The relationship between language disorder and the non-language-based cognitive function in patients with aphasia after stroke

Post-stroke aphasia refers to acquired language disorder caused by cerebrovascular disease. As part of cognitive function, language is closely related with other non-linguistic cognitive function.In recent years, many scholars have begun to pay attention to the relationship between language disorder and non-verbal cognitive function in patients with post-stroke aphasia. This paper describes the epidemiology of cognitive impairment in patients with post-stroke aphasia, and summarizes the relationship between language obstruction and the non-language-based cognitive function in patients with aphasia after stroke (such as working memory, attention, execution, etc.) to provide a direction for further research. Key words: Stroke; Aphasia; Language disorder; Non-language-based cognitive
