[Role of structures in the left temporal lobe of the brain in the etiology of emotiono-affective disorders in epileptics].

The characteristics of the constant emotional background and of paroxysmal affective disorders were studied in a series of 226 patients with temporal epilepsy, including 131 who had undergone either open or sterotaxic surgery. According to the nature of the emotional pathology, all the patients were divided into four groups. Noticeable dependence was ascertained between the intensity of emotional changes and the extension of the epileptogenic zone. The emotional-affective pathological manifestations noted in patients with the right-side versus left-side localization of the epileptogenic focus are compared. A conclusion is drawn that the localization of the epileptogenic focus (foci) in the mediobasal temporal formations of the left hemisphere causes more frequent and pronounced disorders of the emotional behaviour in patients suffering from different epileptic paroxysms.
