[The general intelligence factor: psychometric study. Approach to the problem of mental deterioration].

The authors have measured the correlation coefficient between W.B. and P.M. scores in 80 normal subjects, comparable for age and school. A mutual relationship between the two tests, connected by the hypothetical general intelligence factor "g", was really demonstrated. Correlation coefficient was positive and significative between W.B. total scores, excepted verbal scores, and P.M., the highest one between subtests 8, 9 and P.M. The intra-tests correlation between W.B. total scores and each subtest score was also evaluated: between sub-tests 8, 9 and W.B. total scores the highest one again. A new qualitative interpretation of mental deterioration in clinical neurology and psychiatry is suggested on the base of these results.

[Neuropsychological aspects of schizophrenic mental deterioration].

The authors have administered a test of intelligence (WAIS) and a test of attention (Color Naming) to a group of patients affected by chronic schizophrenic impairment. The scores give shape to a picture of mental deterioration, especially characterized by a decrease of attentive power. This results validates the possibility of a neuropsychological approach to the etiopatogenesis of schizophrenia and supports the hypothesis that an impairment of mental synthesis power may explain both clinical and psychometric features of the disease.

[Altered plasma lipid and protein patterns in schizophrenic patients (author's transl)].

The plasma lipid and lipoprotein pattern (total cholesterol, triglycerides and total lipid concentration; electrophoretic separation of the lipoproteins) and plasma protein profile (total protein concentration; electrophoretic separation of the plasma proteins) have been determined in a group of 60 chronic schizophrenic patients (47 men and 13 women, mean age 30,3 +/- 22 years). When compared to a control group matched for age and sex, the schizophrenic patients exhibited significantly lower cholesterol concentration and altered distribution pattern of the plasma lipid fractions. Similarly, the plasma a1,- a2,- and beta-globulin patterns are also altered in schizophrenic group. It is concluded that the altered plasma lipid and protein patterns may suggest that (auto)-immunologic and/or metabolic factors may be involved in the pathogenesis of schizophrenic disease.
