Abstract

Intermittent rhythmic delta activities are electroencephalographic discharges with uniform morphology, at a frequency of 4 Hz or less, containing at least six cycles, lost by eye opening and stimulation. These are called "plus" if concomitant theta or higher frequency rapid activity or spike, sharp wave activity is present. This group has a stronger relationship with epileptiform abnormality. We aimed to discuss the clinical presentations, and nomenclature of intermittent rhythmic delta activities with three case reports.
