Epilepsy with myoclonic absence presents with daily myoclonic absence seizures between 1 to 12 years of age. Other generalised seizure types which may be seen in this syndrome include generalised tonic-clonic seizures, clonic, atonic and typical absence seizures. Developmental impairment may be present at onset of epilepsy and may become more evident with age. The electroencephalogram shows regular three Hz generalised spike-and-wave pattern time-locked with myoclonic jerks, with a normal background. | Is a | False | Absence seizures present with a cessation of activity and impaired awareness associated with generalised spike and wave on EEG (electroencephalogram). An absence seizure is a generalised onset seizure and therefore, it originates at some point within, and rapidly engages, bilaterally distributed networks. | Inferred relationship | Some | |
A sudden onset, interruption of ongoing activities, a blank stare, possibly a brief upward deviation of the eyes. Usually, the patient will be unresponsive when spoken to. Duration is a few seconds to half a minute with very rapid recovery. An EEG (electroencephalogram) shows generalised spike-wave discharges during the event.
