Angelman syndrome is also called happy puppet syndrome.It is firstly reported by British sci-entist in 1965.It is a chromosome disorder disease,mainly of chromosome 15q11-13 regional anomaly.The An-gelman syndrome patients are often accompanied by mental retardation and special features,90% with epilepsy and the specific electroencephalogram patterns,and the prognosis is unfavorable.The diagnosis of Angelman syn-drome depends mainly on genetic testing,but some patients with genetic testing may show no abnormalities, these patients need referring the clinical diagnosis and the distinctive electroencephalogram.Before the distinctive clinical manifestation and genetic testing,the abnormal electroencephalogram can help diagnose Angelman syn-drome in advance,thereby improving the early detection rate of the disease.This review is mainly to summarize the electroencephalogram patterns in Angelman syndrome in recent years.
