Meningitis is an inflammation of the meninges that surround the brain and spinal cord. It can be caused by viruses, bacteria, fungi or parasites. Common symptoms include fever, neck stiffness, vomiting and photophobia. Diagnosis involves examining cerebrospinal fluid through lumbar puncture. Treatment focuses on antibiotics, antivirals or antifungals as well as managing symptoms. Nursing care aims to enhance cerebral perfusion, reduce fever and pain, maintain fluid balance, and help the patient return to normal functioning.
