The purpose of this investigation is to determine if the high prevalence rates of major depression, panic disorder, and agoraphobia found in tertiary-care studies of irritable bowel syndrome and medically unexplained gastrointestinal symptoms are also found in the general population. Structured psychiatric interviews on 18,571 subjects from the NIMH Epidemiologic Catchment Area (ECA) Study were reviewed for prevalence of gastrointestinal distress symptoms and selected psychiatric disorders. Medically unexplained gastrointestinal symptoms had a high prevalence in the general population (6-25%). When compared with those reporting no gastrointestinal symptoms, subjects who report at least one of these symptoms were significantly more likely to have also experienced lifetime episodes of major depression (7.5% vs 2.9%), panic disorder (2.5% vs 0.7%), or agoraphobia (10.0% vs 3.6%). Subjects with two gastrointestinal symptoms had even higher lifetime rates of depression (13.4%), panic (5.2%), or agoraphobia (17.8%). Lifetime rates of affective and anxiety disorders in the general population are higher in subjects with gastrointestinal symptoms compared with subjects without gastrointestinal symptoms. An even higher prevalence of affective and anxiety disorders is found in patients with medically unexplained gastrointestinal symptoms in tertiary-care clinics. Future studies are needed in primary-care populations where prevalence rates of psychiatric illness are probably intermediate between those of the general population and tertiary care.

Although spousal bereavement in late life is common and frequently leads to major depression, the boundary between bereavement without a depressive syndrome and bereavement-related depression has been insufficiently studied from a physiological perspective. Because other forms of depression are associated with physiological changes, including sleep, we have attempted to clarify the relationship of bereavement and bereavement-related depression by investigating electroencephalographic (EEG) sleep in 31 elderly volunteers with recent spousal bereavement, stratified by the presence (n = 15) or the absence (n = 16) of major depression (Research Diagnostic Criteria). Entry into the study was limited to volunteers without a personal history of psychiatric disorder. As hypothesized, bereaved subjects with major depression had significantly lower sleep efficiency, more early morning awakening, shorter rapid eye movement (REM) latency, greater REM sleep percent, and lower rates of delta wave generation in the first nonREM (NREM) period, compared with bereaved subjects without depression. Furthermore, the sleep of bereaved subjects with single-episode major depression resembled that of elderly patients with recurrent unipolar major depression (n = 15) on measures noted above. Sleep in bereavement without depression was similar to that of 15 healthy control subjects (neither bereaved nor depressed). These findings suggest that the current DSM-III-R concept of uncomplicated bereavement is not confirmed, as the sleep patterns of subjects who develop a depressive syndrome in the context of bereavement, many of whom might be considered to have "uncomplicated bereavement" by DSM-III-R standards, are identical to sleep patterns found in major depressive episodes. To our knowledge, this is the first study of EEG sleep in spousal bereavement with and without major depression.

The relatives, controls, and spouses of affectively ill probands underwent diagnostic examinations on two occasions, 6 years apart. Of 965 subjects who had never been mentally ill when first examined, 11.8% had development of at least one episode of major depression as defined by the Research Diagnostic Criteria during the ensuing 6 years. Subjects younger than 40 years were three times more likely than older subjects to develop depression and women were approximately twice as likely as men to develop depression regardless of age. Marital disruption, a farm setting, and high educational achievement substantially increased the risk of depression among female subjects. Of 214 never-depressed subjects with a history of nonaffective mental disorder, 62 (29.0%) developed major depression. Age and sex were again powerful determinants. The course of prospectively observed secondary depression was more severe than that for primary depression.

The validity of the general neurotic syndrome, a combination of anxiety, depression and dependent personality disorder, was examined in a 2-year study of outpatients with dysthymic, panic and generalized anxiety disorder diagnosed using a structured interview schedule. The general neurotic syndrome, found in a third of the patients, was associated with greater mental disorder and a significantly worse outcome than patients without the syndrome. It did not, however, predict response to treatment. Further analysis revealed that the general neurotic syndrome was a better predictor of short- and long-term outcome than any other variable apart from initial psychopathology score. It is argued that the syndrome may represent a personality diathesis that makes the individual more vulnerable to both anxiety and depressive symptoms.

Obsessive compulsive disorder is now recognized as a common psychiatric disorder. The lifetime prevalence of 2% to 3% found in the United States has also been found in epidemiologic studies in several other countries with diverse cultures. This disorder has previously been underestimated due to a number of factors that include patients' reluctance to spontaneously admit to obsessions and compulsions and the omission of screening questions about obsessive compulsive disorder on routine mental status examinations. Depression and other anxiety disorders frequently co-occur with obsessive compulsive disorder, which may contribute to misdiagnosis. Patients with eating disorders, Gilles de la Tourette's syndrome, and schizophrenia have a greater comorbid risk compared with the general population. Differential diagnosis of obsessive compulsive disorder includes generalized anxiety disorder, panic disorder, phobias, compulsive personality disorder, and hypochondriasis. While many of these syndromes are characterized by intrusive thoughts, few have associated rituals. The complex tics seen in some patients with Tourette's syndrome may be difficult to distinguish from the compulsions seen in obsessive compulsive disorder, and, in fact, there is significant overlap in symptoms between the two disorders. Currently, the impulse control disorders, such as compulsive gambling and the paraphilias, are not considered to be part of obsessive compulsive disorder. Although the phenomenology of obsessive compulsive disorder appears to be quite diverse, with many distinct kinds of obsessions and compulsions, there are three important core features: abnormal risk assessment, pathologic doubt, and incompleteness. These features cut across phenomenological subtypes and may be useful in defining homogeneous subgroups with distinct treatment outcomes.

Historically, affective disorders have been underdiagnosed among minorities, while schizophrenia is often overdiagnosed. Cultural differences in symptomatology, such as increased reports of auditory hallucinations, or language differences reportedly contribute to misdiagnoses in Hispanics. Consequently, we performed a thorough evaluation of Hispanic patients with a history of schizophrenia who remained diagnostic enigmas. Evaluation included the use of a Spanish-speaking interpreter, strict adherence to criteria of the Diagnostic and Statistical Manual of Mental Disorders, third edition (revised), and the dexamethasone suppression test. Five patients met criteria for major depression, and all but one were properly classified using the dexamethasone suppression test. Careful evaluation is needed with appropriate cultural and diagnostics support to avoid missing depression in Hispanics. The dexamethasone suppression test may be a useful adjunct in some difficult-to-diagnose patients.

Psychiatric disorders and behaviour problems were found to be commoner in children and adolescents with inflammatory bowel disease (IBD) than in matched comparison groups with tension headache and diabetes as well as in healthy children. Depression, anxiety and low self-esteem were common. Many children denied their problems. This may be due to the type of illness, its social consequences and the embarrassment experienced by the children. Discrepancies were found between the children's and their mothers' replies. These results are discussed in terms of their implication for paediatric practice.

Integration vs. polarization is an issue which presents in various aspects of psychiatry. Its position within medicine is still insecure, partly because of a one-sided preoccupation at times with psychodynamic or social factors. The same divisive tendencies are evident within psychiatry itself. Biological science can make an essential contribution to psychiatry, as recent research on depression demonstrates. But only by combining pharmacotherapy with psychosocial interventions can optimal treatment results be achieved. Within psychotherapy there is an ever stronger trend towards integration of schools and methods. Research in outcome could not demonstrate any clear superiority of one single method over the other approximately 200 methods now known. Consequences for research and practice are discussed. The relationship of psychiatry with society is rather tense, being largely based on prejudice. This should be understood less as a global criticism than as an attempt of individuals and society at large to cope with the potential threat of mental illness. Psychiatry must take its responsibility towards society seriously, especially with regard to economic and ethical issues, and afford priority in care to those in the urgent need.

In serious mental illness (SMI) even good community care does not usually make a major impact on clinical or social function, but patients and relatives prefer community to hospital care, and it tends to be cheaper. Any gains are lost if the required community services are not resourced, coordinated, and maintained indefinitely. A few SMI patients continue to need asylum under one roof. CPNs see more anxiety/depression than SMI. Their patients come increasingly from GPs, and they tend to work in practices with less need. Their cost-effectiveness is uncertain, although nurse behaviour therapists are cost-effective in anxiety disorders in primary care. Such research is also needed into the work of other mental health professionals. Despite their effectiveness, there is a dearth of behaviour therapists among nurses and psychiatrists. Problem-orientated training is lacking for most professionals with most patients. Behavioural self-treatments have improved phobic disorders and non-severe depression in controlled studies. Gains were as great when self-treatment was guided by a computer or by a manual as by a clinician. Self-help can extend care delivery, with therapists acting as consultants. Computers can also aid clinical audit.
