Somatization: a spectrum of severity

OBJECTIVE: The DSM-III-R diagnosis of somatization disorder requires that a patient have a specific number of medically unexplained somatic symptoms. This number of symptoms was developed by committee consensus, and it is not clear whether patients with this specific number of symptoms can be differentiated from patients with lower but still substantial numbers of somatic symptoms. METHOD: Fifty-one percent of 767 high utilizers of two primary care clinics were identified as distressed by an elevated SCL anxiety, depression, or somatization scale score or by their primary care physician. The Diagnostic Interview Schedule (DIS) was completed on 119 distressed high utilizers who were randomly assigned to an intervention group in a controlled trial of psychiatric consultation. The 119 distressed high utilizers were separated into four categories according to the number of unexplained somatic symptoms found on the DIS and were compared on demographic, psychiatric distress, disability, medical, and health utilization variables. RESULTS: The data suggest that many clinical and behavioral features of somatization are significantly more common in patients with four to 12 medically unexplained somatic symptoms rather than changing dramatically at the diagnostic threshold for somatization disorder. The data also showed that patients who meet the DSM-III-R criteria for somatization disorder are severely ill and have a high burden of psychiatric illness and disability. CONCLUSIONS: The results suggest that the DSM-IV somatoform disorders section should include somatization disorder, an abridged definition of somatization disorder often associated with anxiety and depression, as well as a type of somatization associated with an adjustment disorder.     

Clinical features associated with medically unexplained stroke-like symptoms presenting to an acute stroke unit

In many areas of secondary care, symptoms unexplained by disease account for around one-third of all patients seen. We sought to investigate patients presenting with medically unexplained stroke-like symptoms to identify distinguishing features which may help to identify a non-organic aetiology. Patients given a discharge diagnosis of medically unexplained stroke-like symptoms over the preceding 11 years were identified retrospectively from a prospectively completed stroke unit database. Age- and sex-matched controls with ischaemic or haemorrhagic stroke or transient ischaemic attack were also identified. Clinical features on presentation, ischaemic risk factors, alcohol history, marital status and history of depression or anxiety were examined. Previous or subsequent admissions with medically unexplained syndromes were also examined via record linkage with hospital discharge records. A medically unexplained syndrome was assumed to be present if an International Classification of Diseases 9 discharge code for one or more of the thirteen conditions forming recognized functional syndromes was given. Logistic regression was applied to determine predictors of non-organicity. One hundred and five patients and controls, 1.6% of all stroke unit admissions were identified, 62% (65 patients) were females. Mean age was 50.3 +/- 14.9. Compared with age- and sex-matched controls patients with medically unexplained stroke-like symptoms were significantly more probable to have a headache at presentation (47% vs. 26%, P = 0.0004), have a diagnosis of one or more additional medically unexplained syndromes (24% vs. 11%, P = 0.007) but significantly less probable to present with symptoms of vertebrobasilar dysfunction (32% vs. 61%, P < 0.0001). A history of anxiety or depression, as recorded in the notes, was not found to be associated with a medically unexplained presentation. Medically unexplained stroke-like presentations are common (1.6% of all stroke presentations), they are most strongly predicted by the presence of other functional somatic syndromes, headache and the absence of symptoms of vertebrobasilar dysfunction.     

Social factors associated with chronic depression among a population-based sample of women in rural Pakistan

Abstract Objective Previous studies have reported a high prevalence of depression in women in Pakistan. This paper investigates whether risk factors for chronic depression established in studies performed in Western countries can explain this high prevalence. Method A two–phase survey using the self–rating questionnaire (SRQ) for common mental disorders and the Psychiatric Assessment Schedule was performed on a general population sample in rural Pakistan. Demographic data and results of the Life Events and Difficulties Schedule were analysed in relation to SRQ score and psychiatric disorder. Results A total of 145 women were screened. High SRQ score was associated with low educational status, not having a confidant, having four or more children, being older, not being married and living in a house with more than three people per room. Regression analysis demonstrated that the first three of these independently contributed to SRQ score. In the interviewed sample (74 women), only educational level independently contributed to the presence of depression. In addition, the least educated group experienced the greatest number of marked difficulties: 67% of them had experienced both marked housing and financial difficulties compared to 28% and 25% of the other educational groups (p = 0.005). Experiencing both housing and financial difficulties was a significant risk factor for depression in women with secondary education, but not for those without secondary education. Conclusions This study suggests that high levels of social adversity and low levels of education are strongly associated with depression in women in Pakistan. The other vulnerability factors found in the West (such as lack of a confidant, the presence of three or more young children at home, or loss of mother during childhood) may be of lesser importance in this population.     

What do medical outpatients attending a neurology clinic think about antidepressants?

OBJECTIVE: To determine how medical outpatients attending a neurology clinic view antidepressant medication and whether those who present with medically unexplained symptoms have different views than those whose symptoms are explained by neurological disease. METHODS: A total of 89 consecutive outpatients attending a medical neurology clinic were interviewed. RESULTS: Those who believed that antidepressants were addictive comprised 74% and those who thought that they could cause physical harm comprised 47%. Only 49% were aware that antidepressants could be used to treat symptoms other than depression. The views of patients whose symptoms were rated by the doctor as being 'not at all' only 'somewhat' unexplained by neurological disease (37% of the total) were neither substantially nor statistically different those whose symptoms were rated as 'largely' or 'completely' explained by neurological disease. CONCLUSION: The majority of medical patients attending a neurology clinic, and not just those with medically unexplained symptoms, have largely negative beliefs about antidepressant drugs. The implications for patient adherence to these agents and for medical practice are discussed.     

Patients who strive to be ill: factitious disorder with physical symptoms

OBJECTIVE: Factitious disorder with physical symptoms characterizes patients who strive to appear medically ill and assume the sick role. Clinical suspicion is highest for female health care workers in the fourth decade of life. This study was designed to analyze the diagnosis of factitious disorder, the demographics of affected patients, and intervention and treatment. METHOD: Retrospective examination was of 93 patients diagnosed during 21 years. Two raters agreed on subject eligibility on the basis of DSM-IV criteria and absence of a somatoform disorder and a plausible medical explanation. RESULTS: The group included 67 women (72.0%); mean age was 30.7 years (SD=8.0) for women and 40.0 years (SD=13.3) for men. Mean age at onset was 25.0 years (SD=7.4). Health care training or jobs were more common for women (65.7%) than men (11.5%). Most often, inexplicable laboratory results established the diagnosis. Eighty had psychiatric consultations; 71 were confronted about their role in the illness. Only 16 acknowledged factitious behavior. Follow-up data were available for only 28 patients (30.1%); maximum duration of follow-up was 156 months. Two patients were known to have died. Few patients pursued psychiatric treatment. Eighteen left the hospital against medical advice. CONCLUSIONS: Factitious disorder affects men and women with different demographic profiles. Diagnosis must be based on careful examination of behavior, motivation, and medical history and not on a stereotype. Laboratory data and outside medical records help identify suspicious circumstances and inconsistencies. Confrontation does not appear to lead to patient acknowledgment and should not be considered necessary for management.     

Medically unexplained cutaneous sensory symptoms may represent somatoform dissociation: an empirical study

OBJECTIVE: We examined the relation between medically unexplained cutaneous symptoms and dissociation [measured by the Dissociative Experiences Scale, or DES; Bernstein EM, Putnam FW. Development, reliability, and validity of a dissociation scale. J Nerv Ment Dis 1986;174:727-35] among participants with no history of primary dermatologic disorders. METHODS: Three hundred sixty consenting participants (44 psychiatric outpatients and 316 nonclinical participants from the community at large) rated the severity of nine medically unexplained cutaneous symptoms (sum of all ratings comprised the Cutaneous9 variable) and completed the DES. RESULTS: The Cutaneous9 variable correlated significantly (Pearson r=.56, P<.001) with DES scores. Stepwise multiple regression analysis using the nine cutaneous symptoms as independent variables revealed that Pain, Itching, and Numbness were the best predictors of the DES scores (adjusted R2=.34, P<.001). CONCLUSION: Our findings have empirically shown that itching, like pain and numbness, may be a symptom of somatoform dissociation. Second, even milder degrees of dissociation in the nonclinical range may play a role in the genesis of unexplained cutaneous sensory symptoms.     

Childhood adversity and frequent medical consultations

We assessed possible psychological mediators of the relationship between childhood adversity and frequent medical consultations among new outpatients at neurology, cardiology, and gastroenterology clinics. We assessed whether these differed in patients with and without organic disease that explained their symptoms. At first clinic visit we recorded Hospital Anxiety and Depression scale (HADS--anxiety and depression subscale scores), Illness Perception Questionnaire (IPQ--four subscales: consequences, cure, identity, timeline), Health Anxiety Questionnaire (total score), and Symptom Amplification Scale (total score). Subjects were divided into two groups according to whether they had experienced any type of childhood adversity using the Childhood Experience of Care and Abuse Schedule. Outcome was the (log) number of medical consultations for 12 months before and 6 months after the index clinic visits. Multiple regression analysis was used to determine mediators; this was performed separately for patients with symptoms explained and not explained by organic disease. One-hundred and twenty-nine patients (61% response) were interviewed. Fifty-two (40.3%) had experienced childhood adversity; they made a median of 16 doctor visits compared with 10 for those without adversity (adjusted P=.026). IPQ identity score (number of symptoms attributed to the illness) and HAD depression scores were significantly associated with both childhood adversity and number of medical consultations and these variables acted as mediators between childhood adversity and frequency of consultation in the multiple regression analyses. This association was limited to patients with medically unexplained symptoms and was mediated by IPQ Identity Score (number of symptoms attributed to the patient's illness) and HAD depression score. Sexual abuse and overt neglect were the adversities most closely associated with frequent consultations. In patients with medically unexplained symptoms the association between childhood adversity and frequent medical consultations is mediated by the number of bodily symptoms attributed to the illness. Psychological treatments should be targeted at these patients with a view to reducing their frequent doctor visits.     

Medically unexplained presentations and quality of life: a study of a predominantly South Asian primary care population in England

Primary care subjects from a predominantly South Asian inner-city setting in Manchester, UK, were studied. We aimed to determine whether medically unexplained symptoms (MUS) are associated with worse health-related quality of life than medically explained symptoms (MES), after controlling for differences in sociodemographic variables, number of somatic symptoms, and levels of anxiety and depression. One hundred nineteen subjects attending general practice completed questionnaires to assess somatic symptoms, anxiety, depression, and quality of life. Doctors' records were later studied to ascertain whether the presentation was medically explained. Thirty-nine subjects (33%) had medically unexplained presentations. Compared to patients with MES, those with MUS had significantly more somatic symptoms (6.9 vs. 4.3, P<.001), higher levels of anxiety (Hospital anxiety and depression scale -- anxiety score) (9.8 vs. 6.7, P=.004), depression (Hospital anxiety and depression scale -- depression) (6.8 vs. 4.5, P=.005), and poorer health-related quality of life (EuroQol standardized score 54.6 vs. 73.3, P=.001). On multiple regression analysis, anxiety, depression, and somatic symptom scores independently (P<.01) predicted quality of life, after controlling for demographic factors. Whether the presentation was medically unexplained or not did not contribute to the regression model (P=.85). Our findings suggest that it is the number of somatic symptoms and the associated anxiety/depression that account for greater impairment in people's health-related quality of life, and not whether they have a medical explanation for their symptoms.     

Recognition of medically unexplained symptoms--do doctors agree?

The aim of this study was to investigate the interrater reliability of the recognition of medically unexplained symptoms by medical investigators. The casenotes of 56 consecutive secondary care out-patient attenders were examined by three medical investigators. The investigators determined whether the presenting symptoms were medically unexplained (not, probable, or definite) and the results were tested for interrater reliability. The combined kappa for the three investigators was 0.76, indicating substantial agreement. This suggests that casenote examination is a reliable method of determining whether a symptom is medically unexplained.     

Psychiatric illness and irritable bowel syndrome: a comparison with inflammatory bowel disease

Structured psychiatric interviews and psychological self-report measures were administered to 28 patients with irritable bowel syndrome and 19 patients with inflammatory bowel disease. Significantly more of the patients with irritable bowel syndrome had lifetime diagnoses of major depression, somatization disorder, generalized anxiety disorder, panic disorder, and phobic disorder. They had significantly more medically unexplained somatic symptoms, and most had suffered from psychiatric disorders, particularly anxiety disorders, before the onset of their irritable bowel symptoms.

ADHD in adult psychiatry. Minimum rates and clinical presentation in general psychiatry outpatients

The objective of the study was to determine the prevalence and comorbidity of persisting attention-deficit hyperactivity disorder (ADHD) in adult psychiatric outpatients. Consecutive patients, first visits excluded, at a general psychiatric outpatient clinic were offered a screening for childhood ADHD with the Wender Utah Rating Scale (WURS). One hundred and forty-one patients out of 398 (35%) completed and returned the scale. Patients above or near cut-off for ADHD (n=57) were offered an extensive clinical evaluation with psychiatric as well as neuropsychological examination. The attrition was analysed regarding age, sex and clinical diagnoses. Out of the screened sample, 40% had scores indicating possible childhood ADHD. These 57 patients were invited to the clinical part of the study, but 10 declined assessment, leaving 47 (37 women and 10 men) who were actually examined. Thirty of these (21 women and nine men) met diagnostic criteria for ADHD at the time of examination. Among the patients with ADHD, affective disorders were the most common psychiatric diagnoses. The rate of alcohol and/or substance abuse, as noted in the medical records, was also high in the ADHD group. In the WURS-screened group, 22% (30 patients assessed as part of this study and one person with ADHD previously clinically diagnosed) were shown to have persisting ADHD. Therefore, it is clearly relevant for psychiatrists working in general adult psychiatry to have ADHD in mind as a diagnostic option, either as the patient's main problem or as a functional impairment predisposing for other psychiatric disorders.     

Gender differences in the phenomenology of bipolar disorder

OBJECTIVES: To investigate gender differences in the phenomenology of episodes in bipolar disorder as according to ICD-10. METHODS: All patients who got a diagnosis of a manic episode/bipolar disorder in a period from 1994 to 2002 at the first outpatient treatment ever or at the first discharge from psychiatric hospitalization ever in Denmark were identified in a nationwide register. RESULTS: Totally, 682 outpatients and 1037 inpatients got a diagnosis of a manic episode/bipolar disorder at the first contact ever. Significantly more women were treated as outpatients than as inpatients. Women were treated for longer periods as inpatients but not as outpatients. In both settings, the prevalence of depressive versus manic/mixed episodes was similar for men and women and the severity of manic episodes (hypomanic /manic without psychosis/manic with psychosis) and the severity of depressive episodes (mild/moderate/severe without psychosis/severe with psychosis) did not differ between genders. The prevalence of psychotic symptoms at first contact was the same for both genders. Among patients treated in outpatient settings more men than women presented with comorbid substance abuse and among patients treated during hospitalization more women than men presented with mixed episodes. CONCLUSIONS: Besides differences in the prevalence of mixed episodes and comorbid substance abuse few gender differences are found among patients presenting with a manic episode/bipolar disorder at first contact in psychiatric inpatient or outpatient hospital settings.

An international study comparing the effect of medically explained and unexplained somatic symptoms on psychosocial outcome

OBJECTIVE: Cross-sectional studies show an association between somatic symptoms and psychiatric morbidity in primary care. However, medically explained and unexplained symptoms have been considered separately as distinct and unrelated. In addition, data on outcome in primary care are equivocal. We compare the effect of both constructs (medically explained and unexplained symptoms) on psychiatric morbidity and disability (social and physical) at 1 year follow-up. METHOD: Of 5447 patients presenting for primary care in 14 countries, 3201 participants were followed up (72% compliance). We measured physical, psychiatric, and social status using standardised instruments. RESULTS: Patients with five or more somatic symptoms had increased psychosocial morbidity and physical disability at follow-up, even after controlling for confounders such as sociodemographics and recognition or treatment by general practitioners. There was little difference in outcome between medically explained and unexplained symptoms. CONCLUSIONS: Somatic symptoms-irrespective of aetiology-are associated with adverse psychosocial and functional outcome in diverse cultures.     

Psychiatric patients' vulnerability in the wake of the September 11th terrorist attacks

The September 11, 2001 (9/11) terrorist attacks led to speculation about the vulnerability of psychiatric patients to psychological distress following such events. This study examined the impact of national terrorist attacks on psychiatric and medical outpatients living approximately 150 to 200 miles from the attack sites (N = 308). Two to 3 weeks following 9/11, patients were given questionnaires assessing background information, healthcare service utilization, and posttraumatic stress disorder (PTSD) symptoms. Psychiatric patients (33%) were significantly more likely than medical patients (13%) to report distressing symptoms meeting criteria for PTSD (except for the duration criterion) despite no differences in learning about the attacks or personal involvement with the victims. Patients meeting PTSD criteria were more likely to schedule an appointment to speak with their physician about their reactions. Psychiatric patients not directly impacted by the 9/11 terrorist attacks are at increased risk for experiencing distressing symptoms following national terrorist attacks.     

Physical symptom disorder: a simpler diagnostic category for somatization-spectrum conditions

OBJECTIVE: To propose a simpler, more empiric, and patient-centered category for classifying physical symptoms that are "etiologically neutral," that is, not reliant on the assumption that symptoms that is poorly explained from a medical standpoint must de facto be psychological in origin. METHODS: Theoretical analysis, narrative review, and proposal. RESULTS: Studies have revealed several limitations in the current classification of somatoform disorders, including the poor reliability of lifetime symptom recall, the difficulty in adjudicating physical versus psychological explanations, and the stigma in assigning patients with medically unexplained symptoms to an Axis I psychiatric disorder. Physical symptom disorder (PSD) is proposed as a diagnostic category that would reside on Axis III (rather than Axis I) and replace somatization disorder, undifferentiated somatoform disorder, and pain disorder. PSD would consist of one or more physical symptoms currently present, not fully explainable by another medical or psychiatric disorder (with the exception of functional somatic syndromes), causing functional impairment. Duration must be at least 6 months, and severity could be graded as mild, moderate, or severe using a 15-symptom checklist (PHQ-15). Finally, the type of symptoms or symptom syndromes present in the patient could be specified. CONCLUSIONS: PSD should be considered as a simpler and more inclusive diagnosis to replace several somatoform diagnoses currently in use.     

The Association of Irritable Bowel Syndrome and Somatization Disorder

Background and objective: Irritable bowel syndrome (IBS) and somatization disorder (SD) are defined by nonobjective symptoms that overlap considerably. Psychiatric symptoms associated with IBS may originate from SD in IBS patients. Previous studies of IBS have not considered SD separately from IBS. Methods: This study explored psychiatric symptoms and illness behavior in IBS in relation to SD. A total of 50 outpatients with IBS or ulcerative colitis (UC) were evaluated with the Diagnostic Interview Schedule and Illness Behavior Questionnaire. Results: Definite or probable SD was diagnosed in no UC patients and in 42% of IBS patients (confirmed in 25% and lacking one symptom in another 17%). IBS patients with probable or definite SD, but not those without SD, reported more psychiatric symptoms and abnormal illness behaviors than did UC patients. SD accounted for the association of psychiatric symptoms with IBS. Conclusions: In this university-based office setting, the association of psychiatric features with IBS appears heterogeneous predicated on whether SD is present. Future studies of functional bowel diseases should distinguish between patients with and without SD to clarify its relationship to these disorders. Clinicians should consider whether patients with functional disorders have SD, a diagnosis that indicates specific clinical management strategies.     

Does somatization disorder occur in men? Clinical characteristics of women and men with multiple unexplained somatic symptoms

Somatization disorder is thought to be rare or nonexistent in men. We examined this hypothesis by assessing gender differences in DSM-III-R diagnostic status, demographic and clinical characteristics, functional limitations, self-reported health status, and psychiatric comorbidity in 30 men and 117 women who were referred for multiple unexplained somatic complaints. Twelve men and 68 women met DSM-III-R criteria for somatization disorder. Among those meeting criteria, there were few differences on any of the dimensions that were assessed. Different referral sources for women and men suggested differences in physicians' perceptions of somatic symptoms in men and women. We concluded that somatization disorder exists in men, and that women and men with somatization disorder show similar clinical characteristics.     

Patients with medically unexplained symptoms: DSM-III diagnoses and demographic characteristics

This study reports DSM-III diagnoses and demographic characteristics of 100 patients consecutively referred to a university hospital consultation-liaison service for evaluation of medically unexplained symptoms suggesting physical disorders. Thirty-seven percent of patients received diagnoses of somatoform, dissociative, or factitious disorders, and 14% were felt to have psychologic factors affecting physical conditions. Although black and male patients were less often referred for medically unexplained symptoms, once referred they were more likely than white and female patients to receive diagnoses of somatoform, dissociative, or factitious disorders. Among patients with somatoform disorders, those with conversion disorder and somatization disorder tended to be young women, whereas those with psychogenic pain disorder were older and equally likely to be male or female.
