We correlated the composite scores of the cognitive domains with several biomarkers that have been suggested to be altered in patients with COVID‐19 (Samprathi & Jayashree, 2020), including: C‐reactive protein (CRP) levels, aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), creatine kinase (CK), hemoglobin (Hg), platelets, leukocytes, lymphocytes, D‐dimer, ferritin, and interleukin‐6 (IL‐6). The gene discussed is GPT; the disease is COVID-19.
