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]

Abnormal neurological behavior may be present prior to onset of seizures. Severe developmental delay is seen, with or without regression. Children with this syndrome may evolve to have West or Lennox Gastaut syndrome. [epilepsydiagnosis.org]

Dravet syndrome (DS) is a variant of epileptic encephalopathy that presents in infancy with gradually varying seizure types. [neurologyindia.com]

The diagnostic workup of EIEEs remains challenging because of frequent difficulties in defining etiologies. [dnatesting.uchicago.edu]

We identified 26 patients with Infantile Epileptic Encephalopathy (IEE) of unknown etiology despite extensive workup and without any specific epilepsy syndromic phenotypes. [journals.plos.org]

Diagnostic workup In early myoclonic encephalopathy, EEG is characterized by a "burst-suppression" pattern with bursts of spikes, sharp waves, and slow waves, which are irregularly intermingled and separated by periods of electrical silence. [intechopen.com]

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]

Treatment outlook is poor. Anticonvulsant drugs and glucocorticoid steroids may be used to try to control the seizures, but their effectiveness is limited. [ipfs.io]

Hope for children with Ohtahara Syndrome relies on the medical and research community understanding more about the causes and what treatment may work best in OS. The Rare Epilepsy Network (REN) helps connect families with research in these areas. [epilepsy.com]

Moreover, early recognition and management of seizures may help improve the overall clinical outcome, although unlikely to have an impact on long term prognosis. [medcraveonline.com]

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

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]

It is important to recognize PCH type 1 as a possible underlying etiology for Ottahara syndrome, also, the presence of Ottahara syndrome should help distinguish PCH type 1 from other types of spinal muscular atrophy. [medcraveonline.com]

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

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

Pathophysiology The epileptic encephalopathies are a group of age-specific epilepsy syndromes of diverse etiologies that share the potential for causing significant cognitive impairment. [emedicine.medscape.com]
