Predictors of Post-COVID-19 Clinical and Cognitive Consequences

This pilot study will systematically collect data to assess if sleep disturbances and severity of sleep apnea comprises a modifiable facet of PASC. This study will be the first step towards collecting preliminary data for a larger, longer-duration and more comprehensive study regarding the relationships between long-COVID and sleep disturbances which can inform future healthcare strategies and clinical decision-making. The study will also explore whether inflammatory biomarkers levels during acute COVID infection predict severity and duration of long-COVID or PASC and sleep fragmentation post-COVID. Objectives: The overall goal of this project is to determine the associations between chronic post-COVID fatigue and sleep duration and sleep quality in patients after recovery from SARS-CoV-2 infection. The investigators have adopted the CDC definition for Post-COVID Conditions which persist for four or more weeks after SARS-CoV-2 infection and also is known as Post-Acute Sequelae of SARS-COV-2 infection (PASC). Specific Aim 1: Determine associations between sleep duration and sleep quality on PASC-related fatigue symptoms, cognitive function, biomarker levels and vigilance. Specific Aim 2. Determine if presence of obstructive sleep apnea (OSA) and level of PAP adherence during and prior to COVID-9 infection in patients with OSA predicts PASC- related fatigue, cognitive function and quality of life (QoL). Exploratory Aim: Determine whether partial or full/booster vaccinations with COVID-19 mRNA vaccine vs. no vaccination has an impact on chronic post-COVID fatigue and sleep disturbances.
