Introduction

Cognitive functioning and psychological well-being are considered negatively affected by COVID-19. An estimated 15%-40% of COVID-19 patients report disrupted cognitive performance. Higher rates of anxiety, depression and sleep disturbances are also reported post infection.

Objectives

We examined the profile of cognitive changes in a group of adults with a confirmed COVID-19 diagnosis, compared to those without a COVID-19 diagnosis (cross-sectional between-subjects investigation); and for a subgroup, compared to their pre-COVID-19 cognitive function (longitudinal within-subjects investigation).

Methods

One hundred and twenty-one adults (57 with no known history of COVID-19; 64 with confirmed COVID-19; 17/64 with long COVID symptoms) were assessed online for psychological well-being and cognitive function (attention, processing speed, working memory, episodic memory and executive function). Pre-COVID-19 cognitive data were available for 56 of 121 adults (24 adults with a confirmed diagnosis of COVID-19; 22 with no known history of COVID-19) through the MyCognition database.

Results

The COVID-19 group showed reduced processing speed in both cross-sectional and longitudinal investigations, and also showed significant attentional impairment when examined cross-sectionally. Five long COVID symptoms (abdominal pain, chest pain, sore eyes/conjunctivitis, sore throat and vomiting/nausea) were associated with reduced performance in multiple cognitive domains. Higher levels of depression and anxiety were also present in the COVID-19 group but these symptoms were mostly unrelated to cognitive performance.

Conclusions

COVID-19 survivors, especially those with long COVID symptoms, are very likely to experience cognitive disruption. Measures need to be implemented to support their cognitive recovery in addition to the physical recovery.

No significant relationships.
