How is meningitis defined?

Meningitis is defined as the inflammation of the protective membranes, known as the meninges, that surround the brain and spinal cord. This condition typically occurs as a result of an infection, which can be caused by viruses, bacteria, or fungi, leading to symptoms such as headache, fever, and neck stiffness. Recognizing meningitis is crucial because it can progress rapidly and lead to serious complications if not treated promptly. The focus on the protective membranes emphasizes the critical nature of this anatomical area in relation to the central nervous system. Understanding this definition is essential for paramedics and healthcare providers in order to recognize and manage the condition effectively in a prehospital setting.
