Cognitive-linguistic difficulties in COVID-19

Abstract

The COVID-19 pandemic has brought considerable death and economic hardship to populations around the world. Yet, its legacy may be in the form of Long COVID, a condition in which individuals who have had COVID infection continue to experience symptoms often for many months after their acute illness. One group of symptoms is described by sufferers as “brain fog”. This expression captures a constellation of complaints that are cognitive-linguistic in nature, with affected individuals reporting a significant impact of these problems on their occupational functioning and daily lives. This chapter reports the findings of case studies of two adults with Long COVID. Both adults enjoyed good health prior to their COVID infection. Neither was judged to be unwell enough to require hospitalization during the acute phase of their illness. Yet, they each reported an incomplete recovery and the persistence of debilitating symptoms over many months. The case studies provide a detailed account of their pre-morbid functioning and lifestyle, the onset and progression of their COVID illness, and a comprehensive analysis of their language skills. Both adults had intact structural language skills in the presence of high-level discourse difficulties. Specifically, they struggled to harness their strong skills in structural language to produce informative discourse, the transmission of which is an important pragmatic function of communication. The language profile associated with these cases of Long COVID is discussed in relation to other conditions that are assessed and treated by speech-language pathologists.
