7- Non- infectious meningitis:
It’s a term that refers to inflammation of the meninges due to causes rather than infectious agents. Non- infectious meningitis includes:
Drug-induced meningitis: some drugs might trigger meningitis in certain people, for instance, ibuprofen in some patients with lupus and immunoglobulin in a few chronic migraine patients. However, it’s still a very little chance.
Rheumatoid meningitis: a rare complication of the known autoimmune disease, rheumatoid arthritis.
Lupus meningitis: rarely affects patients with systemic lupus erythematosus (SLE), also an autoimmune condition.
Other causes, such as cancer and head injuries, can also cause non- infectious meningitis.
