Moreover, a recent study demonstrated that the chemokine CCL11, associated with impairments in cognitive function and neurogenesis, remains elevated in long COVID-19 patients experiencing cognitive symptoms compared to those without cognitive symptoms, suggesting an inflammatory response contributing to cognitive deficits.9 Thus, cytokines may become useful as inflammatory markers for cognitive impairments after SARS-CoV-2 infection. The gene discussed is CCL11; the disease is Cognitive impairment.
