[Several methodologic aspects of the problem of aphasia].

Main concepts of aphasia are analysed. It is shown that each of them emphasizes analytically certain aspects of this complicated problem. It is maintained that the one-sided view on this problem is overcome historically in the context of developing dialectico-materialistic understanding of the scientific psychophysiological problem. It is proven that the intergrative methods of investigating speech functions are, of the greatest diagnostic value.

[Insufficient excitation for speech in focal lesions of non-specific brain structures].

On the basis of a study of 150 patients with focal lesions of the mesencephalo-diencephalic brain areas the authors discuss speech disorders, appearing due to disturbances in the functions of the activating nonspecific systems. They indicate that these speech disorders are conditioned by an insufficiency of speech volition. However, in communicative important situations for the patient they can be overcome. In development of mesencephalodiencephalic pathology the syndrome of insufficient speech volition may be transmitted into a clinical picture of akinetic mutism. The problem of differentiation of insufficiency speech volition is being discussed in relation to lesions on different levels of the activizing nonspecific system and the accompanying drop of speech activity of the motor-aphatic and disarthric disorders.

[Neurologic pathology in severe forms of chronic renal failure].

The paper deals with the results of a neurological and psychological study of 162 patients with chronic renal insufficiency. Among this contingent 122 were in a terminal phase and preserved a viability only because of a long-term (up to 4 years) regular hemodialysis. The authors describe the dynamics of neurological pathology due to autointoxication and metabolic disturbances and suggest that the main foci of lesions are nonspecific structures of the mesencephalo-diencephalic brain areas and peripheral nerves on the background of a diffuse lesion of the nervous tissue.
