[Neuropsychological analysis of personality disorders in lesions of the frontal lobes of the brain].

The paper concerns some problems of disturbances in the most complicated forms of human behaviour and psyche in local brain lesions. A neuropsychological analysis of personality disturbances determines them as an integrative formation--a product of the work of the whole brain in social human activity. It is directed towards the distinguishing of "components" inside this formation and a study of the brain areas providing their functioning. In 63 patients with lesions of the left and right frontal lobes, as well as of deep areas of the right hemisphere, the authors studied the traits of self-evaluation (its 2 levels - cognitive: the knowledge of oneself, and emotional: feeling oneself) and emotional sphere. The data obtained indicate specific personality disorders with different localizations of brain lesions and, in particular, in lesions of the frontal lobe. Besides consolidated results given in the table, 2 cases (with pathology of the left and right frontal lobe) show principle differences in disorders of the emotional-personality sphere, related most likely to the localization of the pathological focus.
