A polydiagnostic approach to the differences in the symptoms of schizophrenia in different cultural and ethnic populations.

This study evaluates the pathoplastic influences of ethnicity and culture on the symptoms of schizophrenia. A sample of 113 schizophrenics was evaluated using the Present State Examination (PSE) and Landmark's Manual for the Assessment of Schizophrenia. The subjects were 57 coloured and 56 black individuals. Six different tribes of Bantu, Negroid and Khoisan origin and with different language and cultural backgrounds were represented among the black subjects. Core symptoms remained basically the same in two groups, but the content of positive symptoms was found to be influenced by culture. However, no statistically significant differences in the presentation of negative symptoms were found in terms of quantity, but there were qualitative differences between the ethnic groups.

EEG changes measured by spectrum analysis under hyperbaric conditions.

The EEG activity was followed during simulated diving to 20 m depth. Altogether 49 EEG records of 5 min length were taken in 5 divers breathing compressed air in a close system. No significant changes of the EEG could be found during either compression or decompression if only conventional indicators, such as the amplitude of theta activity, were tested. However, a complex "normality ratio," based on multivariate analysis of a normal material, was capable of showing significant impairment of the brain activity during the decompression. The indicator has been designed to reflect the abnormality level rather than the short-lasting EEG changes, the latter being mostly dependent on the alertness fluctuations. The EEG changes associated with alertness fluctuations were assessed separately by means of a specific "alertness indicator" and a prominent alertness increase was found during both compression and decompression phases of the diving experiment.

EEG changes under hyperbaric conditions: spectral analysis during simulated diving.

Continuing investigations of the influences of the hyperbaric pressure upon EEG record in divers during simulated diving. The hyperbaric ecological system exerts influences on brain bioelectric activity manifesting itself by changes of alpha frequency and appearance of slow waves. The changes in the brain activity are mostly observable at the changes in chamber pressure values. The changes in EEG recordings are smallest at constant pressures. EEG examination can be used as a measure of the safety of newly developed decompression schedules.
