Mood volatility with rumination but neither attentional nor interpretation biases in chronic fatigue syndrome

Abstract:

OBJECTIVES: This study tested whether (1) chronic fatigue syndrome (CFS) individuals have a bias in the initial orientation of attention to illness-related information, which is enhanced by rumination. (2) CFS individuals have an illness interpretation bias (IB) in their early automatic processing of ambiguous information. (3) CFS individuals experience a greater degree of mood fluctuation following rumination and distraction inductions.

DESIGN: Thirty-three CFS participants who had received a medical practitioner’s diagnosis of CFS were compared to 33 healthy matched controls on an exogenous cueing task and a lexical decision task.

METHOD: All participants underwent either a rumination or distraction induction. They then completed an exogenous cueing task to assess bias to illness and social threat compared with neutral stimuli, as well as a lexical decision task to assess their interpretation of ambiguous words having illness, social threat, or neutral interpretations.

RESULTS: Reaction time data revealed that CFS individuals did not have an attentional bias (AB) in the initial orientation of attention to illness-related material. Nor was there an IB towards illness in CFS individual’s automatic response to ambiguous information. However, as hypothesized, CFS individuals showed a greater degree of mood fluctuation following the rumination/distraction induction.

CONCLUSION: Rumination and distraction lead to greater mood volatility in CFS individuals than in controls, but not to attentional nor interpretation biases in the early automatic stages of information processing in CFS individuals.

Hypothalamic-pituitary-gonadal axis hormones and cortisol in both menstrual phases of women with chronic fatigue syndrome and effect of depressive mood on these hormones

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) is a disease which defined as medically unexplained, disabling fatigue of 6 months or more duration and often accompanied by several of a long list of physical complaints. We aimed to investigate abnormalities of hypothalamic-pituitary-gonadal (HPG) axis hormones and cortisol concentrations in premenopausal women with CFS and find out effects of depression rate on these hormones.

METHODS: We examined follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone and cortisol concentrations in 43 premenopausal women (mean age: 32.86 +/- 7.11) with CFS and compared matched 35 healthy controls (mean age: 31.14 +/- 6.19). Patients were divided according to menstrual cycle phases (follicular and luteal) and compared with matched phase controls. Depression rate was assessed by Beck Depression Inventory (BDI), and patients with high BDI scores were compared to patients with low BDI scores.

RESULTS: There were no significant differences in FSH, LH, estradiol and progesterone levels in both of menstrual phases of patients versus controls. Cortisol levels were significantly lower in patients compared to controls. There were no significant differences in all hormone levels in patients with high depression scores versus patients with low depression scores.

CONCLUSION: In spite of high depression rate, low cortisol concentration and normal HPG axis hormones of both menstrual phases are detected in premenopausal women with CFS. There is no differentiation between patients with high and low depression rate in all hormone levels. Depression condition of CFS may be different from classical depression and evaluation of HPG and HPA axis should be performed for understanding of pathophysiology of CFS and planning of treatment.

Functional status, neuropsychological functioning, and mood in chronic fatigue syndrome (CFS): relationship to psychiatric disorder

Abstract:

Individuals with chronic fatigue syndrome (CFS) face chronic physical debilitation, reduced neuropsychological functioning, and changes in emotional well-being that significantly detract from quality of life. The role of psychiatric disturbance in reducing quality of life in CFS remains unclear. In the current investigation, the role of psychiatric status in reducing health-related quality of life in CFS was examined.

Four subject groups were compared on measures of functional well-being, mood, and neuropsychological status: individuals with CFS and no history of psychiatric illness, individuals who had current symptoms of psychiatric illness that began after their CFS diagnosis, individuals who had current symptoms of psychiatric illness that began before their CFS diagnosis, and a healthy sedentary control group.

Overall, it was found that individuals with CFS suffer from profound physical impairment. Concurrent psychiatric illness, however, did not adversely affect physical functional capacity. Physical functional capacity was not worse in individuals with a concurrent psychiatric illness. As expected, concurrent psychiatric illness was found to reduce emotional well-being. Moreover, individuals with a psychiatric illness that predated the onset of CFS suffered the greatest emotional distress. Thus, an individual’s psychiatric history should be considered when attempting to understand the factors maintaining disability in CFS.

Longitudinal assessment of neuropsychological functioning, psychiatric status, functional disability and employment status in chronic fatigue syndrome

Abstract:

The longitudinal course of subjective and objective neuropsychological functioning, psychological functioning, disability level, and employment status in chronic fatigue syndrome (CFS) was examined. The relations among several key outcomes at follow-up, as well as the baseline characteristics that predict change (e.g., improvement), were also evaluated.

The study sample consisted of 35 individuals who met the 1988 and 1994 CFS case definition criteria of the Centers for Disease Control (CDC) at intake. Participants were evaluated a mean of 41.9 (SEM = 1.7) months following their initial visit (range = 24-63 months).

Results indicated that objective and subjective attention abilities, mood, level of fatigue, and disability improve over time in individuals with CFS. Moreover, improvements in these areas were found to be interrelated at follow-up. Finally, psychiatric status, age, and between-test duration were significant predictors of outcome. Overall, the prognosis for CFS appears to be poor, as the majority of participants remained functionally impaired over time and were unemployed at follow-up, despite the noted improvements.

Illness perceptions and mood in chronic fatigue syndrome

Abstract:

BACKGROUND: Individual beliefs and cognitions may affect adjustment to chronic fatigue syndrome (CFS) and illness perceptions, in particular, have been reported to correlate with both disability and psychological adjustment to CFS in self-diagnosed cases.

OBJECTIVES: The aim of the present study was to examine these relationships in a clinic sample of CFS patients assessed by both a physician and psychiatrist.

METHOD: A sample of 173 patients referred to a multidisciplinary CFS clinic and fulfilling current operational criteria for CFS [Ann Intern Med 121 (1994) 953; J R Soc Med 84 (1991) 118.] were randomly selected from the clinic database and surveyed with the Hospital Anxiety and Depression scale, Fatigue Questionnaire and Illness Perceptions Questionnaire [J Psychosom Res 37 (1993) 147; Psychol Health 11 (1996) 431; Acta Psychiatr Scand 67 (1983) 361.].

RESULTS: A total of 126 patients responded (73% response rate). The illness perception components studied were consequences (of illness), illness identity, causes (of illness), the ability to control/cure the illness and (expected) timeline of the illness. These components accounted for 15%, 28% and 30% of the variance in levels of fatigue, depression and anxiety, respectively. Two of the illness perception components (consequences and illness identity) were stronger predictors of fatigue score than mood scores.

CONCLUSIONS: These findings confirmed in a clinical sample that illness perceptions are associated with variation in both disability and psychological adjustment in CFS. Illness perceptions may have an important and long-lasting effect on adaptation to CFS, and it is necessary to have a greater understanding of their role in order to tailor effective interventions for the condition.

Associations between perfectionism, mood, and fatigue in chronic fatigue syndrome: a pilot study

Abstract:

This study investigated possible associations between perfectionistic personality traits, mood, and fatigue in chronic fatigue syndrome (CFS). Forty CFS sufferers referred to tertiary care and 31 control healthy subjects completed the Multidimensional Perfectionism Scale (MPS), Chalder Fatigue Questionnaire, and Hospital Anxiety and Depression (HAD) scale.

Total perfectionism scores did not correlate with fatigue, anxiety, or depression in either group. Other-oriented MPS scores were significantly lower among CFS sufferers (p = .0019), especially women, and correlated negatively with physical fatigue levels overall (R = -0.27, p = .02). Total and socially prescribed MPS scores correlated with age for the CFS group alone (p = .05).

Possible reasons why this study did not confirm a positive association between perfectionism and CFS are discussed. The finding that CFS sufferers set lower standards and have lower expectations for significant others may have implications for rehabilitation and recovery from this disorder.

Natural history of severe chronic fatigue syndrome

Abstract:

OBJECTIVE: To evaluate the natural history of chronic fatigue syndrome (CFS) in a severely ill group of patients at three points in time.

DESIGN: Patients were enrolled from April 1992 to February 1994 and were evaluated three times. Time 1 (at enrollment): history, physical evaluation, and psychiatric evaluation; Time 2 (median = 1.6yrs after initial evaluation): postal questionnaire to assess current condition; Time 3 (median = 1.8 yrs after Time 2): medical and psychiatric evaluations.

SETTING: The New Jersey CFS Cooperative Research Center, an ambulatory setting.

PATIENTS: Twenty-three patients fulfilled the 1988 case definition for CFS and had symptom complaints that were substantial or worse in severity. All patients were ill less than 4.5 years; and none had a DSM-III-R psychiatric disorder in the 5 years before illness onset; none had substance abuse in the 10 years before enrollment.

MAIN OUTCOME MEASURES: Severity of CFS symptoms was assessed by self-report questionnaires, laboratory tests, and medical examination. Psychological status was assessed using the Q-D15 and the Centers for Epidemiological Study-Depression Scale. At each time of evaluation, patients were categorized as severe, slightly improved, improved, and recovered.

RESULTS: Over the 4 years of the study, 13 patients remained severely ill, 9 improved but still fulfilled the 1994 case definition for CFS, and 1 recovered. Illness duration, mode of onset, psychiatric status or depressed mood at intake, or chemical sensitivity did not predict illness outcome. One patient was diagnosed with an alternate illness, but it probably did not explain her CFS symptoms. Mood improved for those patients whose illness lessened.

CONCLUSIONS: The prognosis for recovery was extremely poor for the severely ill subset of CFS patients. The majority showed no symptom improvement and only 4% of the patients recovered. Illness severity between Times 2 and 3 remained stable.

The psychotherapeutic effects of estrogens

Abstract:

The effect of estrogens on the central nervous system, particularly mood and behavior, remains a controversial area which needs clarification, not just for understanding of depression in women but to ensure that such commonplace problems in women have efficient and appropriate therapy.

There is now good evidence that estrogens are rapidly effective in the treatment of depression in many women but this information has not found its way through to those health care personnel, psychiatrists and psychologists who are principally involved in the treatment of depression. There is also strong evidence for the benefits of estrogens on cognitive functioning, not only in preventing the onset of dementia but also in improving the symptoms in the established condition.

Recent work has also suggested a benefit for estrogens on mood in women diagnosed as suffering from chronic fatigue syndrome. This article reviews the effect of endogenous estrogen on the female central nervous system and the ever increasing evidence for the diverse psychotherapeutic effects of exogenous estrogens.

An assessment of cognitive function and mood in chronic fatigue syndrome

Abstract:

Data were gathered regarding the associates of chronic fatigue syndrome (CFS) with: (1) speed of cognitive processing, (2) motor speed, (3) ability to sustain attention, and (4) mood. Patients were given a brief neuropsychological test battery before and after double-blind treatment with terfenadine or placebo and completed a daily mood rating scale (Positive and Negative Affect Schedule) during the study.

CFS patients exhibited slower cognitive processing and motor speed and lower positive affect, as compared to data reported from previous studies of healthy subjects and other patient groups; however, CFS patients did not exhibit deficits in sustained attention in comparison to other groups.

The CFS patients’ ability to attend to verbal versus figural stimuli and mood ratings were different from those reported in studies of patients with depression. Because of methodological limitations, these findings are preliminary, but they encourage further assessment of cognitive dysfunction and mood in CFS.

Behavioural problems associated with the chronic fatigue syndrome

Abstract:

Disturbances of memory, concentration and motor function are often reported by patients with the chronic fatigue syndrome (CFS). The present study objectively evaluated these behavioural problems using a computerized test battery measuring memory, attention and motor skills.

Fifty-seven CFS patients were compared with 19 matched controls and all subjects completed the performance test battery and filled in questionnaires measuring psychopathology and mood. The patients reported significantly higher levels of depression, anxiety, physical symptoms and cognitive failures than the controls. Similarly, they reported more negative affect at the time of testing.

The patients were slower on psychomotor tasks, showed increased visual sensitivity and impaired attention. Digit span and free recall were not impaired but retrieval from semantic memory and logical reasoning were slower. None of the performance differences between patients and controls could be attributed to differences in psychopathology. These results agree with recent findings from other laboratories, and it is now time to consider the nature of the neurological dysfunction underlying these effects.
