Case Report

Summary: Subclinical rhythmic discharges of adult (SREDA) is a rare benign EEG variant in adults and is of unknown clinical significance. Its occurrence in children is extremely rare. In review of the literature, it has been described in only four children. We present a case of a 10-year-old female with generalized idiopathic childhood absence epilepsy who is noted to have SREDA in three subsequent EEGs performed across a 25-month span. She had no clinical change with these discharges and it was believed to be a benign variant. Including our patient, three of four children with SREDA presented with generalized epilepsy leading to the conclusion that, although rare, SREDA is more common in children presenting with generalized epilepsy.
