Key Symptoms to Watch For
The classic signs of bacterial meningitis are fever, stiff neck, and altered mental state. However, not all patients have all three symptoms. Other common symptoms include severe headache, nausea, and sensitivity to light. If you experience these symptoms, especially if they come on suddenly, seek medical attention immediately.
How It's Diagnosed
Doctors diagnose bacterial meningitis by examining a sample of cerebrospinal fluid (CSF), obtained through a procedure called a lumbar puncture or spinal tap. The CSF is tested for signs of infection and inflammation. Blood tests and imaging scans may also be performed.
Treatment is Time-Sensitive
Bacterial meningitis requires prompt treatment with intravenous antibiotics. Delaying treatment can lead to serious complications or death. In some cases, doctors may start antibiotics even before confirming the diagnosis if bacterial meningitis is strongly suspected.
