Abstract:
Objective To investigate the clinical and electroencephalogram (EEG) features of patients with idiopathic generalized epilepsy in adults with phantom absences.Methods Six patients were referred to the clinic of epilepsy from April,2007 to December,2011.They all had clinical assessment,EEG,or video EEG confirming absences seizure.Results Six patients showed the following similar clinical-EEG features:(1) mild ictal impairment of consciousness associated with generalized 3.0-3.5 Hz spike and slow wave discharges; (2) late-onset generalized tonic-clonic seizures; (3) absence status epilepticus with or without secondary generalized tonic-clonic seizures; (4) generalized discharges were mostly seen in three types in the awaking stage:fragmented discharge (＜4 s),brief discharge (4-10s) and long-time discharge (＞ 10 s).None of the patients had myoclonic jerks or photosensitivity.One patient' s mother had a history of generalized tonic clonic seizures.One patient had a history of children absence epilepsy and one patient had a history of febrile convulsion in the age of 1-3.Conclusion Idiopathic generalized epilepsy with phantom absences has distinct clinical and EEG features and may become a new idiopathic generalized epilepsy syndrome in adults.
