Abstract

Objectives: The purpose of this paper is review of research on the co-occurrence of exe-
cutive dysfunction in patients with aphasia after stroke. Review: Aphasic speech disor-
ders and cognitive dysfunctions are frequent consequences of the irregularities in the
blood flow within the brain. Aphasia, apart from language deficits, may be accompanied
by non-linguistic cognitive disorders. More and more often the co-existence of speech
disorders of aphasia and the disorders of executive functions are considered. The role of
executive functions is connected with the processes of planning, creating strategies,
monitoring actions, self-regulation, and integration of various cognitive modalities.
These activities are undoubtedly coupled with the process of speech generation. There-
fore, the effective communication depends on the integrity of executive functions. Conc-
lusions: In the present paper the author has presented a survey of researches on the
executive functions disorders and aphasia after stroke. In the researches the author has
evaluated the level of executive functions with the application of neuropsychological
methods as well as compared those results in terms of various aspects of verbal functio-
ning, capability to communicate and conducting conversations among people with apha-
sia. In addition, as studies argue, the efficiency of executive functions has a significant
impact on the effectiveness of aphasia rehabilitation.
