Epikarst is the uppermost, intensely weathered zone of karstified carbonate rock, also called the subcutaneous zone, acting as a perched aquifer that stores rainwater and regulates recharge to deeper karst.
Epikeratophakia
Epikeratophakia (epikeratoplasty, onlay lamellar keratoplasty): historical refractive corneal surgery introduced by Kaufman, Werblin, and Klyce at LSU around 1980, in which a prelathed donor corneal lenticule is sutured onto the de-epithelialized cornea to correct aphakia, myopia, or keratoconus; now largely abandoned.
Epilator
Epilator: an electric handheld hair-removal device that plucks many hairs at once by the root, first commercialized as Epilady in 1986 by Israel's Mepro; tweezer or spring types, results lasting about three to four weeks, painful at first, not permanent.
Epilepsy
Epilepsy, a chronic noncommunicable brain disorder also called a seizure disorder, is defined by recurrent unprovoked seizures. About 50 million people are affected worldwide; up to 70% could become seizure-free with antiseizure medicines, and surgery helps drug-resistant focal cases.
Epilepsy of infancy with migrating focal seizures
EIMFS, also called malignant migrating partial seizures of infancy, is a rare genetic epileptic encephalopathy with drug-resistant focal seizures migrating between hemispheres, onset before 6 months, KCNT1 mutations in many cases, and severe developmental impairment.

Epilepsy with auditory features
Epilepsy with auditory features (EAF), formerly ADLTE or ADPEAF, is a focal epilepsy syndrome with auditory seizures or receptive aphasia from lateral temporal onset, onset typically age 10-30, linked to LGI1 and other genes.
Epilepsy with eyelid myoclonia
Epilepsy with eyelid myoclonia (EEM), formerly Jeavons syndrome, a rare childhood-onset genetic generalized reflex epilepsy with eyelid myoclonia, eye closure and light triggers, photosensitivity, female predominance, and frequent drug resistance.
Epilepsy with generalized tonic-clonic seizures alone
Epilepsy with generalized tonic-clonic seizures alone (EGTCS, GTCA), formerly GTCS on awakening, is a genetic generalized epilepsy syndrome with tonic-clonic seizures as the only seizure type, onset at 5–40 years, and mandatory 3–5.5 Hz spike-wave on EEG.
Epilepsy with myoclonic absences
Epilepsy with myoclonic absences (EMA, ORPHA:86911, ICD-11 8A61.23) is a rare childhood-onset generalized epilepsy with rhythmic 3-Hz myoclonic absence seizures, male predominance, and variable prognosis.
Epilepsy with myoclonic-atonic seizures
Epilepsy with myoclonic-atonic seizures (EMAtS, Doose syndrome, myoclonic-astatic epilepsy) is a rare childhood epilepsy syndrome with myoclonic-atonic drop seizures, 2-6 Hz spike-wave EEG, male predominance, and remission in about two thirds of children.
Epilepsy-mild cortical malformation-oligodendroglial hyperplasia
MOGHE (mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy) is an ILAE-recognized cause of childhood drug-resistant epilepsy, defined by white-matter heterotopic neurons, Olig2-positive oligodendroglial hyperplasia, and somatic SLC35A2 variants.
Epileptic encephalopathies
Epileptic encephalopathies, now often termed developmental and epileptic encephalopathies (DEE), are severe epilepsies in which seizures and EEG epileptiform activity themselves worsen cognition and development; classic syndromes include West, Dravet, Ohtahara, and Lennox-Gastaut.
Epileptic encephalopathy with global cerebral demyelination
Epileptic encephalopathy with global cerebral demyelination, also called AGC1 deficiency or EIEE 39 (OMIM 612949), is a rare SLC25A12 mitochondrial aspartate-glutamate carrier disorder causing infantile seizures, hypotonia, arrested development, cerebral hypomyelination, low NAA, treatable with ketogenic diet.
