Cerebral spinal fluid<unk>  is generally the result of an immune response to neurovascular inflammation. Many cases point to a viral infection as the root cause of<unk> , in which the immune system produces antibodies against neuronal and vascular antigens. This evidence possibly connects it to viral meningitis and Mollaret’s disease. Certain non-viral infections, such as Lyme disease have also been considered possible causes. In some diseases, an infection precipitates an autoimmune response, leading to increased lymphocyte levels.
