Subclinical rhythmic electrographic discharges of adults (SREDA) is a distinctive electroencephalogram (EEG) pattern seen in adults and is thought to have little clinical significance. These patterns are generally considered nonspecific. We evaluated a 45-year-old female patient with migraine in whom SREDA seemed to have a temporal relation to the migraine symptoms of the patient.
