Cerebrospinal Fluid Biomarkers and Their Relevance to COVID-19 Neurological Manifestations
Understanding How COVID-19 Affects the Brain Through Key Protein Markers As the COVID-19 pandemic unfolded, it became clear that SARS-CoV-2, the virus behind the disease, does more than just affect the lungs. Increasing evidence suggests it also impacts the brain and nervous system—causing symptoms ranging from brain fog to confusion and even stroke-like events. But how exactly does this happen? A recent study titled "Elucidating SARS-CoV-2 Neurotropism: A Comprehensive Mendelian Randomization Study on Cerebrospinal Fluid Biomarkers and their Relevance to COVID-19 Neurological Manifestations" sheds new light on this critical question. https://www.researchsquare.com/article/rs-5574959/v1 What Are Cerebrospinal Fluid (CSF) Biomarkers? Cerebrospinal fluid (CSF) is the clear liquid that surrounds the brain and spinal cord, acting as a cushion and a messenger. When the brain experiences inflammation or damage, certain biomarkers—proteins that indicate biological changes—rise...
