Another study found elevated levels of CXCL-10 in CSF samples collected from patients who had inflammatory neurological diseases caused by COVID-19 (EDA, encephalitis, meningitis, meningoencephalitis, myelitis, and neuromyelitis optica) compared to a control group of patients who had non-communicable neurological diseases (infectious and non-inflammatory) from the pre-pandemic period (p < 0.01) [29]. This evidence concerns the gene CXCL10 and meningoencephalitis.
