Mental health services are of interest not only because of the large burden they impose, but also because they have been subject to more change than virtually any other type of health service over the past four decades. Although both the US and UK have taken to ‘deinstitutionalisation’ with enthusiasm, the US has so far proceeded somewhat further down that road than the UK. While both countries face similar problems, the NHS and Community Care Act 1990 may now lead to considerable further changes in the UK.

As part of its concern with the environmental causes of disease, medical research tries to comprehend the nature of social processes and their implications for human health: an endeavour calling for sociological concepts and methods (Susser et al, 1985). Medical needs are mirrored within sociology, which has never been confined to study of the workings of society, but has always concerned itself also with their impact on individuals and on public health. The importance of cooperation between the two disciplines is thus indisputable. Nevertheless, interprofessional relationships have never been easy, and Pflanz's dictum, that “the history of the relationship between sociology and medicine is … mainly a history of unsuccessful encounters” (Pflanz, 1976), remains substantially true today. The difficulties have been ascribed to interdisciplinary tensions of the kind that arise when a relatively young academic profession seeks to assert its autonomy in a relationship with an older-established and more powerful one. Martin (1976), stressing the dangers that can result from mutually false expectations, invoked the analogy of a marriage in which:

An assessment schedule was used to determine the nature of insight in 91 mixed psychotic patients, and to examine its distribution and associations. While all the components of the schedule intercorrelated significantly, scores for compliance were only weakly related to those for ability to label psychotic phenomena as abnormal. Compliance and illness recognition were related to IQ. Total insight score was inversely correlated, moderately, with a global measure of psychopathology derived from the PSE, and was less in patients involuntarily committed. Age, sex, diagnosis, and the number of previous hospital admissions had little effect. The results support the notion that insight is not a unitary concept.

Studies which have examined the perception of emotion by schizophrenic patients have produced conflicting results, an outcome which may, in part, be due to difficulties in presenting a realistic portrayal of emotion. This study exposed 32 schizophrenic patients in remission and ten controls to five videotaped scenes of emotional situations played by actors. The schizophrenic patients were divided into three groups, namely those living with high-EE relatives, those living with low-EE relatives and those living alone, in order to test the hypothesis that patients in a high-EE environment are less able to identify emotionally charged situations. Measures of electrodermal activity and self-ratings of tension were recorded concomitantly. The schizophrenic patients in all groups were as adept at identifying emotions as were the controls. There was no difference between the groups in electrodermal activity and subjective tension for all video scenes, except for the one which portrayed the only pleasant interaction; the high-EE group was significantly more aroused on both measures, which were independent of each other.

The authors assessed the relevance of clinical symptoms to genetic research in schizophrenia in the nuclear families of 65 chronic schizophrenic probands. The morbidity risk for schizophrenia and schizotypal personality (a ‘spectrum’ disorder) was markedly reduced in first-degree relatives of probands with predominant negative symptoms, as compared with relatives of probands with other symptom patterns. The data support the notion that negative-symptom schizophrenia has an attenuated genetic component.

Research with schizophrenic out-patients has shown that antipsychotic medication reduces relapse rates. This protective factor may operate partially by raising the threshold for relapse in the face of environmental stressors such as life events and high levels of familial expressed emotion. A prospective, longitudinal design was employed in the monthly collection of life-events data with 23 recent-onset schizophrenic out-patients. In a between-subjects ANOVA, a significantly higher frequency of independent life events was found in the month prior to a relapse for ten patients on medication, as compared with the analogous month for 13 drug-free patients. These findings suggest that neuroleptic medication may produce a prophylactic effect by raising a patient's threshold of vulnerability to relapse.

The clinical and social characteristics of new long-stay (NLS) patients at Friern and Claybury hospitals are described, together with their accumulation rates within health districts in northeast London, and the associations between accumulation rates and social deprivation. There is a fourfold variation between local districts in annual accumulation rates of NLS patients (between 2.5 and 11 per 100 000 population); 0.55 of this variation is accounted for by the Jarman scores of social deprivation, and 0.81 by local rates of unemployment. Other recent British studies support this finding that measures of social deprivation can statistically explain a large proportion of the variation in treated rates of psychiatric morbidity, and may be useful in predicting needs for psychiatric services.

There has been almost a threefold increase in the incidence of suicide in Ireland during the past 20 years. When each case occurring between 1971 and 1988 was reviewed, the major causes of death were found to be drowning and hanging. Deliberate overdoses with tricyclic antidepressants accounted for less than 4% of all suicides, over the 17 years studied, and during this time, overdose with tricyclics has made a proportionately smaller contribution to the total number of suicides. Greater attention should be paid to identifying and treating the majority of suicidal patients who are at risk by other methods.

Studies of testosterone levels in patients with major depressive illness have produced varying results, plasma levels usually being reported. Saliva levels reflect ‘free’ plasma testosterone, and a pilot study of 11 men with major depression with melancholia, who underwent a standard dexamethasone suppression test, is described. There were no significant differences in testosterone levels compared with an age-matched control group. In the patient group, pre-dexamethasone levels correlated significantly and negatively with depression ratings on the 21–item Hamilton and the Montgomery and åsberg depression scales, and also with state anxiety measured on the Spielberger scale.

Fifty-five patients with primary major depression were followed up prospectively from time of onset of the index illness episode until recovery. The course of depression in hospital-treated patients was protracted, with a median length of episode of one year. Two factors significantly predicted persistence of symptoms: interval between onset and receipt of treatment, and premorbid neuroticism, which accounted for 55% of the variance in length of episode.

This study reports the demography, weight, and alcohol and psychiatric histories of the sexual partners of 112 consecutive patients with bulimia nervosa, all from an urban catchment area. Seventy-three patients (65%) had a current sexual partner. The partners were of similar social background, but slightly older. On average, partners were overweight (110% of MMPW) and over 27% reported having an eating or weight problem. A quarter of the partners had been treated for a psychiatric or emotional disorder. Nearly 40% drank more than 36 units of alcohol a week, and 14% had received treatment or consulted a doctor for alcohol-related problems. Heavy-drinking partners and multi-impulsive bulimics sought out each other. A quarter of partners had themselves been raised in a nuclear family in which a member had received psychiatric treatment; 12% had had a mother or sister with an eating disorder. Thirty-seven per cent of patients used a ‘safe man’, their fear of being hurt stemming from low self-esteem and a general sense of ‘failure’, and for 11% the relationship was abusive.

Among patients being treated for specific behaviour-control problems, there exists an important subgroup of ‘multi-impulsive’ patients whose treatment might be facilitated if the full range of their problems were recognised and dealt with as one general issue of impulse control. In women in particular, loss of control of eating may be prevalent and easily concealed from staff, and may thwart treatment. This survey of 50 women attending an alcoholic-treatment unit explored the prevalence of behavioural-control problems other than those of alcohol. Three-quarters of the women also had other behavioural problems. Over half the sample had thought of taking an overdose and just under half had actually taken one; about a quarter had cut themselves deliberately; half described impulsive physical violence; half acknowledged a period of ‘promiscuity’; and at least 16% had had a clinically diagnosable eating disorder. More research is needed but we believe that all self-damaging behaviour should be addressed simultaneously to prevent ‘revolving door’ relapses as emotional distress is transferred from one behaviour to another.

In-patients with psychotic symptoms and cannabis-positive urine analysis were assessed by PSE within one week of admission and again at one and six months. Concurrently admitted psychotic patients with drug-free urine analysis were controls. At one week the two groups differed significantly on only five PSE items: changed perception, thought insertion, non-verbal auditory hallucinations, delusions of control, and delusions of grandiose ability. One item (delayed sleep) differed at one month, and none at six months. The symptom cluster at one week is consistent with acute cannabis intoxication. Subjects and controls were mostly single, poorly educated, unemployed people with histories of psychotic disorders, and given major tranquillisers on admission. Compared with controls, subjects were younger, less likely to have psychiatric histories, more often male, Afro-Caribbeans with a history of convictions and compulsory admissions. The commonest diagnosis was schizophrenia. Use of the label ‘cannabis-induced psychosis’ may obscure a diagnosis of paranoid schizophrenia. A short-lived psychotic episode does occur in clear consciousness after cannabis intoxication, but chronic cannabis-induced psychosis was not found.

Relapse is a central problem in the treatment of addictive behaviour, and a specific problem in the out-patient treatment of the opiate withdrawal syndrome. This study investigated factors associated with relapse among 42 opiate addicts receiving out-patient detoxification treatment at a London drug-dependence clinic. All subjects completed a questionnaire about their social, psychological, and environmental circumstances in the week before interview, and were interviewed within the first two weeks of the programme. Forty per cent had lapsed to illicit heroin abuse within the previous week. Interpersonal factors and drug-related cues were associated with lapse to opiate use. Most subjects encountered a range of high-risk situations, such as regularly meeting other drug users and being offered drugs, and persistent negative mood states.

An exposure treatment for patients suffering from post-traumatic stress disorder (PTSD) is described. Image habituation training (IHT) involves the patient in generating verbal descriptions of the traumatic event and recording these onto an audiotape. After the initial training session with the therapist, homework sessions of self-directed exposure in which the patient visualised the described event in response to listening to the audiotape were carried out. Of ten consecutive patients who received this treatment, six improved considerably after ten homework sessions, two showed moderate improvements, and two showed minimal improvement on a range of outcome measures. There were significant decreases in anxiety between and within homework sessions, suggesting that habituation did occur and was responsible for improvement. Treatment gains were maintained at six-month follow-up.

A double-blind clinical trial of clomipramine versus phenelzine was carried out on 30 patients suffering from DSM–III obsessive–compulsive disorder. The study period was 12 weeks, and the maximum doses used (from the fifth week on) were 225 mg/day for clomipramine (14 patients) and 75 mg/day for phenelzine (12 patients); four patients dropped out. Obsessive symptoms improved significantly in both drug groups, but there was no significant difference between groups. Depressive symptoms improved before obsessive ones.

The total number of adults with Down's syndrome living in Leicestershire, ascertained by widespread enquiry, was found to be 378. Of these, 371 were matched with adults with mental handicap due to other pathologies, on the basis of age, sex, and type of residence. Those with Down's syndrome were found to have a different spectrum of mental disorders from those without the syndrome. In particular, Down's syndrome patients were more likely to have been diagnosed as having depression and dementia; the controls were more likely to have been diagnosed as suffering from conduct disorder, personality disorder, or schizophrenia/paranoid state. The same proportion of each group had been given a diagnosis of autism.

Through widespread enquiry, the population of adults with Down's syndrome (aged over 18 years) in Leicestershire was estimated at 376. For 315 of these (83.8%), the immediate carer was invited to complete the Adaptive Behavior Scale (ABS). Completed ABS assessments were obtained on 81.9% of the adult population with Down's syndrome in the county. Additional information concerning residential history was obtained. When the sample was divided into five cohorts on the basis of age when the ABS assessment took place, an exponential decline in ability was observed. Deterioration in most domains of the ABS achieved statistical significance in the cohort aged 50–59, and in all domains in those aged 60 and over. The deterioration in global skills in older cohorts was attributed to ageing (and thereby probably Alzheimer's disease). Institutional placement was associated with low scores in younger groups only.

Ten patients with multiple sclerosis (MS) and psychosis were assessed using the Present State Examination, and matched retrospectively with respect to age, disability, duration of symptoms, and disease type with 10 MS patients without psychosis. Both groups underwent MRI of the brain. There was a trend for the psychotic group to have a higher total lesion score, particularly around the periventricular areas. This reached statistical significance in the areas around the temporal horn. In all cases, neurological symptoms preceded the onset of psychosis. The psychotic group also had a later age of onset of psychosis than psychotic patients without brain disease. These results point to an aetiological association between the pathological process of MS and psychosis.

The psychiatric community seems determined to ground its medical legitimacy on principles that confuse diagnoses with disease. If mental illnesses are diseases of the CNS, they are diseases of the brain, not the mind. If mental illnesses are the names of (mis)behaviour, they are forms of behaviour, not diseases. Psychiatric metaphors have the same role in medicine as religious metaphors have in theology. Religion is, among other things, the institutionalised denial of a finite life. Psychiatry is, among other things, the institutionalised denial of the tragic nature of life: individuals who want to reject the reality of free will and responsibility can medicalise life, and entrust its management to health professionals. Psychiatrists have succeeded in persuading the scientific community, the courts, the media, and the general public that the conditions they call mental disorders are diseases, that is, phenomena independent of motivation or will. The more firmly psychiatrically based ideas take hold of the collective American mind, the more foolishness and injustice they generate. Long ago, the law makers agreed to let psychiatrists literalise the metaphor of mental illnesses. Thus, the Americans With Disabilities Act (AWDA), scheduled to be fully implemented by July 1992, covers claustrophobia, personality problems, and mental retardation, though unlike DSM–III–R it excludes kleptomania, pyromania, compulsive gambling, and transvestism. The literal language of psychiatry allows motivated actions to be called ‘diseases'. Other examples of behaviour for which psychiatrists have disease names, and which AWDA implicitly accepts as genuine diseases, include dysmorphophobia, multiple personality disorder, frotteurism, hypoactive sexual desire disorder, and factitious disorder with physical symptoms. However, it remains an open question whether premenstrual syndrome will achieve similar recognition in DSM–IV. Diseases occur naturally, whereas diagnoses are artefacts; why do psychiatrists make diagnoses?
