Increased brain dopamine and reduced glutamic acid decarboxylase and choline acetyl transferase activity in schizophrenia and related psychoses.

Dopamine, glutamic acid decarboxylase (G.A.D.) and choline acetyltransferase (C.A.T.) were measured in four regions of post-mortem brains. 41 patients with the hospital diagnosis of schizophrenia (psychotic group) were compared with a control grout normal in the putamen. G.A.D. activity was significantly reduced in the psychotic group, by about 50% in the nucleus accumbens, amygdala and hippocampus, and by about 30% in the putamen. C.A.T. activity was significantly lower in nucleus accumbens from the psychotic group, but normal in other brain regions. From an assessment of case notes, "schizophrenia" was distinguished from "schizophrenia-like psychosis". The biochemical findings for these subgroups were essentially similar, although C.A.T. activity in nucleus accumbens and hippocampus from the schizophrenic group was significantly lower than in controls. It is of brain are associated with schizophrenia and schizophrenia-like psychoses, although whether such neurochemical abnormalities are related to the illness or are a consequence of prolonged treatment with neuroleptic drugs remains unclear.

The case of Arise Evans: a historico-psychiatric study.

The life and the ideas of a mentally aberrant figure in mid-seventeenth century England are presented in relation to the sociocultural background of the time and the available clinical information. The material illustrates the need to draw on both sources when applying psychiatric concepts to particular historical epochs.

Pollution, noise, and mental health.

Though the adverse psychological effects of noise as an environmental pollutant are well recognised, much of the relevant work has been focused on the ambiguous concept of "annoyance". The relation between noise and mental ill-health calls for more direct investigation. In particular, the pronounced individual variation in reactions to noise requires elucidation.

Mental health care in the community: an evaluative study.

A study was designed to assess the therapeutic value of attaching a social worker to a metropolitan group practice in the management of chronic neurotic illness. The psychiatric and social status of a group of patients before treatment and after one year was compared with the status of a control group treated more conventionally over the same period. The results indicate that the experimental service conferred some benefit on the patient population.
