as well as motor problems in the process of planning treatment programs for PwMS with any levels of disability.

Effects of Massage Therapy on Multiple Sclerosis: a Case Report

BACKGROUND

Multiple Sclerosis (MS) is characterized by degeneration of the myelin sheath of an axon resulting in decreased transmission of nerve impulses. It is an autoimmune disease with periods of exacerbation and remission. Types of MS include relapsing-remitting, acute progressive, chronic progressive attack-remitting, and benign. Symptoms vary from patient to patient. Common symptoms include fatigue, spasticity, swelling, and altered gait. MS is commonly treated with medications that help relieve symptoms and prolong disease progression. Massage Therapy (MT), specifically Swedish techniques, have been effective in treating MS.

OBJECTIVE

To examine the effects of MT on mobility, fatigue, and edema in a patient with MS.

METHODS

An MT student from MacEwan University's 2,200-hour Massage Therapy program administered five MT treatments over a six-week period to a 58-year-old female diagnosed with MS 11 years earlier. She presented with symptoms of decreased mobility, fatigue, and left ankle edema. Assessment included active and passive range of motion (ROM), myotomes, dermatomes, reflexes, and orthopedic tests. Goals for the treatment sessions were to increase mobility, decrease fatigue, and decrease edema. Assessment measures included the Timed-Up-and-Go (TUG) test for mobility, the Modified Fatigue Impact Scale (MFIS) to measure fatigue, and Figure-8 ankle measurement to measure edema. Techniques used included Swedish massage, passive ROM, manual lymphatic drainage (MLD), and home-care exercises.

RESULTS

Little change was noted in mobility. The patient's fatigue level and left ankle edema decreased.

CONCLUSION

The results suggest that MT is effective in reducing fatigue and edema in a patient with MS. Future studies are needed to evaluate the correlation between mobility and massage.

Montreal cognitive assessment for evaluating cognitive impairment in multiple sclerosis: a systematic review

This study aims to systematically review the evidence on the accuracy of the Montreal Cognitive Assessment (MoCA) test for evaluating the presence of cognitive impairment in patients with multiple sclerosis (MS) and to outline the quality and quantity of research evidence available about the use of MoCA in this population. We conducted a systematic literature review, searching five databases from inception until May 2020. We identified fourteen studies that met the inclusion criteria: three cross-sectional studies and two case - control studies comparing MoCA to a battery of tests, one study comparing MoCA to Mini-Mental State Examination (MMSE), and eight studies estimating the prevalence of cognitive impairment in individuals with MS. Publication period ranged from 2012 to 2020. Although the MoCA test demonstrated good sensitivity and specificity when used at the recommended threshold of 26, a lower threshold than the original cut-off was also reported to be useful for optimal screening, as it lowers false positive rates and improves diagnostic accuracy. Furthermore, in MS patients without subjective cognitive complaints, a cutoff of 27 could provide a better balance between the sensitivity and the specificity of the test. In patients with MS, the MoCA provides information on general cognitive functions disturbances. Nonetheless, more studies are required to examine the optimum cut-off score for detecting cognitive impairments in MS patients.

Cognitive reserve is a determinant of social and occupational attainment in patients with pediatric and adult onset multiple sclerosis

BACKGROUND

There is limited information on socio-professional attainment in pediatric-onset multiple sclerosis (POMS) compared with adult-onset MS (AOMS).

OBJECTIVES

To assess socio-professional outcomes in POMS and AOMS and variables influencing these outcomes.

METHODS

One-hundred-fifteen AOMS and 111 POMS patients underwent neuropsychological testing (Brief Repeatable Battery, Stroop test), assessment of cognitive reserve (CR) (education, National Adult reading Test -NART, Barratt Simplified Measure of Social Status), fatigue (Fatigue Severity Scale), depression (Montgomery-Åsberg Depression Rating Scale), socio-professional performance (Work and Social Adjustment Scale -WSAS). Prognostic factors were assessed using logistic and linear multivariable regression analyses.

RESULTS

34.5% of patients showed CI without significant differences between AOMS and POMS. Cognitively impaired patients were older (p=0.024), had higher EDSS scores (p=0.041) and lower IQ (p<0.001) compared with cognitively preserved patients. Better WSAS scores were associated with younger age (p=0.007), lower EDSS (p<0.001) and higher educational levels (p=0.001). Fourteen POMS (13%) and six AOMS (5%) achieved a lower educational level compared with their parents (p=0.06). POMS exhibiting a lower than expected educational level, had a lower median IQ compared with the remaining subjects (101 vs 106.5; p=0.03). Unemployment rate was predicted by higher disability (p=0.044) and lower educational levels (p<0.001). Occupational complexity was positively correlated to educational level (<0.001) and NART scores (<0.040).

CONCLUSION

This study underscores the complex relationships between cognition and educational, socioeconomic and professional attainment in MS and supports a protective role of CR in both POMS and AOMS.

Cognition, Cognitive Rehabilitation, and Occupational Performance

The American Occupational Therapy Association (AOTA) asserts that occupational therapists and occupational therapy assistants, through the use of occupations and activities, facilitate clients’ cognitive functioning to enhance occupational performance, self-efficacy, participation, and perceived quality of life. Cognitive processes are integral to effective performance across the broad range of daily occupations such as work, educational pursuits, home management, and play and leisure. Cognition plays an integral role in human development and in the ability to learn, retain, and use new information to enable occupational performance across the lifespan.

This statement defines the role of occupational therapy in evaluating and addressing cognitive functioning to help clients maintain and improve occupational performance. The intended primary audience is practitioners1 within the profession of occupational therapy. The statement also may be used to inform recipients of occupational therapy services, practitioners in other disciplines, and the wider community regarding occupational therapy theory and methods and to articulate the expertise of occupational therapy practitioners in addressing cognition and challenges in adapting to cognitive dysfunction.

The minimal neuropsychological assessment of MS patients (MACFIMS): normative data of the Italian population

Cognitive impairment is common in multiple sclerosis (MS), and research has emphasized the crucial role of cognitive assessment in disease monitoring. The minimal neuropsychological assessment of MS (MACFIMS) represents one of the neuropsychological batteries most widely used throughout the world. To date, a complete validation, as well as normative values of an alternative form, is lacking in the Italian population, limiting the use of this tool in longitudinal assessment. A total of 200 healthy subjects (127 females and 73 males) were recruited from the community in 8 Italian cities and were evaluated with the MACFIMS at baseline and reassessed with an alternate form of the same battery after 12 months. Regression-based norms that account for demographic influences on test performance were calculated at each time point (baseline and follow-up). The study provides, for the first time, normative values of two forms of the MACFIMS battery for the Italian population. Data application allows clinicians to monitor the performance of cognitive functions over time and to better understand the efficacy of both pharmacological and non-pharmacological interventions in clinical practice and research.

Cognitive performance and cognitive workload in multiple sclerosis: Two different constructs of cognitive functioning?

BACKGROUND

Cognitive impairment in individuals with Multiple Sclerosis (iwMS) is traditionally diagnosed using performance measures on cognitive tests. Yet, performance on cognitive tests does not convey the amount of mental effort or cognitive workload it takes to complete the task. The main aim was to evaluate whether cognitive performance and cognitive workload are two different constructs of cognitive functioning in iwMS.

METHODS

IwMS were categorized into cognitive impairments (iwMS+, n = 10) and no cognitive impairments (iwMS-, n = 12) using their performance on Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS). Their scores on BICAMS, Stroop, and trail making tests were compared to age- and education-matched controls (n = 22). Cognitive workload was assessed using the self-reported NASA Task Load Index and the Index of Cognitive Activity, derived from pupillary response.

RESULTS

IwMS+ performed worse on most cognitive tests compared to iwMS- and controls. However, iwMS+ did not report or exhibit greater cognitive workload compared to the other groups. Potential confounding variables, such as sex, use of antidepressants, and symptoms of depression, fatigue, and dysautonomia did not influence the lack of correlation between cognitive performance and cognitive workload in all three groups.

CONCLUSION

Cognitive performance and cognitive workload seem to measure different cognitive constructs of cognitive functioning in MS. Our results suggest that iwMS+ do not show effective allocation of cognitive resources to compensate for deteriorated performance in cognitive tests.

Cognitive impairment in multiple sclerosis: An exploratory analysis of environmental and lifestyle risk factors

Background

Many potentially modifiable risk factors for MS are investigated. It is not known, however, if these factors also apply to MS-related cognitive impairment (CI), a frequent consequence of MS.

Objective

The aim of our study was to assess risk factors for CI in MS patients, focusing on environmental exposures, lifestyle and comorbidities.

Methods

We included MS patients referring to MS Centers in Florence and Barletta between 2014 and 2017. Neuropsychological performance was assessed through the Rao’s battery and Stroop test, cognitive reserve (premorbid intelligence quotient–IQ) was evaluated using the National Adult Reading Test (NART). Potential risk factors were investigated through a semi-structured questionnaire.

Results

150 patients were included. CI was detected in 45 (30%) subjects and was associated with older age (p<0.005), older age at MS onset (p = 0.016), higher EDSS score (p<0.005), progressive disease course (p = 0.048) and lower premorbid IQ score (p<0.005). As for risk factors, CI was related with lower physical activity in childhood-adolescence (p<0.005). In women, hormonal therapy resulted to be protective against CI (p = 0.041). However, in the multivariable analysis, the only significant predictors of CI were older age (p<0.05; OR 1.06, 95% CI 1.02–1.10) and lower premorbid IQ (p<0.05; OR 0.93, 95% CI: 0.88–0.98). Removing IQ from the model, CI was associated with higher EDSS (p = 0.030; OR 1.25, 95% CI 1.02–1.53) and, marginally, previous physical activity (p = 0.066; OR 0.49, 95% CI: 0.23–1.05)

Conclusions

Our findings suggest that physical activity in childhood-adolescence could be a contributor to cognitive reserve building, thus representing a potential protective factors for MS-related CI susceptible to preventive strategies.
