Metadata[+] Show full item record
The sensitivity of electroencephalogram (EEG) for the diagnosis of suspected epilepsy in adults is 29% to 55%. Sensitivity can be increased to 80% to 90% with use of serial EEGs. The specificity in healthy patients is generally 99.5%. (SOR A, based on multiple diagnostic cohort studies.)
