COGNITIVE-LINGUISTIC MECHANISMS AND METHODS FOR MONITORING THE RECOVERY OF BRAIN FUNCTIONS IN VIOLATION OF CEREBRAL CIRCULATION (for example transcortical motor / dynamic / aphasia)

Abstract

The article describes and analyzes the cognitive-linguistic mechanisms of brain function restoration in patients with dynamic aphasia, as well as the description of an objective way of results monitoring. Actualization of propositional structure, implicitly represented in a derived word, can contribute to the restoration and coherent thinking, as well as the elimination of agrammatism in speech. Work with derivative words, produced and reproduced within the boundaries of word-formation types and niches, propositionally bound within the nest, polysemy and synonymy, seems effective in dynamic aphasia. Any derivative word is a convolute discourse; while comprehending it, a person can link together different actants using predicate. For patients with dynamic aphasia it is often difficult to build a coherent text according to a given picture or to retell the meaning of a given passage. By analyzing the composition derivative words and explaining their meanings while repeating the speech of a specialist, or by deploying those situations which are implicitly represented in the derivatives, the patient masters, or rather "remembers", the mechanism of coherent speech generation. Reliance on the personal factor in the ongoing psycholinguistic experiments allows one to restore speech in stroke patients more quickly. Objective assessment of the speech-mental activity of patients and results of rehabilitation is possible by the magnetic resonance scan of brain function mode with measurement of blood oxygenation level and the local cerebral blood flow in certain areas of brain activation.
