What Causes Aseptic Meningitis?
The most common culprits are viruses like enteroviruses and herpes simplex virus. However, there are over 100 possible causes, including other infections, medications, and even cancers. Think of your brain's protective layers as a fortress - various invaders can slip past the defenses and cause inflammation.
Recognizing the Symptoms
Key signs include fever, headache, stiff neck, and sensitivity to light. Unlike bacterial meningitis, mental status usually remains normal. Symptoms often develop over a few days, like a slowly building thunderstorm in your head.
How is it Diagnosed?
Doctors will perform a spinal tap to analyze your cerebrospinal fluid. They'll look for signs of inflammation and run tests to identify the specific cause. It's like CSI for your central nervous system - collecting clues to solve the mystery of what's causing your symptoms.
Treatment Options
Most cases resolve on their own with rest and supportive care. Antiviral medications may be used for certain causes. Antibiotics aren't effective against viruses but may be given initially until bacterial causes are ruled out. Treatment is like giving your immune system backup to fight off the invaders.
