Viral Infections of the Nervous System

Viral infections of the nervous system occur when viruses invade the brain and spinal cord, potentially leading to serious illnesses. Common examples include meningitis, which is the inflammation of protective membranes around the brain, and encephalitis, the inflammation of the brain itself. Symptoms may include headache, fever, confusion, and seizures. These infections can be caused by various viruses, such as enteroviruses, herpes simplex virus, or the West Nile virus. While some infections resolve on their own, others may require medical treatment, making early diagnosis and care essential for better outcomes.
