Acomplex partial seizure typicallybegins with behavioralarrest and is followed by staring, automatisms, andpostictal confusion. A typical complex partial seizurelasts about 60-90 seconds and is followed by briefpostictal confusion. Secondarily generalized seizures: often begin with anaura that evolves into a complex partial seizureandthen into a generalized tonic-clonic seizure
Classification of Epileptic Seizures - Partial-onset seizures □ Complex partial seizure: Consciousness is impaired. A complex partial seizure typically begins with behavioral arrest and is followed by staring, automatisms, and postictal confusion. A typical complex partial seizure lasts about 60-90 seconds and is followed by brief postictalconfusion. □ Secondarily generalized seizures: often begin with an aura that evolves into a complex partial seizure and then into a generalized tonic-clonic seizure.
