Presentation
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]
Bilateral ankle contractures were present. Both testes are palpable in the scrotum. The neurological exam showed the pupils were equal and sluggishly reactive to light. [medcraveonline.com]
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]
Dravet syndrome (DS) is a variant of epileptic encephalopathy that presents in infancy with gradually varying seizure types. [neurologyindia.com]
Designed to be read cover-to-cover, this highly practical reference covers basic science, assessment, and treatment and uses clear, succinct narratives, lists, tables, and illustrations to present the essential information needed to understand all aspects [books.google.com]
Workup
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]
Section three covers treatment with a thorough review of basic principles, all classes of antiepileptic drugs, stimulation therapy, surgery, and dietary and alternative therapies. [books.google.com]
Prognosis
Prognosis Children have a poor prognosis, experiencing developmental regression, and eventual severe mental retardation. [intechopen.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 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]
Etiology
Structural brain etiologies Genetic etiologies (STXBP1, SLC25A22, CDKL5, ARX, SPTAN1, PCDH19, KCNQ2, SCN2A and others) Metabolic etiologies (mitochondrial disorders, non-ketotic hyperglyinemia, pyridoxine/pyridoxal-5-phosphate disorders, carnitine palmitoyl [epilepsydiagnosis.org]
Etiology No clear etiology is found in approximately 40% of cases ( Hrachovy, 2008 & Vigevano, 1992). [intechopen.com]
The etiologic agent is also the cause of new variant Creutzfeldt-Jakob disease. [medical-dictionary.thefreedictionary.com]
Etiology EIEE may be the result of different etiologies. Many cases have been associated with structural brain abnormalities. [orpha.net]

Summary Epidemiology Incidence has been estimated at 1/100 000 births in Japan and 1/50,000 births in the U.K. 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]
Pathophysiology
The first section of the book introduces the clinical aspects of the science of epileptology with chapters on pathophysiology, genetics, classification, syndromes, epidemiology, etiology, and differential diagnosis. [books.google.com]
Pathophysiology The underlying mechanisms of these disorders are still poorly understood. [intechopen.com]
While these gene discoveries initially had no direct link to the more severe epileptic encephalopathies, they laid the general pathophysiological concept, such as the channelopathy concept of the human epilepsies [Steinlein, 2004], which eventually provided [karger.com]
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]

However, the high cost of the genetic analysis has prevented the parents from going ahead with the test. At present, the child is on a regular follow-up. He has recently been started on ketogenic diet. [neurologyindia.com]
