Cognitive Deficiencies and Management of Aphasia

Michelle L. Kloc

There is growing evidence that many people with aphasia frequently exhibit co-occurring non-linguistic cognitive deficiencies in domains like attention, memory, executive skills, and learning, even though aphasia has typically been characterised in terms of language difficulties. According to some theories, cognitive deficiencies, such as those related to attention and working memory, are the root causes of language difficulty in aphasic individuals. Others contend that cognitive impairments frequently co-occur, are comparable to cognitive impairments in stroke patients without aphasia, and represent general brain dysfunction after damage. It is still unknown to what extent attentional and other cognitive deficiencies contribute to language problems in aphasia.
