Twelve chronic in-patients with primary polydipsia were studied, during free drinking and after fasting, by concurrent measurements of plasma AVP, serum sodium and osmolality, and urine volume, AVP, osmolality, and creatinine. A majority of the patients showed inappropriately high levels of AVP: plasma AVP estimations demonstrated that seven had Type I SIADH and two had Type II SIADH. Urinary AVP estimations confirmed inappropriately raised AVP in seven of the subjects tested, and there was a significant agreement between the plasma and urine diagnoses. Although able to concentrate their urine in response to fluid deprivation, the patients showed a decreased renal sensitivity to AVP. Despite the mitigating effect of decreased renal sensitivity to AVP, the SIADH seen in these patients appears to contribute to the development of water intoxication caused by polydipsia.

The specificity and sensitivity of the HAD, 12-item GHQ and CIS were calculated by comparing the scores of dermatological patients on these tests with a criterion measure of disorder. Since psychiatry, along with many other branches of medicine, does not have an error-free criterion, it was assumed that the criterion was an underlying latent construct which was measured by all of the tests and could be derived by factor analysis from the scores on them. No differences were found between the two questionnaires (HAD and GHQ) in their ability to detect cases of minor psychiatric disorder although they were somewhat less reliable than the CIS.

Childhood precursors of symptoms of depression and anxiety were investigated in a national population sample of over 3000 men and women, aged 36 years. Early-life data had been collected prospectively for all subjects. A number of factors, differing for men and women, were found to be significant predictors of adult disorder. Some factors showed strong effects but tended to apply to relatively few individuals, while other more common circumstances had modest influences. Overall, early environment did not seem to hold great significance for adult affective disorder, although multiple disadvantages had a cumulative deleterious effect. There was little evidence of early benefits being protective.

Positron emission tomography (PET) differs fundamentally from computerised tomography (CT) and magnetic resonance imaging (MRI) in that it is a method for measuring function as opposed to structure. It is the most powerful tool available for the measurement of in-vivo brain function. This review describes the basic principles of the technique and its application to the study of brain metabolism in neurological and psychiatric disorder. The development of resting-state metabolic studies by the application of specific activation paradigms, a major current focus of the technique, is discussed.

Verbal and visuospatial memory and dichotic listening performance were examined in 15 acutely depressed patients with no history of ECT, 17 depressed patients currently in remission, 15 remitted depressed patients who had received ECT six months or more in the past, and 20 normal controls. The neuropsychological functioning of an additional group of 10 acutely depressed patients was also studied before and two weeks after ECT. The results revealed some evidence of logical and autobiographical memory impairment two weeks following ECT, but no evidence that ECT impaired dichotic listening ability. Rather, a normalisation of hemispheric laterality was apparent on the dichotic listening task following ECT and the concomitant relief from depression. There was also no evidence of cognitive dysfunction on any task in individuals who were tested six months or more following their last ECT treatment.

In an open study of 35 depressed patients, psychomotor disturbance, assessed by the CORE rating system, significantly predicted response to ECT in patients with a ‘retarded’ but not those with an ‘agitated’ type of illness. In multivariate analyses, psychomotor disturbance was the sole predictor of response. This preliminary study suggests that the CORE system, which has been shown to differentiate endogenous and non-endogenous depressive disorders, has predictive validity in relation to ECT response.

A three-year follow-up study of 49 psychiatric patients, representative of those found in long-stay care, tested whether behavioural, symptom and demographic variables as well as response-processing difficulties could predict levels of psychiatric care. The researchers were blind to the criteria for allocating patients to particular forms of care and the staff responsible for care had no access to information collected by the research team. Not only was it possible, using only these few factors, to predict the form of care, but one factor, response processing, was related to whether patients moved to more independent forms of psychiatric care.

When 20 female anorexic in-patients were investigated with weekly DSTs, 10 had an abnormal result at initial testing. There was no identifiable relationship between severity of weight loss and DST status; % ideal body weight was no different between suppressors and non-suppressors. There was no consistent relationship between normalisation of the DST response and weight gain. Depressive symptoms were common, with half the patients scoring 20 or more on the HRSD. Plasma ACTH concentrations before and after the DST were normal. There was a significant negative correlation between plasma dexamethasone concentrations and pre- and post-dexamethasone plasma Cortisol concentrations.

In order to study putative differences in central neurotransmitter function in depressive subtypes, serum Cortisol and prolactin responses to the putative serotonin agonist fenfluramine were examined in 30 subjects with major depression. Patients with endogenous depression (melancholia) as defined by each of ICD–9, DSM–III, RDC and Newcastle scale demonstrated a reduced prolactin response to 60 mg oral fenfluramine when compared with non-endogenous subjects. This was independent of either prolactin or Cortisol baseline levels, and indicates that there are differences in brain neurotransmitter function in the endogenous and non-endogenous subtypes of depression. Basal prolactin levels were reduced in bipolar compared with unipolar subjects, and delusional compared with non-delusional patients, although there were no differences in the prolactin responses to fenfluramine between these subgroups. Basal Cortisol levels and Cortisol response to fenfluramine did not distinguish between any of the subtypes.

A double-blind placebo-controlled trial of 23 chronic benzodiazepine users showed that overall, buspirone did not appear to be helpful in alleviating benzodiazepine withdrawal symptoms. Buspirone (5 mg t.d.s.) or placebo was administered for four weeks before, during and after diazepam withdrawal. Patients taking buspirone had a markedly higher dropout rate (seven out of 11) than those taking placebo (one out of 12). Mean daily diazepam dosage at entry was significantly higher in the buspirone group, but overall initial diazepam dosage was not related to outcome. Higher subjectively rated anxiety at the start of withdrawal was significantly related to higher dropout rate, irrespective of treatment, and was greater (although not significantly so) in the buspirone group.

Confirmation is reported of an earlier finding that the symptoms of patients with chronic schizophrenia segregate into three syndromes: psychomotor poverty (poverty of speech, flatness of affect, decreased spontaneous movement); disorganisation (disorders of the form of thought, inappropriate affect); and reality distortion (delusions and hallucinations).

In a controlled trial, 20 patients at high risk of repeated suicide attempts were randomly allocated to either cognitive-behavioural problem solving or a ‘treatment-as-usual’ control condition. The group practising problem solving improved significantly more than controls on ratings of depression, hopelessness, suicidal ideation and target problems at the end of treatment and at follow-up of up to one year, and there was evidence of an effect on the rates of repetition over the six months after treatment.

Computerised averaging methods have made it possible to extract and identify the electrical activity accompanying specific activities of the brain, including certain psychological processes, from the random background signals in electroencephalography (EEG). Event-related potentials (ERPs) and the way these change under various recording conditions are a powerful, non-invasive and relatively simple means of relating psychopathology to underlying physiology, and by comparing ERPs with imaging data it should be possible to compare electrical activity with changes in brain structure and blood flow in different disease states.

In a sample of 178 subjects with Alzheimer's disease, diagnosed by clinical criteria (NINCDS/ADRDA), delusions had occurred in 16% of the sample since the onset of the illness and been present within the last 12 months in 11%. Simple delusions of theft and suspicion were the most common types and a greater proportion of men suffered delusions of theft. Subjects with other types of delusion had relatively well preserved lateral ventricular size and basal ganglia calcification. Twenty per cent of the group had experienced persecutory ideation short of delusions since the onset of the illness. Cognitive function at entry to the study and cognitive deterioration over the succeeding 12 months was not influenced by the presence of disorders of thought content.

Published accounts of behavioural interventions for grief have relied on exposure and habituation to grief cues as the primary strategy. Such an approach is excessively narrow, since it does not adequately confront the challenges that are posed by a bereavement. Many people cope with a bereavement by themselves, and for those, intervention may well be counterproductive. A cognitive-behavioural intervention, following models for depression/anxiety, can assist vulnerable individuals obtain a more rapid or complete adjustment.

Accounts of the major DMSs are given using theoretical models of the functional components underlying recognition of familiar people. Thus, Capgras' syndrome is suggested to involve impairment of processes that can support ‘covert’ recognition of familiar faces in prosopagnosia. It therefore forms a potential ‘mirror image’ of the impairments underlying prosopagnosia, and earlier attempts to link the two conditions directly are questioned. Frégoli syndrome and intermetamorphosis are explained as defects at different stages of an information-processing chain. Not only are these accounts consistent with the association of different DMSs with different brain injuries, but they also offer both suggestions for new inquiries and predictions about possible preserved and impaired abilities.

Forty unipolar patients satisfying DSM–III criteria for major depression who discontinued lithium therapy were retrospectively compared with 105 similar patients who continued the drug and served as a control group. The time to readmission from starting lithium was compared while both groups were still on lithium, and after discontinuation in one group and further continuation in the control group. The progressive increase in the probability of recurrence over two years was the greatest after discontinuation of lithium. For the patients who eventually discontinued lithium, the cumulative probability of recurrence in two years was 0.08 on lithium and 0.58 after stopping it. The probability of recurrence was unchanged over the duration of the study for patients who continued to take lithium. There was no evidence of a lithium withdrawal syndrome within three months of stopping the drug. The results support the view that the everyday clinical use of lithium as prophylaxis is beneficial in unipolar depression.

In a sample of 178 patients with AD, visual hallucinations had been experienced by 13% and auditory hallucinations by 10%. Thirty per cent had misidentification syndromes; these were associated with a younger age and younger age at onset of illness, and proportionally more men than women were affected. There was a reduced 30-month mortality rate in this group. Subjects with hallucinations had a greater deterioration in cognitive function at 12-month follow-up, which could not be accounted for by neuroleptic medication.

Classical nosology has been the cornerstone of biological psychiatric research; finding biological markers and eventually causes of disease entities has been the major goal. Another approach, designated as ‘functional’, is advanced here, attempting to correlate biological variables with psychological dysfunctions, the latter being considered to be the basic units of classification in psychopathology. Signs of diminished DA, 5–HT and NA metabolism, as have been found in psychiatric disorders, are not disorder-specific, but rather are related to psychopathological dimensions (hypoactivity/inertia, increased aggression/anxiety, and anhedonia) independent of the nosological framework in which these dysfunctions occur. Implications of the functional approach for psychiatry include a shift from nosological to functional application of psychotropic drugs. Functional psychopharmacology will be dysfunction-orientated and therefore geared towards utilising drug combinations. This prospect is hailed as progress, both practically and scientifically.

Before receiving psychodynamic group psychotherapy at the Uffculme Clinic four groups of out-patients were assessed on the Claybury Selection Battery and the SCL 90, and therapists were asked to predict their progress. Outcome was assessed at about three months and one year by patients' self-reports of symptom change on the SCL 90 and therapists' ratings of progress. Only one of the three Claybury questionnaires, the TEQ, which measures attitudes to treatment, was significantly correlated with outcome, along with therapists' predictions. This result is different to that of a previous study which also found that outcome correlated with direction of interest (DIQ) and conservatism (C). The C and DIQ scales may provide useful predictive information only in a small proportion of cases.
