| Epileptic spasms are a sudden flexion, extension, or mixed extension-flexion of predominantly proximal and truncal muscles that is usually more sustained than a myoclonic movement but not as sustained as a tonic seizure. Limited forms may occur: Grimacing, head nodding, or subtle eye movements. Epileptic spasms frequently occur in clusters. Generalized-onset epileptic spasms originate at some point within, and rapidly engage, bilaterally distributed networks. |
