Fatigue, depression, and health-related quality of life in patients with multiple sclerosis in Isfahan, Iran

The relationship between sleep disorders with patients' demographic-clinical characteristics and quality of life in patients with multiple sclerosis

OBJECTIVES

In this study, the effect of sleep disturbance on the quality of life in MS patients and its relationship between demographic and clinical characteristics of the patients were investigated.

METHODS

67 MS patients and 51 healthy individuals were included in our study. The patient group consisted of 43 women and 24 men. The control group consisted of 32 women and 19 men. Demographic and clinical characteristics of the patients; age, gender, duration of illness, annual number of attacks, treatments, and medical history were recorded and neurological examinations of all patients were performed and disability was determined for each patient with Kurtzke's expanded disability status scale (EDSS). Evaluations were made using demographic data, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Expanded Disability Status Scale (EDSS), Fatigue Severity Scale, Hospital Anxiety and Depression Scale, Berlin Questionnaire and Multiple Sclerosis Quality of Life (MSYK) - 54 Instrument.

RESULTS

We found that the quality of life was significantly impaired in MS patients compared to healthy controls (p < 0.001). And we found that this was related to the presence of progressive MS and chronic fatigue among the clinical features of the patient, sleep-disordered breathing among sleep disorders, poor sleep quality, comorbid anxiety and depression (p = 0.001, p:0.009, p = 0.022, p = 0.007, p < 0.001 and p = 0.001, respectively).

CONCLUSION

All these findings show that sleep disorders in patients with MS are a condition that should be questioned and treated in the follow up of the disease, otherwise it may affect the quality of life of patients negatively.

The Effect of Depression on Health-Related Quality of Life Is Mediated by Fatigue in Persons with Multiple Sclerosis

The interrelations between fatigue, depression and health-related quality of life (HRQoL) in persons with multiple sclerosis (PwMS) are complex, and the directionality of the effects is unclear. To address this gap, the current study used a longitudinal design to assess direct and indirect effects of fatigue and depression on HRQoL in a one-year follow-up survey. A sample of 210 PwMS from the nationwide Swiss MS Registry was used. HRQoL was assessed using the European Quality of Life 5-Dimension 5-Level questionnaire. Path analysis on HRQoL, with fatigue and depression as predictors, was applied. Fatigue was measured by the Modified Fatigue Impact Scale (MFIS), including physical, cognitive and psychosocial subscales, and non-somatic depressive symptomatology was examined with the Beck Depression Inventory-Fast Screen (BDI-FS). Fatigue acted as a fully mediating variable (B = -0.718, SE = 0.253) between non-somatic depressive symptomatology and HRQoL. This indirect effect became apparent in the physical (B = -0.624, SE = 0.250), psychosocial (B = -0.538, SE = 0.256) and cognitive subscales (B = -0.485, SE = 0.192) of fatigue. In contrast, non-somatic depressive symptomatology did not act as a mediator. Our findings provide novel and clinically relevant longitudinal evidence showing that the debilitating effect of non-somatic aspects of depression on HRQoL was fully mediated and therefore explainable via fatigue.

The positive and the negative impacts of spasticity in patients with long-term neurological conditions: an observational study

PURPOSE

To describe the positive and negative impacts of spasticity across different neurological disorders using the Patient Reported Impact of Spasticity Measure (PRISM), deduce any associations between severity of spasticity and its impact, and assess for differences across diagnostic subgroups.

MATERIALS AND METHODS

PRISM, a spasticity-specific quality of life questionnaire validated in patients with spinal cord injuries, was given to 97 follow-up patients attending a spasticity clinic prior to symptom assessment using the REsistance to PAssive movement Scale (REPAS).

RESULTS

Patients described a minor level of positive impact and a marked negative impact in the domains of "Psychological Agitation," "Daily Activities," "Need for Assistance/Positioning" and "Social Avoidance/Anxiety." Spasticity severity was, in general, a poor predictor of perceived impact, although severity and localisation of spasticity was modestly correlated with "Need for Assistance/Positioning" and "Social Embarrassment" levels. Despite comparable levels of spasticity severity, people with MS expressed a more substantial impact across some PRISM domains than did patients in other groups.

CONCLUSION

PRISM can be useful to assess the impact of spasticity in various neurological conditions although further validation studies are needed.Implications for RehabilitationThe localisation of spasticity in both legs or the right arm can produce a significant impact on 'Need for Assistance/Positioning' and 'Social Embarrassment'.People with MS may experience a greater impact of spasticity than those with other neurological conditions, particularly in the domains of Social Avoidance/Anxiety and Psychological Agitation.Coexisting factors such as anxiety, depression, fatigue and pain should be investigated together with spasticity.PRISM can assist in goal setting and treatment of people with spasticity secondary to different neurological conditions.

Factors affecting MS patients' health-related quality of life and measurement challenges in Lebanon and the MENA region

Background

In the Middle East and North Africa (MENA) region, few studies explored the quality of life of multiple sclerosis patients and the factors affecting it.

Objective

The objective of this study was to explore studies on multiple sclerosis quality of life in the MENA area through a comprehensive literature review. To validate the Multiple sclerosis international Quality of Life (MusiQoL) and Modified Fatigue Impact Scale (MFIS) in Arabic, and investigate the impact of sociodemographic and clinical variables of Lebanese multiple sclerosis patients on quality of life.

Methods

As part of an ongoing observational prospective research study, data from 663 stable multiple sclerosis patients were analysed.

Results

In Lebanese multiple sclerosis patients, the Arabic MusiQoL and MFIS seem to be accurate and valid tools with high reliability coefficients and confirmatory factor analytic indices. Variables such as age and disease type predicted multiple sclerosis quality of life, yet were significantly affected by psychosocial fatigue. The influence of sociodemographic and clinical variables on quality of life dimensions varied. Being a woman with multiple sclerosis, receiving medications and experiencing physical fatigue worsens the psychological wellbeing quality of life dimension.

Conclusion

Several sociodemographic and clinical variables predicted the health-related quality of life dimensions of multiple sclerosis patients in MENA. Further in-depth investigation to guide more targeted clinical management is recommended. We encourage using validated multidimensional tools to measure quality of life in MENA such as the Arabic MusiQoL.

An analysis of the relationship of character strengths and quality of life in persons with multiple sclerosis

PURPOSE

To examine the relationship of character strengths and quality of life (QOL) in persons with multiple sclerosis (MS). Specifically, this study examined the relationship of the 24 character strengths in Peterson and Seligman's model with QOL and three negative effects of MS (disability, fatigue, and depression). It also investigated whether the three negative effects of MS mediate the relationship of each of the character strengths and QOL.

METHODS

Six hundred and twenty-four individuals with MS completed an online survey measuring character strengths, QOL, as measured by the Leeds Multiple Sclerosis Quality of Life Scale, disability, fatigue, and depression. SPSS was used to complete the correlational analysis, and Hayes' PROCESS macro for SPSS was used to conduct the mediation analyses.

RESULTS

The strengths endorsed most frequently by the participants were honesty, kindness, and fairness. The least-endorsed strengths were self-regulation, zest, and spirituality. The strengths with the strongest association with QOL were zest, hope, and gratitude. Disability was not found to mediate any of the relationships between character strengths and QOL. Many of the character strengths were associated with QOL both directly and indirectly through fatigue and depression.

CONCLUSIONS

Many of the character strengths in the Peterson and Seligman model enhance QOL in persons with MS, both directly and through their influence on negative effects of MS. The results provide support for the development of character strengths interventions to impact QOL, both directly and indirectly through improvements to MS-related symptoms such as fatigue and depression.

Clinical and demographic features in Iranian multiple sclerosis patients: a systematic review and meta-analysis

Aim: This study was conducted to determine the clinical and demographic features in Iranian multiple sclerosis (MS) patients including clinical courses, positive MS family history, disability and age of disease onset. Materials & methods: All stages of the study were reported according to the PRISMA guidelines. A systematic review of published literature in Persian and English journals with a comprehensive search was conducted on English international databases including Scopus, PubMed/Medline, Cochrane Library, Science Direct, Web of Science, Embase, PsycINFO, as well as the Google Scholar search engine and national databases. Results: The prevalence of clinical courses of relapsing remitting, primary progressive, secondary progressive and relapsing progressive in Iranian patients with MS was 77.1% (95% CI: 72.2–81.3), 6.2% (95% CI: 4.1–9.2), 9.5% (95% CI: 6.8–13.1) and 0.4% (95% CI: 0.2–0.8), respectively. Positive family history of MS in Iranian MS patients was 8.9% (95% CI: 6.9–11.4). The mean age of disease onset was 28.9 years (95% CI: 27.8–30.1). Conclusion: The results of this meta-analysis in an Iranian population can provide useful information for neurologists and healthcare.

Biomedical Variables and Adaptation to Disease and Health-Related Quality of Life in Polish Patients with MS

The aim of this research was to assess the level of adaptation to multiple sclerosis (Sclerosis multiplex; MS) and health-related quality of life (HRQoL) of the study population as well as to determine the relationship between biomedical factors related to the course of multiple sclerosis, adaptation to the disease, and HRQoL. Analysis of medical records, clinical and psychological interviews, the Extended Disability Status Scale (EDSS), Guy’s Neurological Disability Scale (GNDS), the Acceptance of Illness Scale (AIS), and the Multiple Sclerosis Impact Scale 29 (MSIS-29) were collected from 137 patients with MS. It was found that there was a relation between motor impairment, neurological disability, adaptation to illness, and HRQoL; it was also found that there were negative correlations between adaptation to illness and the severity of lower-limb disability, fatigue, mood disorders, other problems related to MS, and upper-limb disability. Of all the symptoms, lower-limb disability, fatigue, and mood disorders had the strongest relation with adaptation. All of the analysed symptoms were found to correlate with HRQoL. Of all the symptoms, HRQoL was most affected by lower- and upper-limb disability, fatigue, other MS problems, and mood disorders.

Depression in Multiple Sclerosis: Epidemiology, Aetiology, Diagnosis and Treatment

Depressive disorders are common in patients with multiple sclerosis, influencing their quality of life and adherence to treatments, as well as becoming more frequent with the progression of the disease and in the secondary progressive form of multiple sclerosis. Patients with multiple sclerosis often experience a typical cluster of symptoms in association with depression, such as fatigue, pain and cognitive impairment. However, the pathogenesis of multiple sclerosis-related depression remains partially unclear, even though genetic, immune-inflammatory and psychosocial factors might be seen to play a role, in addition to the brain structural alterations documented by magnetic resonance imaging studies. The high incidence and burden of depression in people affected with multiple sclerosis are matters of crucial importance. Despite such importance, the efficacy of pharmacologic treatments has been poorly studied and, for the most part, the access to non-pharmacological treatments is partially dependent on the local health system availability. It has been determined that interferon-beta and glatiramer acetate do not cause depressive symptoms; however, no definitive data in this regard are avaible for the newer disease-modifyng medications. In this review, we discuss the diagnosis, prevalence, pathogenesis, clinical aspects, magnetic resonance imaging findings and treatments available in patients experiencing multiple sclerosis-related depression.

Is the association between health-related quality of life and fatigue mediated by depression in patients with multiple sclerosis? A Spanish cross-sectional study

OBJECTIVES

To determine the mediating effects of depression on health-related quality of life and fatigue in individuals with multiple sclerosis (MS).

DESIGN

A cross-sectional study.

SETTING

Tertiary urban hospital.

PARTICIPANTS

One hundred and eight patients (54% women) with MS participated in this study.

OUTCOME MEASURES

Demographic and clinical data (weight, height, medication and neurological impairment), fatigue (Fatigue Impact Scale), depression (Beck Depression Inventory-II) and health-related quality of life (Short-Form Health Survey 36) were collected.

RESULTS

Fatigue was significantly associated with bodily pain, physical function, mental health and depression. Depression was associated with bodily pain and mental health. The path analysis found direct effects from physical function, bodily pain and depression to fatigue (all, P<0.01). The path model analysis revealed that depression exerted a mediator effect from bodily pain to fatigue (B=-0.04, P<0.01), and from mental health to fatigue (B=-0.16, P<0.01). The amount of fatigue explained by all predictors in the path model was 37%.

CONCLUSIONS

This study found that depression mediates the relationship between some health-related quality of life domains and fatigue in people with MS. Future longitudinal studies focusing on proper management of depressive symptoms in individuals with MS will help determine the clinical implications of these findings.

Determinants of health-related quality of life in Iranian adults: evidence from a cross-sectional study

OBJECTIVES

This study aimed to measure the level and determinants of health-related quality of life (HRQoL) in adults in Kermanshah, a city in the western region of Iran.

METHODS

Convenience sampling was employed to obtain a sample of 998 adults aged 18 years and older (646 males and 352 females) in the city of Kermanshah. A 2-part self-administered questionnaire was used to collect data over the period between March 1 and May 30, 2017. The first part was designed to collect information on socio-demographic characteristics, socioeconomic status, and lifestyle factors (10 items). The second part consisted of the EuroQoL 5-dimensions (EQ-5D) EuroQoL-3-level and the EuroQoL visual analog scale (EQ-VAS) questions. A multiple linear regression model was used to determine the factors associated with the EQ-5D index and EQ-VAS score among study participants.

RESULTS

The mean values for the EQ-5D index and the EQ-VAS score were 0.74 (standard deviation [SD], 0.19) and 80.9 (SD, 16.5), respectively. The highest percentage of self-reported problems (‘some’ and ‘severe’ problems) across the 5 dimensions of the EQ-5D index were associated with the dimensions of anxiety/depression (35.3%) and pain/discomfort (32.9%). The percentage of self-reported problems for the dimensions of usual activities, mobility, and self-care were 19.0, 12.8, and 8.9%, respectively. Our regression analyses indicated that there were statistically significant positive associations between being physically active, monthly household income per capita, and post-secondary education and the EQ-5D index and EQ-VAS score. In contrast, negative associations were found between older age, being married, having a chronic disease, and smoking and the EQ-5D index and EQ-VAS score. A negative association was also found between being uninsured and the EQ-5D index.

CONCLUSIONS

Our findings suggest that interventions aiming to improve physical activity, to prevent chronic diseases, and to reduce the smoking rate among adults living in the city of Kermanshah may improve their HRQoL.

The impact of disease characteristics on multiple sclerosis patients' quality of life

OBJECTIVES

The aim of this study was to assess the quality of life (QoL) of patients with multiple sclerosis (MS), and to investigate the effects of characteristics of MS such as disease course, severity, and relapses on patients' QoL.

METHODS

This was a cross-sectional study, in which 171 patients were enrolled. Health-related QoL was assessed using the Persian version of the Multiple Sclerosis Quality of Life-54 questionnaire. To measure patients' disability status, we used the Expanded Disability Status Scale. Other variables included in the study were disease course and relapses of the disease.

RESULTS

The average scores for patients' physical and mental QoL were 60.9±22.3 and 59.5±21.4, respectively. In a bivariate analysis, disease course, severity of the disease, and relapses were significantly associated with the physical and mental health composite scores. In a hierarchal regression analysis, disease course, severity of the disease, and relapses were responsible for 38 and 16% of the variance in physical and mental QoL, respectively. It was also observed that relapses were a strong predictor of both physical and mental QoL.

CONCLUSIONS

Our results showed that disease characteristics significantly affected both dimensions of QoL. It is therefore suggested that health care providers should be aware of these characteristics of MS to more successfully improve MS patients' QoL.

Effects of Yoga on Physiological Indices, Anxiety and Social Functioning in Multiple Sclerosis Patients: A Randomized Trial

INTRODUCTION

Multiple sclerosis (MS) as a chronic disease could affect patients' various domains of life.

AIM

This study was conducted to study the effect of yoga on the physiological indices, anxiety and social functioning of patients with MS in southwest, Iran.

MATERIALS AND METHODS

In this clinical trial study, 60 MS patients were enrolled according to inclusion criteria and randomly assigned to two groups of 30 each. Prior to and after intervention, the patients' vital signs were measured. For case group yoga exercises were performed three sessions a week for 12 weeks while control group performed no exercise. The data were gathered by questionnaire and analysed by descriptive and analytical statistics in SPSS.

RESULTS

Prior to intervention, there was no significant difference in fatigue severity and pain between the two groups but the mean fatigue severity and pain in case group decreased compared to the control group after the intervention. Prior to intervention, there was no significant difference in mean physiological indices between the two groups but the mean physiological indices in case group decreased significantly after the intervention (p<0.05).

CONCLUSION

Yoga is likely to increase self-efficacy of MS patients through enhancing physical activity, increasing the strength of lower limbs and balance, and decreasing fatigue and pain, and finally to promote social functioning and to relieve stress and anxiety in these patients.

The effects of fatigue, depression and the level of disability on the health-related quality of life of glatiramer acetate-treated relapsing-remitting patients with multiple sclerosis in Hungary

BACKGROUND

The common symptoms of multiple sclerosis are fatigue, depression, cognitive dysfunction, pain and sexual dysfunction, which influence the health-related quality of life of the patients.

OBJECTIVE

We aimed to determine the correlations between the health-related quality of life, the level of disability, fatigue and depression in glatiramer acetate-treated patients with multiple sclerosis in Hungary.

METHODS

The Hungarian versions of the Multiple Sclerosis Quality of Life-54, Fatigue Impact Scale and Beck Depression Inventory questionnaires were completed by 428 relapsing-remitting multiple sclerosis patients treated with glatiramer acetate from 19 Hungarian centers.

RESULTS

The prevalence of fatigue was found to be 62.4%. The prevalence of depression was lower (13.4%) than that described in previous studies (36-54%) among patients with multiple sclerosis. Significant differences in the health-related quality of life were found between fatigued and non-fatigued patients. The level of disability, fatigue, depression and the duration of the disease correlated significantly with the quality of life. However, linear regression analysis indicated that the quality of life was predicted by the level of disability, depression, social and cognitive fatigue, but not by physical fatigue.

CONCLUSIONS

Decreasing the disease activity in multiple sclerosis with immunomodulatory therapy, together with improvements of the diagnostics and treatment of the accompanying depression and fatigue are of high priority to improve the health-related quality of life of patients with multiple sclerosis.

Predictors of Incident Seizure in Systemic Lupus Erythematosus

OBJECTIVE

The risk factors for incident seizures in systemic lupus erythematosus (SLE) were prospectively determined in a cohort study.

METHODS

A total of 2203 patients with SLE followed longitudinally in the Hopkins Lupus Cohort were analyzed. Demographic variables, clinical manifestations, laboratory tests, and SLE disease activity were recorded at each quarterly visit. Adjusted estimates of association of risk factors for onset of seizure were derived using pooled logistic regression. We examined incident seizures in 3 ways: at the time of diagnosis, more than 45 days after the diagnosis of SLE, and after cohort entry.

RESULTS

Of 2203 patients with no history of seizure prior to SLE diagnosis, 157 (7.13%) had the first seizure occurrence at the time of (37 patients, 1.68%) or after diagnosis (120 patients, 5.45%) of SLE. The risk of seizure occurring around the time of SLE diagnosis was higher in patients with a history of malar rash (p = 0.002), proteinuria (p = 0.004), and psychosis (p < 0.001). Multivariable analysis of the first seizure occurring after the diagnosis of SLE showed that history of low C3 (p = 0.0078), psychosis (p < 0.0001), cranial or peripheral neuropathy (p = 0.0043), anti-Sm antibody (p = 0.0551), renal involvement (p = 0.0177), and current corticosteroid dose (p < 0.0001) were independently associated with a higher incidence of seizure. Disease activity was not predictive after adjusting for corticosteroids.

CONCLUSION

Risk of seizure after diagnosis of SLE is increased in those patients with prior psychosis, neuropathy, proteinuria, anti-Sm, low C3, and use of corticosteroids.

Fatigue, Sleep Quality, and Disability in Relation to Quality of Life in Multiple Sclerosis

BACKGROUND

Quality of life (QOL) is impaired in multiple sclerosis (MS) in part due to physical disability. MS-associated fatigue and poor sleep are common and treatable features of MS that affect QOL. We assessed the association between fatigue, sleep quality, and QOL in people with MS.

METHODS

Cross-sectional data were collected from 217 patients with MS. Health-related QOL (MS Quality of Life-54), fatigue (Fatigue Severity Scale [FSS]), and sleep quality (Pittsburgh Sleep Quality Inventory [PSQI]) were assessed. Expanded Disability Status Scale scores were also provided by a qualified neurologist.

RESULTS

The mean ± SD age of the 217 patients was 32.6 ± 8.6 years, and 79% were female. One hundred fifty-two patients (70.0%) were classified as poor sleepers based on PSQI scores; 122 (56.2%) had significant fatigue based on FSS results. The mean ± SE physical (PCS) and mental (MCS) health composite scores of the MSQOL-54 were 40.12 ± 1.27 and 43.81 ± 1.61, respectively. There was a strong statistically significant positive correlation between PCS scores and MCS (r = 0.58), FSS (r = 0.49), and PSQI (r = 0.52) scores. MCS scores were strongly correlated with FSS (r = 0.53) and PSQI (r = 0.35) scores. Age exhibited statistically significant negative correlations with PCS (r = -0.21) and MCS (r = -0.58) scores, and was statistically significantly correlated with FSS (r = 0.23) and PSQI (r = 0.21) scores. Expanded Disability Status Scale scores were strongly correlated with FSS scores.

CONCLUSIONS

These findings support screening of fatigue severity and sleep quality and their effects on QOL.

A systematic review of the incidence and prevalence of comorbidity in multiple sclerosis: overview

Background:

Comorbidity is an area of increasing interest in multiple sclerosis (MS).

Objective:

The objective of this review is to estimate the incidence and prevalence of comorbidity in people with MS and assess the quality of included studies.

Methods:

We searched the PubMed, SCOPUS, EMBASE and Web of Knowledge databases, conference proceedings, and reference lists of retrieved articles. Two reviewers independently screened abstracts. One reviewer abstracted data using a standardized form and the abstraction was verified by a second reviewer. We assessed study quality using a standardized approach. We quantitatively assessed population-based studies using the I² statistic, and conducted random-effects meta-analyses.

Results:

We included 249 articles. Study designs were variable with respect to source populations, case definitions, methods of ascertainment and approaches to reporting findings. Prevalence was reported more frequently than incidence; estimates for prevalence and incidence varied substantially for all conditions. Heterogeneity was high.

Conclusion:

This review highlights substantial gaps in the epidemiological knowledge of comorbidity in MS worldwide. Little is known about comorbidity in Central or South America, Asia or Africa. Findings in North America and Europe are inconsistent. Future studies should report age-, sex- and ethnicity-specific estimates of incidence and prevalence, and standardize findings to a common population.

The incidence and prevalence of psychiatric disorders in multiple sclerosis: a systematic review

BACKGROUND

Psychiatric comorbidity is associated with lower quality of life, more fatigue, and reduced adherence to disease-modifying therapy in multiple sclerosis (MS).

OBJECTIVES

The objectives of this review are to estimate the incidence and prevalence of selected comorbid psychiatric disorders in MS and evaluate the quality of included studies.

METHODS

We searched the PubMed, PsychInfo, SCOPUS, and Web of Knowledge databases and reference lists of retrieved articles. Abstracts were screened for relevance by two independent reviewers, followed by full-text review. Data were abstracted by one reviewer, and verified by a second reviewer. Study quality was evaluated using a standardized tool. For population-based studies we assessed heterogeneity quantitatively using the I² statistic, and conducted meta-analyses.

RESULTS

We included 118 studies in this review. Among population-based studies, the prevalence of anxiety was 21.9% (95% CI: 8.76%-35.0%), while it was 14.8% for alcohol abuse, 5.83% for bipolar disorder, 23.7% (95% CI: 17.4%-30.0%) for depression, 2.5% for substance abuse, and 4.3% (95% CI: 0%-10.3%) for psychosis.

CONCLUSION

This review confirms that psychiatric comorbidity, particularly depression and anxiety, is common in MS. However, the incidence of psychiatric comorbidity remains understudied. Future comparisons across studies would be enhanced by developing a consistent approach to measuring psychiatric comorbidity, and reporting of age-, sex-, and ethnicity-specific estimates.

A systematic review and meta-analysis of strength training in individuals with multiple sclerosis or Parkinson disease

Strength training has, in recent years, been shown to be beneficial for people with Parkinson disease and multiple sclerosis. Consensus regarding its utility for these disorders nevertheless remains contentious among healthcare professionals. Greater clarity is required, especially in regards to the type and magnitude of effects as well as the response differences to strength training between individuals with Parkinson disease or multiple sclerosis. This study examines the effects, magnitude of those effects, and response differences to strength training between patients with Parkinson disease or multiple sclerosis. A comprehensive search of electronic databases including Physiotherapy Evidence Database scale, PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and CINAHL was conducted from inception to July 2014. English articles investigating the effect of strength training for individuals with neurodegenerative disorders were selected. Strength training trials that met the inclusion criteria were found for individuals with Parkinson disease or multiple sclerosis. Individuals with Parkinson disease or multiple sclerosis were included in the study. Strength training interventions included traditional (free weights/machine exercises) and nontraditional programs (eccentric cycling). Included articles were critically appraised using the Physiotherapy Evidence Database scale. Of the 507 articles retrieved, only 20 articles met the inclusion criteria. Of these, 14 were randomized and 6 were nonrandomized controlled articles in Parkinson disease or multiple sclerosis. Six randomized and 2 nonrandomized controlled articles originated from 3 trials and were subsequently pooled for systematic analysis. Strength training was found to significantly improve muscle strength in people with Parkinson disease (15%-83.2%) and multiple sclerosis (4.5%-36%). Significant improvements in mobility (11.4%) and disease progression were also reported in people with Parkinson disease after strength training. Furthermore, significant improvements in fatigue (8.2%), functional capacity (21.5%), quality of life (8.3%), power (17.6%), and electromyography activity (24.4%) were found in individuals with multiple sclerosis after strength training. The limitations of the study were the heterogeneity of interventions and study outcomes in Parkinson disease and multiple sclerosis trials. Strength training is useful for increasing muscle strength in Parkinson disease and to a lesser extent multiple sclerosis.

Prevalence of fatigue in patients with multiple sclerosis and its effect on the quality of life

Objective:

This prospective study was carried out to observe the prevalence of fatigue in patients with multiple sclerosis (MS) and its effect on quality-of-life (QoL).

Study Design and Setting:

Prospective observational study in a University Tertiary Research Hospital in India.

Patients and Methods:

A total of 31 patients (25 females) with definite MS according to McDonald's criteria presented in out-patient/admitted in the Department of Neurology (between February 2010 and December 2011) were included in the study. Disease severity was evaluated using the Kurtzke's expanded disability status scale (EDSS). Fatigue was assessed using Krupp's fatigue severity scale (FSS). QoL was assessed by the World Health Organization QoL-BREF questionnaire.

Results:

The mean age of patients was 30.1 ± 9.1 years. The mean age at first symptom was 25.23 ± 6.4 years. The mean number of relapses was 4.7 ± 3.6 in the patients. The mean duration of illness was 4.9 ± 4.4 years. The mean EDSS score was 3.5 ± 2.2. Mean fatigue score was 38.7 ± 18.5 (cut-off value 36 in FSS). The prevalence of fatigue in patients with MS was 58.1% (18/31). MS patients with fatigue were significantly more impaired (P < 0.05) on all QoL domains (i.e., physical, psychosocial, social, and environment) than MS patients without fatigue.

Conclusion:

Prevalence of fatigue was found to be high in the MS patients in the study. All four domains of QoL were significantly more impaired in the group with fatigue than in those without fatigue.

Co-occurring depression and pain in multiple sclerosis

Depression and pain are highly prevalent among individuals with multiple sclerosis, and they often co-occur. The purpose of this article is to summarize the literature and theory related to the comorbidity of pain and depression and describe how their presence can impact individuals with multiple sclerosis. Additionally, the article discusses how existing treatments of pain and depression could be adapted to address shared mechanisms and overcome barriers to treatment utilization.
