The aim of our study was to investigate the prevalence and associations of cognitive impairment in COVID‐19 survivors in the post‐acute setting. Method Our study is conducted in three post‐COVID‐19 outpatient clinics in tertiary hospitals in Greece. Eligible subjects included previously hospitalized COVID‐19 survivors with mild to moderate disease, returning for follow‐up at least two months post‐discharge. Exclusion criteria included intensive care unit admission, intubation, a history of neurodegenerative disease and other significant comorbidities. Study measurements included demographics, clinical evaluation, medical, family history, anthropometrics, 6‐minute walk test (6MWT), 30 seconds sit‐to‐stand (30STS), handgrip strength, spirometry, Pittsburgh Sleep Quality Index (PSQI), the Montreal Cognitive Assessment (MoCA), reactive oxygen metabolites (dROMs) and plasma antioxidant capacity (PAT). Cognitive impairment was considered on MoCA ≤24. Result 142 COVID‐19 survivors were included in the study (110 Male, 32 Female; Mean age of 56.16±10.92). A total of 47.2% presented with cognitive decline (CD) as indicated by a MoCA score ≤24. Cognitive decline prevalence by SARS‐CoV‐2 variant of concern (VOC) was 39.5%, 50% and 62.5% for Alpha, Beta and Delta, correspondingly. A binary logistic regression model controlling for age, gender and VOC indicated that the diffusing capacity for carbon monoxide (DLCO) was independently associated with MoCA ≤24 (p = 0.014, OR = 0.669, 95%CI: 0.484‐0.923). Compared to severe untreated OSAS (n = 28), distinct domains but similar prevalence of cognitive impairment was noted. Conclusion Diffusion capacity abnormalities for carbon monoxide in COVID‐19 survivors as noted in other studies, may be implicated in the development of cognitive impairment.
