The inflammation of the protective membranes covering the brain and spinal cord is known as what?

Meningitis is the correct term for the inflammation of the protective membranes, known as meninges, that cover the brain and spinal cord. This condition can be caused by various infections, including viral, bacterial, or fungal agents, and it leads to swelling and irritation of the surrounding tissues. The symptoms typically include fever, headache, and a stiff neck and can become serious if not treated promptly.

In contrast, a stroke refers to a sudden loss of brain function due to a disruption of blood flow to the brain, whereas encephalitis is the inflammation of the brain itself, typically caused by viral infections. Multiple sclerosis is a chronic disease that affects the central nervous system by damaging the myelin sheath that surrounds nerve fibers. Understanding the distinctions between these conditions is vital, as they each involve different pathological processes and clinical implications.
