What is Menin­gi­tis?

Wellness Update - - Meningitis -

Menin­gi­tis is in­flam­ma­tion of the meninges that re­sults in swelling of brain tis­sue and some­times spinal tis­sue (spinal menin­gi­tis). Swelling in­hibits the flow of blood and oxy­gen to brain tis­sue. The char­ac­ter­is­tic symp­toms of menin­gi­tis are stiff neck, se­vere headache, and fever. The meninges are three ul­tra­thin mem­branes that sur­round and pro­tect the brain and a por­tion of the spinal cord: the outer mem­brane (dura mater), mid­dle mem­brane (arach­noid), and in­ner mem­brane (pia mater). Menin­gi­tis is ei­ther in­fec­tious (con­ta­gious) or non­in­fec­tious. In­fec­tious menin­gi­tis is clas­si­fied as vi­ral, bac­te­rial, fun­gal, or par­a­sitic, de­pend­ing on the type of or­gan­ism caus­ing the in­fec­tion.
