Post-stroke aphasia reflects cognitive deficits to memory or executive functions (Kuzmina & Weekes, 2017) as well as language impairments. It was also known that stroke cognitive profiles reflect the integrity of language functions and can serve as a criteria for the prognosis of rehabilitation (Yeung & Law, 2010). Following results of Kuzmina and Weekes (2107), we compared cognitive deficits in patients who have fluent and non-fluent aphasia. In this present study we used the Russian version of the Oxford Cognitive Screen (Rus-OCS; see Shendyapina et al., 2019) which is more potent (shorter) than the Birmingham Cognitive Screen used by Kuzmina and Weekes (2017).
Procedure. 25 individuals with fluent aphasia (58.65±16.26 years old, 10 females) and 23 patients with non-fluent aphasia (62.84±13.69 years old, 7 females) were assessed with the Rus-OCS and Russian version of the Montreal Cognitive Assessment (Rus-MoCA). Scores on subtests of attention, memory, praxis, language and number processing domains were recorded. The Kruskal-Wallis test was applied to examine differences between performance of both groups.
Results. Both groups had significant impairments in verbal functions, although they differed in subtests of reading, verbal recall, verbal recognition and episodic memory wherein patients with nonfluent aphasia were significantly more impaired in the subtest performance (p < 0.05).
Conclusions. Using the newly validated Rus-OCS, we identified an impairment to episodic memory and verbal functions in Russian speakers with non-fluent aphasia. These findings add to previous reports of the dissociations in cognitive impairment following brain damage for fluent and nonfluent patients with aphasia and in particular show the relevance of (brief) cognitive testing in the assessment of language impairments post-stroke. Theoretical implications will be discussed.
