Abstract

The importance of intermittent delta activity and periodic patterns in the electroencephalogram has intrigued neurophysiologists for decades. The clinical interpretations varied from nonspecific to suggested structural metabolic behavior, infectious and even epilepsy [1]. The most frequent clinical features were determined by clinical history of children with intermittent rhythmic delta activity and periodic patterns (January 2013-June 2017). Total 16 patients, Female 9 (56%). Periodic patterns: 25% (n = 4) PLEDs, 13% (n = 2) BiPLEDs and 6% (n = 1) GPEDs. Intermittent rhythmic delta activity: 50% (n = 8) FIRDAs and 6% (n = 1) OIRDAs. The most frequent causes of PLEDs were infectious and tumoral in 12.5% (n = 2) respectively. Tumor causes were the most frequent cause of FIRDAs 31% (n = 5), then neuroinfection12.5% (n = 2) and vascular 6% (n = 1). The most frequent periodic pattern was PLEDs and the most frequent intermittent rhythmic delta activity was FIRDAs, with more common etiologies tumor and neuroinfection, which is similar to the international literature [2,3].
