title: Intermittent rhythmic delta activity (IRDA) in a patient with band heterotopia.
abstract: We report a patient with band heterotopia whose electroencephalogram (EEG) showed typical morphological features of intermittent rhythmic delta activity (IRDA). This 18-year-old woman had complex partial seizures. Neuropsychometry revealed mental dysfunction. Magnetic resonance imaging (MRI) showed bilaterally symmetrical layer of heterotopic gray matter in deep white matter over the frontal, parietal and occipital regions. This case is the first report of IRDA detected in band heterotopia.
