Children absence epilepsy（CAE）is one of age-dependent idiopathic generalized epilepsy，which occurs in 10% to 17% of all cases of epilepsy diagnosed in school-aged children. It is characterized by frequent typical absence seizures，and the electroencephalography（EEG）reveals characteristic bilateral，symmetrical，and synchronous discharges of 3 Hz generalized spike-and-waves（SWDs）on a normal background activity. This review summarized recent studies on children absence epilepsy，including pathophysiology，clinical electrophysiology，comorbidities，treatment，and prognosis. It is hoped that directions for further researches on this field could be determined.
