What is the primary effect of meningitis?

The primary effect of meningitis is inflammation of the meninges, which are the protective membranes covering the brain and spinal cord. This inflammation is typically caused by an infection—either viral, bacterial, or fungal—and leads to a range of symptoms, including fever, headache, and neck stiffness. The term "meningitis" itself is derived from the word "meninges," highlighting that the central issue in this condition is the inflammatory response in these protective layers.

The complications that arise from the inflammation can impact various neurological functions, potentially leading to headaches, seizures, and other serious health issues. Addressing the inflammation is crucial for treatment, as it can rapidly progress and result in severe consequences if left untreated.
