Summaries for Early Infantile Epileptic Encephalopathy

GARD : 20 Early Infantile Epileptic Encephalopathy (EIEE) is a neurological disorder characterized by seizures. The disorder affects newborns, usually within the first three months of life (most often within the first 10 days) in the form of epileptic seizures. Infants have primarily tonic seizures (which cause stiffening of muscles of the body, generally those in the back, legs, and arms), but may also experience partial seizures, and rarely, myoclonic seizures (which cause jerks or twitches of the upper body, arms, or legs). Episodes may occur more than a hundred times per day. Most infants with the disorder show underdevelopment of part or all of the cerebral hemispheres or structural anomalies. Some cases are caused by metabolic disorders or by mutations in several different genes. The cause for many cases can't be determined. There are several types of early infantile epileptic encephalopathy. The EEGs reveal a characteristic pattern of high voltage spike wave discharge followed by little activity. This pattern is known as "burst suppression." The seizures associated with this disease are difficult to treat and the syndrome is severely progressive. Some children with this condition go on to develop other epileptic disorders such as West syndrome and Lennox-Gestaut syndrome.

MalaCards based summary : Early Infantile Epileptic Encephalopathy, also known as early infantile epileptic encephalopathy with suppression bursts, is related to developmental and epileptic encephalopathy 4 and dravet syndrome. An important gene associated with Early Infantile Epileptic Encephalopathy is STXBP1 (Syntaxin Binding Protein 1), and among its related pathways/superpathways are Retrograde endocannabinoid signaling and GABAergic synapse. Affiliated tissues include brain, eye and cortex, and related phenotypes are intellectual disability and global developmental delay

Disease Ontology : 12 A neonatal period electroclinical syndrome that is characterized by tonic spasms and partial seizures.

NINDS : 53 Ohtahara syndrome is an uncommon type of epilepsy characterized by hard to control seizures and developmental delays.  The disorder affects infants, usually within the first three months of life (most often within the first 10 days) in the form of epileptic seizures. Infants have primarily tonic seizures (stiffening of the muscles, upward eye gaze, dilated pupils, and altered breathing), but may also experience focal seizures (involving only one area or side of the brain), and rarely, myoclonic seizures (involving sudden muscle jerks). Ohtahara syndrome is classically caused by very abnormal brain structure that may be due to damage or abnormal development.  It also can be due to metabolic disorders or genetic epilepsy syndromes, although the cause or causes for many cases can’t be determined. Recent studies suggest that there is often an identifiable genetic cause of Ohtahara syndrome. Electroencephalography recordings of brain activity of infants with Ohtahara syndrome reveal a characteristic pattern of high voltage abnormal brain activity alternating with periods of very little activity.  This pattern is known as “burst suppression.”

KEGG : 36 Early infantile epileptic encephalopathy (EIEE) is characterized by frequent tonic spasms of early onset within a few months of life, and a suppression-burst pattern in electroencephalography (EEG). Many causes have been considered for EIEE. It has been reported that 75% of the cases subsequently evolve to West syndrome, and later a much smaller number progress to Lennox-Gastaut syndrome.
