BACKGROUND Recent development of genetic analyses enabled us to reveal underlying genetic causes of the patients with epileptic encephalopathy in infancy. Mutations of voltage-gated sodium channel type I alpha subunit gene (SCN1A) are to be causally related with several phenotypes of epilepsy, generalized epilepsy with febrile seizure plus (GEFS+), Dravet(More)
Brain hypoperfusion observed on single-photon emission computed tomography (SPECT) is a typical finding in the acute phase of human herpesvirus-6 (HHV-6) encephalopathy. However, from 2004 to 2010, we encountered three cases of HHV-6 encephalopathy in which hyperperfusion in the area of the brain lesion was observed on SPECT performed within 48 hours after(More)
