Brief Summary

This project aims to investigate executive functioning abilities (primary outcome) and quality of sleep (secondary outcome) in patients with COVID-19 (while distinguishing between those with and without sleep fragmentation), compared with an age- and education matched control group of healthy individuals who did not experience contagion. Prefrontal electrical activity will be recorded with EEG in patients, and related to sleep and cognitive-executive metrics.

The main questions it aims to answer are:

* is executive functioning impaired in COVID-19 patients compared with individuals who were not infected?

* is there a relationship between altered sleep and impaired executive functioning in COVID-19 patients?

* is such relationship related to altered prefrontal brain activitity in COVID-19 patients?

Detailed Description

While impaired executive functioning has been often reported in association with COVID-19 contagion, it is still unclear whether, and to what extent, executive deficits might be explained by an altered quality of sleep, that been also frequently reported in COVID-19 patients. On this basis, this project aims to investigate executive functioning abilities (primary outcome) in patients hospitalized for a COVID-19 contagion, while distinguishing between those with and without sleep fragmentation (quality of sleep; secondary outcome), compared with an age- and education matched control group of healthy individuals who did not experience contagion. To this purpose, 38 COVID-19 patients and 38 healthy controls will be administered questionnaires and cognitive tasks aimed to assess: a) executive functioning/inhibitory control (GoNogo task); b) quality of sleep (NOSAS; Insomnia Severity Index; Epworth sleepiness scale). Prefrontal electrical activity will be recorded with EEG in COVID-19 patients, and related to sleep and cognitive-executive metrics. Statistical analyses will be aimed to investigate: a) a possible decrease of executive skills in COVID-19 patients compared with healthy controls, and in COVID-19 patients with fragmented sleep compared with those with normal sleep; b) possible differences in the relationship between executive performance and quality of sleep across the three experimental groups; c) whether possible differences in such relationship relate to prefrontal brain activity in patients. The results of this study will provide novel insights into the consequences of COVID-19 at the cognitive level, thus informing about treatment strategies.
