Emotional stress and coping in multiple sclerosis (MS) exacerbations

The association between multiple sclerosis and early psychiatric background

BACKGROUND

The exact cause of Multiple Sclerosis (MS) is unclear. Since its definition in the late 19th century, researchers have repeatedly suggested a connection between the disease and mental state. Studies have shown that mental symptoms tend to precede the initiation of the disease by up to ten years. However, the hypothesis that psychiatric issues might precede MS onset by longer periods has not been empirically established. This study seeks to fill this research gap. The current matched cohort study investigated the possibility that psychiatric conditions may precede the initiation of multiple sclerosis by 15 years or more METHODS: A retrospective analysis utilizing the electronic database of Clalit Health Services (CHS), Israel's largest HMO, compared a group of 9,533 MS-diagnosed female and male individuals with 28,599 non-MS matched controls RESULTS: Logistic regression analysis revealed a significant association (p < 0.001) between MS diagnosis and prior psychiatric conditions, indicating a 93% increased likelihood of psychiatric history among those later diagnosed with MS compared with those who were not CONCLUSIONS: The heightened probability of mental health issues preceding the onset of MS by extended durations suggests a potential etiological role in the development of MS, rather than solely representing a component of the prodromal stage of the disease. Limitations include the retrospective design and the need for prospective studies to validate these associations.

Investigation of the Relationship Between Coping With the Disease and Affecting Cognitive, Physical, and Psychosocial Factors in People with Multiple Sclerosis

OBJECTIVE

To investigate the relationship between coping mechanisms in people with multiple sclerosis (MS, pwMS) and cognitive, physical, and psychosocial factors such as socio-demographic characteristics, disability, personality, stigma, quality of life, depression, and anxiety.

METHOD

One hundred and two pwMS were enrolled in this cross-sectional study. Demographics and clinical characteristics were recorded. Coping with the MS Scale (CMSS), including seven subscales, which are problem-solving, physical assistance, acceptance, avoidance, personal health control, energy conservation, and emotional release, was used to measure coping. Anxiety and depression levels, stigma, neuropsychological symptoms, and personality were measured by the Hospital Anxiety and Depression Scale (HAD), EuroQol-5D Quality of Life Scale (EQ-5D), Quality of Life in Neurological Diseases (NeuroQoL) -Stigma Scale, Multiple Sclerosis Neuropsychological Questionnaire (MSNQ), and Revised Eysenck Personality Questionnaire-Abbreviated Form (EKA-GGK), respectively.

RESULTS

There was a weak statistically significant positive correlation between the physical support subscale and age and the disease duration and a strong positive correlation with EDSS (r = .214, p = .035; r = .213, p = .036; r = .582, p ≤ .0001, respectively). There was a moderate negative relationship between the physical support subscale and the EQ-5D mobility, self-care, pain, and health subscales (r = -.434, p = .000; r = -.482, p = .000; r = -.526, p ≤ .001, respectively), a weak negative correlation with anxiety, and a strong negative relationship with usual activities (r = -.379, p ≤ .001; r = -.243, p = .017; r = -.384, p ≤ .001, respectively).

CONCLUSION

It has been shown that coping with MS can be affected by cognitive, physical, and psychosocial factors.

Coping Style Moderates the Effect of Pain on Depression Symptoms in Multiple Sclerosis

OBJECTIVE

The present study examined coping style as a possible moderator in the relationship between pain and depression in persons with multiple sclerosis (PwMS).

METHODS

Fifty-four PwMS completed a comprehensive neuropsychological test battery and psychosocial questionnaires that assessed physical, cognitive, and emotional functioning. Using four pain indices (i.e., average pain, current pain, pain intensity, and pain interference) from the Brief Pain Inventory (BPI), an overall pain index was created to capture a more comprehensive index of individuals' overall pain intensity and interference. The COPE questionnaire was used to derive three coping indices: active coping, avoidant coping, and a composite cope index that accounts for the relative contributions of both active and avoidant coping. The Beck Depression Inventory-Fast Screen (BDI-FS) was used to measure depressive symptomatology. A series of hierarchical linear regressions were conducted with depressive symptoms as the outcome variable.

RESULTS

Regression analyses revealed that the interactions between overall pain and each conceptualization of coping were significant (p = .001-.003). Simple effects tests revealed that overall pain only predicted depressive symptoms in PwMS with low active coping (p < .001), high avoidant coping (p < .001), and less adaptive coping via the composite coping index (p < .001).

CONCLUSION

We found that pain predicted depressive symptoms in PwMS who utilized more avoidant and less active coping strategies. Interventions aimed to improve coping style may be effective in enhancing the ability to manage pain and, subsequently, improve depression outcomes in MS.

A patient-centred evaluation of phantom skin wetness as a sensory symptom in people with multiple sclerosis

BACKGROUND

A noticeable but unknown proportion of people with multiple sclerosis (pwMS) report the sudden experience of wetness on a dry skin site, i.e., phantom wetness. Yet, we lack patient-centred investigations on the prevalence and subjective experience of this uncomfortable symptom.

OBJECTIVES

To assess the prevalence of phantom wetness in pwMS, its association with individual factors, and subjective experience.

METHODS

757 pwMS completed an online survey assessing the frequency and subjective experience of phantom wetness. We calculated descriptive statistics and odd ratios and performed a thematic analysis to extract a patient-centred description of phantom wetness.

RESULTS

220 participants reported experiencing phantom wetness (29%). Females and those affected by Relapsing Remitting (RR) MS were 2.17 [1.39, 3.34] (p<0.001) and 1.73 [1.23, 2.40] (p = 0.001) times as likely to experience phantom wetness as males and those not affected by RR MS, respectively. The thematic analysis indicated phantom wetness is more often experienced as water trickling on the skin of the lower limb.

CONCLUSION

Phantom wetness is a paraesthesia occurring in almost a third of the sample surveyed. Clinicians are encouraged to discuss with pwMS to validate their experience as a genuine symptom. Using the patient-generated language we report may help facilitate such conversations.

Coping strategies in relapsing-remitting multiple sclerosis non-depressed patients and their associations with disease activity

Few studies evaluated coping strategies in people with multiple sclerosis (pwMS) in relation to annualized relapse rate (ARR) and lesion load (LL). Overall, results might have been influenced by the inclusion of depressed patients. To investigate the coping strategies and their association to disease activity, we studied relapsing-remitting pwMS accurately selected to avoid the confounding effect of depression. Sixty-seven relapsing-remitting pwMS and 67 healthy subjects (HS) underwent to Coping Orientation to Problems Experienced (I-COPE) and Coping Inventory for Stressful Situation (CISS) and Beck Depression Inventory-II. Cognitive performances, ARR, physical disability and magnetic resonance imaging T2-LL were assessed for correlation with coping and depression scores. pwMS showed lower scores than HSs on social support and turning to religion subscales of I-COPE and on emotion dimension of CISS. In pwMS, higher ARR was related to higher positive attitude and lower score on the turning to religion subscale of I-COPE. The present study revealed a less employment of emotion-based coping strategies in pwMS. A scarce use of faith for support and a frequent adoption of a positive attitude were associated with an increase of MS activity in terms of ARR.

The use of generic avoidant coping scales for psychosocial adaptation to chronic illness and disability: A systematic review

This systematic review examined the validity of generic coping-with-stress measures in the relationships between avoidance-type coping and psychosocial adaptation to chronic illness and disability. Major data bases were searched for studies on the association between avoidance-type coping and psychosocial adaptation to chronic illness and disability. Findings indicated that reliance upon avoidance-type coping is linked to reports of poorer psychosocial adaptation. The veracity of these findings must be treated cautiously owing to conceptual, structural, psychometric, and other issues. Users of generic coping measures should consider these concerns prior to empirically investigating the link between generic avoidance-type coping measures and psychosocial adaptation among people with chronic illness and disability.

The Physical Burden of Immunoperception

The previous chapter introduced the ImmunoEmotional Regulatory System (IMMERS). Also, there was a brief discussion about psychological states/psychiatric disorders that so far have been linked to the IMMERS. The present chapter considers another aspect of the IMMERS in which physiological states/physical diseases can be fit to the IMMERS.

The role of stress in the mosaic of autoimmunity: An overlooked association

Stress is defined as the pscyophysiological reaction in which the steady state is disturbed or threatened. Stress is not always perceived as a negative response. Stress results when environmental demands exceed an individuals' adaptive capacities. Autoimmune diseases are heterogeneous group of chronic diseases which occur secondary to loss of self antigen tolerance. The etiopathogenesis of autoimmune disease is uncertain. Genetic factors as well as environmental factors appear to interplay, leading to a cascade of events resulting in disease onset. Stress has been postulated to play a role in disease onset in the genetically susceptible patients. During the stress response, catecholamines and glucocorticoids are released from locus coeruleus and adrenal gland. These biomolecules exert control over various immune cells in the innate and adaptive arms of the immune system, thereby altering the cytokine profile released. The increase of IL-4 promotes T-helper 2 (T_h2) cell differentiation, while the decrease in IL-12 and the increased IL-10 production reduce the number of T-helper 1 (T_h1) cells. The relationship between stress and autoimmune diseases is intricate. Stress has been shown to be associated with disease onset, and disease exacerbations in rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease, multiple sclerosis, Graves' disease as well as other autoimmune conditions. In certain conditions such as psoriasis, stress has been implicated in delaying lesion clearance upon the application of standard treatment regimes. Finally, psychological therapy and cognitive behavioral therapy aimed to reduce stress levels was shown to be effective in influencing better outcomes in many autoimmune diseases. The purpose of this paper is to closer inspect the clinical evidence regarding the role of stress on influencing the various aspects of disease entities.

Combined evaluation of personality, risk and coping in MS patients: A step towards individualized treatment choice - The PeRiCoMS-Study I

BACKGROUND

Multiple sclerosis (MS) is a chronic inflammatory neurological disease requiring disease-modifying treatment (DMT). To provide patients with the optimal individual therapeutic option, treatment recommendations should be based not only on individual disease course and DMT specific benefit-risk estimates, but also on patient's individual characteristics such as personality, risk attitude and coping strategies. However, these characteristics are difficult to objectify in clinical routine practice without the support of appropriate evaluation instruments.

OBJECTIVE

To identify and to assemble an objective test battery measuring personality, risk attitude and coping strategies in MS patients.

METHODS

A comprehensive literature search was performed to obtain all questionnaires assessing personality, risk attitude and coping strategies. Availability in German language, validation in a published normative collective and a reliability of >0.70 were required for our purposes. Based on these criteria, we chose the Big-Five-Personality Test, UPPS Impulsive Behaviour Scale, Domain-Specific Risk-Taking scale (DOSPERT), Brief-COPE and Stress & Coping Inventory (SCI). Results were compared to published normative controls of the respective questionnaires.

RESULTS

Out of 22 MS patients (7 males, 15 females) participating in this study, 19 (86.4%) completed all questionnaires. The median completion time was 45min (min-max range: 25-60min). The median scores of the MS group were within the average range of published control samples in all questionnaires.

CONCLUSIONS

We report that traits of personality, risk attitude and coping strategies can be effectively and feasibly tested in MS patients by the instruments used in our exploratory study. There were no differences between MS patients and healthy controls, thus enabling assessment without being influenced by the diagnosis of MS. After validation in a larger cohort the "PeRiCoMS"-battery will be useful as another step towards a more individualized shared-decision-making in every day routine practice.

A review of stress-relapse interactions in multiple sclerosis: important features and stress-mediating and -moderating variables

Studies do not provide a consensus opinion of the relationship between stress and relapse in relapsing=remitting multiple sclerosis (RRMS). Few studies have defined the critical features of these stressful situations, or examined the role of stress-mediating and -moderating variables. Available evidence indicates that the relationship between life stress and relapse is complex, and is likely to depend on factors such as stressor chronicity, frequency, severity and type, and individual patient characteristics such as depression, health locus of control and coping strategy use. Little is known about how these factors, individually or in combination, are related to MS disease activity. Viral infections are also likely to precipitate relapse in MS, and significant life-stress may further enhance this relationship. The nature and strength of these interrelationships have strong clinical implications. MS patients are particularly vulnerable to a deteriorating cycle of stressful life events, illness episodes and disability. Timely multidisciplinary care interventions aimed at both minimizing psychological distress and physical symptoms may halt this downward reciprocal cycle. Little is known of the pathogenesis of these putative stress-induced changes in disease activity, and almost all stressor studies suffer from some biases or limitations.

Relationship between stress and relapse in multiple sclerosis: part I. Important features

Objective The aim of this two-year prospective study was to examine the relationship between multiple aspects of life-event stress and relapse in multiple sclerosis (MS) patients.

Background Few studies have defined the critical features of this life-event stress; for example, stressor duration, frequency, severity, disease-dependency, valency, or stressor constructs, such as the propensity to cause emotional distress/threat or the frustration of life goals.

Methods 101 consecutive participants with MS were recruited from two MS clinics in Sydney, Australia. Stressful life events were assessed at study-entry and at three-monthly intervals for two years. Patient-reported relapses were recorded and corroborated by neurologists or evaluated against accepted relapse criteria.

Results Acute events, but not chronic difficulties (CDs), predicted relapse occurrence: acute stressor frequency counts predicted greater relapse risk, along with low disability score (EDSS) and being male. We also confirmed the bi-directional stress-illness hypothesis: stressors predicted relapse, and relapse separately predicted stressors.

Conclusions Life-event stress impacts to a small degree on MS relapse. The number and not the severity of acute stressors are most important; chronic stressors do not predict later relapse. Males and those with early stage disease are also at greater risk of relapse. MS patients should be encouraged to reduce acute stressors during times of high stress, and feel reassured that disease-related chronic stressors do not increase their relapse risk.

The Effects of Economic Disadvantage on Psychological Well-being and Quality of Life among People with Multiple Sclerosis

This study investigated the impact of economic disadvantage among people with multiple sclerosis (MS) on their psychological well-being and quality of life. Participants were 113 people with MS (31 males, 82 females). Information was obtained on income, lost income, costs of MS, economic pressure, coping, psychological well-being and quality of life. Economic pressure, and not actual MS-related costs predicted psychological well-being. Costs, economic pressure and coping predicted quality of life. These results demonstrate that pressure due to changed economic circumstances, as well as coping with these pressures is important in the quality of life of people with MS.

Stress and multiple sclerosis: A systematic review considering potential moderating and mediating factors and methods of assessing stress

Research about the effects of stress on multiple sclerosis has yielded contradictory results. This study aims to systematically review the evidence focusing on two possible causes: the role of stress assessment and potential moderating and mediating factors. The Web of Knowledge (MEDLINE and Web of Science), Scopus, and PsycINFO databases were searched for relevant articles published from 1900 through December 2014 using the terms "stress*" AND "multiple sclerosis." Twenty-three articles were included. Studies focused on the effect of stress on multiple sclerosis onset (n = 9) were mostly retrospective, and semi-structured interviews and scales yielded the most consistent associations. Studies focused on multiple sclerosis progression (n = 14) were mostly prospective, and self-reported diaries yielded the most consistent results. The most important modifying factors were stressor duration, severity, and frequency; cardiovascular reactivity and heart rate; and social support and escitalopram intake. Future studies should consider the use of prospective design with self-reported evaluations and the study of moderators and mediators related to amount of stress and autonomic nervous system reactivity to determine the effects of stress on multiple sclerosis.

A study of psychological well-being in people with multiple sclerosis and their primary caregivers

Background:

Multiple sclerosis (MS) is the most common disabling disease of the central nervous system. In these patients, fatigue is the most common symptom that causes disorder in the work, social activities and daily functions of the patients. Given the assumption that MS reduces the patients’ psychological well-being, this study aimed at assessing the psychological well-being of both the patients and their primary caregivers.

Materials and Methods:

Current research as a descriptive study was conducted on 200 MS patients and 200 primary caregivers. For data collection, the Reef questionnaire was used to determine psychological well-being of these individuals. Data were analyzed using SPSS software.

Results:

According to the obtained results, the mean duration of MS was estimated 6.37 years. The psychological well-being score of the people with MS and their primary caregivers was slightly higher than average. The total score of psychological well-being in primary caregivers was higher than the patients.

Conclusion:

The mean score of psychological well-being subscales was significantly different in patients and their caregivers. Regarding the autonomy subscale, there was a significant different in patients with MS, that is, it was lower than average. In terms of two subscales of “positive relationship with others” and “personal growth,” there was no difference between people with MS and the primary caregivers, and for other subscales, the mean score of caregivers was higher than the patients.

Prospective examination of anxiety and depression before and during confirmed and pseudoexacerbations in patients with multiple sclerosis

OBJECTIVE

This study was designed to determine whether pseudoexacerbations and confirmed MS exacerbations are preceded by or concurrent with increased anxiety or depressive symptoms.

METHODS

This was a secondary analysis of 121 patients with MS who were observed for 48 weeks during a randomized controlled trial. Participants completed monthly self-reports on depressive and anxiety symptoms. Patient-reported exacerbations were assessed through a telephone-administered symptom checklist and neurologic examination.

RESULTS

Both pseudoexacerbations and confirmed exacerbations were associated with concurrent somatic depressive (β = .16 and β = .33, respectively; p values < .05), affective depressive (β = .17 [p = .02] and β = .12 [p = .06]), and anxiety symptoms (β = .24 and β = .20, p values < .01), controlling for baseline symptoms. Preexisting somatic and affective depressive symptoms predicted amplified relationships between concurrent confirmed exacerbations and these symptoms (β = .19 and β = .20, respectively; p values < .01). A standard deviation increase in anxiety symptoms relative to baseline predicted subsequent onset of pseudoexacerbations (odds ratio = 1.54, p = .02), whereas increased somatic depressive symptoms predicted confirmed exacerbations (odds ratio = 1.59, p = .01).

CONCLUSIONS

Patients with MS experiencing pseudoexacerbations or confirmed exacerbations should be assessed and monitored for depressive and anxiety symptoms, and confirmed exacerbations are particularly concerning in patients with a history of depression. The psychological or psychiatric antecedents of MS exacerbations generate new hypotheses on etiologies of confirmed exacerbations and pseudoexacerbations.

Coping strategies, cognitive impairment, psychological variables and their relationship with quality of life in multiple sclerosis

Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system typically affecting young adults. Psychological coping has proved to be crucially important for adjusting to the adaptive demands of chronic diseases, and in the last few years it has received growing interest in MS. A common finding in the literature is that MS patients tend to adopt dysfunctional avoiding strategies and to rely less on task-oriented and positive attitude strategies, which represent a better adjustment to disease-related challenges. Moreover, the studies show higher psychoticism in MS subjects compared with the general population, and higher levels of depression and anxiety that can contribute to lower QoL perception. In our study including 63 MS patients cognitive functioning did not seem to influence the type of coping. However, subjects with impairment on tasks that assess sustained attention and some aspects of executive function were less prone to adopt positive coping strategies. Cognitive and emotional problems should be carefully monitored, providing prompt diagnosis and treatment as appropriate.

Positive everyday experiences interact with social support to predict depression in multiple sclerosis

Both social support and stress predict depression in multiple sclerosis (MS) patients. Little work has been done on the relationship between positive life experiences and depression in this group. Ninety MS patients completed the Social Support Questionnaire (SSQ), the Hassles and Uplifts Scale (HUS), the Chicago Multiscale Depression Inventory (CMDI), and the Affective Reading Span Task (ARST). The Expanded Disability Status Scale (EDSS) was also used. Separate regression analyses were conducted with the EDSS entered at step 1, ARST memory bias score at step 2, SSQ at step 3, either Hassles or Uplifts at step 4, and the interaction term at step 5 to predict depression. Uplifts interacted significantly with social support to predict depression, but hassles did not. After considering disability level, memory bias, and social support and uplifts main effects, the interaction of uplifts and social support accounted for nearly 5% independent variance in depression (p < .05). These results suggest that the absence of uplifts, combined with low levels of social support, is related to depression in MS patients. More generally, these data indicate that it is important to study the absence of positive experiences along with stress and negative experiences in this population.

Personality characteristics and disorders in multiple sclerosis patients: assessment and treatment

Multiple sclerosis (MS) is a major inflammatory and demyelinating disease of the central nervous system. Although a significant incidence and prevalence of psychological disorders in MS has been reported there is limited data on the prevalence of personality disorders (PD) in these patients. Recent findings indicate the need for early diagnosis and treatment of PD in MS patients in the interests of prognosis, conformity to treatment and patient's quality of life improvement. This article summarizes existing evidence on prevalence, types and diagnostic criteria of PD in MS, clinical manifestations of personality pathology or changes in MS patients, and instruments currently used for diagnosis and assessment of PD in this group of patients. Underlying mechanisms suggested as causes of personality changes in MS patients are also discussed. The article reviews therapeutic strategies, including pharmacotherapy and psychotherapy interventions and emphasizes the need for a multidisciplinary approach to patient's treatment.

Predictors of depression in multiple sclerosis patients

Depression is one of the major problems associated with multiple sclerosis (MS). Several physical and psychological factors tend to interact and make it difficult to pinpoint the predictors of the depression. It seemed particularly important to examine how anxiety and illness evolution (characterized by the functional status) influence the appearance of depression symptoms. Thus, the aim of this article was to clarify the relationship between depression and the factors associated with it. One hundred and fifteen participants living at home recruited through various associations and MS clinics answered socio demographic, medical and psychological questions and questionnaires (depression, anxiety, coping, social support, locus of control, alexithymia, self-esteem). Results show that functional status (EDSS), trait anxiety, alexithymia and satisfaction with social support system are the predicting factors of depression. Trait anxiety and functional status are two predictors that independently and simultaneously lead to the appearance of depression symptoms, with trait anxiety playing a predominant role. Alexithymia and social support indirectly influence the appearance of these symptoms.

Patients with multiple sclerosis in a war zone: coping strategies associated with reduced risk for relapse

The objective of this article is to examine the role of coping strategies in multiple sclerosis outcomes among civilians under a military attack during the 2006 war between Hezbollah and Israel. Participants were 156 patients with relapsing—remitting multiple sclerosis. We analysed the relationships between coping and emotional distress and between coping and multiple sclerosis exacerbation. We also assessed a model of the relationship between perceived stress, event-related stress, and coping with increased risk of multiple sclerosis exacerbations using multivariate logistic regression. Ways of coping and subjective stress were evaluated by means of structured interviews using questionnaires previously validated. The more distressed our respondents were during the war, the more likely they were to employ a variety of ways of coping. Correlation coefficients between coping scores and perceived war stress ranged from 0.2 to 0.44 ( p < 0.001—0.01). Correlation coefficients between the various coping scores and broader indices of distress ranged from 0.28 to 0.5 ( p < 0.001). Of the remitting patients during and following the war, 47.1% reported the use of ‘direct coping and planning’, compared to 16.7% of patients who relapsed during the same period ( p = 0.014). ‘Direct coping and planning’ was negatively related to exacerbation of multiple sclerosis symptoms (OR = 0.1, 95% CI = 0.02—0.5). The Nagelkerke R2 was 0.26. Our findings point to an association between ‘direct coping and planning’ and reduced multiple sclerosis relapse rate during wartime. Further research should explore whether the employment of specific ways of coping can reduce the risk for relapse among patients with multiple sclerosis during periods of distress.

Coping strategies, psychological variables and their relationship with quality of life in multiple sclerosis

The aim of this study was to assess the impact of psychological features in the choice of coping strategies in multiple sclerosis (MS) patients, and their influence on quality of life (QoL). One hundred four patients (72 women, age 45.3 +/- 10.9 years, disease duration 17.9 +/- 13.2 years, Expanded Disability Status Scale 2.8 +/- 2.0) were assessed through the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Eysenck Personality Questionnaire, the Coping Orientation for Problem Experiences-New Italian version and the MSQoL-54. MS patients were less likely to use problem-focused strategies, whereas avoiding strategies were adopted more frequently. The use of positive strategies positively influenced both mental and overall QoL. Depression had a negative impact on all QoL domains and anxiety on mental domains. These data point out the importance of a comprehensive assessment of MS patients. Orienting therapeutic interventions, to oppose depression and anxiety and to favour more appropriate coping strategies can improve the patients' QoL.

The impact of stressful life events on risk of relapse in women with multiple sclerosis: A prospective study

Purpose

The aims of this study were first, to examine the general relation between stressful life events (SLEs) and clinical relapses in women with multiple sclerosis (MS) and second, to investigate the relations of the specific stressor attributes of duration, type, and severity on MS exacerbations.

Methods

Twenty six ambulating women with relapsing-remitting MS were followed-up for a mean of 56.3 weeks. Patients documented SLEs weekly in self report diaries which were then collected at regular pre-scheduled clinic visits every 4 weeks. SLEs were classified as short-term if they had subjectively no lasting effect and long-term if they had a subjectively felt psychological impact that lasted at least 10–14 days after the event. The severity of SLEs was determined using the Recent Life Change Questionnaire.

Results

Experiencing three or more SLEs, during a 4-week period, was associated with a 5-fold increase of MS relapse rate (95% CI 1.7–16.4, p = 0.003). The presence of at least one long-term SLE was associated with three times (95% CI 1.01–9.13, p < 0.05) the rate of MS exacerbation during the following 4 weeks. There was no significant association between the severity (95% CI 0.99–1.01, p > 0.05) or the type (χ2 = 7.29, df = 5, p > 0.05) of stressor and the risk for relapse.

Conclusion

Ambulatory women with relapsing-remitting MS who experience cumulative SLEs may be at a greater risk for relapse. Duration is the only stress attribute that seems to increase the risk for relapsing in contrast to stress type and stress severity that were not found to interact with MS exacerbation.

Influence of anxiety and reported stressful life events on relapses in multiple sclerosis: a prospective study

Objective

Self-reported stressful life events and infections have been associated with relapses in multiple sclerosis. Also, anxiety has been reported to influence other diseases of unpredictable course. To study relation of self-reported stressful life events, levels of anxiety, and episodes of infection, with relapses of the disease in women with multiple sclerosis.

Methods

This is a one-year prospective study. Thirty seven women with multiple sclerosis were regularly seen every four weeks, for one year. They were keeping diaries of events they considered stressful. These events were ranked according to the Holmes and Rahe Social Readjustment Rating Scale. Their anxiety levels were assessed with the Hamilton rating scale for anxiety. Relapses and episodes of infection were verified at additional visits. Results were studied using a survival analysis model adapted for several recurrent events.

Results

A total of 291 stressful events, 37 episodes of infection, and 48 relapses, were registered. High level of anxiety were stongly related to the number and the severity of reported stressful events during the preceding period and with the advent of a relapse in the following period (Hamilton score greater than 18 is associated with 4.2 times the rate of relapsing and three or more reported stressful events with 5.7 times the rate of relapsing).

Conclusions

Anxiety and self-reported stressful events may in fact be two measures of the same underlying emotional factor, which plays an important role on the course of the disease, in addition to episodes of infection.

Mind over matter: cognitive - behavioral determinants of emotional distress in multiple sclerosis patients

Given the high incidence and unique symptomatology of depression in multiple sclerosis (MS) patients, the current study examined the role of cognitive and behavioral variables in predicting psychosocial adjustment in this population, in order to suggest psychotherapeutic interventions tailored specifically to MS patients. Data from 329 MS patients indicated that problem solving coping, acceptance coping, and challenge appraisals were associated with positive psychological adjustment (i.e., high life satisfaction, low depression and anxiety), whereas variables measuring disease severity (i.e., illness duration, subjective health status, and self-reported disability) were not associated with adjustment. These findings suggest that MS patients' psychological outcomes are more related to controllable cognitive and behavioral factors than to the physical effects of the disease. Consequently, it is expected that interventions that target these specific coping strategies and cognitive appraisals will be effective in treating the emotional effects of MS.

Psychological aspects of multiple sclerosis

A significant incidence and prevalence of psychological disorders in multiple sclerosis (MS) has been reported. Their underlying mechanisms and the extent to which they are reactive to psychosocial factors or symptoms of the pathological process itself, remain unclear. Depression is the predominant psychological disturbance with lifetime prevalence around 50% and annual prevalence of 20%. Depression is commoner during relapses, may exacerbate fatigue and cognitive dysfunction and no firm evidence exists of its induction by interferon; instead, treating depression improves adherence to disease-modifying drugs. Anxiety is also frequent, occurs in newly diagnosed patients, and its co-morbidity with depression has been suggested to increase the rate of suicidal ideation. The relationship between stress and MS is an attractive issue because some studies pointed to an association between stressful life-events and MS onset/relapses; however, the evidence supporting this hypothesis is not conclusive so far. Other psychiatric illnesses, as bipolar affective disorder, pathological laughing and crying or psychosis occur less frequently in MS. Therapeutic strategies include psychotherapy, cognitive behavioural therapy, strengthen of coping, and specific medications. The "art" of the MS team in providing the best individualized care is emphasized, aiming to reduce the burden of the disease and improve the patients' quality of life.

Social conflict exacerbates an animal model of multiple sclerosis

A growing body of evidence suggests that social conflict is associated with inflammatory disease onset and exacerbations in multiple sclerosis (MS) patients and in animal models of MS. This review illustrates how animal research can be used to elucidate the biobehavioral mechanisms underlying the adverse health effects of social conflict. The authors review studies indicating that social conflict exacerbates a virally initiated animal model of MS. This research suggests that the deleterious effects of social conflict may be partially mediated by stress-induced increases in pro-inflammatory cytokine levels in the central nervous system. In addition, they provide evidence that the adverse health effects of social conflict can be prevented by blocking the stress-induced increases in cytokine activity. This suggests that interventions designed to prevent or reverse the stress-induced increases in cytokine activity may be able to prevent or reverse some of the negative health effects of social conflict in humans.

Stress and multiple sclerosis

Increasing numbers of studies are reporting an association between stressful life events and exacerbation in multiple sclerosis. We review findings that begin to suggest psychological, social and biological factors that may be involved in this relationship. Depression, negative attributions, poor coping, and low social support have been implicated as aggravating the relationship between stress and exacerbation. A model of glucocorticoid resistance on immune cells is also presented as one potential biological mechanism. It is emphasized that to date there is no evidence of causal relationships. It is argued that a purely causal relationship, in which stressful events alone trigger exacerbation, is unlikely. Rather, we propose that stress may be one factor among many that influence risk of exacerbation.

Predictors of Subjective Well-being among Individuals with Multiple Sclerosis

Neuropsychological and psychosocial predictors of subjective well-being (SWB) were examined among 74 persons with multiple sclerosis (MS). The multidimensional construct of SWB was assessed by self-report measures of acute psychological distress, global life satisfaction, and health-related quality of life (HRQoL). Objective disease-related indices were obtained from medical records and neuropsychological testing. Unawareness of deficit, a frequent aspect of executive function impairments in MS, was measured as the discrepancy between patient self-report of functional abilities and a caregiver's report of the patient's abilities. Results indicate that a substantial proportion of patients experienced diminished SWB and that disease characteristics such as duration and severity have differential relationships to SWB outcomes. Multiple regression analyses indicated that, in the context of a combined predictive model, social support and unawareness of deficit provided unique information in predicting all three aspects of SWB, beyond that accounted for by disease characteristics. Both social support and unawareness of deficit were associated with positive well-being outcomes. Neuropsychological impairment was adversely related to life satisfaction and HRQoL, but it did not add unique information to the prediction of these outcomes. The findings present a unique view of SWB among individuals with MS in the absence of acute exacerbation of the illness.

Coping and quality of life in one hundred and thirty five subjects with multiple sclerosis

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.

Relationship between stress and relapse in multiple sclerosis: Part II. Direct and indirect relationships

OBJECTIVE

The aim of this two-year prospective study was to determine which factors were: (i) directly related and/or (ii) indirectly related to multiple sclerosis (MS) relapse. These factors included life-event stressors, disease, demographic, psychosocial and lifestyle factors.

BACKGROUND

Relatively little attention has been paid to the role of non-clinical relapse predictors (other than stressful life-events) in MS, or factors that indirectly impact on the stress-relapse relationship.

METHODS

A total of 101 consecutive participants with MS were recruited from two MS clinics in Sydney, Australia. Stressful life-events, depression, anxiety and fatigue were assessed at study-entry and at three-monthly intervals for two years. Disease, demographic, psychosocial and lifestyle factors were assessed at baseline. Patient-reported relapses were recorded and corroborated by neurologists or evaluated against accepted relapse criteria.

RESULTS

MS relapse was predicted by acute stressor frequency counts, coping responses that utilized social support, and being born in Australia, but not by chronic stressors, disease, demographic, psychosocial or lifestyle factors. No factors were found to indirectly impact on the stress relapse relationship.

CONCLUSIONS

The number rather than severity of stressors was most important in relation to MS relapse risk, along with coping responses that utilized social support, suggesting that MS patients should avoid situations that are likely to generate multiple stressors or which provide few avenues for social support.

A temporal framework for understanding the effects of stressful life events on inflammation in patients with multiple sclerosis

A growing literature reports that stressful life events are associated with exacerbation and the subsequent development of brain lesions in patients with multiple sclerosis (MS). The evolution an MS exacerbation occurs over a period of many months and involves many different biological processes that change over time. Likewise, the experience of stress also occurs over time, with an onset, a shift from acute to chronic in some cases, and resolution. Each of these phases is associated with unique biological features. Thus, the impact of stress on MS exacerbation may depend on the temporal trajectories of stress and MS exacerbation, and when the intersection between these two trajectories occurs. This paper presents a temporal model, along with three different temporal relationships and associated mechanisms by which stress may impact MS exacerbation. These include the onset of a stressor, which may be mediated by mast cell activation, the point that a stressor begins to become chronic, which may be mediated by glucocorticoid resistance in immune cells, and the resolution of the stressor, which may be mediated by a drop in cortisol. These three hypotheses are not necessarily mutually exclusive. Data on psychosocial mediators and moderators are also briefly reviewed and future research directions are discussed.

Mood and self-esteem of persons with multiple sclerosis following an exacerbation

OBJECTIVE

This study was designed to determine the impact of an exacerbation in the symptoms of multiple sclerosis (MS) on the mood and self-esteem of persons with MS over an 18-month period.

METHODS

Participants were 243 (80 males and 163 females) persons with MS and 184 (56 males and 128 female) persons from the general population. Information was obtained about coping styles, mood, and self-esteem among all respondents at Time 1, Time 2 (6 months later), and Time 3 (18 months later).

RESULTS

The results demonstrated that both groups of persons with MS experienced poorer mood levels than the general population, with the exacerbation group showing the highest levels of anxiety and confusion. Coping strategies did not predict mood in either of the MS groups.

CONCLUSION

The findings of this study demonstrate that persons with MS experience significant problems with their mood states. However, respondents need to be tracked over a longer period to further explore the role of coping strategies in the adjustment of persons with MS.

Depression and fatigue in relapsing-remitting MS: the role of symptomatic variability

Depression and fatigue are common psychosocial sequelae of MS. An infrequently examined issue in the MS literature is the effect of MS-related symptom variability on incidence of depression and fatigue. The current study was designed to examine the relationship of variability in physical, cognitive, and social/environmental functioning with depression and fatigue in MS. Forty-eight relapsing-remitting MS patients from a larger sample completed self-report measures of depression and fatigue. They were also administered a structured interview that assessed current, best, and worst levels of functioning since being diagnosed with MS. Higher levels of symptom variability since disease onset were associated with depression and fatigue, even after accounting for MS-related physical disability. Regression analyses indicated that variability in social and environmental functioning was particularly associated with depression, and variability in physical abilities was associated with fatigue. These findings suggest that a more variable course of MS symptoms is associated with increased depression and fatigue. Focused assessment of variability in symptoms may be useful in detecting and subsequently treating depression and fatigue in MS patients.

Exercise and Rehabilitation for Individuals with Multiple Sclerosis

It is the coexistence of physical and cognitive impairments, together with emotional and social issues in a disease with an uncertain course, that makes MS rehabilitation unique and challenging. Inpatient rehabilitation improves functional independence but has only limited success improving the level of neurologic impairment. Benefits are usually not long lasting. Severely disabled people derive equal or more benefit than those who are less disabled, but cognitive problems and ataxia tend to be refractory. There is now good evidence that exercise can improve fitness and function for those with mild MS and helps to maintain function for those with moderate to severe disability. Therapy can be performed over 6 to 15 weeks in outpatient or home-based settings or as a weekly day program lasting several months. Several different forms of exercise have been investigated. For most individuals, aerobic exercise that incorporates a degree of balance training and socialization is recommended. Time constraints, access, impairment level, personal preferences, motivations, and funding sources influence the prescription for exercise and other components of rehabilitation. Just as immunomodulatory drugs must be taken on a continual basis and be adjusted as the disease progresses, so should rehabilitation be viewed as an ongoing process to maintain and restore maximum function and QOL.

Health Promotion in People with Multiple Sclerosis

Chronic diseases like MS present unique challenges and opportunities for patients and the medical care system. Patients are challenged because they are under tremendous pressure to actively engage themselves in multiple prevention, treatment, and health maintenance behaviors, often before they feel ready. Health care providers are challenged because health-promotion activities require more time, counseling skills, and organizational resources than traditional, acute medical care. Patients, clinicians, and researchers face the challenge of determining which health-promotion activities are not only supported by the evidence but also appropriate for a given patient. New models of health promotion are being developed that integrate self-help and professional help. These approaches have been applied in other chronic diseases and should be adapted and studied among people with MS.

The stress of being chronically ill: from disease-specific to task-specific aspects

The assumption that disease-related stressors are exclusive for particular diagnoses characterizes many studies of chronically ill patients. In this study the perceptions of 1305 patients from 10 different chronic disease categories were compared with respect to a number of important stressors. Differences were found in the amount and type of stressors experienced, but these differences could not solely be explained by type of disease. Personal characteristics such as age, sex, education level, living situation, and illness duration were also important in determining the degree and type of stress experienced. The implications of these findings for stress/coping research as well as the clinical implications are discussed.

Alterations in chemokine expression following Theiler's virus infection and restraint stress

Restraint stress (RS) applied to mice during acute infection with Theiler's virus causes corticosterone-induced immunosuppression. This effect was further investigated by measuring chemokine changes in the spleen and central nervous system (CNS) using an RNase Protection Assay. mRNAs for lymphotactin (Ltn), interferon-induced protein-10 (IP-10), MIP-1 beta, monocyte chemoattractant protein-1 (MCP-1) and TCA-3 were detected in the spleen at day 2 pi, but not in the brain of CBA mice infected with Theiler's virus. Ltn, IP-10 and RANTES were elevated in both the spleen and the brain at day 7 pi, and were significantly decreased by RS in the brain. RS also resulted in decreased inflammation within the CNS.

Association between stressful life events and exacerbation in multiple sclerosis: a meta-analysis

OBJECTIVE

To quantify the association between stressful life events and exacerbations of multiple sclerosis.

DATA SOURCES

PubMed, PsychInfo, and Psychological Abstracts searched for empirical papers from 1965 to February 2003 with terms "stress", "trauma", and "multiple sclerosis".

REVIEW METHODS

Three investigators independently reviewed papers for inclusion/exclusion criteria and extracted the relevant data, including methods, sample statistics, and outcomes.

RESULTS

Of 20 studies identified, 14 were included. The meta-analysis showed a significant increase in risk of exacerbation in multiple sclerosis after stressful life events, with a weighted average effect size of d = 0.53 (95% confidence interval 0.40 to 0.65), P < 0.0001. The studies were homogenous, Q = 16.62, P = 0.22, I2 = 21.8%. Neither sampling nor study methods had any effect on study outcomes.

CONCLUSIONS

There is a consistent association between stressful life events and subsequent exacerbation in multiple sclerosis. However these data do not allow the linking of specific stressors to exacerbations nor should they be used to infer that patients are responsible for their exacerbations. Investigation of the psychological, neuroendocrine, and immune mediators of stressful life events on exacerbation may lead to new behavioural and pharmacological strategies targeting potential links between stress and exacerbation.

Coping and psychological adjustment among people with multiple sclerosis

OBJECTIVE

This study was concerned with examining the coping and psychological adjustment of people with multiple sclerosis (MS) and determining how they were different in these dimensions from people from the general population. The role of severity and duration of illness as well as levels of social support on coping style and adjustment were also evaluated.

METHOD

The participants were 381 (144 men, 237 women) people with MS and 291 (101 men, 190 women) people from the general population.

RESULTS

The results demonstrated that people with MS (particularly men) were less likely to adopt coping styles related to problem solving and seeking support and demonstrated poorer levels of adjustment on all dimensions. Adopting a wishful thinking coping style, as well as a lack of problem-focused coping or failure to seek social support, was also more likely to be associated with poorer psychological adjustment for both men and women with MS. Levels of health impairment were only minimally related to psychological adjustment, particularly for men.

DISCUSSION

These findings highlight the importance of developing educational programs that include strategies to adopt more problem-focused coping strategies, so that people with MS can more readily adjust to their illness.

Does trauma trigger multiple sclerosis? 1: A controversy

The potential role of trauma in the development of multiple sclerosis is important but controversial. Patients commonly ask about this and it has important medicolegal ramifications. In addressing such issues this article will consider both physical and psychological trauma, examine pathogenic mechanisms, and discuss the evidence for and against a relationship.

Self reported stressful life events and exacerbations in multiple sclerosis: prospective study

OBJECTIVE

To study the relation between self reported stressful life events not related to multiple sclerosis and the occurrence of exacerbations in relapsing-remitting multiple sclerosis.

DESIGN

Longitudinal, prospective cohort study.

SETTING

Outpatient clinic of department of neurology in the Netherlands.

PARTICIPANTS

Patients aged 18-55 with relapsing-remitting multiple sclerosis, who could walk with a cane or better (score of 0-6.0 on the expanded disability status scale), and had had at least two exacerbations in 24 months before inclusion in the study. Patients with other serious conditions were excluded.

MAIN OUTCOME MEASURE

The risk of increased disease activity as measured by the occurrence of exacerbations after weeks with stressful events.

RESULTS

Seventy out of 73 included patients (96%) reported at least one stressful event. In total, 457 stressful life events were reported that were not related to multiple sclerosis. Average follow up time was 1.4 years. Throughout the study, 134 exacerbations occurred in 56 patients and 136 infections occurred in 57 patients. Cox regression analysis with time dependent variables showed that stress was associated with a doubling of the exacerbation rate (relative risk 2.2, 95% confidence interval 1.2 to 4.0, P = 0.014) during the subsequent four weeks. Infections were associated with a threefold increase in the risk of exacerbation, but this effect was found to be independent of experienced stress.

CONCLUSION

Stressful events were associated with increased exacerbations in relapsing-remitting multiple sclerosis. This association was independent of the triggering effect of infections on exacerbations of multiple sclerosis.

2002 Robert Ader New Investigator award. Relationship of cardiovascular reactivity, stressful life events, and multiple sclerosis disease activity

Previous studies of stress in multiple sclerosis patients have suggested that life events may alter the onset and development of MS. However, results have been inconsistent because of infrequent monitoring and reporting bias. We followed fifty female MS patients for 1 year to determine characteristics of life events associated with MS exacerbations, and examine the influence of cardiovascular activity. Subjects completed weekly life-event checklists. The short- and long-term threat of each event was determined using the Life Events and Difficulties Schedule. Neurologic symptoms were also monitored weekly. MS exacerbations were confirmed by a neurologist blinded to psychosocial events. Cardiovascular reactivity to an acute psychological stressor was determined at study onset, and resting heart rate and blood pressure were monitored monthly. Forty-two percent of life events were associated with exacerbations in the subsequent 6 weeks. Logistic regression confirmed that exacerbations were more likely during at-risk periods following life events and were relatively independent of the threat level and type of stressor. Participants with higher cardiovascular reactivity to acute stress and higher baseline heart rate demonstrated a greater number of exacerbations and proportion of weeks ill. Using multiple regression, we found that disability level, medication usage, cardiovascular reactivity, baseline heart rate, and life event density explained approximately 30% of the variance in the proportion of weeks ill. These results are consistent with the hypothesis that stress is a potential trigger of MS disease activity and suggest that autonomic tone and stress reactivity may play a role in the development of stress-related exacerbations.

Effects of psychological group therapy in patients with multiple sclerosis

OBJECTIVES

The aim of this pilot study was to evaluate a psychological therapy program used in the treatment of multiple sclerosis (MS) and including cognitive/behavioral strategies, relaxation training and physical exercise.

MATERIAL AND METHODS

The participants were 29 patients with MS recruited from an outpatient unit; 14 patients were assigned to the 7-week psychological therapy group (one session per week), the remainder formed a control group. Before and immediately after the course of therapy and after a 2-month follow-up, the participants completed a series of questionnaires measuring factors such as depression, anxiety, coping and body image.

RESULTS

Compared with the control group the therapy group showed long-term improvements in depressive stress coping style and a short-term improvement in "vitality and body dynamics".

CONCLUSION

Further studies should investigate the differential effects of specific units of the therapy program and how the short-term improvements in "vitality and body dynamics" could be maintained for longer periods.
