Electroclinical features of absence seizures in sleep.

ABSTRACT

PURPOSE: To analyze electroclinical features of absence seizures during sleep. PRINCIPAL RESULTS: 30 children with genetic generalized epilepsy had 52 paroxysms of GSW >2s during sleep. 18/52 (35%) demonstrated a clinical sign. Ictal GSW lasted an average of 6.5s. CONCLUSION: Motor manifestations are seen during GSW>2s in sleep. 72% likely represent true ictal motor features while the rest may be serendipitous sleep phenomenon.
