Emotional stress and coping in multiple sclerosis (MS) exacerbations

TNF-alpha and psychologically stressful events in healthy subjects: potential relevance for multiple sclerosis relapse

The authors conducted a prospective and descriptive pilot study in 14 healthy medical students, investigating whether a psychologically stressful event (final examination) may modify serum tumor necrosis factor alpha (TNF-alpha) levels. There was a dramatic and sustained decrease of phytohemagglutinin (PHA)-induced TNF-alpha several weeks before and the day of the examination, followed by a significant increase of TNF-alpha starting the next day. Examination-induced stress was confirmed by both elevated urinary cortisol concentration and significant increase in stress scale scores. Extending these results to patients suffering from multiple sclerosis (MS) leads to the hypothesis that psychological stress may influence the course of MS by substantially altering TNF-alpha levels, and suggests the need for further studies in MS patients exposed to stressful conditions.

Moderating effects of coping on the relationship between stress and the development of new brain lesions in multiple sclerosis

OBJECTIVE

Many patients with multiple sclerosis (MS) report that stress can trigger disease exacerbations. Considerable research has supported a relationship between stress and both clinical exacerbation and the development of new brain lesions. However, these relationships are not always consistent either within patients or across patients, suggesting the presence of moderators. This study examined the hypothesis that coping moderates the subsequent relationship between stress and the development of new brain lesions in MS.

METHODS

Thirty-six patients (mean age = 44.4; 22 women, 14 men) with relapsing forms of MS were assessed once every 4 weeks for 28-100 weeks. New brain lesions were identified using monthly Gd+ MRI. Stress was measured within 24 hours before MRI using a modified version of the Social Readjustment Rating Scale that assessed Conflict and Disruption in Routine. Coping was measured at baseline using the Coping with Health Injuries and Problems questionnaire, which produces four scales: distraction, instrumental, palliative, and emotional preoccupation. Data were analyzed using mixed effects logistic regression to account for within-subject correlations. Analyses were lagged such that stress assessments predicted new Gd+ MRI brain lesions 8 weeks later.

RESULTS

As reported previously, stress was significantly related to the development of new Gd+ brain lesions 8 weeks later (OR = 1.62, p =.009). Greater use of distraction was found to be a significant moderator of the relationship between stress and new Gd+ lesions (OR = 0.69, p =.037) such that greater use of distraction was associated with a decreased relationship between stress and new Gd+ lesions. Increased instrumental coping was marginally associated with a decreased relationship between stress and new Gd+ lesions (OR = 0.77, p =.081), while increased emotional preoccupation was marginally associated with an increased relationship between stress and new Gd+ lesions (OR = 1.46, p =.088). There was no significant moderating effect for palliative coping (p =.27) and no significant main effects for any coping variables and the subsequent development of new Gd+ brain lesions (p values >.21).

CONCLUSIONS

These findings provide modest support for the hypothesis that coping can moderate the relationship between stress and the MS disease activity. Several limitations in this study are discussed. While these findings suggest areas of potentially fruitful research, readers are cautioned that these are preliminary results; inferences regarding the clinical importance of these findings are premature.

Depression during exacerbations in multiple sclerosis: the importance of uncertainty

The following correlates of depression were examined in a sample of 166 patients with clinically definite relapsing-remitting (n=140) or secondary progressive (n=26) multiple sclerosis: (a) the present state of the patients' illness (i.e., whether or not they were currently experiencing an exacerbation of their symptoms); (b) their level of uncertainty concerning their illness; and (c) their strategies for coping with their illness. A current exacerbation in symptoms, greater uncertainty of illness, and greater use of emotion-centered forms of coping were all related to depression. Multivariate analyses revealed that uncertainty of illness played a pivotal role as a mediating variable. Exacerbations in illness appeared to heighten patients' levels of uncertainty, and it was largely through this heightened uncertainty that the increases in depression came about.

Multiple sclerosis: empirical literature for the clinical health psychologist

This article reviews the empirical literature related to clinical health psychology in multiple sclerosis (MS). MS is a disease in which the immune system attacks the central nervous system. As such, the interactions between medical and psychological variables are complex, and potentially of considerable importance to patients. Common neuropsychological and psychological problems associated with MS and their etiologies are reviewed. The effects of stress and depression on MS exacerbation are discussed, including clinical, immune, endocrine, and neuroimaging findings. The types of coping common in MS and their effects on adjustment are discussed. The empirical literature on psychological and neuropsychological intervention is reviewed. The small literature on caregiving in MS is also summarized.

Psychological stress and the subsequent appearance of new brain MRI lesions in MS

OBJECTIVE

To examine the relationship between stressful life events and psychological distress, and the subsequent development of gadolinium-enhancing (Gd+) brain lesions.

BACKGROUND

It has long been speculated that stressful life events and psychological distress are associated with disease exacerbation in MS. This is the first prospective longitudinal study of the relationship between stressful life events, psychological distress, and disease activity as measured by Gd+ brain MRI.

METHODS

Thirty-six patients (mean age, 44.4 years; 22 women, 14 men) with relapsing forms of MS were assessed once every 4 weeks for 28 to 100 weeks. Assessments included Gd+ MRI, the Social Readjustment Rating Scale (SRRS), the Hassles Scale, and the Profile of Mood States. The SRRS was altered in the following manner: 1) three items that confounded with MS were eliminated, 2) endorsed items were rated for intensity, and 3) the scale was divided into three subscales: major negative events, conflict and disruption in routine, and positive life events. Data were analyzed using mixed-effects logistic regression to account for intrasubject correlations. Stress and distress measures were used to predict concurrent and future MRI activity.

RESULTS

For the total sample of patients, increased conflict and disruption in routine was followed by increased odds of developing new Gd+ brain lesions 8 weeks later (odds ratio, 1.64; p = 0.00083). There was no strong evidence of a relationship between psychological stress or distress and clinical exacerbation.

CONCLUSIONS

These data provide support for the notion that conflict and disruption in routine are related to subsequent disease activity in MS. However, this relationship is not sufficiently robust to predict clinical exacerbations reliably in individual patients.

Stress and course of disease in multiple sclerosis

In this prospective study, 96 healthy controls and 101 multiple sclerosis patients were followed up for as many as 6 years, and self-reported stressful events and health status were assessed. The authors evaluated (a) whether patients reported more stressful life events than healthy controls and (b) the bidirectional relationship between stress and functional deterioration among patients. Healthy controls reported more life events than patients, Odds ratio (OR) = 1.13, p < .0001; and this relationship was attributable to healthy controls' reporting more neutral/positive events than patients. A bidirectional relationship was confirmed between stress and illness: there was an increased risk of disease progression when rate of reported stressful events was higher, OR = 1.13, p < .0003, and an increased risk of reported stressful events when rate of disease progression was higher, OR = 2.13, p < .0001. There were no differences in reported stress by level of baseline disability. The authors concluded that multiple sclerosis patients demonstrate a vicious cycle between stress and disease progression.

Optimism and adaptation to multiple sclerosis: what does optimism mean?

The aim of the present study was to determine the meaning of optimism by explicating the dimensions underlying the notion and their links to adjusting to MS. Seventy-three patients responded to optimism questionnaires (i.e., the LOT, Generalized Self-Efficacy Scale) and outcome questionnaires. In confirmatory factor analyses, the underlying dimensions of optimism were specified. Explanatory structural equation modeling was used to examine the relation of the dimensions of optimism to coping (CISS), depression (BDI), and impaired mobility range (SIP). Optimism was found to consist of three dimensions, namely, outcome expectancies, efficacy expectancies, and unrealistic thinking. Outcome and efficacy expectancies explained depression via emotion-oriented coping but did not explain impaired mobility range either directly or indirectly. Unrealistic thinking directly explained impaired mobility range. The present study can be seen as a first step in explicating the role of optimism in the management of chronic disease.

Stress and coping in multiple sclerosis: exacerbation, remission and chronic subgroups

Individuals with multiple sclerosis were asked to identify stressors they had experienced over a 6-month period and the coping mechanisms employed to deal with those stressors. Subjects who reported currently experiencing an exacerbation of symptoms were compared with those in remission or in the chronic phase of their illness. Of the 61 subjects who completed the Hassles Scale, Uplifts Scale, and Ways of Coping, those classified as being in an exacerbation phase of MS were found to have significantly higher hassles scores than those in the chronic phase. A significant difference was also found in terms of a factor labeled 'passive avoidant and aggressive coping' derived through a factor analysis of the Ways of Coping subscales. Subjects in the exacerbation subgroup had higher scores on this coping factor than those in the chronic subgroup. The difference in hassles scores remained significant after between-group differences in length of illness and reported number of symptoms were controlled through an analysis of covariance, although the difference in coping fell short of significance in this covariance analysis.

Affective disorders and multiple sclerosis: a controlled study on 65 Italian patients

A high prevalence of major mood disorders in multiple sclerosis (MS) patients has been reported. In this study, we investigated the frequency of previous or present major mood disorders in 65 patients with clinically definite multiple sclerosis (Poser criteria) and in 31 polyneuropathy (PNP) patients. All patients underwent a questionnaire designed after DSM-IV definitions for major mood disorders. A higher lifetime risk for development of a major mood disorder was evident in MS patients (log rank test, p<0.001). Of all MS patients with a major mood disorder, at least 34% had one first-degree relative affected by a mood disorder, while the corresponding figure was 14% among PNP cases. Our data confirm the high lifetime risk for depression in MS patients and suggest that, at least in a subset of MS patients with depression, the genetic basis for depression operates with similar mechanisms as those at work in families with primary depression. However, this is not necessarily true for other subsets of depressed MS patients' families.

Neuropsychological aspects of multiple sclerosis

Since S. Rao's ["Neuropsychology of Multiple Sclerosis: A Critical Review," A Journal of Clinical and Experimental Neuropsychology, Vol. 85, pp. 503-542] (1986) seminal review, considerable research has been undertaken on the neuropsychological consequences of multiple sclerosis. This review incorporates the research literature of the last decade in presenting an overview of the current state of our knowledge concerning the etiology, course, symptoms, assessment, consequences, and treatment of multiple sclerosis (MS). The concept of subcortical dementia is revisited in light of the most recent literature documenting the neuropsychological deficits in patients with MS. The view that cognitively heterogeneous patient groups may disguise more specific patterns of focal neuropsychological impairment is considered. A critical review of the recent literature is also presented, detailing the degree to which recent research has addressed the areas of research need identified by Rao in 1986. Given recent advances in our knowledge, the need for more attention to be directed toward the evaluation of rehabilitation and psychological intervention is highlighted.

Symptom and activities of daily living trajectory in multiple sclerosis: a 10-year study

BACKGROUND

Symptom control in chronic illness is not merely a matter of medical management as the patient and family must rely on their own judgment, wisdom, and ingenuity for controlling symptoms. The absence in the literature regarding the effects of multiple sclerosis (MS) as perceived by afflicted people and their family members led to the 10-year longitudinal study.

OBJECTIVES

To study patient self-report data to determine whether particular interventions may be needed to enhance the individual's comfort and functional levels.

METHODS

The chronic illness trajectory of three groups of people with MS (< or =5 years of diagnosis, n=49; >5 to 10 years, n=36; and >10 years, n=68) was examined over a 10-year period. Serial self-assessments of the subjects' prevalence of MS-related symptoms (motor, brain stem, sensory, elimination, mental/emotional) and level of activities of daily living (ADL) functioning (fine and gross motor activities, sensory/communication, socializing/recreation, intimacy) were obtained annually. Profiles illustrating the subject's symptom and ADL pattern were also returned annually to each subject.

RESULTS

Using 10-year average scores, study findings indicated no group differences relative to symptoms but showed significant group differences in all ADL functions. Separate group within-year (1, 3, 5, 7, 10) comparisons reflected significant increases in motor, brain stem, and elimination symptoms together with a decline in all ADL functions for specific groups.

CONCLUSIONS

Medical data suggest, on average, a continuous downward trajectory beginning in the first years of illness or at approximately 36 to 37 years of age. In contrast, in this research, patient self-reports of fine and gross motor ADL, a correlate of neurologically based disability evaluations, reflect that relatively major decline begins after 5 years post-diagnosis and after age 40 for subjects recruited primarily from nonclinical sites.

Sense making in multiple sclerosis: the information needs of people during an acute exacerbation

Chronic illness has been described as a major disruption in one's everyday life. Studies have shown that people seek and use information to help them cope with their disease. Using the micro-moment time-line interview technique, this study focused on the information needs of people with multiple sclerosis (MS) who had recently experienced an exacerbation of their disease. The results revealed gaps in people's knowledge about physical symptoms they were experiencing, emotions they felt, and drugs. Various sources of and barriers to obtaining information were identified. The results suggest that health professionals need to be aware of the continuing need for relevant, current, and specific information to help people with MS retain their independence and to empower them to make informed decisions.

Rehabilitation in multiple sclerosis: the potential nursing contribution

This article, the second in a series focusing on aspects of rehabilitation, considers the potential nursing role in relation to multiple sclerosis (MS). It begins with a brief description of the experience of MS as recounted by the individuals affected, which is then contrasted with current interventions which focus primarily on physical aspects of care. A number of areas of potential improvement are outlined, together with suggestions for a more comprehensive nursing role.

Assessing illness-related stress in psoriasis: the psychometric properties of the Psoriasis Life Stress Inventory

The purpose of the present study was to undertake a clinical and psychometric reappraisal of the Psoriasis Life Stress Inventory (PLSI). Total PLSI score was inversely related to age of onset of psoriasis, but bore no significant relationship to duration or to clinical severity. Similarly, patients' stress score did not differ with regards to the nature of their current treatment, to their beliefs as to what was responsible for exacerbation or improvement of their condition, or to the patients' gender. Factor analysis extracted two factors which suggested that the psychosocial impact of psoriasis results from stress associated with: (i) engaging in anticipatory/avoidance coping behavior that is effected to limit the sociocognitive intrusiveness of psoriasis; and (ii) stress resulting from patients' beliefs or actual experiences of being evaluated by others solely on the basis of their skin. The internal reliability of the scale can be improved by the deletion of three items. Revision of the PLSI is recommended to render it psychometrically and clinically acceptable for use in the UK.

Beliefs on coping with illness: a consumer's perspective

This article discusses the results of a study on beliefs on coping with illness and coping with the health care system. Using the concept mapping method, members of patient organizations (n = 172) sorted their beliefs on coping with illness and coping with the health care system into two dimensions (priority and content). Statistical analysis reveals eight beliefs on coping with illness, with "autonomy" and "acceptance of illness" as the most important. It also reveals eight beliefs on coping with the health care system, of which the most important is a professional relationship with the physician based on mutual trust and respect between two equal partners. It is argued that these beliefs represent idealized images of coping with illness and coping with the health care system. In relation to the political debate on responsible use of the health care system in Western countries, these findings show many patients are willing to act as responsible consumers of health care, that is, if providers of health care create an environment in which patients receive guidance in determining alternatives.
