Investigating the relationship of theory of mind and empathy with neuroimaging, neuropsychological, and neuropsychiatric data in persons with multiple sclerosis.

Theory of Mind (ToM) is understanding others' minds. Empathy is an insight into emotions and feelings of others. Persons with multiple sclerosis (pwMS) may experience impairment in ToM and empathy. To investigate ToM, empathy, and their relationship with neuroimaging, neuropsychological, and neuropsychiatric data. 41 pwMS and 41 HC were assessed using RMET for ToM, EQ, BICAMS, HADS. Cortical and subcortical gray matter volumes were calculated with Freesurfer from 3T MRI scans. pwMS showed lower EQ scores (44.82 ± 11.9 vs 51.29 ± 9.18, p = 0.02) and worse RMET performance (22.37 ± 4.09 vs 24,47 ± 2.93, p = 0.011). Anxiety and depression were higher in pwMS. EQ correlated with subcortical (amygdala) and cortical (anterior cingulate) volumes. RMET correlated with cortical volumes (posterior cingulate, lingual). In regression analysis, amygdala volume was the single predictor of empathy performance (p = 0.041). There were no significant correlations between social cognitive tests and general cognition. A weak negative correlation was found between EQ and the level of anxiety (r = -0.342, p = 0.038) The present study indicates that pwMS have impairment on ToM and empathy. The performance of ToM and empathy in MS is linked to the volumes of critical brain areas involved in social cognition.

Feasibility of Telerehabilitation-Based Pelvic Floor Muscle Training for Urinary Incontinence in People With Multiple Sclerosis: A Randomized, Controlled, Assessor-Blinded Study.

BACKGROUND AND PURPOSE: Urinary incontinence is a common symptom in people with multiple sclerosis. The primary aim was to investigate feasibility of telerehabilitation-based pelvic floor muscle training (Tele-PFMT) and compare its effects on leakage episodes and pad usage with home exercise-based pelvic floor muscle training (Home-PFMT) and control groups. METHODS: Forty-five people with multiple sclerosis with urinary incontinence were randomized into 3 groups. Tele-PFMT and Home-PFMT groups followed the same protocol for 8 weeks, but Tele-PFMT performed exercises 2 sessions/week under a physiotherapist's supervision. The control group did not receive any specific treatment. Assessments were made at baseline, weeks 4, 8, and 12. Primary outcome measures were feasibility (compliance to exercise, patient satisfaction, and number of participants included in the study), number of leakage episodes, and pad usage. Secondary outcomes included severity of urinary incontinence and overactive bladder symptoms, sexual function, quality of life, anxiety, and depression. RESULTS: Participant eligibility rate was 19%. Patient satisfaction and compliance to exercise were significantly higher in Tele-PFMT than in Home-PFMT ( P < 0.05). No significant differences in the change of leakage episodes and pad usage were found between Tele-PFMT and Home-PFMT. No significant differences in secondary outcomes were found between PFMT groups. Participants in both the Tele-PFMT and Home-PFMT groups had significantly better scores for some measures of urinary incontinence, and overactive bladder and quality of life in compared with the control group. DISCUSSION AND CONCLUSIONS: Tele-PFMT was feasible and acceptable in people with multiple sclerosis, and this mode of delivery was associated with greater exercise compliance and satisfaction compared with Home-PFMT. However, Tele-PFMT did not exhibit superiority in terms of leakage episodes and pad usage compared with Home-PFMT. A large trial comparing Home-PFMT and Tele-PFMT is warranted.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content, available at: http://links.lww.com/JNPT/A440 ).

Challenges of persons with multiple sclerosis on ocrelizumab treatment during COVID-19 pandemic.

Background: Coronavirus disease of the 2019 pandemic caused much fear among people with chronic diseases and those on immunosuppressant treatment because of spreading knowledge that the infection has a fatal course in these populations. People with Multiple Sclerosis on ocrelizumab treatment share this fear too. We aimed to investigate treatment and lifestyle changes of people with multiple sclerosis on ocrelizumab treatment during the lockdown. Methods: We surveyed 199 of our registered multiple sclerosis patients on ocrelizumab treatment by phone. Results: In this survey, delays in treating 22 (11%) patients were not caused by fear of immunosuppressive drug use but rather by the general fear of contracting a fatal disease, which is the case during traveling and hospital visits. There was a positive correlation between living alone and treatment delay (P = .029), emphasizing the role of family support or just the presence of another person during the pandemic. Conclusion: Vaccines might soon solve the pandemic's issue, which is not the case with multiple sclerosis progression, so we should think twice before discontinuing the treatment.

Validity and reliability of "Cognitive Reserve Index Questionnaire" for the Turkish Population.

BACKGROUND: Cognitive reserve (CR) is the ability to counteract brain damage through differential recruitment of brain networks. Besides, it has also been observed that lifetime intellectual enriching skills reduce the effect of disease burden on cognitive status. The Cognitive Reserve Index questionnaire (CRIq), which is a method for the quantitative measurement and comprehensive evaluation of the CR, that individuals have accumulated throughout their lifetimes. The present study aimed to adapt CRIq to the Turkish population. METHODS: CRIq is a 20-item questionnaire consisting of 3 sub-scales (CRI-Education, CRI- Working Activity, CRI-Leisure Time). 271 females and 228 males, a total of 499 healthy volunteers participated in the study (mean age: 39.54±14.05, mean education years 13.14±4.84). Participants were evaluated with the "Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS)" and CRIq was applied. BICAMS was used to determine the validity of the CRIq. To determine the reliability, the questionnaire was applied again two weeks after the first application. Internal consistency and test-retest reliability were measured for reliability analysis. Independent sample t-test was conducted to observe the difference between genders. RESULTS: The Cronbach alpha coefficient of the questionnaire was 0.78, and the reliability of the questionnaire was acceptable. The findings showed that inter-rater reliability was quite high (ICC:0.95, 95% CI=1.000, n=36). The correlation between the first and second application of the questionnaire was found to be acceptable for both the sub-scales and the whole questionnaire. The highest CRIq scores were shown for young adults in CRI-Education and CRI-LeisureTime, for the middle-aged in CRIq-WorkingActivity, no significant differences in total CRIq scores. The males scored significantly higher in CRIq total scores than females, but there was not a significant difference in CRI-LeisureTime between genders. CONCLUSION: The Turkish version of CRIq was found to be a valid and reliable method for evaluating cognitive reserve in healthy individuals.

The relationship between cognition, depression, fatigue, and disability in patients with multiple sclerosis.

BACKGROUND: Multiple sclerosis (MS) is a chronic, progressive, and neurodegenerative central nervous system disorder. MS usually causes disability, cognitive deficiency, fatigue, and depression symptoms. OBJECTIVES: To assess cognitive functions of people with MS (pwMS) and investigate the impact of depression, fatigue, and disability on cognitive functions. METHODS: We administered the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) battery to assess 200 pwMS. The Expanded Disability Status Scale (EDSS) was used to evaluate disability levels. Fatigue Severity Scale (FSS) and the Beck Depression Inventory (BDI) were used, respectively, for fatigue and depression levels. RESULTS: EDSS and FSS scores were significantly higher in those with a disease duration of 5 years or more. Those with the EDSS ≥ 4 were found to have lower BICAMS performances and higher FSS scores. There was a significant difference in Symbol Digit Modalities Test (SDMT) performances between the groups with and without fatigue (FSS ≥ 4 and FSS < 4, respectively). When depression and fatigue symptoms concur or in the existence of just one of them or none of them, significant differences in terms of SDMT performances have been shown. CONCLUSION: The level of disability and fatigue adversely affects the cognitive functions of pwMS; depression has no significant effect. BICAMS that is specific for MS can be beneficial to assess the cognitive state of pwMS.

A comparative study of the effects of yoga and clinical Pilates training on walking, cognition, respiratory functions, and quality of life in persons with multiple sclerosis: A quasi-experimental study.

OBJECTIVE: The purpose was to investigate the effects of yoga and clinical Pilates training on walking, respiratory muscle strength, cognition, and quality of life and compare the effects of two popular exercise methods in persons with multiple sclerosis (pwMS). METHODS: Twenty-eight pwMS (Pilates group = 16, yoga group = 12) received the program once a week for eight weeks in addition to home exercises. At baseline and the end of the training, participants underwent assessments. The outcome measures were walking speed, mobility, balance confidence, respiratory muscle strength, cognition, and quality of life. RESULTS: Following the program, there was no significant difference in mobility (p = 0.482), perceived walking quality (p = 0.325), respiratory muscle strength (maximum inspiratory pressure: p = 0.263, maximum expiratory pressure: p = 0.866), and cognition (Symbol Digit Modalities Test: p = 0.324, California Verbal Learning Test-II: p = 0.514, Brief Visuospatial Memory Test-Revised: p = 0.279) between the two groups. Improvements were higher in balance confidence (p = 0.006), walking speed (p = 0.004), and quality of life (p = 0.019) in the clinical Pilates group compared to the yoga group. CONCLUSION: This study showed positive effects in walking and respiratory aspects in pwMS who received yoga and clinical Pilates training. Pilates training was superior in improving walking speed, quality of life, and balance confidence compared to yoga training.

Effect of video-based exergaming on arm and cognitive function in persons with multiple sclerosis: A randomized controlled trial.

BACKGROUND: Developments in rehabilitation technology such as video-based exergaming contributes to the treatment process as well as to increase the active participation of persons with multiple sclerosis (pwMS). The aim was to investigate the effect of video-based exergaming training on upper extremity and cognitive function as well as core stability, walking, depression, fatigue, and quality of life in pwMS. METHODS: This randomized controlled trial included 60 pwMS who were randomly divided into three groups; video-based exergaming (n = 21), conventional rehabilitation (n = 19), and control groups (n = 20). The experimental groups received therapy sessions once a week for 8 weeks. All the participants were assessed at baseline and after 8 weeks. The outcome measures included upper extremity and cognitive functions as well as core stability, walking, depression, fatigue, and quality of life measures. RESULTS: Significant improvements were observed in the primary outcome, measured by Nine-Hole Peg Test in the video-based exergaming [before= 25.8 (11.1) s; after= 22.3 (11.0) s] and conventional rehabilitation [before= 23.3 (8.1) s; after= 19.9 (3.8) s] groups (p < 0.05). Cognitive functions (with the exception of processing speed in the conventional rehabilitation group), most of the lower extremity functions, balance-related measures, fatigue and quality of life levels were significantly improved in the video-based exergaming and conventional rehabilitation groups, however, only the depression level was significantly decreased in the video-based exergaming (p < 0.05). Several significant differences were observed in the changes of the control group compared to the video-based exergaming and conventional rehabilitation groups (p < 0.05). CONCLUSION: This study suggests that video-based exergaming is almost as effective as conventional rehabilitation regarding improving walking, upper and lower extremity functions, cognitive functions, fatigue, depression, and health-related quality of life in pwMS.

The effects of Clinical Pilates training on walking, balance, fall risk, respiratory, and cognitive functions in persons with multiple sclerosis: A randomized controlled trial.

CONTEXT: Multiple sclerosis (MS) is a chronic progressive and neurodegenerative disease. Exercise programs are needed to maintain and increase functional status in persons with MS (pwMS). Pilates exercises designed by a physiotherapist can enhance participation and functionality in pwMS. OBJECTIVE: The aim of this study was to investigate the effects of Clinical Pilates training on balance, walking, fall risk, respiratory, and cognitive functions in pwMS compared with an active comparator (home exercise training). DESIGN: This study was a randomized controlled study. SETTINGS: This study was designed by researchers at Dokuz Eylül University, Izmir, Turkey. PARTICIPANTS: Forty-two pwMS were included in this randomized controlled trial. MAIN OUTCOME MEASURES: Walking, core stability, balance confidence, respiratory muscle strength, and cognitive functions were assessed before and after the program. INTERVENTIONS: The participants were randomly divided into two groups. The Pilates exercises group (n = 21) received therapy weekly for 8 weeks along with a home exercise program. The home exercise group (n = 21) was given standardized exercises reflecting routine clinical practice. The program compliance was monitored by telephone calls once a week. RESULTS: There were no significant differences in walking speed (p = 0.096), perceived walking ability (p = 0.165), and fear of falling (p = 0.385) between the Pilates and home exercise groups. Clinical Pilates training was superior to the home exercise program in walking endurance (p = 0.001), postural stability (p = 0.028), core stability (p = 0.016), respiratory (maximum inspiratory pressure: p = 0.037, maximum expiratory pressure: p = 0.008), and cognitive functions (p = 0.001-0.007). Clinical Pilates training may be preferred as an alternative method to improve balance, walking, respiratory, and cognitive functions in pwMS.

Prevalence of and risk factors for cognitive impairment in patients with relapsing-remitting multiple sclerosis: Multi-center, controlled trial.

BACKGROUND: Cognitive impairment (CI) is a common problem in multiple sclerosis (MS), may occur either in early or late phase of the disease, and impairs quality of life. OBJECTIVES: This study aimed to determine the prevalence of CI and related risk factors in relapsing-remitting MS (RRMS) patients in Turkey. METHODS: The present cross-sectional, multi-center, and nationally representative study included RRMS patients. Sociodemographic characteristics, cognitive functions and additional outcomes were compared between patients with and without CI. RESULTS: The analyses included 487 RRMS patients. According to the BRB-N battery results, CI prevalence was 53.7%. There was a negative significant correlation of BRB-N subtests with age, disease duration, and EDSS and MSNQ-patient rated scores. On the logistic regression analysis, increased age, living in village/rural area, high income level, and high EDSS score were significant increasing risk factors in the development of CI. CONCLUSIONS: This is the first national cognitive data obtained from MS in Turkey, which is a country between Europe and Asia and thus has characteristics of both continents. The similarity of the results of the present study obtained from Turkey to the Western-based data indicates that CI is universal in MS and the main factors affecting CI have not changed.

Feasibility of a 6-Month Yoga Program to Improve the Physical and Psychosocial Status of Persons with Multiple Sclerosis and their Family Members.

CONTEXT: To the best of our knowledge, there has been no study on yoga that includes both persons with multiple sclerosis (MS) and their family members. Because yoga has therapeutic effects in both persons with MS and healthy persons, we hypothesized that it would be an effective method to improve not only the physical and psychosocial status but also the time persons with MS and their family members spend together. OBJECTIVE: To examine the feasibility of a 6-month (long-term) yoga program to improve the physical and psychosocial status of persons with MS and their family members. DESIGN: Uncontrolled clinical trial. SETTING: The protocol was developed at the Department of Neurology, Faculty of Medicine, and School of Physical Therapy and Rehabilitation, Dokuz Eylül University, Izmir, Turkey. PARTICIPANTS: Persons with MS and healthy family members. MAIN OUTCOME MEASURES: Walking, balance, fatigue, health-related quality of life, depression, pain, and kinesiophobia. INTERVENTIONS: Yoga training was given once a week (at least 1h) for 6 months. The same assessors who assessed at baseline also performed the same assessments immediately after the end of the training (i.e., after 6 months). RESULTS: In total, 44 participants (27 persons with MS and 17 healthy family members) participated in the study. Twelve persons with MS and three healthy family members completed the 6-month yoga intervention. The completion rate for persons with MS and healthy subjects was 44.4% and 17.6%, respectively. In persons with MS, the mental dimension of health-related quality of life, walking speed, fatigue, and depression levels significantly improved after the yoga program (p < .05). However, there was no significant change in the self-reported walking impact, balance, pain, physical dimension of health-related quality of life, and kinesiophobia levels in the persons with MS (p > .05). This study suggests that a 6-month yoga program can improve the mental dimension of health-related quality of life, walking speed, fatigue, and depression in the persons with MS. However, the 6-month yoga program does not appear to be a feasible method to increase the time that persons with MS spend together with their family members.

The Turkish validation of the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) battery.

BACKGROUND: Cognitive impairment may be seen in as many as 43-70% of patients with multiple sclerosis (MS) and may be observed in all MS subtypes. The Brief International Cognitive Assessment in Multiple Sclerosis (BICAMS) battery may be used to evaluate cognition status. The purpose of the current study is to validate the BICAMS battery in Turkish. METHODS: Patients with MS attending our clinic between September 2014 and April 2015 were invited to participate. Healthy control participants were matched in terms of age, gender and years of education. RESULTS: One hundred seventy-three MS patients and 153 healthy control participants were enrolled in the study. MS patients performed significantly worse in all trials than the members of the healthy control group. In addition, cognitive dysfunction was identified in 78 of the 173 (45.1%) patients. In the MS with cognitive impairment group, 64 out of 151 (42.4%) subjects were RRMS patients, 12 out of 18 (66.7%) were secondary progressive MS patients, and 2 out of 4 (50%) were primer progressive MS patients. CONCLUSIONS: The BICAMS has been proposed for assessing cognitive impairment in MS patients. This study shows that the battery is suitable for use in Turkey.

Cognitive dysfunction in patients with multiple sclerosis treated with first-line disease-modifying therapy: a multi-center, controlled study using the BICAMS battery.

Multiple sclerosis (MS) can impair cognitive functions even in the early stages. The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) battery is very short and highly sensitive and can be used to evaluate cognitive status in the disease. Several clinical trials have shown beneficial effects of disease-modifying drugs (DMDs) on long-term cognitive measures which may even reduce cognitive deficits in MS patients. Relapsing remitting MS patients using DMDs were enrolled in the study and monitored for 12 months. BICAMS and the Expanded Disability Status Scale were applied to the study group. We evaluated and monitored 161 newly diagnosed cases of definite MS by the end of the trial. 110 patients (68.2%) were female. One hundred and two healthy subjects (female to male ratio 68:34) were enrolled into the study. MS patients were categorized into three DMT groups: IFNB1-a SC, IFNB1-b, and GA. Mean scores of all three cognitive tests (SDMT, BVMT-R, and CVLT-II) were significantly higher in the control group than in the MS patients. The number of cognitively impaired patients decreased from 31.7 to 21.7% on the basis of CVLT (p = 0.024), and 42 (26.1%) to 30 (18.6%) on the basis of BVMT-R at month 12. A significant difference was determined in terms of cognitive status between MS patients using both IFNB and GA and the healthy control group. Ours is the first study to compare IFNB and GA in terms of evaluating cognitive involvement and to use the BICAMS battery in monitoring treatment.
