The purpose of this controlled clinical trial was to demonstrate possible correlations between changes in bioenergetic metabolism and psychotropic drug administration in the treatment of functional psychosis. The study included twenty-six patients, eleven with schizophrenia, three with chronic atypical depression and twelve with drug-resistant endogenous depressions. All patients were kept on continuous psychotropic medication for at least 3 weeks before starting the trial, and piracetam was given additionally in a fixed dosage of 2400 mg daily; the same number of identical capsules was given during the pre- and post-treatment placebo periods. Psycho-pathological evaluation of the patients was by the BPRS; clinical and biochemical data were evaluated statistically by the analysis of regression. The results show that in schizophrenic patients an improvement was observed in those cases who had improved biochemically, i.e. where the ATP values had increased. In drug-resistant depressions there was a rapid and significant clinical improvement after piracetam co-administration, and this went in step with a significant rise in ATP levels.

Clinicians who wait for disturbed adolescents to fulfil the diagnostic criteria for schizophrenia or a toxic psychosis will delay diagnosing a developing thought disorder until the youngster has been taught to be crazy and has become chronically stunted psychologically. Earlier diagnosis can allow more prompt prevention and support and can facilitate treatment and minimize handicapping. No single symptom is diagnostic of a developing thought disorder but thought disruption can be suspected when a cluster of persistent symptoms is present. These early manifestations of teenage thought disorder are presented and discussed.

A screening of 1462 individuals over 60 years of age in the general population of one of the districts of a large industrial city, detected 28 individuals (1,6% of all studied individuals), with mental disorders, which could be attributed to the schizophrenic spectrum. However, only in 8 cases (0,6%) they could be considered as psychotic forms of schizophrenia requiring active observation or treatment. In the remaining 15 cases (1% of the studied population) the psychotic states (productive disorders) were rudimentary, with a prevalence of deficitary changes. Most individuals with such disturbances were not in need of constant treatment or regular examinations in the dispensary.

Patients over 15 years of age from Turku hospitalized for psychosis for the first time during the years 1949-50, 1959-60 or 1969-70 were investigated. The incidence of hospitalized psychoses (per 100,000 inhabitants) was 115, 136 and 160, respectively. The increase in incidence was greater in women than in men. The incidence remained approximately the same in patients aged 30 to 59, but increased in the younger and older groups. The incidence of functional psychoses increased; in schizophrenia, however, it declined, while in paranoid and effective psychoses it increased. In organic psychoses, the admission frequency of psychoses of old age rose in the 1950's, but declined in some measure in the 1960's. The incidence of psychosis increased for single persons. The ratio of the incidence between single and married persons rose in men, whereas in women it fell. This was particularly pronounced in schizophrenics. The incidence of psychosis was highest in unskilled laborers. The overrepresentation of schizophrenia and paranoid psychoses seemed to have become more pronounced in this occupational group.

Conjugate lateral eye movements (LEMs) have been used as a measure of contralateral frontal hemisphere activation when individuals carry out reflective tasks. In a previous study, schizophrenics were noted to produce significantly more R-LEMs than controls suggesting that they use the left hemisphere in general more often than controls when initiating thought. More specifically, schizophrenics initiated thought on spatial emotional material in their left hemisphere more often than normals. In an effort to replicate these findings, the present study contrasted a new sample of 13 schizophrenics first with the original schizophrenic sample, and then with 13 psychotic depressives, and the original controls. In addition, other group comparisons are reported. The data obtained replicate the original findings of increased R-LEM (i.e., increased left hemisphere activity) and the excessive processing of spatial and to a lesser extent emotional material in the left hemisphere of schizophrenics. Psychotic depressives were found to initiate reflective tasks more often in their right hemisphere than either schizophrenic or the original sample of normal controls. Significant group differences among schizophrenics, normal controls, and psychotically depressed patients were obtained. The data are consistent with emerging concepts of a left hemisphere locus of disturbance in schizophrenia and right hemisphere disturbances in affective disorders.

In the survey of 74 Danish patients with temporal lobe epilepsy who underwent temporal lobectomy, a total of 20 patients were psychotic. Nine of these became psychotic during the follow-up period, six of them after cessation of their epileptic seizures. There were 13 schizophrenia-like psychoses, six paranoid delusional and depressive psychoses, and one childhood psychosis. Operation was on the right side in 39 and on the left side in 35 patients. When the various psychotic groups were compared with each other or with the nonpsychotic patients, the side of operation was not found to be statistically important. The patients with psychoses were older at operation and showed a higher rate of focal lesions in the resected specimens. Although more psychotic patients were bright or normally gifted, and had achieved a higher standard of schooling than nonpsychotic patients, their social status after operation was inferior. Surgery had no effect on psychosis present preoperatively nor on its possible postoperative onset. The diagnosis of psychosis was not considered to be contraindication to temporal lobectomy.

Serum acid glycosaminoglycans (GAG) levels were measured in 50 normals and 177 samples from different types of psychiatric patients. Mean levels were significantly higher in paranoid type schizophrenia, organic brain syndrome associated psychosis and manic type manic-depressive psychosis. The levels returned to slightly above the normal range upon partial remission in paranoid schizophrenics. In catatonic and hebephrenic schizophrenias the values were in the upper part of normal range. The levels were either in upper normal range or slightly higher in non-psychotic organic brain syndrome. In depressed type manic depressive psychosis levels were either lower than normal or in the lower part of normal range.

On the basis of the examination of patients with endogenic psychosis, indications were obtained that there are forms that mainly develop on a hereditary basis, and forms determined by psychosocial causes. In unsystematic schizophrenia the chief factors are hereditary, above all in periodic catatonia. On the other hand, there are a few indications of a hereditary genesis in systematic schizophrenia although it is just these forms that are distinguished by the severity of their course. By studying twins, cases of schizophrenia in infancy, and the circumstances of brothers and sisters, strong indications of psychosocial causes of systematic schizophrenia were found. Lack of contacts in the course of development appears to the determing factor. In motility psychosis, one of the cycloid psychoses, indications were found that excessive encouragement by other children can be a cause of overstrain and thus may be detrimental. The conclusions drawn are based on concrete findings obtained in a total of 1,114 cases and are for the most part statistically significant.

The family-heredity findings serving as criteria for the classification of functional psychoses are discussed, presenting recent data. The global morbidity risk of the resp. psychosis showing secondary cases similar (homotypical) to the index case and no increased incidence of cases of the other type may be interpreted by the theory of two separated genetically transmitted diseases (schizophrenias and affective disorders). The classical schizophrenic subtypes differ in their global schizophrenia morbidity risk and show a tendency toward homotypical secondary cases. Monopolar and bipolar affective disorders were found to be very close together concerning family-genetic data-Schizo-affective psychotics were found to have among their relatives the highest incidence of all types of functional psychoses at all, a high rate of schizophrenics (esp. catatonic type) and affective psychotics and no homotypical secondary cases.

The use for hallucinogenic purposes of an indigenous mushroom, Psilocybe semilanceata indigenous to Britain is reported in three patients. Typical psychedelic, transient psychotic and more prolonged schizophrenia-like states were seen, with sympathomimetic signs noted in two cases, in one being prolonged. Enquiry about such mushroom abuse should be considered in individuals presenting to medical or psychiatric emergency clinics.
