Individuals without any prior EEG training can accurately determine whether the EEG represents seizures or nonseizure conditions

• Individuals without EEG training can detect ongoing seizures or seizure-like rhythmic periodic patterns by listening to sonified EEG
• Nonexperts listening to single-channel sonified EEGs detected seizures with remarkable sensitivity (students, 98%±5%; nurses, 95%±14%) compared to experts or nonexperts reviewing the same EEGs on visual display (neurologists,88%±11%; students, 76%±19%)
• Nonexperts listening to sonified EEGs rated them as seizures with high specificity (students, 85%±9%; nurses, 82%±12%) compared to experts or nonexperts viewing the EEGs visually (neurologists, 90%±7%; students, 65%±20%)
