The neural correlates of fatigue: an exploratory imaginal fatigue provocation study in chronic fatigue syndrome

Abstract:

BACKGROUND: Fatigue is the central symptom in chronic fatigue syndrome (CFS) and yet very little is known about its neural correlates. The aim of this study was to explore the functional brain response, using functional magnetic resonance imaging (fMRI), to the imaginal experience of fatigue in CFS patients and controls.

METHOD: We compared the blood oxygen level dependent (BOLD) responses of 12 CFS patients and 11 healthy controls to a novel fatigue provocation procedure designed to mimic real-life situations. A non-fatiguing anxiety-provoking condition was also included to control for the non-specific effects of negative affect.

RESULTS: During the provocation of fatigue, CFS patients reported feelings of both fatigue and anxiety and, compared to controls, they showed increased activation in the occipito-parietal cortex, posterior cingulate gyrus and parahippocampal gyrus, and decreased activation in dorsolateral and dorsomedial prefrontal cortices. The reverse pattern of findings was observed during the anxiety-provoking scenarios.

CONCLUSIONS: The results may suggest that, in CFS patients, the provocation of fatigue is associated with exaggerated emotional responses that patients may have difficulty suppressing. These findings are discussed in relation to the cognitive-behavioural model of CFS.

Chronic fatigue syndrome: an approach combining self-management with graded exercise to avoid exacerbations

Abstract:

Controversy regarding the aetiology and treatment of patients with chronic fatigue syndrome continues among the medical professions. The Cochrane Collaboration advises practitioners to implement graded exercise therapy for patients with chronic fatigue syndrome using cognitive behavioural principles. Conversely, there is evidence that exercise can exacerbate symptoms in chronic fatigue syndrome, if too-vigorous exercise/activity promotes immune dysfunction, which in turn increases symptoms.

When designing and implementing an exercise programme for chronic fatigue syndrome it is important to be aware of both of these seemingly opposing viewpoints in order to deliver a programme with no detrimental effects on the pathophysiology of the condition.

Using evidence from both the biological and clinical sciences, this paper explains that graded exercise therapy for people with chronic fatigue syndrome can be undertaken safely with no detrimental effects on the immune system. Exercise programmes should be designed to cater for individual physical capabilities and should take into account the fluctuating nature of symptoms.

In line with cognitive behaviourally and graded exercise-based strategies, self-management for people with chronic fatigue syndrome involves encouraging patients to pace their activities and respect their physical and mental limitations, with the ultimate aim of improving their everyday functioning.

Efficacy of cognitive behavioral therapy for adolescents with chronic fatigue syndrome: long-term follow-up of a randomized, controlled trial

Abstract:

OBJECTIVES: The purpose of this work was to assess the long-term outcome of adolescents with chronic fatigue syndrome who received cognitive behavioral therapy and to determine the predictive value of fatigue severity and physical impairments of the adolescent and the fatigue severity of the mother at baseline for the outcome of the treatment at follow-up.

PATIENTS AND METHODS: Sixty-six adolescent patients with chronic fatigue syndrome who previously participated in a randomized, controlled trial that showed that cognitive behavioral therapy was more effective than a waiting-list condition in reducing fatigue and improving physical functioning were contacted for a follow-up assessment. Fifty participants of the follow-up study had received cognitive behavioral therapy for chronic fatigue syndrome (32 formed the cognitive behavioral therapy group in the original trial, and 18 patients received cognitive behavioral therapy after the waiting period). The remaining 16 patients had refused cognitive behavioral therapy after the waiting period. The main outcome measures were fatigue severity (Checklist Individual Strength), physical functioning (Short-Form General Health Survey), and school attendance.

RESULTS: Data were complete for 61 patients at follow-up (cognitive behavioral therapy group: 47 patients; no-treatment group: 14 patients). The mean follow-up time was 2.1 years. There was no significant change in fatigue severity between posttreatment and follow-up in the cognitive behavioral therapy group. There was a significant further increase in physical functioning and school attendance (10% increase). The adolescents in the cognitive behavioral therapy group were significantly less fatigued and significantly less functionally impaired and had higher school attendance at follow-up than those in the no-treatment group. Fatigue severity of the mother was a significant predictor of treatment outcome.

CONCLUSIONS: The positive effects of cognitive behavioral therapy in adolescents with chronic fatigue syndrome are sustained after cognitive behavioral therapy. Higher fatigue severity of the mother predicts lower treatment outcome in adolescent patients.

Implementing cognitive behavioral therapy for chronic fatigue syndrome in a mental health center: a benchmarking evaluation

Abstract:

OBJECTIVE: This study evaluated the success of implementing cognitive behavioral therapy (CBT) for chronic fatigue syndrome (CFS) in a representative clinical practice setting and compared the patient outcomes with those of previously published randomized controlled trials (RCTs) of CBT for CFS.

METHOD: The implementation interventions were the following: spreading information about the new treatment setting to general practitioners and CFS patients; training mental health center (MHC) therapists in CBT for CFS; and organizing changes in the MHC patient workflow. Patient outcomes were documented with validated self-report measures of fatigue and physical functioning before and after treatment. The comparison of the treatment results with RCT results was done following the benchmark strategy.

RESULTS: One-hundred forty-three CFS patients were referred to the MHC, of whom 112 started treatment. The implementation was largely successful, but a weak point was the fact that 32% of all referred patients dropped out shortly after or even before starting treatment. Treatment effect sizes were in the range of those found in the benchmark studies.

CONCLUSIONS: CBT for CFS can successfully be implemented in an MHC. Treatment results were acceptable, but the relatively large early dropout of patients needs attention.

Efficacy of cognitive behavioral therapy for chronic fatigue syndrome: a meta-analysis

Abstract:

A meta-analysis of the efficacy of cognitive behavioral therapy (CBT) in treating chronic fatigue included 15 effect sizes for between-group outcome comparisons. Across analyses, which included a total of 1371 participants, there was a significant difference, d=0.48, in post-treatment fatigue between participants receiving CBT and those in control conditions. Results indicate that CBT for chronic fatigue syndrome tends to be moderately efficacious. Dropout rates in CBT varied from 0-42%, with a mean of 16%. In the five studies that reported the number of CBT clients who were no longer in the clinical range with regard to fatigue at the latest follow-up, the percentage varied from 33% to 73% of those assigned to CBT, with a mean of 50%. Moderator results suggest directions for future investigations.

Chronic fatigue syndrome in a 15-year-old girl

Abstract:

Fatigue and lack of energy are frequent symptoms in children and adolescents. A diagnosis of chronic fatigue syndrome should be considered in children and adolescents who complain of chronic fatigue associated with other symptoms without a demonstrable physical cause. Lack of knowledge about this syndrome and late diagnosis may have a negative impact on the normal development of affected children and adolescents. Treatment should be based on a rehabilitation program with cognitive behavioral therapy and a gradual increase in activities.

Overview of psychiatric therapy for chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome (CFS) is recognized as a special condition based on abnormality of psycho-neuro-endocrine-immunological system, which is caused by several cytokines and autoantibodies. For CFS diagnosis, it is required to exclude psychiatric diseases which could cause chronic fatigue. On the other hand, recent studies proved the effectiveness cognitive behavioral therapy(CBT) for CFS. Distorted cognition relevant to CFS includes the characteristics such as over adaptation, perfectionism, avoidance and so on. In the CBT for CFS, it is important to quit seeking physical causes, to accept the pathological state as it is, to monitor daily activity and recognize the cognitive and behavioral patterns which might prolong fatigue, to maintain a constant activity level and to make planned increases in activity.

Is cognitive behaviour therapy for chronic fatigue syndrome also effective for pain symptoms?

Abstract:

Patients with chronic fatigue syndrome (CFS) frequently report chronic pain symptoms. Cognitive behavioural therapy (CBT) for CFS results in a reduction of fatigue, but is not aimed at pain symptoms. In this study, we tested the hypothesis that a successful treatment of CFS can also lead to a reduction of pain. The second objective was to explore possible mechanisms of changes in pain. The third objective was to assess the predictive value of pain for treatment outcome. Data from two previous CBT studies were used, one of adult CFS patients (n=96) and one of adolescent CFS patients (n=32).

Pain severity was assessed with a daily self-observation list at baseline and post-treatment. The location of pain in adults was assessed with the McGill Pain Questionnaire (MPQ). Patients were divided into recovered and non-recovered groups. Recovery was defined as reaching a post-treatment level of fatigue within normal range. Recovered adult and adolescent CFS patients reported a significant reduction of pain severity compared to non-recovered patients. Recovered adult patients also had fewer pain locations following treatment. The decrease in fatigue predicted the change in pain severity. In adult patients, a higher pain severity at baseline was associated with a negative treatment outcome.

Is a full recovery possible after cognitive behavioural therapy for chronic fatigue syndrome?

Abstract:

BACKGROUND: Cognitive behavioural therapy (CBT) for chronic fatigue syndrome (CFS) leads to a decrease in symptoms and disabilities. There is controversy about the nature of the change following treatment; some suggest that patients improve by learning to adapt to a chronic condition, others think that recovery is possible. The objective of this study was to find out whether recovery from CFS is possible after CBT.

METHODS: The outcome of a cohort of 96 patients treated for CFS with CBT was studied. The definition of recovery was based on the absence of the criteria for CFS set up by the Center for Disease Control (CDC), but also took into account the perception of the patients’ fatigue and their own health. Data from healthy population norms were used in calculating conservative thresholds for recovery.

RESULTS: After treatment, 69% of the patients no longer met the CDC criteria for CFS. The percentage of recovered patients depended on the criteria used for recovery. Using the most comprehensive definition of recovery, 23% of the patients fully recovered. Fewer patients with a co-morbid medical condition recovered.

CONCLUSION: Significant improvement following CBT is probable and a full recovery is possible. Sharing this information with patients can raise the expectations of the treatment, which may enhance outcomes without raising false hopes.

Protocol for the PACE trial: a randomised controlled trial of adaptive pacing, cognitive behaviour therapy, and graded exercise, as supplements to standardised specialist medical care versus standardised specialist medical care alone for patients with the chronic fatigue syndrome/myalgic encephalomyelitis or encephalopathy

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS, also called myalgic encephalomyelitis /encephalopathy or ME) is a debilitating condition with no known cause or cure. Improvement may occur with medical care and additional therapies of pacing, cognitive behavioural therapy and graded exercise therapy. The latter two therapies have been found to be efficacious in small trials, but patient organisations surveys have reported adverse effects. Although pacing has been advocated by patient organisations, it lacks empirical support. Specialist medical care is commonly provided but its efficacy when given alone is not established. This trial compares the efficacy of the additional therapies when added to specialist medical care against specialist medical care alone.

METHODS: 600 patients, who meet operationalised diagnostic criteria for CFS, will be recruited from secondary care into a randomised trial of four treatments, stratified by current co morbid depressive episode and different CFS/ME criteria. The four treatments are standardised specialist medical care either given alone, or with adaptive pacing therapy or cognitive behaviour therapy or graded exercise therapy. Supplementary therapies will involve fourteen sessions over 23 weeks and a booster session at 36 weeks. Outcome will be assessed at 12, 24, and 52 weeks after randomisation. Two primary outcomes of self-rated fatigue and physical function will assess differential effects of each treatment on these measures. Secondary outcomes include adverse events and reactions, subjective measures of symptoms, mood, sleep and function and objective measures of physical activity, fitness, cost-effectiveness and cost-utility. The primary analysis will be based on intention to treat and will use logistic regression models to compare treatments. Secondary outcomes will be analysed by repeated measures analysis of variance with a linear mixed model. All analyses will allow for stratification factors. Mediators and moderators will be explored using multiple linear and logistic regression techniques with interactive terms, with the sample split into two to allow validation of the initial models. Economic analyses will incorporate sensitivity measures.

DISCUSSION: The results of the trial will provide information about the benefits and adverse effects of these treatments, their cost-effectiveness and cost-utility, the process of clinical improvement and the predictors of efficacy.
