Averaged cortical evoked potentials from single clicks were recorded from 51 patients and controls. The patient group consisted of 40 subjects with a diagnosis of 'nuclear' schizophrenia, and 11 subjects with diagnoses including mania, anxiety neurosis and personality disorder. Changes in auditory evoked cortical responses (AECR's) were most marked in clinically stable, dysphoric, chronic schizophrenics. These subjects showed reproducible, low amplitude, 'untidy' responses in which the amplitude of the primary peak was lower than the amplitude of later peaks. Chronic schizophrenics who were rated as being depressed, showed a more 'normal' AECR. AECR changes during the memorising of nonsense syllables demonstrated a functional separation between early and later peaks of the AECR. It was postulated that the AECR changes in schizophrenia and during memorising result from pathological patterns of cortical desynchronisation produced by altered mid-brain activity different from that of anxious arousal, and that the clinical 'steady-state' of chronic schizophrenia is reflected in the 'steady-state' desynchronisation changes in the AECR.

Birth patterns of non-aboriginal, first admission, Western Australian psychiatric patients born between 1920 and 1950 were compared statistically with those of the general population. Three I. C. D. categories were examined: schizophrenia, anxiety neurosis, and depressive neurosis. For both categories of neurosis no deviations from normal birth patterns were observed. For males, marked excesses in schizophrenic births were observed in June, and for females a similar excess occurred in September. Possible explanations for this sex difference are examined.

Analysis of a series of 600 psychiatric patients randomly selected from those attending a psychiatric clinic reveals that every single group of people shows its quota of psychiatric illness and all the major forms of illness are represented in a mixed society. From the present analysis it appears that Hindu patients are more careful for treatment than other religious groups and female patients were less frequently brought for treatment than their male counterpart. Patients coming from urban areas have many advantages over their rural counterpart in seeking scientific psychiatric treatment. Schizophrenia, affective disorders and anxiety neurosis were the three most common illnesses and these contributed to 77% of the total number of patients.

During a nine-month period (1974-75), 1,050 students (846 male, 204 female) at Ain Shams University, Cairo, attended the Student Health Centre. Fifty-two per cent were referred there by their general practitioners, 5 per cent by their families and 3 per cent through their faculties; the remainder (41 per cent) were self-referred. Male patients represented 2-8 per cent of the male students, but female patients only 0-9 per cent of the female students. In faculties dealing with practical subjects the male-female ratio was higher than in those dealing with more theoretical subjects. The diagnoses included anxiety neurosis (36 per cent of the cases), schizophrenia (18 per cent), depression (15 per cent) and neurotic depression (12 per cent).

Studies on the relationship between season of birth and mental disorder have been substantially confined to northern hemisphere regions. Such studies have generally found an excess of winter births of schizophrenics, and variably an excess of winter births of manic-depressive and mentally retarded patients. In the present study information on sex, diagnosis and date of birth was obtained on all 20,358 patients first admitted to psychiatric facilities in New South Wales between July 1970 and June 1974 and born in New South Wales. The collective 1962-71 monthly live-births for New South Wales were used as a control. A significant winter excess was found for the female schizophrenic group, while a significant spring excess was found for neurotic patients, most marked in those with anxiety neurosis. It is hypothesized that the relationship between schizophrenia and winter birth is consequent upon a greater sensitivity of schizophrenics to those physiological factors which determine conception in the general population.

A study was made of burns patients who were referred for psychiatric problems. There were a total of 69 subjects, divided into three groups. The first group comprised thirty-four cases who attempted suicide by burning themselves--there were more women than men, the majority were less than forty years, and Indians were overrepresented. The majority of these were suffering from schizophrenia or a major depressive disorder. The second group of twenty-three patients were those who had a non-psychotic psychological reaction to their burns. The majority were also less than 40 years of age, and the main reactions were anxiety neurosis or reactive depression. The third group of twelve patients were suffering from delirium. All were pyrexic and in eleven, infective agents were cultured. Some of them also had electrolyte abnormalities and two had respiratory burns.

Epilepsy was surveyed in the largest psychiatric hospital in the Santa Catarina State, southern Brazil. This establishment was designed for one thousand long-term beds but at the time of the survey there were 1126 inpatients. Diagnosis ranged from anxiety neurosis to schizophrenia although patients with epilepsy, with or without psychiatric symptoms were also admitted. The following aspects were analyzed: prevalence of epilepsy, seizure types, antiepileptic drug treatment and psychiatric diagnosis. 171 patients with epilepsy were identified (prevalence 152/1000), generalized tonic clonic attacks were the commonest seizure type and polytherapy was the standard treatment. In at least 85 of the epileptic patients there was no reason for prolonged institutionalization in a psychiatric environment. Moreover, most of the sample were prescribed large amounts of sedative drugs. A multidisciplinary approach and outpatients services are urgently required to improve the prognosis and well-being of patients with epilepsy who are referred to psychiatric care.

The Mini Finland Health Survey was an extensive epidemiological study of the Finnish population aged 30 or over; the prevalence of mental disorders was one aspect studied. Prevalence of symptoms in the General Health Questionnaire as well as the prevalence of self-perceived and clinically assessed mental disorders was studied. The total prevalence of clinically assessed mental disorders was 17.4%, 14.8% in the men and 19.5% in the women. A definite disorder was observed for 11.7% of the subjects. About half of the subjects suffering from a mental disorder according to clinical assessment also reported a self-perceived disorder. Of various diagnoses, the most common were phobic and anxiety neurosis (6.2%) and neurotic depression (4.6%). The prevalence of schizophrenia was 1.3%. The highest prevalence was found in the ages 50 to 64 years. The prevalence of psychoses was highest in northern and eastern Finland, and that of neuroses in southern Finland.

The paper presents experiences from one of the first psychiatric out-patients teams in Nicaragua which was started in 1982. 198 patients consecutively attending the unit were studied thoroughly as regards clinical diagnosis and areas of conflict presented as reason for attendance. Depressive neurosis and anxiety neurosis were the predominant diagnoses, followed by epilepsy and schizophrenic disorders. Almost half of the patients stated that they had family problems.

The function of the autonomic nerve system in sixty-seven patients with thoracic outlet syndrome was examined by a non-invasive and quantitative technique assessing the mean (M) and coefficient of variation (CV) or R-R interval in ECG. The first group of patients (28 cases) with autonomic nervous disorder and complaints of general discomfort showed a significantly shorter M and smaller CV. The second group (39 cases), those without general discomfort, exhibited a normal range of M and CV. In four of the first group with the diagnosis of schizophrenia and anxiety neurosis, furthermore, M and CV were nearly the same as those in the second group. In eight of the first group undergoing decompression operation, their complaints decreased or disappeared after surgery, with recovery of M and CV almost to the normal level. According to these results, this method appears to be useful in differentiating between autonomic nervous disorders and psychological disorders, facilitating disappearance of general discomfort due to autonomic nervous disorders.
