title: Single photon emission computed tomography study of subclinical rhythmic electrographic discharge in adults.
abstract: Subclinical rhythmic electrographic discharge in adults (SREDA) is considered a benign EEG pattern of uncertain significance, although it may closely resemble an EEG seizure pattern. We investigated a 57-year-old man with a very lateralized epileptiform activity localized to the occipito-temporal areas of the right hemisphere. Neuropsychological tests, clonazepam injection and 99m Tc-HMPAO-SPECT were performed during the SREDA and compared to the interparoxysmal data, providing further evidence that SREDA cannot be considered as an epileptic pattern and that, in some instances, it may be related to chronic hypoxic/ischemic mechanisms.
