Conversion to secondary progressive multiple sclerosis: Multistakeholder experiences and needs in Italy. PLoS One 2020; 15:e0228587. [PMID: 32053608 PMCID: PMC7018010 DOI: 10.1371/journal.pone.0228587] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Accepted: 01/17/2020] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Conversion to secondary progressive multiple sclerosis (SPMS) is associated with a relatively poor prognosis, and SPMS is responsible for the majority of the social and economic costs associated with MS. Managing the Transition to SPMS (ManTra) is a mixed methods project conducted in Italy and Germany aimed to set up a user-led resource to empower and improve the quality of life of newly diagnosed SPMS patients. AIMS To assess the experiences and the needs of Italian people who recently converted to SPMS, patient significant others (SOs), neurologists and other health professionals (HPs). METHODS We conducted 15 personal semistructured interviews (PSIs) with SPMS patients who transitioned up to five years, and three focus group meetings (FGMs), one of SPMS SOs, one of neurologists, and one of other HPs. Participants were purposely selected from the three geographic areas of Italy, and varied in terms of gender, education and (for patients) disease severity. PSIs and FGMs were audiorecorded, transcribed and analyzed by two researchers using the framework analysis. RESULTS One hundred sub-categories were identified, grouped into 13 categories and four themes: 'awareness of the transition', 'communication of the transition', 'dealing with symptoms worsening', and 'needs'. The major unmet needs were collected in four dimensions 'organization and management; 'empowerment training'; 'information'; and 'policies'. CONCLUSIONS Two are the main findings: first, the widespread lack of awareness around the transition; second, the need to improve the quality of the care pathway in the Italian context. It was particularly stressed the need for a holistic and multidisciplinary approach (with patients and SOs as members of the team), the development of an ad hoc plan of follow up visits with easy access to MS specialists' consultation/treatment; specialized training for each stakeholders; more information on SPMS, daily management and changes at policy level.

The Impact of Coconut Oil and Epigallocatechin Gallate on the Levels of IL-6, Anxiety and Disability in Multiple Sclerosis Patients. Nutrients 2020; 12:nu12020305. [PMID: 31979305 PMCID: PMC7070654 DOI: 10.3390/nu12020305] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Revised: 01/15/2020] [Accepted: 01/19/2020] [Indexed: 02/07/2023] Open
Abstract
Background: Due to the inflammatory nature of multiple sclerosis (MS), interleukin 6 (IL-6) is high in blood levels, and it also increases the levels of anxiety related to functional disability. Epigallocatechin gallate (EGCG) decreases IL-6, which could be enhanced by the anti-inflammatory effect of high ketone bodies after administering coconut oil (both of which are an anxiolytic). Therefore, the aim of this study was to assess the impact of coconut oil and EGCG on the levels of IL-6, anxiety and functional disability in patients with MS. Methods: A pilot study was conducted for four months with 51 MS patients who were randomly divided into an intervention group and a control group. The intervention group received 800 mg of EGCG and 60 mL of coconut oil, and the control group was prescribed a placebo. Both groups followed the same isocaloric Mediterranean diet. State and trait anxiety were determined before and after the study by means of the State-Trait Anxiety Inventory (STAI). In addition, IL-6 in serum was measured using the ELISA technique and functional capacity was determined with the Expanded Disability Status Scale (EDSS) and the body mass index (BMI). Results: State anxiety and functional capacity decreased in the intervention group and IL-6 decreased in both groups. Conclusions: EGCG and coconut oil improve state anxiety and functional capacity. In addition, a decrease in IL-6 is observed in patients with MS, possibly due to the antioxidant capacity of the Mediterranean diet and its impact on improving BMI.

Influence of different rehabilitative aerobic exercise programs on (anti-) inflammatory immune signalling, cognitive and functional capacity in persons with MS - study protocol of a randomized controlled trial. BMC Neurol 2019; 19:37. [PMID: 30849952 PMCID: PMC6407211 DOI: 10.1186/s12883-019-1267-9] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Accepted: 03/04/2019] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Studies have shown positive effects of therapeutic exercise on motor- and cognitive function as well as on psychosocial outcomes in persons with multiple sclerosis (MS). A reduction of inflammatory stress through physical exercise has been suspected as one key mechanism, mediating the positive effects of exercise in the context of MS. The primary objective of this trial is to investigate the acute and chronic effects of different exercise modalities on (anti-)inflammatory immune signalling as well as on cognitive and functional capacity in persons with MS. METHODS A two armed single-blind randomized controlled design will investigate 72 persons with relapsing remitting or secondary progressive MS (EDSS 3.0-6.0), during 3 weeks of inpatient rehabilitation. Participants will be randomized into either a high-intensity interval training (HIIT) or a moderate continuous training group; the latter represents the local standard therapy (ST). Both groups will exercise 3x per week. The HIIT group will perform 5 × 1.5-min high-intensive exercise bouts at 95-100% of their maximum heart rate (HRmax) followed by active breaks of unloaded pedalling (60% HRmax) for 2 min. In contrast, the ST group will exercise for 24 min continuously at 65% of HRmax. The proportion of circulating regulatory T-cells will be measured as primary outcome. Secondary outcomes comprise numbers and proportions of further immune cells including Th17-cells, soluble factors ((anti-) inflammatory cytokines, tryptophan metabolites), endurance capacity, cognitive performance, processing skills for activities of daily living, fatigue, depression and healthcare-related quality of life. Outcomes will be assessed before (T0) and after (T3) the 3-week exercise intervention program. Blood samples of T0 will be taken immediately before the first exercise session. Additionally, blood samples for the soluble factors will be collected immediately after (T1) and three hours (T2) after the first exercise session of each group. DISCUSSION This study will be the first to investigate both acute and chronic effects of aerobic exercise on immune function and disease associated biomarkers in persons with MS. Combining biological analyses with cognitive and functional capacity assessments may contribute to a better understanding of responses to rehabilitative training, needed to improve exercise recommendations for persons with MS. TRIAL REGISTRATION This trial was prospectively registered at ClinicalTrials.gov ( NCT03652519 ; 29 August 2018).

Abstract
OBJECTIVES Transitioning to secondary progressive multiple sclerosis (SPMS) is demanding for both patients and healthcare professionals. The particular challenges and the ways patients cope are poorly understood. The present study examines what challenges people face when diagnosed with SPMS by exploring experiences of people who have transitioned recently (up to 5 years). DESIGN Semistructured qualitative interviews at two time points a year apart. Interviews were analysed using inductive thematic analysis. SETTING UK. PARTICIPANTS We interviewed 21 people at baseline and 17 participated in the follow-up interviews. RESULTS The majority of participants reported expecting to transition to SPMS, and the diagnosis did not make much difference to them. Participants described increasing emotional and physical challenges after transitioning to SPMS and between the first and second interviews. Planning, using distractions and maintaining social roles helped participants cope with the increased challenges. The same coping strategies were used between the two interviews. Participants felt there was not much left to do regarding the management of their symptoms. A key theme was the sense of abandonment from healthcare services after transitioning to SPMS. CONCLUSIONS After transitioning to SPMS, people are faced with multiple challenges. Participants described a lack of directions for symptoms management and lack of support from the healthcare system. An integrated multidisciplinary healthcare approach is crucial at the progressive stage of the disease to alleviate feelings of helplessness and promote symptom management.

Determinants of quality of life in relapsing-remitting and progressive multiple sclerosis. Mult Scler Relat Disord 2019; 30:33-37. [PMID: 30735970 DOI: 10.1016/j.msard.2019.01.049] [Citation(s) in RCA: 55] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 01/06/2019] [Accepted: 01/29/2019] [Indexed: 12/25/2022]
Abstract
BACKGROUND Numerous factors can affect multiple sclerosis (MS) patients' quality of life (QoL). We investigated how physical impairment, upper extremity function, cognitive impairment, cognitive reserve, symptoms of psychological distress, depression, fatigue as well as age and disease duration contribute to patient-reported measures of QoL in relapse-remitting MS (RRMS) and progressive MS (PMS). METHODS 39 patients with RRMS and 16 patients with PMS were evaluated for physical impairment (EDSS assessed by a neurologist), upper extremity function (9-hole peg test), cognitive deficits (broad neuropsychological test battery), cognitive reserves (highest obtained degree of education and vocabulary), symptoms of psychological distress (Symptom Checklist-90-R), depression (Beck Depression Inventory) and fatigue (Fatigue Scale for Motor and Cognitive Functions). The effects of these variables on QoL, as measured with the EQ-5D-3L, were tested with a multivariate analysis of variance. RESULTS Degree of education, MS disease type, disease duration, BDI and SCL-90-R-scores affected significantly the EQ-5D index. Post-hoc analysis revealed that patients with university education, RRMS, shorter disease duration as well as less depression and psychological distress symptoms had significantly higher EQ-5D indices. No significant effects were observed for measures of physical disability, cognitive impairment or fatigue. CONCLUSIONS Depression and psychological distress symptoms are among the factors with the most essential impact on subjective well-being in MS patients. Since they can be targeted by both psychopharmacological and psychotherapeutic treatment, focusing on mental comorbidity could substantially increase QoL in MS.

Abstract
Using fMRI during a face encoding (FE) task, we investigated the behavioral and fMRI correlates of FE in patients with relapse-onset multiple sclerosis (MS) at different stages of the disease and their relation with attentive-executive performance and structural MRI measures of disease-related damage. A fMRI FE task was administered to 75 MS patients (11 clinically isolated syndromes - CIS, 40 relapsing-remitting - RRMS - and 24 secondary progressive - SPMS) and 22 healthy controls (HC). fMRI activity during the face encoding condition was correlated with behavioral, clinical, neuropsychological and structural MRI variables. All study subjects activated brain regions belonging to face perception and encoding network, and deactivated areas of the default-mode network. Compared to HC, MS patients had the concomitant presence of areas of increased and decreased activations as well as increased and decreased deactivations. Compared to HC or RRMS, CIS patients experienced an increased recruitment of posterior-visual areas. Thalami, para-hippocampal gyri and right anterior cingulum were more activated in RRMS vs CIS or SPMS patients, while an increased recruitment of frontal areas was observed in SPMS vs RRMS. Areas of abnormal activations were significantly correlated with clinical, cognitive-behavioral and structural MRI measures. Abnormalities of FE network occur in MS and vary across disease clinical phenotypes. Early in the disease, an increased recruitment of areas typically devoted to face perception and encoding occurs. In SPMS patients, abnormal functional recruitment of frontal lobe areas might contribute to the severity of clinical manifestations.

Relationship between Social Cognition and traditional cognitive impairment in Progressive Multiple Sclerosis and possible implicated neuroanatomical regions. Mult Scler Relat Disord 2018; 20:122-128. [PMID: 29414284 DOI: 10.1016/j.msard.2018.01.013] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2017] [Revised: 11/16/2017] [Accepted: 01/16/2018] [Indexed: 01/12/2023]
Abstract
BACKGROUND Cognitive impairment is a relevant contributor of the medical and social burden in Progressive MS. Social Cognition, the neurocognitive processes underlying social interaction, has been explored mainly in European and North American cohorts, influencing social aspects of quality of life (QOL) of early MS patients and families. Few studies have studied Social Cognition in Progressive MS and the literature on its neuroanatomical bases or brain atrophy measurements is still scarce. OBJECTIVES To explore the relationship between Social Cognition performance and its correlations with traditional cognitive domains, brain atrophy and QOL in primary and secondary Progressive MS patients. METHODS Cross-sectional analysis including: mini-Social-Cognition-and-Emotional-Assessment (mini-SEA), neuropsychological battery, disability, depression, fatigue, QOL, and brain volume. RESULTS Forty-three MS patients, 23 primary and 20 secondary Progressive, 65% women, mean age and disease duration of 57.2 and 15.7 years, respectively, with high levels of disability (median EDSS 6.0) and a widespread impairment in traditional domains (mostly episodic verbal/visual and working memories) were assessed. The Mini-SEA score was correlated with executive functions (cognitive shifts Rho:0.55; p = 0.001) analyzing the whole group, and with visual episodic memory (Rho:0.58, p = 0.009) in the primary Progressive MS group. Mini-SEA score was also correlated with total normalized grey matter volume (Rho:0.48; p = 0.004). Particularly, atrophy within bilateral cortical regions of orbitofrontal, insula and cerebellum, and right regions of fusiform gyrus and precuneus were significantly associated with higher Social Cognition impairment. In this cohort, QOL was not correlated with Social Cognition, but with EDSS, fatigue and depression. CONCLUSIONS In Progressive MS, Social Cognition is directly correlated with traditional cognitive domains such as executive function and episodic memory. It is also associated with global grey matter atrophy and regional atrophy within associative visual and executive cortical areas, but no correlations with QOL were found in this cohort. These findings may contribute to the understanding of the pathological bases behind Social Cognition in Progressive MS.

Limbic system damage in MS: MRI assessment and correlations with clinical testing. PLoS One 2017; 12:e0187915.

Abstract
Volume loss in some limbic region structures has been observed in multiple sclerosis (MS) patients. However, in vivo evaluation of existing tissue cellular microstructure integrity has received less attention. The goal of studies reported here was to quantitatively assess loss of limbic system volumes and tissue integrity, and to evaluate associations of these measures with cognitive and physical dysfunction in MS patients. Thirty-one healthy controls (HC) and 80 MS patients, including 32 relapsing remitting (RRMS), 32 secondary progressive (SPMS) and 16 primary progressive (PPMS), participated in this study. Tissue cellular integrity was evaluated by means of recently introduced tissue-specific parameter R2t* that was calculated from multi-gradient-echo MRI signals using a recently developed method that separates R2t* from BOLD (blood oxygen level dependent) contributions to GRE signal decay rate constant (R2*), and accounting for physiological fluctuations and artifacts from background gradients. Volumes in limbic system regions, normalized to skull size (NV), were measured from standard MPRAGE images. MS patients had lower R2t* and smaller normalized volumes in the hippocampus, amygdala, and several other limbic system regions, compared to HC. Alterations in R2t* of several limbic system regions correlated with clinical and neurocognitive test scores in MS patients. In contrast, smaller normalized volumes in MS were only correlated with neurocognitive test scores in the hippocampus and amygdala. This study reports the novel finding that R2t*, a measure that estimates tissue integrity, is more sensitive to tissue damage in limbic system structures than is atrophy. R2t* measurements can serve as a biomarker that is distinct from and complementary to volume measurements.

Abstract
Objective: To describe a holistic and comprehensive approach to the assessment of sufferer’s perceptio ns of health-related quality of life (HRQ oL) in a cohort of multiple sclerosis (MS) patients. Methods: The G EDMA (Grupo de Enfermedades Desmielinizantes de Madrid, in Spanish) study is an ongoing longitudinal survey using quantitative and qualitative methodologies. The baseline cohort consisted of a large sample of MS patients recruited from 13 hospitals in Madrid, Spain. Using a standardized protocol we collected data concerning the sociodemographic and health status characteristics of patients, as well as implementing a modified Spanish version of the Functio nal A ssessment of Multiple Sclerosis quality of life instrument. Primary caregivers were interviewed using a specific protocol combined with the Zarit Burden Interview. Results: The index cohort comprised 371 MS patients (68.7% female) of mean age 38.9 ± 0.9 years. A ge, sex and clinical form distribution were similar to other MS population-based surveys. There were 258 (69.5%) relapsing-remitting (RR) MS patients and 113 (30.5%) progressive MS patients. More than one-third of the married patients with progressive MS and almost a quarter of the RRMS patients separated or divorced following a diagnosis of MS; 71.3% of the progressive MS patients as well as 65.8% of the RRMS patients were unemployed as a consequence of the disease. Q ualitative analysis showed that friendship and family relationships and occupational status were the most significant dimensions influenced by MS. O n the other hand, the speech analysis of primary caregivers showed that emotional burden was related to patients’ physical disability. Furthermore, primary caregivers described the influence of MS on their own occupatio nal status, their nonacceptance of the disease, a perceptio n of a lack of support by other members of the family as well as a ‘selfish and intransigent’ attitude of the patients themselves. Conclusions: The analysis of the G EDMA cohort provides valuable information that helps clarify the impact of MS on patients’ HRQ oL.

Abstract
We studied the initial course of daily functioning in multiple sclerosis (MS). A cohort of 156 recently diagnosed patients was prospectively followed for three years (five measurements). Domains of interest were neurological deficits, physical functioning, mental health, social functioning and general health. An a priori distinction was made between a relapse onset group (n=128) and a non-relapse onset group (n=28). At baseline, neurological deficits are relatively minor for most patients, 26.3% have aberrant physical functioning scores, 38.5% have aberrant social functioning scores, 9% have aberrant mental health scores and 25% have aberrant general health scores. The neurological deficits and physical functioning deteriorated significantly over time. This deterioration was more pronounced and clinically relevant in the non-relapse onset group only. Mental health showed a significant, but not clinically relevant deterioration over time. Social functioning and general health showed non-significant effects for time. It is concluded that in the initial stage of MS, when neurological deficits are relatively minor and mental health is relatively unaffected, patients in both groups experience limitations in daily functioning. Patients in the non-relapse onset group have progressive neurological symptoms that are accompanied by progressive limitations in physical functioning, but not by progressive limitations in the other domains.

Abstract
Disease specific quality of life was measured in the Leeds Multiple Sclerosis (MS) Treatment Programme (n-/210) using the self-report Leeds MS Quality of Life (LMSQoL) scale. The results showed a significant and sustained increase in quality of life associated with ‘disease modifying’ treatment. This contrasts with the Expanded Disability Status Scores (EDSS), which showed no measurable improvement. An increase in the LMSQoL score did not correlate with baseline age, disease duration, disability or number of prior relapses. There was no significant difference in treatment effect between relapsing-remitting and secondary progressive MS patients, or between patients receiving different products. However, patients with a poor quality of life at baseline showed the most benefit from treatment. Those who had their treatment stopped due to progression, side-effects or lack of effect had significantly lower LMSQoL scores on treatment. In this study, the LMSQoL scale was responsive to change and was easy to administer in a clinical setting.

Abstract
The aim of this study was to examine, within the context of a treatment study, the relative contributions of depression and neuropsychological performance on patient ratings of cognitive functioning in a cohort of 58 moderately-depressed multiple sclerosis (MS) patients. All participants were randomized to one of three 16-week conventional treatments for depression. Assessments were conducted pre and post-treatment using: (1) Cognitive Function subscale of the Multiple Sclerosis Quality of Life-54 (MSQOL-54) to evaluate subjective cognitive impairment (SC), (2) Beck Depression Inventory (BDI), and (3) a neuropsychological index score (NP). Prior to treatment, 8% of the variance in SC was explained by NP, whereas 14% of the variance was explained by BDI, above and beyond NP. At post-treatment, patients were classified as ‘responders’ (BDI<11) and ‘nonresponders’ (BDI≥11). Among those participants classified as ‘responders’, NP accounted for 39% of the variance in SC, and BDI did not significantly predict SC. The results of this study suggest that depression may influence subjective reports of cognitive impairment, but these reports may not be reliably related to objective neuropsychological performance. Furthermore, patients may be more accurate reporters of their cognitive impairment after successful treatment for depression, suggesting that depression decreases the accuracy of patient reported cognitive impairment.

Abstract
This study intended to examine if the immune response to a cognitive task as a variant of psychological stress in MS patients is distinct from healthy controls. The experiment was part of a larger study on mechanisms and measurements of MS fatigue. Patients (n=23) and controls (n=25) participated in a cognitive task lasting 40 minutes, in which the heart rate was continuously monitored. Blood samples were taken at baseline and directly after the stress-inducing task. Whole blood stimulated cytokine production representative of the TH-1 (i.e. IFNγ, TNFα) and TH-2 paradigm (i.e. IL-10) was evaluated in relation to disability, fatigue, cognitive deficit, and anxiety. Patients scored high on a disease specific fatigue score compared to controls, whereas baseline cytokine patterns did not differ between the groups. MS patients displayed a blunted response of IFNg (P=0.03) whereas TNFα and IL-10 responses did not change. Additionally MS patients showed a significantly lower heart rate increase after the task (P<0.001). Cognitive impairment was associated with a decreased heart rate reactivity (P=0.02) while depressive symptoms correlated with stronger IL-10 responses (P=0.05). Overall, cognitive stress induces IFNγ production in healthy controls but not in MS patients with fatigue. Furthermore, a reduced cardiac response might indicate an autonomic dysfunction in this group of patients.

Abstract
When performing a novel task, people need to generate and apply a working strategy. The applicatio n of an appro priate working strategy enables patients with cognitive impairment (C I) to perform tasks efficiently, which in turn makes it easier to meet the challenges of daily life tasks. We investigated the strategy application abilities (SAA) of multiple sclerosis (MS) patients and compared these results with data based on healthy subjects’ performance. Seventy-six patients performed a Strategy A pplication Test (SAT) along with other cognitive tests, and completed depression, fatigue, and activity of daily living (A DL) questionnaires. O ur results indicated that 76% of the MS patients included had impaired SAA, and that this impairment was not correlated with their depression, fatigue, Expanded Disability Severity Scale (EDSS), or A DL. These findings may have important implications for the understanding of the capability of MS patients to cope with nonroutine tasks, as well as for the potential of future implementation of cognitive rehabilitation in improving the SAA of patients with MS or other cognitive disorders.

Abstract
Multiple Sclerosis (MS) is a chronic inflammatory/demyelinating and neurodegenerative disease of the central nervous system (CNS). Most patients experience a relapsing-remitting (RR) course, while about 15–20% of patients experience a primary progressive (PP) course. Cognitive impairment affects approximately 40–70% of all MS patients and differences in cognitive impairment between RR-MS and PP-MS have been found. We aimed to compare RR-MS and PP-MS patients in terms of cognitive performance, and to investigate the MRI correlates of cognitive impairment in the two groups using measures of brain volumes and cortical thickness. Fifty-seven patients (42 RR-MS, 15 PP-MS) and thirty-eight matched controls underwent neuropsychological (NP) testing and MRI. PP-MS patients scored lower than RR-MS patients on most of the NP tests in absence of any specific pattern. PP-MS patients showed significantly lower caudate volume. There was no significant difference in MRI correlates of cognitive impairment between the two groups except for a prevalent association with MRI measures of cortical GM injury in RR-MS patients and with MRI measures of subcortical GM injury in PP-MS patients. This suggests that although cognitive impairment results from several factors, cortical and subcortical GM injury may play a different role depending on the disease course.

Abstract
OBJECTIVES Although the transition to secondary progressive multiple sclerosis (SPMS) is known to be a period of uncertainty for clinicians, who may find progressive disease challenging to objectively identify, little research has explored the experiences of patients and carers specifically during this transition period. Our objective was to explore what patients and their carers understand about their disease stage and describe their experiences and perspectives on the transition to SPMS. DESIGN Semistructured qualitative interviews and subsequent validation focus groups were analysed using inductive thematic analysis. SETTING South East Wales, UK. PARTICIPANTS 20 patients with MS and 13 carers were interviewed. Eight patients and two carers participated in focus groups. RESULTS Four main themes around disease progression were identified. 'Realisation' describes how patients came to understand they had SPMS while 'reaction' describes their response to this realisation. The 'realities' of living with SPMS, including dealing with the healthcare system during this period, were described along with 'future challenges' envisaged by patients and carers. CONCLUSIONS Awareness that the transition to SPMS has occurred, and subsequent emotional reactions and coping strategies, varied widely between patients and their carers. The process of diagnosing the transition was often not transparent and some individuals wanted information to help them understand what the transition to SPMS meant for them.

Abstract
INTRODUCTION Cognitive impairment and the presence of depressive symptoms, which are commonly found in patients with multiple sclerosis, affect the patients' quality of life. AIM. To describe the quality of life, cognitive compromise and levels of depression, in relation to other clinical variables, in patients with multiple sclerosis in the province of Gipuzkoa. PATIENTS AND METHODS A total of 114 patients were submitted to neuropsychological evaluation. The MSQoL-54 and Beck's Depression Inventory were applied to evaluate the quality of life and levels of depression. Three main analyses were performed: a comparison of cognitive performance among subtypes, an analysis of the correlation among clinical, neuro-psychological and quality of life variables, and an analysis of the effects of gender on cognitive performance. RESULTS A neuropsychological pattern is found in multiple sclerosis that is characterised by a slowing of the processing of information and attentional difficulties. Quality of life is related with depressive syndromes and with overall cognitive performance but not with clinical factors such as the rate of attacks or the length of time the disease lasts. The data confirm the existence of poorer cognitive performance in males, above all in terms of verbal auditory memory. CONCLUSIONS Gender is presented as a factor that modulates the impact of the disease on cognitive performance, which reinforces the interest in conducting studies that clarify the origin of such differences. Furthermore, the quality of life displays a greater relationship with the degree of adaptation to the disease than with its symptoms.

Abstract
OBJECTIVE To investigate whether spatial working memory (WM) is impaired in multiple sclerosis (MS), and, if it is, to localize impairment to specific cognitive subprocess(es). METHOD In Experiment 1, MS and control participants performed computerized memory-span and visuomotor tasks. WM subprocesses were taxed by manipulating (1) the requirement to remember serial order, (2) delay duration, and (3) the presence of irrelevant stimuli during target presentation. In Experiment 2, recall and recognition tests varied the difficulty of WM retrieval. In Experiment 3, an attention-cueing task tested the ability to voluntarily and rapidly reorient attention. RESULTS Performance was worse for MS than for control participants in both spatial recall (Exp. 1 span: 95% CIMS = [5.11, 5.57], 95% CIControls = [5.58, 6.03], p = .003, 1-tailed; Exp. 2 span: 95% CIMS = [4.44, 5.54], 95% CIControls = [5.47, 6.57], p = .006, 1-tailed) and recognition (accuracy: 95% CIMS = [0.71, 0.81], 95% CIControls = [0.79, 0.88], p = .01, 1-tailed) tests. However, there was no evidence for deficits in spatiotemporal binding, maintenance, retrieval, distractor suppression, or visuomotor processing. In contrast, MS participants were abnormally slow to reorient attention (cueing effect (ms): 95% CIMS: [90, 169], 95% CIControls: [29, 107], p = .015, 1-tailed). CONCLUSIONS Results suggest that, whereas spatial WM is impaired in MS, once spatial information has been adequately encoded into WM, individuals with MS are, on average, able to maintain and retrieve this information. Impoverished encoding of spatial information, however, may be due to inefficient voluntary orienting of attention.

Abstract
To study mechanisms of development of cognitive dysfunctions in multiple sclerosis (MS), brain glucose metabolism has been investigated using PET method. We have studied 61 patients with different types of MS course. Correlations between cognitive dysfunctions and regional glucose metabolic rate were revealed. The authors suggest that metabolic dysfunctions of the grey matter play the important role in the pathogenesis of cognitive disturbances in MS.

Abstract
PURPOSE To illustrate how structural equation modeling (SEM) can be used for response shift detection with random measurement occasions and health state operationalized as fixed group membership (Study 1) or with fixed measurement occasions and health state operationalized as time-varying covariates (Study 2). METHODS In Study 1, we explored seven items of the Performance Scales measuring physical and mental aspects of perceived disability of 771 stable, 629 progressive, and 1,552 relapsing MS patients. Time lags between the three measurements varied and were accounted for by introducing time since diagnosis as an exogenous variable. In Study 2, we considered the SF-12 scales measuring physical and mental components of HRQoL of 1,767 patients. Health state was accounted for by exogenous variables relapse (yes/no) and symptoms (worse/same/better). RESULTS In Study 1, progressive and relapsing patients reported greater disability than stable patients but little longitudinal change. Some response shift was found with stable and relapsing patients. In Study 2, relapse and symptoms were associated with HRQoL, but no change and only little response shift was found. CONCLUSIONS While small response shifts were found, they had little impact on the evaluation of true change in performance and HRQoL.

Assessing the quality of sleep in Greek primary caregivers of patients with secondary progressive multiple sclerosis: a cross-sectional study. J Pain Symptom Manage 2011; 42:541-7. [PMID: 21444179 DOI: 10.1016/j.jpainsymman.2011.01.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2010] [Revised: 01/12/2011] [Accepted: 01/21/2011] [Indexed: 01/21/2023]
Abstract
CONTEXT Several studies have investigated the prevalence of sleep disorders in patients suffering from multiple sclerosis (MS) and have shown that up to 54% of patients may have significantly more sleep problems than the general population. To our knowledge, however, no data are available about the quality of sleep of the primary caregivers of patients with MS. OBJECTIVES The objectives of the current cross-sectional study were to assess the quality of sleep in Greek primary caregivers of patients with MS and to investigate its relationship with the degree of caregivers' emotional distress. METHODS Twenty-two male and 13 female primary caregivers (mean age 47.3±12.4 years) of an equal number of patients with MS, who consented to participate, completed the validated Greek version of the Pittsburgh Sleep Quality Index (PSQI) and the validated Greek version of the Hospital Anxiety and Depression Scale (HADS). Thirty-five age-, gender-, and education-matched healthy controls were used for comparisons. RESULTS Caregivers experienced a higher degree of anxiety than depression. The mean score in the seven-item HADS-A subscale was 9.5±4 (range 3-15) and the mean score in the seven-item HADS-D subscale was 7.1±3.1 (range 2-14). The mean scores of caregivers on both HADS-A and HADS-D were significantly higher than those of controls (P<0.001). The PSQI scoring demonstrated that 19 (54.3%) caregivers had poor sleep quality (cut-off value of >5). The mean values of caregivers for the PSQI were 6.0±2.8 (range 2-12) compared with controls, who scored at a significantly lower level (1.5±0.8; P<0.001). Poor quality of sleep was significantly correlated with increased levels of anxiety (r=0.392; P=0.02) and depression (r=0.424; P=0.01). Among the PSQI components, the sleep duration and sleep latency were mostly influenced by the degree of emotional distress. CONCLUSION A significant proportion of primary caregivers of MS patients experience poor sleep quality. The degree of their emotional distress appears to significantly influence their quality of sleep. Appropriate psychopharmacological interventions may be required for those individuals.

Abstract
A multicenter randomized post-registration control-comparative trial included 94 patients with relapsing-remitting and secondary-progressive multiple sclerosis (MS) in the acute phase. Patients were stratified into 2 groups: patients of group 1 (n=53) received cytoflavin and basic treatment (trental and group B vitamins) and patients of group 2 (n=41) received only basic treatment. Based on the results of the 5-day treatment, each of these groups was stratified into 2 subgroups: patients of subgroup 1A (n=22) who demonstrated a positive effect continued to receive cytoflavin and basic treatment; subgroup 1B (n=31) received corticosteroids (metipred) as an add-on in the pulse- treatment regime; group 2A (n=14) continued to receive basic treatment due to the positive effect; group 2B (n=27) received corticosteroids as an add-on in the pulse-treatment regime. The treatment including cytoflavin, trental, group B vitamins and corticosteroids, was well-tolerated. The positive effect was due to the decrease in the need for corticosteroids: 41.5% of patients treated with cytoflavin and only 34% of patients receiving basic treatment did not need corticosteroids. The significant reduction of neurologic symptoms assessed with the EDSS was seen in patients treated with cytoflavin compared to the group which did not receive this drug. The clinical effect was observed in all patients. There was a decrease in lipid peroxidation levels and in the content of antibodies to basic myelin protein and the improvement of cognitive function.

Abstract
INTRODUCTION Cognitive impairment is a symptom of multiple sclerosis (MS); however, in the primary progressive form of the disease (PPMS), data on the prevalence and type of cognitive impairment are controversial. AIM To evaluate the frequency of cognitive impairment, according to the diagnostic criteria defined by Thompson, in Brazilian patients with PPMS attending a referral center for the treatment of MS in Rio de Janeiro, Brazil. SUBJECTS AND METHODS A battery of neuropsychological tests was used to evaluate the following cognitive functions: screening for dementia, attention/concentration, speed of information processing, verbal fluency, memory and abstract/conceptual thought. The Beck scale was used to evaluate mood disorders. Twenty-six patients with PPMS and 26 controls paired for gender, age and education level were evaluated. Statistical analysis was based on the study performed by Rao. RESULTS The frequency of cognitive impairment in the PPMS patients in the present study was 50%. The cognitive functions most affected were: recent memory (60%), verbal fluency (40%) and speed of information processing (40%). Depression was more common in the PPMS patients compared to the control group; however, no association was found between cognitive impairment and depression. CONCLUSION These results confirm the presence of cognitive impairment in PPMS and emphasize the need for further studies with larger sample sizes.

Abstract
OBJECTIVE This longitudinal, observational study examined changes in physical activity and symptoms as correlates of changes in functional limitations and disability across a 6-month period among individuals with multiple sclerosis (MS). METHOD Individuals with MS wore an accelerometer for a 7-day period and completed a battery of measures including the Godin Leisure-Time Exercise Questionnaire (Godin & Shephard, 1985), Symptom Inventory (Schwartz, Vollmer, & Lee, 1999), MS-Related Symptom Checklist (Gulick, 1989), and abbreviated Late-Life Function and Disability Inventory (McAuley, Konopack, Motl, Rosengren, & Morris, 2005) at baseline (n = 292) and 6-month follow-up (n = 276). The data were analyzed using panel analysis with latent variables in AMOS 16.0. RESULTS The standardized coefficients indicated that (a) change in physical activity was associated with residual change in function (beta = .22), (b) change in symptoms was associated with residual changes in both function (beta = -.29) and disability (gamma = -.15), and (c) change in function was associated with residual change in disability (beta = .20). CONCLUSION Our findings indicate that change in physical activity is associated with change in disability through a pathway that is consistent with Nagi's (1976) Disablement Model and its extension in individuals with MS.

Abstract
BACKGROUND Multiple sclerosis is a disabling neurological disease with varied symptoms, including dysarthria and cognitive and linguistic impairments. Association between dysarthria and cognitive-linguistic deficit has not been explored in clinical multiple sclerosis studies. AIMS In patients with chronic progressive multiple sclerosis, the study aimed to investigate the presence and nature of cognitive-linguistic deficit, the association between levels of cognitive-linguistic ability and speech intelligibility, and of both of these with functional disability and time since onset of multiple sclerosis symptoms. METHODS & PROCEDURES The Arizona Battery for Communication Disorders of Dementia (ABCD) (Bayles and Tomoeda 1993 ), The Assessment of Intelligibility of Dysarthric Speech (AIDS) Sentence Intelligibility Task (Yorkston and Beukelman 1984 ), and the Modified Barthel Activities of Daily Living Index (MBADLI) (Shah 1998 ) were administered to 24 chronic progressive multiple sclerosis participants with dysarthria. A total of 24 non-neurologically impaired participants, matched for gender, age and education, formed a control group. OUTCOMES & RESULTS For multiple sclerosis participants, linear regression analysis showed a strong association between ABCD and AIDS (beta = 0.89, p = 0.005), no association between ABCD and either MBADLI or time since onset, a strong association between AIDS and MBADLI (beta = 0.60, p = 0.001), and a trend towards an association between AIDS and time since onset (beta = -0.29, p = 0.08). Correlations between the four included ABCD construct scores and between these and the total ABCD score were significant (r>0.60, p<0.01). For each of the 15 included ABCD measures and for the four construct scores and the overall ABCD score, multiple sclerosis and control group performances were significantly different (p<0.01) and effect sizes were large (d>0.80). CONCLUSIONS & IMPLICATIONS The results revealed a strong association between dysarthria, as measured by connected speech intelligibility testing, and cognitive-linguistic deficit, in people with chronic progressive-type multiple sclerosis. While some of the impairments that are associated with multiple sclerosis, including motor speech disorder, may influence performance on the ABCD, the data support the conclusion that marked cognitive-linguistic deficit is present in chronic progressive-type multiple sclerosis patients with dysarthria. Deterioration was global, rather than being indicative of a construct specific deficit, and encompassed language, both expression and comprehension. Episodic memory and linguistic expression were especially affected. Speech and language therapists who work with dysarthric patients with chronic progressive multiple sclerosis should monitor cognitive-linguistic impairment. An awareness of this might influence assessment, intervention and management, including the information and advice given to patients and their relatives.

Abstract
INTRODUCTION Patients with multiple sclerosis (MS) may have an impairment in their decision-making. Altered decision making is a known cause of functional impairment in daily living activities and in the patient's autonomy, negatively contributing to their quality of life. OBJECTIVE The current study assessed the decision-making capacity of patients with primary progressive multiple sclerosis (PPMS) and secondary progressive multiple sclerosis (SPMS) compared to healthy control subjects. PATIENTS AND METHODS Nineteen patients with multiple sclerosis (9 PPMS and 10 SPMS) and 18 healthy controls participated in the study. Decision-making was evaluated using a computerized version of the Iowa Gambling Task (IGT), a test created to simulate punishment-reward contingencies in a real-life manner. RESULTS Overall, the PPMS group performed more poorly than the control and SPMS groups on the IGT. The SPMS group was not significantly impaired compared to control group on the task, but showed abnormalities of IGT performance similar to the PPMS group. CONCLUSIONS The authors suggest that the existence of decision- making impairments in patients with multiple sclerosis can be explained by a difficulty in the acquisition of stimulus-reward contingencies.

Abstract
In this qualitative study, we explored the question of why some women with progressive forms of multiple sclerosis (MS) cope successfully in spite of disease progression. Ten women with progressive courses of MS, the more physically challenging forms of the disease, who self-reported as coping successfully with the disease, participated in the study. The study features an interview protocol using a psychotherapeutic model of change, precursors of change model, and incorporates a then-post design. The women's rich descriptions and explanations of precursors indicate the differences between the precursors used most frequently at time of diagnosis with MS and at the time of interview. The article provides a glimpse into the experiences these women have had with the continued change and unpredictability that the disease often engenders.

Abstract
Do people with multiple sclerosis who receive the majority of their care from neurologists perceive access to and quality of their care differently than people receiving their care from medical internists, family/general practitioners, and other types of physicians? The objective of this study is to identify any patient-identified differences in MS-related care by the practice specialty of the principal care physician, as well as differences by practice specialty in satisfaction with access to physician services and differences in patient perceptions of quality. Data were collected by surveying 1,518 people with MS throughout the United States and grouped by practice specialty of principal care physician (neurologist, internal medicine, family/general practice, and other physicians). Significant differences were observed by practice specialty of the principal care physician in physician understanding of various aspects of MS, satisfaction with access to MS-focused care, and quality of MS-focused care, with neurologists associated with better patient perceptions. Patients consider MS-related care superior when it is delivered by neurologists compared to MS patients receiving care from medical internists, family/general practitioners, and other physicians.

Abstract
Memory impairment is especially prominent within the spectrum of cognitive deficits in multiple sclerosis (MS), and a crucial role for hippocampal pathology may therefore be expected in this disease. This study is the first to systematically assess hippocampal demyelination in MS. Hippocampal tissue samples of 19 chronic MS cases and 7 controls with non-neurologic disease were stained immunohistochemically for myelin proteolipid protein. Subsequently, number, location, and size of demyelinated lesions were assessed. Furthermore, the specimens were stained for HLA-DR to investigate microglia/macrophage activity. An unexpectedly high number of lesions (n = 37) was found in 15 of the 19 MS cases. Mixed intrahippocampal-perihippocampal lesions, which were more often found in cases with cognitive decline, were large and did not respect anatomical borders. Moderate microglial activation was frequently observed at the edges of these mixed lesions. Isolated intrahippocampal lesions were also frequently found. These were smaller than the mixed lesions and had a specific anatomical predilection: the cornu ammonis 2 subregion and the hilus of the dentate gyrus were consistently spared. Microglial activation was rare in isolated intrahippocampal lesions. Our results indicate that hippocampal demyelination is frequent and extensive in MS and that anatomical localization, size, and inflammatory activity vary for different lesion types.

Abstract
The neurodegenerative aspects of chronic progressive multiple sclerosis (MS) have received increasing attention in recent years, since anti-inflammatory and immunosuppressive treatment strategies have largely failed. However, successful neuroprotection and/or neuroregeneration in MS have not been demonstrated yet. Encouraged by the multifaceted neuroprotective effects of recombinant human erythropoietin (rhEPO) in experimental models, we performed an investigator-driven, exploratory open label study (phase I/IIa) in patients with chronic progressive MS. Main study objectives were (i) evaluating safety of long-term high-dose intravenous rhEPO treatment in MS, and (ii) collecting first evidence of potential efficacy on clinical outcome parameters. Eight MS patients, five randomly assigned to high-dose (48,000 IU), three to low-dose (8000 IU) rhEPO treatment, and, as disease controls, two drug-naïve Parkinson patients (receiving 48,000 IU) were followed over up to 48 weeks: A 6-week lead-in phase, a 12-week treatment phase with weekly EPO, another 12-week treatment phase with bi-weekly EPO, and a 24-week post-treatment phase. Clinical and electrophysiological improvement of motor function, reflected by a reduction in expanded disability status scale (EDSS), and of cognitive performance was found upon high-dose EPO treatment in MS patients, persisting for three to six months after cessation of EPO application. In contrast, low-dose EPO MS patients and drug-naïve Parkinson patients did not improve in any of the parameters tested. There were no adverse events, no safety concerns and a surprisingly low need of blood-lettings. This first pilot study demonstrates the necessity and feasibility of controlled trials using high-dose rhEPO in chronic progressive MS.

Abstract
INTRODUCTION Memory symptom exaggeration or malingering in the forensic neuropsychological evaluation of well-documented brain pathology is seldom described. For some, documented neuropathology and malingering are considered to be mutually exclusive. CASE REPORT We report an original clinical observation of an amnesic factitious disorder in a patient with progressive multiple sclerosis. This patient, who was seen for a routine comprehensive neuropsychological evaluation, demonstrated a severe memory encoding deficit in a classical standard episodic memory test. This amnesic syndrome was not in agreement with the neurological condition where deficits in retrieval memory processes are essentially observed. Moreover, his performance at two symptom validity tests fell below the admitted cut-off scores. In fact, the patient obtained an accuracy score of 3 (cut-score<10) in the Rey's 15-Items Test, a well known malingered amnesia measure. His performance in the 21-Items Test French adaptation was well below the proposed cut-off score of 15/21 and inferior to the results obtained by an Alzheimer patients group (n=30). A clinical approach of memory symptom exaggeration is described. We discuss the diagnosis of this false disorder. CONCLUSION This case report demonstrates unequivocally that memory symptom exaggeration or malingering can and does occur in patients seen without litigious contexts and who have a well-documented neurological pathology. Failure to address malingering may compromise neuropsychological clinical findings. Nevertheless, there is a lack of up-to-date standard French-language documentation in this topic.

Abstract
The purpose of this study was to examine if there was a difference in the level of self-efficacy between men and women with relapsing-remitting multiple sclerosis (RRMS) and progressive forms of multiple sclerosis (MS). A quantitative, descriptive, comparative design was used. The convenience sample included 556 individuals with MS, of which 124 were men (73 RRMS and 51 progressive MS) and 432 women (348 RRMS and 84 progressive MS). Participants completed the Multiple Sclerosis Self-Efficacy Scale (MSSE). This study found gender differences in self-efficacy among those living with MS. The women had a significantly greater belief in their ability to function with MS. The women also had a greater belief in their ability to control their MS than the men, although the difference was not significant. This study also found significant differences in self-efficacy between those with RRMS and those with progressive forms of MS. When men were compared by type of MS, those with RRMS had significantly greater belief in their ability to control their disease and function with it than those with progressive forms of MS. For women, those with RRMS had significantly greater belief in their ability to control their MS and function with it than women with progressive forms of MS. Individuals with MS could benefit from strategies that enhance self-efficacy. Such strategies include providing skills for self-management of MS, providing education and support of the patient and family, introducing the patient to a role model with MS, encouraging physical reconditioning, and referring to a support group that will meet individualized needs.

Abstract
The ability of a newly developed measure of information processing to detect deficits in cognitive functioning associated with multiple sclerosis (MS) was investigated. The Computerized Tests of Information Processing (CTIP; Tombaugh, T., & Rees, L. (1999). Computerized Tests of Information Processing (CTIP). Unpublished test. Ottawa, Ontario, Canada: Carleton University) was administered to 60 clinically definite MS patients and 60 healthy controls. MS patients responded significantly slower than controls on the reaction time tests composing the CTIP. Moreover, as the CTIP tests became more difficult (i.e. as processing demands increased), the difference between the performances of the two groups progressively increased. These results suggest the CTIP is sensitive to the cognitive deficits observed in MS and that this measure has the potential to serve as a viable alternative to traditional measures of information processing speed currently in use with MS patients.

Abstract
We determined biopsychosocial correlates of general, physical, and mental fatigue in MS patients, by evaluating the additional contribution of potentially modifiable factors after accounting for non-modifiable disease-related factors. Fifty-three ambulatory MS patients, along with 28 normal controls were recruited for a cross-sectional study. Subjects completed the Multidimensional Fatigue Inventory (MFI) and Fatigue Severity Scale. Potential correlates evaluated were: disease-related factors (disease duration and type, immunomodulating treatment, muscle strength, pain, forced vital capacity (FVC), respiratory muscle strength, body mass index, disability, fibromyalgia), behavioural factors (physical activity, sleep quality) and psychosocial factors (depression, stress, self-efficacy). Multivariate models were calculated for MFI General, Physical, and Mental Fatigue. Age-adjusted multivariate models with non-modifiable factors included the following predictors (P < or = 0.10) of 1) MFI General and Mental Fatigue: none; and 2) MFI Physical Fatigue: FVC and disability. The following potentially modifiable predictors (P < or = 0.10) made an additional contribution to the models 1) MFI General Fatigue: sleep quality, self-efficacy, pain; 2) MFI Physical Fatigue: self-efficacy, physical activity; and 3) MFI Mental Fatigue: stress, self-efficacy. Fatigue in MS is multidimensional. Correlates of general and physical fatigue are disease-related, behavioural and psychosocial factors. Correlates of mental fatigue are psychosocial factors. Potentially modifiable factors account for a considerable portion of fatigue.

Abstract
Purpose Measures of quality of life (QoL) are increasingly used to monitor psychological and social well being of clients with chronic illnesses. They are particularly useful in cases where an illness results in multiple disabilities. Where clients have difficulty completing the measure, others who know them may act as proxies. It is important, therefore to assess the accuracy of proxy scores. This study compared the QoL scores given by people with multiple sclerosis (PWMS) with proxy scores given by close relatives. Method The Functional Assessment of Multiple Sclerosis (FAMS) quality of life instrument (Cella et al.) [1] was used. Forty PWMS completed the measure in face-to-face interviews with a speech and language therapist. Close relatives were asked to independently complete the measure on behalf of these clients. Results The overall correlation between client and proxy scores was 0.62, which Sneeuw et al. [2] suggest indicates good agreement. As in previous studies with other groups of clients, proxies underestimated the scores of PWMS. Despite these findings, the results showed substantial disagreements for individual clients and their proxies and a relationship was found which suggests that proxies underestimate the scores of clients with better QoL and overestimate those with poorer QoL scores. Conclusion The level of agreement found between client and proxy scores and the tendency for proxies to underestimate clients' scores are consistent with research with other client groups. The overestimation by proxies of clients who rate their QoL as poor needs further investigation. If confirmed it may complicate the estimation of client scores from those of proxies. We conclude that while proxy scores may be useful as a means of estimating the QoL of groups of clients in research studies they should be used cautiously in the prediction of the QoL of individual clients at the clinical level.

Abstract
OBJECTIVE To assess prevalence rates and clinical correlates of anxiety disorders in patients with multiple sclerosis (MS). METHODS Demographic and neurological data were collected on 140 consecutive clinic attendees, and their lifetime and point prevalences of anxiety disorders were determined with the Structured Clinical Interview for DSM-IV disorders (SCID-IV). All subjects completed the self-report Hospital Anxiety and Depression Scale (HADS). Suicidal intent was rated with the Beck Suicide Scale (BSS), psychosocial stressors and supports were quantified with Social Stress and Support Interview (SSSI), and cognition assessed with Neuropsychological Screening Battery for MS. RESULTS The lifetime prevalence of any anxiety disorder was 35.7%, with panic disorder (10%), obsessive compulsive disorder (8.6%), and generalized anxiety disorder (18.6%), the most common diagnoses obtained. Subjects with an anxiety disorder were more likely to be female, have a history of depression, drink to excess, report higher social stress and have contemplated suicide. The diagnosis of an anxiety disorder had been missed in the majority of subjects, therefore, they had not received treatment. A discriminant function analysis identified a series of variables that correctly classified 75% of patients with an anxiety disorder. CONCLUSION Anxiety disorders are common in patients with MS, but are frequently overlooked and under-treated. Risk factors include being female, a co-morbid diagnosis of depression, and limited social support. Clinicians should evaluate all MS subjects for anxiety disorders, as they represent a treatable cause of disability in MS.

Abstract
Physical therapy intervention for those with chronic disabling conditions typically follows an episode of care approach: therapists provide services when a decrement in functional performance occurs such that individuals require intervention to return to baseline performance. Attention to the psychosocial supports required for successful transition can be unintentionally minimized when the focus of an episode of care follows a change in physical function. The purpose of this case report is to present and discuss the challenges to successful community reintegration following physical therapy intervention with an emphasis on developing independent exercise habits in management of a person with multiple sclerosis. RW, presented in this case study, is a 52-year-old man diagnosed with progressive multiple sclerosis five years before self-referral to a pro bono physical therapy clinic.

The association of illness severity, self-reported cognitive impairment, and perceived illness management with depression and anxiety in a multiple sclerosis clinic population. J Behav Med 2007; 30:177-86.

Abstract
Within the multiple sclerosis (MS) population, high prevalence of psychiatric concerns, such as depression and anxiety, has been well documented. The purpose of this study was to examine factors contributing to higher depression and anxiety levels in a sample of 82 patients utilizing MS clinic services. Independent variables included MS physical severity, self-reported cognitive impairment, and perceived illness management, respectively. Results from hierarchical regression analyses indicated that depression was related to the physical severity, self-reported cognitive impairment, and perceived illness management variables. Anxiety was also related to the physical severity and self-reported cognitive impairment variables but not to the perceived illness management ones, suggesting that depression and anxiety symptoms may involve somewhat different processes within MS. The findings of this study support further clinical consideration and additional investigation of these variables in the treatment of anxiety and depression in an MS clinic population.

Abstract
The aim of this study was to use neuropsychological data to characterize two subtypes of multiple sclerosis (MS) patients in a large patient sample. We studied patients with primary-progressive MS (PPMS) and secondary-progressive MS (SPMS). A group of 121 MS patients (36 PPS, 85 SPMS) and 40 healthy controls were administered a brief battery of cognitive tests. Executive functioning, memory and attention were studied. Results demonstrate that PPMS patients exhibited slightly more impairment than patients with SPMS, although this difference is not significant (50% vs 37%). However, PPMS patients revealed a significantly poorer performance in verbal learning (p < 0.05) and in verbal fluency (p < 0.05). Whereas PPMS patients had significantly shorter disease durations (p < 0.05), there was no statistical difference in disability between both groups. We conclude from our study that cognitive deficits in progressive MS are frequent. Patients with PPMS tend to be more frequently and severely affected than SPMS patients. Our findings of high prevalence of cognitive involvement in PPMS have not been reported previously

Abstract
BACKGROUND No previous research exists specifically exploring the needs of those people severely affected by multiple sclerosis (MS). METHODS Semi-structured interviews were conducted with people identified by the referring health or social care professional as being severely affected by their MS and informal carers, in order to explore their perceptions of their illness and care. The data were analysed for themes using the constant comparative approach. RESULTS The data relate to 32 people severely affected by MS, who identified several broad themes, relating to loss and change, and provision of services and care. In relation to service provision, people with MS (PwMS) and their carers identified two, interlinked themes--a lack of continuity and co-ordination of care, and a lack of information about services, aids and adaptations, welfare benefits and end-of-life issues. A further theme was identified, which underpinned and linked the two other themes, that of ;fighting for everything'--a sense that people had to struggle for their needs to be met. CONCLUSION There is a need to develop models of care in order to better meet patients and carers needs for information, co-ordination, and to reduce the feeling of struggling to receive services.

Abstract
Multiple sclerosis (MS) is an inflammatory and degenerative disease of the central nervous system (CNS) that causes white matter and cortical lesions over many years. The CNS is selectively affected by the disease with a great variety of symptoms between patients. In this study, we describe the impact on various aspects of cognition over an 8-year follow-up period in 31 consecutive MS patients subgrouped as relapsing remitting (RR) MS, secondary progressive (SP) MS, and primary progressive (PP) MS. Results showed a differential pattern of cognitive decline already at baseline in speed of information processing. During the follow-up, a pronounced decline occurred in speed of information processing, finger-motor speed, copying geometrical designs, episodic memory, and visuospatial short-term memory. A striking difference was observed between a marked decline in visual reaction time, whereas no significant change was seen in auditory reaction time. In contrast, there was no time-related decline in verbal abilities. However, an initial marked cognitive impairment predicted further cognitive decline over the 8-year follow-up. Information-processing tests were found to be an especially strong predictor of long-term cognitive decline. In addition, high EDSS score at follow-up was associated with decline in information processes. Results also showed that SP-MS patients deteriorated significantly more than the other two groups, particularly in visual compared to auditory information processing. To conclude, cognitive decline appeared particularly in SP-MS patients and in visual information processing.

Abstract
Multiple sclerosis (MS) is a disease of the central nervous system that causes cognitive impairment with a frequency of roughly 50%. While processing speed and memory defects are most commonly observed, a substantial number of patients also have deficiency in higher executive ability. Two tests, the Wisconsin Card Sorting Test (WCST) and the Sorting Test from the Delis-Kaplan Executive Function System (DKEFS), have been recommended for evaluation of neuropsychological impairment in MS. We investigated the validity of these tests in 111 MS patients and 46 age- and education-matched controls. MS patients performed more poorly on both measures, but only the DKEFS discriminated the groups after controlling for depression. Both tests were modestly or strongly correlated with MRI indices of brain atrophy or lesion burden and discriminated between employed and disabled patients. While both tests appear to have good validity in the MS population, the availability of alternative forms makes the DKEFS an attractive alternative to the WCST, as was suggested by a consensus panel.

Abstract
Common disability scales in multiple sclerosis (MS) are often weighted towards physical disability. Non-motor symptoms such as depression, fatigue and pain substantially influence wellbeing in MS. Health-related quality of life (HRQoL) measures the broader impact of MS and might indicate less obvious disease burdens. We analysed HRQoL, using the Nottingham Health Profile Part I (NHP-I), among 345 secondary progressive MS (SPMS) patients participating in a randomized trial of interferon-β1a (IFN-β1a), 22 μg subcutaneously weekly, or matching placebo. The results did not reveal any beneficial effect of IFN-β1a in any outcome measure. NHP-I sub- and sum scores were compared for 217 population controls and correlated with demographic and clinical disease variables. SPMS patients had lower NHP-I sum and all subscores than the controls. Patients experiencing disease progression reported worse NHP-I sum scores. Increased fatigue, Expanded Disability Status Scale (EDSS) and Arm Index scores were independently associated with reduction in several NHP-I subscores. SPMS patients had significantly lower HRQoL than controls and physical disability (EDSS and Arm Index), disease progression and fatigue strongly influenced this. MS

Abstract
INTRODUCTION and objective The aim of this study was to compare coping strategies and quality of life (QoL) in multiple sclerosis (MS), as they relate to the course of the disease (relapsing-remitting (RR), secondary progressive (SP), primary progressive (PP)), while taking depression and anxiety into account. METHODS A total of 135 MS subjects were seen for a semi-structured interview in order to collect socio-demographic and clinical information, after which there was an assessment of their mental and cognitive states (Mini International Neuropsychiatric Interview (MINI), Montgomery and Asberg Depression Rating Scale (MADRS), Depressive Mood Scale (EHD), Hamilton Anxiety (HAMA), Frontal Assessment Battery (FAB)). All subjects then completed three self-report questionnaires; two about coping strategies (Ways of Coping Checklist (WCC), Coping with Health, Injuries and Problems Scale (CHIP)) and one about QoL (SEP59). RESULTS The mental health (depression and anxiety) and the psychological and social dimensions of QoL were relatively unaffected. However, after controlling for age and disability, the disease course had a strong effect on both mental health and QoL, with the poorest condition for SPMS and the best condition for PPMS. The SPMS patients tend to use emotional coping strategies extensively, while the PPMS patients use more instrumental strategies. DISCUSSION Our study clearly demonstrated that psychological and social well-being were substantially affected by the disease course. These results encourage us to develop interventions focused on coping strategies and which are better adapted to individual patients.

Abstract
BACKGROUND Memory dysfunction is common in multiple sclerosis (MS). A retrieval failure has been reported as the primary cause for the memory deficits, although some studies also described a faulty acquisition. AIMS The aim of the study was to examine memory function in relapsing remitting (RR) and secondary progressive (SP) MS patients, analyze the patterns of performance and to investigate whether disease course influences this performance. DESIGN AND SETTINGS Case-control prospective study conducted in a clinical setting. MATERIALS AND METHODS Fifty-five RR, 23 SP MS patients and 80 normal subjects were evaluated with a comprehensive neuropsychological battery. Memory was assessed with tasks from the Signoret memory battery. Attention and executive function were also assessed. STATISTICAL ANALYSIS Univariate analysis of variance, Mann-Whitney U-test, multivariate logistic regression and Chi-square test were used as appropriate. RESULTS MS patients performed significantly worse than controls on almost all measures of memory (P < 0,001). MS subgroups differed in tasks of delayed recall (logical memory- P =0,019; wordlist delayed recall, P < 0,001), semantic cued recall (P < 0,001), recognition trials (P =0,006) rate of forgetting (P < 0,001) and confabulation and intrusion errors (P =0,004). CONCLUSIONS Memory is consistently impaired in MS patients and disease course differentially affects the pattern of performance. SP patients show greater difficulties and a more pervasive pattern of dysfunction than RR patients. Delayed recall was the most affected memory measure and performance on this task discriminates between RR and SP MS patients. Relapsing remitting patients performed within the mildly impaired range while SP patients showed a moderate to severe impairment.

Abstract
The Functional Assessment of Multiple Sclerosis (FAMS) quality of life (QoL) instrument is a disease-specific, self-report questionnaire that was developed originally for US English-speaking patients. Here, the psychometric properties of the FAMS QoL questionnaire for Italian-speaking patients with multiple sclerosis (MS) are evaluated and compared with the results from the original FAMS validation survey (n=377). Eighteen Italian centers and 344 patients with MS participated in the study. The overall reliability (as expressed by Cronbach's alpha value) of the FAMS score, and its subscale scores, was always over the threshold of 0.8. Patients with benign MS showed a better overall QoL compared with patients with relapsing-remitting MS (RRMS; p=0.017), whereas patients with RRMS had a better QoL than patients with primary progressive MS (PPMS). No difference in QoL was found between patients with PPMS and those with secondary progressive MS. The Italian FAMS questionnaire is a valid measure to assess the QoL concerns of patients with MS. FAMS is also easy to administer and is well accepted by patients.

Abstract
INTRODUCTION Cognitive deficit in multiple sclerosis (MS) is a frequent early feature in the disease course, which conditions patients' overall disability. The goals of this study were to validate a reproducible brief screening battery written in French and to examine cognitive risk profiles in patients with a mild physical disability. METHODS Cognitive performances of 40 patients with EDSS <4.5 were compared with those of a control group. The study was completed with an analysis of socio-demographic, clinical and psychological variables (questionnaires). RESULTS Three tests were discriminative with satisfactory predictive values (positive: 88 percent; negative: 96 percent) and a time duration <30 minutes: PASAT (hard condition), backward digit span, learning stage of California Verbal Learning Test. Four variables were associated with cognitive deficit: educational level <11 years, age >40 years, pathological laughing-crying, unemployment. CONCLUSIONS Our brief battery is an easy and reproducible tool. Completed with warning signs indicating the need for neuropsychological screening, this tool provides the practitioner with a global means of assessing disease activity and potentially therapeutic efficacy.

Abstract
Multiple sclerosis (MS) is rare in children and the efficacy and safety of interferon beta 1b (IFN-beta 1b) treatment in childhood MS has not yet been established. We started to treat a boy who suffered from relapsing remitting MS with IFN-beta 1b at 8.5 years of age, because he had severe neurological disability in consequence of frequent relapses and incomplete remission. After initiating IFN-beta 1b treatment, his clinical course moved to secondary progressive (SP) MS, and he demonstrated poor improvement in degenerative progression and his disability continued to worsen. We could speculate that IFN-beta 1b was not effective regarding the degenerative component of childhood MS as in that of adult MS. SPMS is extremely rare in children, and this case would provide a very important implication to predict the tolerability of IFN-beta 1b treatment depending on the type of clinical course in childhood MS.

Abstract
BACKGROUND Despite the high lifetime prevalence of depression in multiple sclerosis (MS), its longitudinal course is poorly understood. OBJECTIVE To examine the longitudinal course of and reliable change in different depression symptom clusters in MS, and the longitudinal association of interferon beta treatment and coping with depression symptoms. METHODS 53 MS patients were examined at two time points three years apart on the Beck Depression Inventory (BDI) and the Chicago Multiscale Depression Inventory (CMDI). RESULTS Correlations from time 1 to time 2 for BDI, CMDI-total, CMDI-evaluative scale, and CMDI-vegetative scale were all highly significant, and reliable change indices reflected little change over time. In contrast, the correlation over time for the CMDI-mood scale was significantly lower (p<0.05) than the CMDI-evaluative and CMDI-vegetative scale correlations, and over 40% of patients showed reliable change. Patients who improved in their mood showed increased use of active coping, while patients who worsened showed decreased active coping strategies; the latter were also significantly more likely to have been taking interferon beta drugs at both time points than patients who did not change in their mood functioning. CONCLUSIONS Mood symptoms of depression are significantly more variable over time than neurovegetative or negative evaluative symptoms in MS patients. Decreased use of active coping strategies may put patients at risk of increased depressed mood, whereas increased use of active coping may result in decreased depressed mood longitudinally. Interferon beta use may put patients at risk of increases in depressed mood.
