Insights into Long COVID: Immunity, Neurological Symptoms, and Cognitive Deficits Explored

A new study has found significant immune system and nervous system changes in patients with Long COVID, which could explain the persistent neurological symptoms experienced by patients. The study used deep phenotyping to examine 12 patients with persistent neurological symptoms, revealing significant immune system changes, such as lower levels of CD4+ and CD8+ T cells and increased numbers of B cells and other immune cells. Furthermore, abnormalities in the autonomic nervous system were observed, indicating its involvement in Long COVID. These breakthrough findings may provide insight into diagnosing and treating Long COVID in the future.
