Physical criteria of pathological processes. I. The modification of functional interhemispheric asymmetry at different stages of rheumatic diseases

The functional interhemispheric asymmetry of brain in patients with systemi c rheumatic diseases was estimated by measuring brain direct current potent ials. It is shown that different types of functional interhemispheric asymm etry correspond to different stages of systemic rheumatic diseases. At earl y stages, the left hemisphere asymmetry dominates, at expressed stages, the right hemisphere asymmetry is prevalent, and the terminal stage is charact erized by the loss of functional interhemispheric asymmetry.
