Neurobehavior and Brain Connectivity in Post COVID-19 Patients (NAUTILUS)
Cognition, Emotion/Behavior, Functionality and Brain Connectivity in Recovered COVID-19 Patients
Study Overview
Status
Conditions
Detailed Description
NAUTILUS is an observational, cross-sectional, and multicenter study. It will be performed at 22 public hospitals. Two groups of COVID-19 adults (Severe N=210, Moderate-mild N=210, WHO criteria) reporting cognitive complaints will compare to healthy controls (N=210). They will be assessed on neurobehavioral status. We will perform brain MRI in a subsample (N=120, 40 per group), and we will obtain potential biomarkers of neural damage (smell function, retinal blood plexuses integrity, and inflammation). Moreover, we will use machine learning-based algorithms based on demographics, previous pathologies, lifestyle, clinical data, and biomarkers to predict neurobehavioral models.
Expected results: Identify the neurobehavioral impact of post-COVID-19 individuals and the discriminative power of multimodal biomarkers in adverse outcomes. Our result would help develop clinically useful models to predict the neurobehavioral impact to develop future personalized and preventive intervention strategies.

Differences between groups in smell function
Time Frame: At the time of inclusion of the participant, between 3 and 12 months from the start of COVID-19

Smell function is evaluated with the University of Pennsylvania Smell Identification Test (UPSIT), which measures the individual's ability to detect odors at a suprathreshold level.
The UPSIT comprises four booklets, each of which contains ten pages.
An odorized "scratch & sniff" label is present on each booklet page.
The subject scratches the label and then indicates which of the four response alternatives best matches the perceived smell.
A score ranging from 6-18 means anosmia, 19-25 means severe microsmia, 26-30 in women and 26-29 in men means moderate microsmia, 31-34 in women and 30-33 in men means mild microsmia and a score of more than 34 in women and 33 in men means normosmia.
