[Speech disorders in right-sided brain stroke].

The clinical picture revealed that right-sided brain stroke is often accompanied by some speech disturbances. The present paper aims at the analysis of literature devoted to speech disturbances in right-sided brain stroke. The paper addresses issues on lateralization of speech functions, in particular the role of the right hemisphere in speech activity and structure of speech pathology in right hemispheric foci are specified. Such clinical variants of speech disturbances as aphasia, disprosodia, dysartria, mutism and stammering are analyzed in depth. Types of speech disorders as well as possible mechanisms of their formation in dependence of the lesion localization on the brain axis (cortex, subcortical structures, stem, cerebellum) and size of brain lesion are reviewed.
