Myoclonic astatic seizures are well known in children's generalized epilepsy. Some of our patients suffering from Parkinson's disease complained about sudden loss of postural reflexes together with dizziness or short loss of consciousness. When we looked into their electroencephalograms (EEG's), we found polyspikes and polyspike‐wave complexes that were seen especially after provocation by hyperventilation or photic stimulation. An additional therapy with sodium valproate diminished the myoclonic astatic attacks as well as the alterations in the EEG in all of the patients. None of them experienced a deterioration in their Parkinson's disease.
