The study of infancy can provide us with new models for the genesis and treatment of psychiatric disorders. It allows us to observe development and can elucidate the contribution the internal and external world make to mental health and disorder. It can also help to define and describe developmental pathways which may be instrumental in creating a resilient or vulnerable adult.

Issues concerning the use of predictive and screening instruments include the difficulties posed by temporal changes in the base rates for the behaviour of interest, the possible advantages of using three rather than the customary two risk categories, and the desirability of specifying in advance the proportional sizes of the risk subgroups. A method is proposed for constructing and assessing tripartite risk scales, and a new scale for predicting the repetition of parasuicide, with the results of a prospective validation study, is reported.

The performance of CAMCOG, the cognitive section of the CAMDEX, is compared in a non-random sample of 222 elderly people with diagnoses based on agecat and on DSM–III criteria, and with the MMSE and some short rating scales. With a cut-off point of 69/70 and agecat organic syndrome as the criterion, the sensitivity of CAMCOG was 97% and the specificity 91%. However, 21% of DSM–III diagnoses of dementia scored above this cut-off; these were mostly mild cases. The correlation between CAMCOG and MMSE scores was 0.87, and the advantage of CAMCOG may be more apparent in longitudinal studies. Multivariate analyses showed that CAMCOG scores are affected by age, sociocultural factors and hearing and visual deficits in addition to dementia, but not by depression. There was a suggestion that individual subsections are differentially affected.

Evidence is presented concerning the concurrent validity of the Interval General Health Questionnaire. This was used to describe the timing and course of spells of depression and anxiety symptoms in first-year medical students over their initial six months at university. A small subgroup of students who were continuously symptomatic were distinguished from other groups by the presence of a number of factors: they were slow to make friends, had inappropriate support from relatives, had a tendency to have rows, had steady girl/boyfriends and had ‘vulnerable’ personalities. By contrast, a large subgroup who were well throughout had experienced caring childhood backgrounds, seldom had girl/boyfriends, showed little tendency to have rows and had ‘resilient’ personalities. Other subgroups are also described. It is suggested that students who suffer from chronic minor symptomatic distress could be recognised early on and offered appropriate support from counselling services.

A study of 50 opiate addicts attending a London service for treatment of drug dependence found that 47 subjects had previously made at least one attempt at self-detoxification. These subjects reported 212 previous attempts. Although 30 subjects reported having managed to complete at least one attempt, the success rate per episode was low (24%). One of the most commonly reported methods, used by 28 subjects, involved an abrupt cessation of opiates (‘cold turkey’). Of the drugs used in their attempts at self-detoxification, benzodiazepines were reported by 24 subjects and opiates by 20. Practical strategies such as distraction and avoidance were also used. Self-help detoxification materials for opiate addicts might be useful.

A random community sample of subjects aged 65 and over was re-interviewed after three years by psychiatrists using the GMS and HAS. The relationship between drinking history and current psychiatric morbidity was examined. Men with a history of heavy drinking for five years or more at some time in their lives were found to have a greater than fivefold risk of suffering from a psychiatric disorder at the time of the interview. Among this group past alcohol consumption was significantly higher for those with a current psychiatric diagnosis compared with those who were well. This association between heavy alcohol consumption in earlier years and psychiatric morbidity in later life is not explained by current drinking habits.

Computerised tomography (CT) was used to assess the possible effects of substance abuse on brain morphology. Polydrug abusers had significantly wider third ventricles than normal controls, with a positive correlation between age and ventricle:brain ratio (VBR). Assuming no effect of age, estimated quantity of substance abuse was not significantly related to ventricular and sulcal measures, except that alcohol consumption correlated positively with VBR and severity of cocaine use correlated negatively with sulcal width. When age of the subjects was partialled out, alcohol use showed a tendency for association with VBR; however, severity of cocaine use did not remain a significant predictor of cortical sulcal width. The findings suggest that chronic use of alcohol, but not necessarily of other commonly abused substances, produces brain atrophy.

A cohort of first-generation Asian immigrants who received a diagnosis of a functional psychosis at the Bethlem Royal and Maudsley Hospitals were compared with an English-born control group. The Asians were found to have spent a lower total percentage of time in the two hospitals, had fewer in-patient admissions per year, and had a shorter average duration of stay in hospital than the matched controls.

Positive and negative symptoms at admission and discharge of 401 unselected schizophrenic patients from four psychiatric hospitals around China were studied. On admission, 58% of patients had prominent negative symptoms and the overall severity of negative symptoms was similar to that of positive symptoms; at discharge, negative symptoms were more prevalent and more severe. The severity of negative symptoms was not significantly correlated with duration of illness or with dosage of medication; 48% of first-episode, drug-naive patients had prominent negative symptoms on admission. Negative symptoms responded to standard neuroleptic treatment, but the improvement was less marked than that in positive symptoms (47% v. 80%). The proportion of patients classified as positive type, negative type, and mixed type schizophrenia altered dramatically with treatment. These findings highlight the importance of negative symptoms in the assessment and treatment of both acute and chronic schizophrenia.

A prospective study was conducted of all referrals to the emergency psychiatric service of an inner-London hospital over one year. There were 53 individuals who presented with the specific and spontaneous complaint of suicidal ideation without any accompanying act of self-harm. The main diagnoses in this group were personality disorders (40%) and alcohol dependence (15%); only 13% were suffering from depressive illness. Members of the group differed from the other 369 presenters to the service in that they were less likely to be accorded a diagnosis of a defined mental illness, twice as likely to have a criminal record, and more likely to have a previous history of deliberate self-harm. A quarter of the suicidal complainants were admitted to hospital following assessment.

Various areas of social adjustment were compared using the Social Adjustment Scale in 27 remitted bipolars, 24 remitted unipolars and 25 normal controls matched for age and sex. Scores for global adjustment and for social and leisure activities were significantly worse in patients than in controls. The maladjustment in social and leisure activities appeared only in ‘contact with friends' for bipolar patients and ‘diminished social interactions' for unipolar patients. Unipolar patients differed significantly from controls on the items investigating sexual adjustment. In unipolars, social maladjustment seemed to be independent of the course of the disease; in bipolars, it was partly related to the mean number of lifetime episodes and current residual symptoms.

The present study examined the socio-demographic, clinical, cognitive, social behaviour and social network characteristics of the 97 patients in contact with the COSTAR programme – a mobile treatment and case management service for the long-term mentally ill in inner-city Baltimore. Compared with shorter-contact patients, those in contact for more than one year showed no change in symptoms, or in cognitive or global function. They did manifest improved social function, especially for slowness, personal hygiene and posturing. The long-contact group showed improvements in the quality and quantity of their social networks. Our results suggest that a home-based treatment system can help patients to reverse a vicious cycle of social isolation and to establish supportive social contacts.

In a comparison of nutritional management (NM) and stress management (SM) for treatment of bulimia nervosa, 55 female patients were randomly assigned to either treatment. Therapy consisted of 15 sessions in a group over three months, by the end of which, patients under both treatment conditions showed a significant reduction in the frequency of binge eating and vomiting and a significant improvement in various psychopathological features such as body dissatisfaction and depression. All improvements were maintained over 12–month follow-up. NM produced a more rapid improvement in general eating behaviour, a faster reduction in binge frequency and a higher abstinence rate from binge eating. SM led to greater positive changes in certain psychopathological features such as feelings of ineffectiveness, interpersonal distrust and anxiety. NM should be regarded as a necessary first intervention in all bulimic patients. Further psychological therapy, such as SM, is indicated as well for some patients, depending on their specific psychological difficulties.

Subjects admitted to hospital with post-partum psychoses were compared with matched normal postpartum controls using two neuroendocrine challenge tests: dexamethasone suppression of Cortisol and TRH stimulation of TSH. Post-dexamethasone Cortisol levels were significantly elevated. There were less-clear hints of blunting of TSH response. In the small samples there was no obvious association of abnormalities with any particular diagnoses within the range of mania, psychotic depression and schizoaffective disorders.

The relationship between schizophrenic ‘spectrum’ disorders and affective illness was studied in the nuclear families of 90 chronic schizophrenic probands. An increased risk of schizophrenia and related disorders was demonstrated among the first-degree relatives of probands with a family history of major affective disorders. Conversely, relatives of probands with a family history of schizophrenic ‘spectrum’ disorders were at a greater risk of affective illness (major depression) than relatives of probands with no family history. These results lend support to the notion that a subset of affective disorders is associated with the liability to schizophrenia.

“41 (33%) of 123 patients with acute psychiatric disorders (DSM III diagnosis of major depression or schizophrenia) had borderline or definite folate deficiency (red-cell folate below 200 μg/l) and took part in a double-blind, placebo-controlled trial of methylfolate, 15 mg daily, for 6 months in addition to standard psychotropic treatment. Among both depressed and schizophrenic patients methylfolate significantly improved clinical and social recovery. The differences in outcome scores between methylfolate and placebo groups became greater with time. These findings add to the evidence implicating disturbances of methylation in the nervous system in the biology of some forms of mental illness.”
