“…The trends from more focal to more generalized seizures with advancing age have been reported separately in either children or in adults (Nabbout et al, 2008;Akiyama et al, 2010;Ragona et al, 2010;Bureau and Dalla Bernardina, 2011). Inconsistent results about focality of seizures were found in adult patients with DS.…”

“…Previous studies have primarily focused on describing seizures exclusively either in children or in adults. Seizures the results between the studies largely incomparable (Nabbout et al, 2008;Akiyama et al, 2010;Gaily et al, 2013). For example, generalized tonic-clonic seizures (GTCS) were reported in nearly all of the patients in earlier studies (Jansen et al, 2006;Ragona et al, 2010), while other studies either did not see GTCS (Bureau and Dalla Bernardina, 2011) or described this seizure type less frequently (Caraballo and Fejerman, 2006;Catarino et al, 2011).…”

“…Parameters include; longitudinal bipolar montatge, sensitivity 15 lV. (Nabbout et al, 2008;Bureau and Dalla Bernardina, 2011). A more recent study also indicated that seizures in DS have discordant EEGs where seizures classified as generalized convulsive seizures could have a focal ictal EEG pattern (Akiyama et al, 2010).…”

“…Common characteristics of Dravet's syndrome in animal models and patient groups are increased interictal epileptiform discharges or epileptic seizures due to sensitivity to increased body temperature and increased seizure frequency and severity due to aging [12, 13, 26, 28]. The above-mentioned characteristics refer to juvenile form of Dravet's syndrome and are based on solid evidence from several studies.…”

Epileptic encephalopathies are motor-mental retardations or cognitive disorders secondary to epileptic seizures or epileptiform activities. Encephalopaties due to brain damage, medications, or systemic diseases are generally not in the scope of this definition, but they may rarely accompany the condition. Appropriate differential diagnosis of epileptic seizures as well as subclinical electroencephalographic discharges are crucial for management of seizures and epileptiform discharges and relative regression of cognitive deterioration in long-term followup. Proper antiepileptic drug, hormonal treatment, or i.v. immunoglobulin choice play major role in prognosis. In this paper, we evaluated the current treatment approaches by reviewing clinical electrophysiological characteristics of epileptic encephalopathies.

ten Clinical note Reversible causes for epileptic spasmsDrugs such as theophylline 57 or anti-allergic agents of hista mine H 1 -receptor antagonists, particularly ketotifen, 58 may induce epileptic spasms and hypsar rhythmia that are entirely reversible upon drug withdrawal.Pyridoxine dependency, which is treatable, can in rare instances present with epileptic spasms. This is most likely when other seizure types have occurred before the onset of spasms. 46 AetiologyThe aetiology is multiple and diverse. Aetiologically, West syndrome is classified, in order of preva lence, as symptomatic (about 80% of all) due to discernible organic insults, and cryptogenic or idiopathic
