Occurrence of Motor Seizure in aPatient With Cri-Du-Chat Syndrome: A Case Report

Abstract

This case report discusses A 6-year-old boy, a known case of Cri-du-chat (cat's cry) syndrome, who was referred to the epilepsy clinic of Imam Khomeini hospital for further evaluation and performing video EEG monitoring. Video EEG monitoring showed two stereotypical ictal clinical habitual events during sleep. These episodes were sudden and showed hyper motor movements in the left lower extremity. Electrographically, a definite ictal pattern evolved to rhythmic slow activity in the left centroparietal region. Brain MRI with epilepsy protocol was unremarkable. Due to the sudden onset of movements depicting hyper motor activity during sleep and abnormal EEG and the fact that the patient is a known case of the cri-du-chat syndrome, this is reported as having a motor seizure is extremely rare in cat cry syndrome. To our knowledge, this is the first report of motor seizure in cat cry syndrome.
