Definition

A migrating focal seizure is a seizure that involves different body parts, usually without overlap, in a consecutive manner so that the offset of a seizure in one part coincides with its onset in another, even shifting multiple times between the sides of the body. They can be associated with autonomic manifestations. [from HPO]

Disease or Syndrome
Developmental and epileptic encephalopathy-79 (DEE79) is a severe neurologic disorder characterized by onset of refractory seizures in the first months of life. Affected individuals have severely impaired psychomotor development and may show hypotonia or spasticity. Brain imaging may show hypomyelination, cerebral atrophy, and thinning of the corpus callosum (summary by Butler et al., 2018 and Hernandez et al., 2019). For a general phenotypic description and a discussion of genetic heterogeneity of DEE, see 308350.
