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.
