abstract = {Cohort studies that quantify volumetric brain data among
individuals with different levels of COVID-19 severity are
presently limited. It is still uncertain whether there
exists a potential correlation between disease severity and
the effects of COVID-19 on brain integrity. Our objective
was to assess the potential impact of COVID-19 on measured
brain volume in patients with asymptomatic/mild and severe
disease after recovery from infection, compared with healthy
controls, using artificial intelligence (AI)-based MRI
volumetry. A total of 155 participants were prospectively
enrolled in this IRB-approved analysis of three cohorts with
a mild course of COVID-19 (n = 51, MILD), a severe
hospitalised course (n = 48, SEV), and healthy controls (n =
56, CTL) all undergoing a standardised MRI protocol of the
brain. Automated AI-based determination of various brain
volumes in mL and calculation of normalised percentiles of
brain volume was performed with mdbrain software, using a 3D
T1-weighted magnetisation-prepared rapid gradient echo
(MPRAGE) sequence. The automatically measured brain volumes
and percentiles were analysed for differences between
groups. The estimated influence of COVID-19 and
demographic/clinical variables on brain volume was
determined using multivariate analysis. There were
statistically significant differences in measured brain
volumes and percentiles of various brain regions among
groups, even after the exclusion of patients undergoing
intensive care, with significant volume reductions in
COVID-19 patients, which increased with disease severity
(SEV > MILD > CTL) and mainly affected the supratentorial
grey matter, frontal and parietal lobes, and right thalamus.
Severe COVID-19 infection, in addition to established
demographic parameters such as age and sex, was a
significant predictor of brain volume loss upon multivariate
analysis. In conclusion, neocortical brain degeneration was
detected in patients who had recovered from SARS-CoV-2
infection compared to healthy controls, worsening with
greater initial COVID-19 severity and mainly affecting the
fronto-parietal brain and right thalamus, regardless of ICU
treatment. This suggests a direct link between COVID-19
infection and subsequent brain atrophy, which may have major
implications for clinical management and future cognitive
rehabilitation strategies.},
