Aseptic meningitis
Aseptic Meningitis
Aseptic meningitis (pronounced: uh-sep-tik men-in-jahy-tis) is a type of meningitis that is not caused by bacterial infection and usually resolves without treatment.
Etymology
The term "aseptic meningitis" is derived from the Greek words "a" meaning "not" or "without", "septikos" meaning "putrefactive", and "meningitis" meaning "inflammation of the meninges".
Definition
Aseptic meningitis is a condition characterized by inflammation of the meninges, the protective membranes covering the brain and spinal cord, which is not caused by bacteria but by viruses, fungi, parasites, or certain medications.
Symptoms
Symptoms of aseptic meningitis may include headache, fever, and stiff neck, similar to symptoms of bacterial meningitis. Other symptoms may include nausea, vomiting, sensitivity to light, and altered mental status.
Causes
Aseptic meningitis can be caused by a variety of factors, including:
- Viruses: Most cases of aseptic meningitis are caused by viruses, such as enteroviruses, mumps virus, and herpes simplex virus.
- Fungi: Fungal infections can also cause aseptic meningitis, although this is less common.
- Parasites: Certain parasites can cause aseptic meningitis.
- Medications: Some medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, and immunoglobulins, can cause aseptic meningitis.
Diagnosis
Diagnosis of aseptic meningitis involves a lumbar puncture to collect and analyze cerebrospinal fluid (CSF). The CSF is tested for bacteria, viruses, and other infectious agents.
Treatment
Treatment for aseptic meningitis typically involves managing symptoms, as the condition often resolves on its own. This may include rest, hydration, and over-the-counter pain relievers to manage headache and fever.
