Epileptic Encephalopathy, Early Infantile, 14; Eiee14

Description

Early infantile epileptic encephalopathy-14 is a severe neurologic disorder characterized by onset in the first 6 months of life of refractory focal seizures and arrest of psychomotor development. Ictal EEG shows discharges that arise randomly from various areas of both hemispheres and migrate from one brain region to another. The disorder presents as 'malignant migrating partial seizures of infancy' (MMPSI), a clinical designation (summary by Barcia et al., 2012).For a general phenotypic description and a discussion of genetic heterogeneity of EIEE, see EIEE1 (OMIM ).
