Diagnosis [ edit ] The diagnosis is based on the clinical presentation and on typical electroencephalographic patterns. [19] Treatment [ edit ] Treatment outlook is poor. [en.wikipedia.org]

No single cause has been identified, although in many cases structural brain damage is present. [2] Characteristics Ohtahara syndrome is rare and the earliest-appearing age-related epileptic encephalopathy, with seizure onset occurring within the first [ipfs.io]

Clinical description Onset of EIEE occurs within the first 3 months of life but some present within the first few weeks after birth. [orpha.net]

Prognosis Children have a poor prognosis, experiencing developmental regression, and eventual severe mental retardation. [intechopen.com]

The disease prognosis is very poor, with most affected children either dying or being severely neurologically impaired. [cags.org.ae]

Prognosis Prognosis is poor with death usually occurring in infancy (50% before age of 2). Survivors have severe psychomotor impairments with continuing seizures. The documents contained in this web site are presented for information purposes only. [orpha.net]

Prognosis The prognosis is related to the underlying disorder. The severity of developmental impairment varies with the type of epilepsy. Early infantile epileptic encephalopathy (Ohtahara syndrome) The prognosis is very poor. [emedicine.medscape.com]

The prognosis is severe. Early myoclonic encephalopathy and Ohtahara syndrome together are recognized as 2 of the epileptic encephalopathies seen in early infancy and characterized by suppression burst on electroencephalogram. [medlink.com]

Establishment of the etiology has important implications for prognosis and genetic counseling. [content.iospress.com]

Etiology No clear etiology is found in approximately 40% of cases ( Hrachovy, 2008 & Vigevano, 1992). [intechopen.com]

In this updated article, the authors review the clinical and neurophysiological data, management, and etiologic factors. [medlink.com]

Etiology EIEE may be the result of different etiologies. Many cases have been associated with structural brain abnormalities. [orpha.net]

The developmental prognosis partially depends on the etiology. When classified by etiology, normal development was described in 51% of cryptogenic cases versus only 6% of symptomatic cases. [emedicine.medscape.com]
