Eponymous epileptic encephalopathies

  • Dravet syndrome: severe myoclonic epilepsy of infancy
  • Doose syndrome: myoclonic astatic epilepsy
  • Harel-Yoon syndrome (HYS)
  • Kohlschütter-Tönz syndrome (KTS): epilepsy, dementia and amylogenesis imperfecta
  • Landau-Kleffner syndrome (LKS)
  • Lennox-Gastaut syndrome (LGS)
  • Ohtahara syndrome: early-infantile epileptic encephalopathy
  • Pitt-Hopkins syndrome (PTHS): this is caused by TCF4 gene mutations
  • Poirier-Bienvenu syndrome: this is caused by CSNK2B gene mutations
  • Vici syndrome
  • West syndrome: infantile spasms
