Family health and characteristics in chronic fatigue syndrome, juvenile rheumatoid arthritis, and emotional disorders of childhood

OBJECTIVE: To compare family health and characteristics in children with chronic fatigue syndrome (CFS), in juvenile rheumatoid arthritis (JRA), and emotional disorders. METHOD: Parents of 28 children and adolescents aged 11 to 18 years with CFS, 30 with JRA, and 27 with emotional disorders (i.e., anxiety and/or depressive disorders) were recruited from specialty clinical settings and completed interviews and questionnaires assessing family health problems, parental mental distress, illness attitudes, and family burden of illness. RESULTS: Parents of children with CFS were significantly more likely than those of children with JRA to report a history of CFS-like illness, high levels of mental distress, and a tendency to experience functional impairment in response to physical symptoms. Families of children with CFS were characterized by significantly greater emotional involvement and reported greater family burden related to the child's illness in comparison with families of children with JRA. CONCLUSIONS: CFS in childhood and adolescence is associated with higher levels of parental CFS-like illness, mental distress, emotional involvement, and family illness burden than those observed in association with JRA, a chronic pediatric physical illness.     

Psychiatric adjustment in adolescents with a history of chronic fatigue syndrome

OBJECTIVE: To ascertain psychiatric adjustment in youngsters with a history of childhood chronic fatigue syndrome (CFS). METHOD: Subjects were 25 children and adolescents with CFS who were seen in tertiary pediatric/psychiatric clinics (mean age 15.6 years, seen a mean of 45.5 months after illness onset; 17 subjects had recovered and 8 were still ill) and 15 healthy matched controls. Youngsters and their parents (usually mothers) were interviewed and completed questionnaires. Instruments used included the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS), the Child Behavior Checklist (CBCL), and the Harter Self-Esteem Questionnaire. RESULTS: At assessment, psychiatric disorders (mainly anxiety and depressive disorders) were present in half the subjects with a history of CFS, a rate significantly higher than in healthy controls. On the CBCL youngsters with a history of CFS had an excess of psychological symptoms and decreased social competence. On the Harter Self-Esteem Questionnaire they reported reduced self-esteem, especially in social competence. Anxiety disorders were significantly more common in recovered subjects than in those with active CFS illness status. CONCLUSIONS: Psychiatric disorders were found to be increased in adolescents with a history of severe CFS; CFS may enhance the risk for or share common predisposing factors with anxiety disorders.     

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

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.     

Childhood experiences of illness and parenting in adults with chronic fatigue syndrome

OBJECTIVE: There are many similarities between chronic fatigue syndrome (CFS), the somatoform disorders and problems otherwise known as "medically unexplained symptoms." There is some evidence to suggest that a combination of inadequate parenting and early illness experience may predispose the individual to develop medically unexplained symptoms in adult life. The aim of this investigation was to compare the contributions of childhood experiences of illness and parenting in adults with CFS with a fracture clinic control group. METHOD: A retrospective case control design was used. Thirty patients with a diagnosis of CFS and 30 patients attending a fracture clinic in an inner London teaching hospital completed questionnaires measuring parental care and protection and were interviewed about childhood experiences of illness. RESULTS: There were no differences in childhood experience of illness in the two groups. However, logistic regression revealed that maternal overprotection and depression were associated with the diagnosis of CFS. CONCLUSION: The findings may represent risk factors for the development of CFS in adult life. It is possible that maternal overprotection in particular is related to the formation of belief systems about avoiding activity that operate to adversely influence behaviour in patients with CFS.     

Attributions and self-esteem in depression and chronic fatigue syndromes

There is considerable overlap in symptomatology between chronic fatigue syndrome (CFS) and affective disorder. We report a comparison of depressive phenomenology and attributional style between a group of CFS subjects seen in a specialized medical setting, which included a high proportion with depression diagnosed by Research Diagnostic Criteria (RDC) and depressed controls seen in a specialized psychiatric setting. Significant symptomatic differences between the depressed CFS group and depressed controls were observed for features such as self-esteem and guilt as well as attribution of illness. All the CFS groups tended to attribute their symptoms to external causes whereas the depressed controls experienced inward attribution. This may have resulted from differences in the severity of mood disorder between the samples, but it is also suggested that an outward style of attribution protects the depressed CFS patients from cognitive changes associated with low mood but at the expense of greater vulnerability towards somatic symptoms such as fatigue.     

Fatigue syndromes: a comparison of chronic "postviral" fatigue with neuromuscular and affective disorders.

Patients (n = 47) presenting to a neurological centre with unexplained chronic "postviral" fatigue (CFS) were studied prospectively. Controls were patients with peripheral fatiguing neuromuscular diseases and inpatients with major depression in a psychiatric hospital. Seventy-two percent of the CFS patients were cases of psychiatric disorder, using criteria that excluded fatigue as a symptom, compared with 36% of the neuromuscular group. There was no difference in subjective complaints of physical fatigue between all groups. Mental fatigue and fatigability was equally common in CFS and affective patients, but only occurred in those neuromuscular patients who were also cases of psychiatric disorder. Overall, the CFS patients more closely resembled the affective than the neuromuscular patients. Attribution of symptoms to physical rather than psychological causes was the principal difference between matched CFS and psychiatric controls. The symptoms of "postviral" fatigue had little ability to discriminate between CFS and affective disorder. The fatigue in CFS appeared central in origin, suggesting it is not primarily a neuromuscular illness. The implications for research and treatment of chronic fatigue are discussed.     

An overview of chronic fatigue syndrome

BACKGROUND: Psychological and immunologic factors both appear to contribute to chronic fatigue syndrome (CFS). By comparing CFS with other disorders in which fatigue is a prominent symptom, the association between fatigue, psychological vulnerability, depression, and immune function may be further defined. Recent data from psychological, neurologic, and immunologic studies that address these issues are reviewed. METHOD: Articles and abstracts covering CFS and related topics of fatigue, depression, and postinfectious syndromes were identified through MEDLINE and Index Medicus (1980-1990) and by bibliographic review of pertinent review articles. RESULTS: The 1988 definition of CFS by the Centers for Disease Control encompasses several conditions in which the major characteristic is severe fatigue associated with constitutional symptoms. Several studies have identified immune dysfunction in CFS patients, but the specificity of these findings remains unclear. Most studies have shown that CFS patients, compared with other patients with chronic medical illness, experience more disabling fatigue. Some investigators have found a higher incidence of concurrent and past psychiatric illness in CFS patients compared with other medical patients, thereby suggesting an underlying psychopathology in CFS. However, other studies have not found a higher than expected incidence of past depression in CFS patients and have further shown that many CFS patients have no identifiable psychopathology. CONCLUSION: CFS appears to be a heterogenous entity. Although there may be a high coincidence of major depression in CFS, a substantial proportion of patients lack any identifiable DSM-III-R psychiatric disorder yet still manifest the syndrome, thereby suggesting it has an autonomous entity. Despite the evolving nature of our current understanding of CFS, a rational diagnostic and therapeutic approach to CFS is possible.     

Differences between patients with chronic fatigue syndrome and with chronic fatigue at an infectious disease clinic in Stockholm,Sweden

Background data were collected from patients presenting with fatigue at the clinic of infectious diseases at Huddinge University Hospital, Stockholm. The main purpose was to look for differences as to demographic and functional status for patients fulfilling criteria for chronic fatigue syndrome (CFS) and chronic fatigue (CF). A cross-sectional questionnaire survey was performed using a variety of instruments. A thorough medical investigation was performed. No difference was found as to social situation, occupation and illness attributions for patients in the two categories. Patients with CFS reported in general a higher degree of 'sickness' with more self-reported somatic symptoms, more self-reported functional impairment and more absence from work. A higher degree of psychiatric comorbidity was observed in CF than in CFS patients. A majority of CFS patients (80%) had an acute infectious onset compared to 43% in the CF group. Presently used criteria might, according to findings presented here, define two different patient categories in a population characterized by severe, prolonged fatigue. Because CFS patients (compared to patients with CF) have more somatic symptoms, more often report an infectious, sudden onset and have less psychiatric comorbidity, and CF patients seem to have more of an emotional, burn-out-like component one could speculate about the existence of different pathogenetic backgrounds behind the two diagnoses.     

The relationship between fatigue and psychiatric disorders: Evidence for the concept of neurasthenia

Objective

Fatigue and psychiatric disorders frequently occur comorbidly and share similar phenomenological features. There has been debate as to whether chronic fatigue, or neurasthenia, should be considered an independent syndrome distinct from psychiatric disorders. We aimed to establish whether persistent fatigue can occur independently from psychiatric disorders and to test the hypothesis that fatigue without comorbid psychiatric symptoms has unique premorbid risk factors. We also aimed to investigate the psychological outcome of any individuals with fatigue.

Methods

The MRC National Survey of Health and Development was used to prospectively follow 5362 participants from birth. A sample of nonfatigued individuals without psychiatric disorder was selected at age 36 and followed until age 43 years (n=2714). At age 43, the presence of new onset fatigue and/or psychiatric disorder was assessed. Information on a number of potential premorbid risk factors was collected between ages 0 and 36 years. Individuals with fatigue but no comorbid psychiatric disorder were then followed up at age 53 years.

Results

At age 43 years, 201 (7.4%) participants reported significant levels of new onset fatigue in the absence of comorbid psychiatric disorder. Despite the absence of case level psychiatric disorder, these individuals did report increased levels of some psychological symptoms. Excessive childhood energy (adjusted OR 2.63, 95% CI 1.55-4.48, P<.001) and being overweight at age 36 (adjusted OR 1.62, 95% CI 1.05-2.49, P=.03) were specific risk factors for fatigue without psychiatric disorder but not fatigue with comorbid psychiatric illness. Neuroticism was a risk factor for fatigue both with and without comorbid psychiatric disorder. Negative life events and a family history of psychiatric illness were only risk factors for fatigue when it occurred comorbidly with psychiatric illness.

Conclusions

A significant proportion of the adult population will suffer from fatigue without comorbid psychiatric disorder. While fatigue and psychiatric disorders share some risk factors, excessive energy in childhood and being overweight as an adult appear to be specific risk factors for fatigue. Our results confirm the significant overlap between fatigue and psychiatric disorders, while also providing evidence for neurasthenia as a separate diagnosis.     

Physicians' diagnoses of psychiatric disorders for people with chronic fatigue syndrome

OBJECTIVE: To examine rates of psychiatric diagnoses given by patients' primary or regular physicians to persons with chronic fatigue syndrome (CFS), persons with psychiatrically explained fatigue, and a control group. Physicians' psychiatric diagnosis and participants' self-reported psychiatric diagnoses were compared to lifetime psychiatric diagnoses as measured by a structured psychiatric interview. METHOD: Participants were recruited as part of a community-based epidemiology study of chronic fatigue syndrome. Medical records of 23 persons with chronic fatigue syndrome, 25 persons with psychiatrically explained chronic fatigue, and 19 persons without chronic fatigue (controls) were examined to determine whether their physician had given a diagnosis of mood, anxiety, somatoform, or psychotic disorder. Lifetime psychiatric status was measured using the Structured Clinical Interview for the DSM-IV (SCID). Participants' self reports of specific psychiatric disorders were assessed as part of a detailed medical questionnaire. RESULTS: Physicians' diagnosis of a psychiatric illness when at least one psychiatric disorder was present ranged from 40 percent in the psychiatrically explained group, 50 percent in the control group, and 64.3 percent in the CFS group. Participants in the psychiatrically explained group were more accurate than physicians in reporting the presence of a psychiatric disorder, and in accurately reporting the presence of a mood or anxiety disorder. CONCLUSIONS: The present investigation found underrecognition of psychiatric illness by physicians, with relatively little misdiagnosis of psychiatric illness. Physicians had particular difficulty assessing psychiatric disorder in those patients whose chronic fatigue was fully explained by a psychiatric disorder. Results emphasized the importance of using participant self report as a screening for psychiatric disorder.     

The epidemiology of chronic fatigue, physical illness, and symptoms of common mental disorders: a cross-sectional survey from the second British National Survey of Psychiatric Morbidity

OBJECTIVE: The study aimed to describe the prevalence of chronic fatigue in the general population and to investigate the extent to which its association with physical illness was independent of other symptoms of common mental disorders. METHODS: Data from the second British National Survey of Psychiatric Morbidity (2000) were analyzed. The survey covered people aged 16 to 74 years living in private households. Chronic fatigue (significant reported fatigue lasting 6 months or more) was ascertained using the revised Clinical Interview Schedule. Information on reported physical illness and sociodemographic factors was considered. Psychiatric symptoms were also assessed using the revised Clinical Interview Schedule. RESULTS: The prevalence of chronic fatigue was 15.0%, and this showed a significant association with the number of reported physical illnesses (odds ratio [OR] per reported illness, 1.79; 95% confidence interval, 1.68-1.90). It was higher in midlife, in women, in participants with less skilled occupations, and in those with lower educational attainment. Chronic fatigue was strongly associated with the presence of depressive symptoms (OR, 5.37), anxiety-related symptoms (OR, 4.66), and with sleep complaints (OR, 4.41). After adjustment for all sociodemographic and psychiatric factors, the number of reported physical illnesses was less strongly but still significantly associated with chronic fatigue (OR, 1.51; 1.39-1.63). CONCLUSION: Physical illness is strongly associated with chronic fatigue. Symptoms of common mental disorders are also associated with chronic fatigue, but the association between physical illness and chronic fatigue is evident even after adjusting for psychiatric symptoms. The assessment of physically ill people should include chronic fatigue and psychiatric symptoms.     

Childhood predictors of psychiatric disorders among boys: a prospective community-based follow-up study from age 8 years to early adulthood

OBJECTIVE: To study early childhood predictors for early adulthood psychiatric disorders. METHOD: The sample included 2,712 Finnish boys born in 1981. Information about the 8-year-old boys' problem behavior was obtained from parents, teachers, and children. The 10-15-year follow-up information about psychiatric disorders in early adulthood was based on the national military register between the years 1999 and 2004. RESULTS: According to the military register, 10.4% of men had a psychiatric disorder. All informant sources, parents, teachers, and the children themselves predicted early adulthood psychiatric disorders. Conduct symptoms at age 8 independently predicted substance abuse, antisocial personality, and psychotic disorders in early adulthood. Self-reported depressive symptoms, poor school performance, and living in a nonintact family had an independent predictive association with antisocial personality and depressive disorders. Parent-reported emotional symptoms and self-reported psychosomatic symptoms independently predicted anxiety disorders. About one third of those who had used services at age 8 had a psychiatric disorder in early adulthood. Among service users, conduct and hyperkinetic symptoms predicted psychiatric disorders in early adulthood. CONCLUSIONS: Efforts to prevent early adult psychiatric disturbance already present in childhood are emphasized. Active screening to detect children in need of early interventions in childhood to prevent negative development in early adulthood is justified.     

Temper Loss and Persistent Irritability in Preschoolers: Implications for Diagnosing Disruptive Mood Dysregulation Disorder in Early Childhood

Disruptive Mood Dysregulation Disorder (DMDD) is a new and controversial child psychiatric disorder characterized by persistent irritability and frequent temper loss. Among the controversies surrounding DMDD is whether the age of onset criterion—that DMDD may not be diagnosed before age 6 years—is justified. This study examined DMDD symptoms and associated patterns of psychiatric comorbidity, behavioral, and family functioning in a sample of 139 preschoolers (ages 4–0 to 5–11 years) admitted to an early childhood psychiatric day treatment program. DMDD symptoms were common in this acute clinical sample, with 63 children (45.3 %) presenting with frequent temper outbursts and chronic irritability. As compared to children who did not present with DMDD symptoms, these children demonstrated more aggression and emotional reactivity and lower receptive language skills, with high rates of comorbidity with the disruptive behavior disorders. Findings contribute to an emerging literature on preschool DMDD, with implications for early childhood psychiatric assessment and clinical interventions.     

Psychological correlates of functional status in chronic fatigue syndrome

Background: The present study was designed to test a cognitive model of impairment in chronic fatigue syndrome (CFS) in which disability is a function of severity of fatigue and depressive symptoms, generalized somatic symptom attributions and generalized illness worry. Methods: We compared 45 CFS and 40 multiple sclerosis (MS) outpatients on measures of functional ability, fatigue severity, depressive symptoms, somatic symptom attribution and illness worry. Results: The results confirmed previous findings of lower levels of functional status and greater fatigue among CFS patients compared to a group of patients with MS. Fatigue severity was found to be a significant predictor of physical functioning but not of psychosocial functioning in both groups. In CFS, when level of fatigue was controlled, making more somatic attributions was associated with worse physical functioning, and both illness worry and depressive symptoms were associated with worse psychosocial functioning. Conclusions: Our findings support the role of depression and illness cognitions in disability in CFS sufferers. Different cognitive factors account for physical and psychosocial disability in CFS and MS. The SF-36 may be sensitive to symptom attributions, suggesting caution in its interpretation when used with patients with ill-defined medical conditions.     

Assessment of Childhood Depression

Background:  Depression as a disorder in childhood began to be increasingly recognised in the 1970s. Epidemiologic community and clinic-based studies have characterised the prevalence, clinical course, and complications of this illness throughout childhood and adolescence into adulthood. This paper reviews two instruments for assessing depression in prepubertal children – the Dominic Interactive and The Preschool Age Psychiatric Assessment. Both instruments are useful in screening for psychiatric disorders and reliably identifying the presence of depressive symptoms in young children.     

Parental divorce as a factor in childhoold psychiatric illness

Although hundreds of papers have been written concerning the effects of separation from parents and bereavement in childhood, the problem of divorce as a factor in psychiatric disturbance in children has been relatively ignored. This neglect is undeserved: in the 15 years following 1950, the number of children affected yearly by divorce in this country doubled, until by 1965 it stood at somewhat more than 600,000 per year¹⁴.Much of the recent literature on the subject^8,13,15 has focused on the effects of the divorce per se in the production of childhood symptoms. Relatively little attention has been paid to antecedents of the divorce or to the possibility that parental divorce and childhood psychiatric illness may both be related secondarily to a common background factor. Because other authors^3,18 have noted the association of certain psychiatric disorders with divorce, it is important to examine the parents and other relatives of psychiatrically ill children for mental illness and to attempt to correlate such illness with marital status.     

The relation of sleep difficulties to fatigue, mood and disability in chronic fatigue syndrome

The relationship of sleep complaints to mood, fatigue, disability, and lifestyle was examined in 69 chronic fatigue syndrome (CFS) patients without psychiatric disorder, 58 CFS patients with psychiatric disorder, 38 psychiatric out-patients with chronic depressive disorders, and 45 healthy controls. The groups were matched for age and gender. There were few differences between the prevalence or nature of sleep complaints of CFS patients with or without current DSM-IIIR depression, anxiety or somatization disorder. CFS patients reported significantly more naps and waking by pain, a similar prevalence of difficulties in maintaining sleep, and significantly less difficulty getting off to sleep compared to depressed patients. Sleep continuity complaints preceded fatigue in only 20% of CFS patients, but there was a strong association between relapse and sleep disturbance. Certain types of sleep disorder were associated with increased disability or fatigue in CFS patients. Disrupted sleep appears to complicate the course of CFS. For the most part, sleep complaints are either attributable to the lifestyle of CFS patients or seem inherent to the underlying condition of CFS. They are generally unrelated to depression or anxiety in CFS.     

Early adverse experience and risk for chronic fatigue syndrome: results from a population-based study

CONTEXT: Chronic fatigue syndrome (CFS) is an important public health problem. The causes of CFS are unknown and effective prevention strategies remain elusive. A growing literature suggests that early adverse experience increases the risk for a range of negative health outcomes, including fatiguing illnesses. Identification of developmental risk factors for CFS is critical to inform pathophysiological research and devise targets for primary prevention. OBJECTIVE: To examine the relationship between early adverse experience and risk for CFS in a population-based sample of clinically confirmed CFS cases and nonfatigued control subjects. DESIGN, SETTING, AND PARTICIPANTS: A case-control study of 43 cases with current CFS and 60 nonfatigued controls identified from a general population sample of 56 146 adult residents from Wichita, Kan. MAIN OUTCOME MEASURES: Self-reported childhood trauma (sexual, physical, and emotional abuse and emotional and physical neglect) and psychopathology (depression, anxiety, and posttraumatic stress disorder) by CFS status. RESULTS: The CFS cases reported significantly higher levels of childhood trauma and psychopathology compared with the controls. Exposure to childhood trauma was associated with a 3- to 8-fold increased risk for CFS across different trauma types. There was a graded relationship between the degree of trauma exposure and CFS risk. Childhood trauma was associated with greater CFS symptom severity and with symptoms of depression, anxiety, and posttraumatic stress disorder. The risk for CFS conveyed by childhood trauma increased with the presence of concurrent psychopathology. CONCLUSIONS: This study provides evidence of increased levels of multiple types of childhood trauma in a population-based sample of clinically confirmed CFS cases compared with nonfatigued controls. Our results suggest that childhood trauma is an important risk factor for CFS. This risk was in part associated with altered emotional state. Studies scrutinizing the psychological and neurobiological mechanisms that translate childhood adversity into CFS risk may provide direct targets for the early prevention of CFS.     

Symptomatic presentation and initial treatment for schizophrenia in children and adolescents

Childhood-onset schizophrenia is a rare variant of adult-onset schizophrenia. Patients with early-onset schizophrenia typically have a more chronic course of illness, greater cognitive impairment, increased negative symptoms, and more severe social consequences than patients with adult-onset schizophrenia. Misdiagnosis of childhood-onset schizophrenia is common, but certain clinical features, such as predominant negative symptoms and premorbid developmental abnormalities, can help to differentiate the disorder from other psychiatric disorders in childhood. Treatment regimens that include both pharmacotherapy and psychosocial interventions are needed to comprehensively treat children and adolescents with schizophrenia.     

Cognitive behaviour therapy in chronic fatigue syndrome.

Fifty patients fulfilling operational criteria for the chronic fatigue syndrome (CFS), and who had been ill for a mean of five years, were offered cognitive behaviour therapy in an open trial. Those fulfilling operational criteria for depressive illness were also offered tricyclic antidepressants. The rationale was that a distinction be drawn between factors that precipitate the illness and those that perpetuate it. Among the latter are cognitive factors such as the belief that physical symptoms always imply tissue damage, and behavioural factors such as persistent avoidance of activities associated with an increase in symptoms. Therapy led to substantial improvements in overall disability, fatigue, somatic and psychiatric symptoms. The principal problems encountered were a high refusal rate and difficulties in treating affective disorders. Outcome depended more on the strength of the initial attribution of symptoms to exclusively physical causes, and was not influenced by length of illness. These results suggest that current views on both treatment and prognosis in CFS are unnecessarily pessimistic. It is also suggested that advice currently offered to chronic patients, to avoid physical and mental activity, is counterproductive.
