Hysteria: a case note study

The symptom of functional weakness: a controlled study of 107 patients

Functional weakness describes weakness which is both internally inconsistent and incongruent with any recognizable neurological disease. It may be diagnosed as a manifestation of conversion disorder or dissociative motor disorder. Other names include psychogenic or 'non-organic' paralysis. We aimed to describe the incidence, demographic and clinical characteristics of cases with functional weakness of less than 2 years duration, and to compare these with controls with weakness attributable to neurological disease. Both cases and controls were recruited from consultant neurologists in South East Scotland. Participating patients underwent detailed assessments which included: physical examination, structured psychiatric interview (Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders), measures of symptoms, disability and distress [Short Form (36) Health Survey, Hospital and Anxiety Depression Scale], and assessment of their illness beliefs using an augmented version of the Illness Perception Questionnaire. In total, 107 cases (79% female, mean age 39 years, median duration of illness 9 months) were recruited. This number suggests a minimum annual incidence of 3.9/100 000. Forty-six controls (83% female, median age 39 years, duration 11 months) were also recruited. Compared to controls, cases had similar levels of disability but more physical symptoms, especially pain. They had a higher frequency of psychiatric disorders, especially current major depression (32 versus 7%, P < 0.0001), generalized anxiety disorder (21 versus 2%, P < 0.005), panic disorder (36 versus 13%, P < 0.001) and somatization disorder (27 versus 0%, P < 0001). There was no difference in median self-rated anxiety and depression scores. Paradoxically, they were less likely than controls to agree that stress was a possible cause of their illness (24 versus 56%, P < 0.001). Cases were twice as likely as controls to report that they were not working because of their symptoms (65 versus 33%, P < 0.0005). Functional weakness is a commonly encountered clinical problem. Patients with this symptom are as disabled as patients with weakness of similar duration due to neurological disease. There is a paradox between the frequency of depression and anxiety diagnoses and the patient's willingness to accept these as potentially relevant to their symptoms. We discuss the theoretical and practical implications of these findings for the concept of conversion disorder.

Somatization disorder: a practical review

OBJECTIVE

This paper reviews the present state of knowledge on the etiology, prevalence, diagnosis, and treatment of somatization disorder (SD).

METHOD

A comprehensive review of the literature on SD is described under the above headings.

RESULTS

SD is a common condition that is not well managed by many physicians. Patients with SD get caught between the cracks of the health care system, with expensive consequences. SD is a psychiatric disorder, but patients are reluctant to see and be treated by psychiatrists. They frequently are managed by nonpsychiatric physicians who have limited understanding of the condition. Cognitive-behavioural therapy (CBT) is the most efficacious treatment in SD, although antidepressants and supportive psychotherapy also have a role for some patients.

CONCLUSIONS

A cadre of clinicians with training in the theory and practice of CBT for SD is required. They need to be based both in the community and in tertiary health care centres, where most patients with this condition are located.

"Hysteria" in clinical neurology

Hysteria is an ancient word for a common clinical condition. Although it no longer appears in official diagnostic classifications, "hysteria" is used here as a generic term to cover both "somatoform" and "dissociative" disorders as these are related psychopathological states. This paper reviews the clinical features of four hysterical syndromes known to occur in a neurologist's practice, viz conversion, somatization and pain disorders, and psychogenic amnesia. The presence in the clinical history of a multiplicity of symptoms, prodromal stress, a "model" for the symptom(s), and secondary reinforcement all suggest the diagnosis, and minimise the need for extensive investigations to rule out organic disease. Psychodynamic, behavioral, psychophysiologic and genetic factors have been proffered to explain etiology. Appropriate treatment involves psychotherapeutic, behavioral and pharmacological techniques. A basic requirement is to avoid errors of commission such as multiple specialist referrals and invasive diagnostic and treatment procedures. Hysteria is a remediable condition if identified early and managed appropriately.

Birth Order and health: major issues

Birth Order has been described as a variable with a complex relationship to child and adult outcomes. A review of the medical literature over the past 5 years identified 20 studies that investigated the relationship between Birth Order and a health outcome. Only one of the studies established a relationship between Birth Order and a health outcome: third and fourth-born children have a higher incidence of accidents that result in hospitalization. The other demonstrated relationships are each explained by intervening variables or methodological limitations. Although Birth Order is not a strongly independent explanatory factor in understanding health outcomes, it is an important marker variable. Statistically significant relationships between Birth Order and health outcomes yield insights into the ways a family influences an individual's health.

Psychogenic voice disorders: literature review and case report

This paper explores some of the similarities and differences between hysteria and hypochondriasis and suggests that voice disorders are a prototype of disorders which reflect the intricate interplay of emotional, cognitive and physiological functions. Speech production requires the involvement of various systems of the body, including the central nervous system, respiratory and vocal systems. Voice disorders can take many different forms and can be caused by a variety of factors. A review of the relevant literature is presented along with a clinical case record of a woman with hysterical dysarthria.

Hysteria--a neurologist's view

Hysterical symptoms are defined as complaints that are not fully explained by organic or functional neurological disease. Hysterical symptoms are common in neurological practice, accounting for about 1% of neurological diagnoses. Of those with neurological hysterical symptoms, about 80% will not have the hysterical personality, and about 80% will not have Briquet's hysteria. Some 60% will have a physical disease and perhaps as many as 50% will have recognizable psychiatric illness, particularly depression. Others may have unrecognized physical or psychiatric illness. Many hysterical symptoms may be understood in terms of abnormal illness behaviour.
