Epileptiform discharges what are they
WebEpilepsy is one of the common encephalopathies caused by sudden abnormal discharges of neurons in the brain. About 30% of patients with epilepsy are insensitive and refractory to existing antiseizure medications. The sonic hedgehog signaling pathway is essential to the development and homeostasis of brain. Aberrant sonic hedgehog signaling is increased … WebOf note, this tracing also shows a BET -- a benign epileptiform transient of sleep. Despite the name, this is a normal finding in sleep and is discussed more in the normal variants section. In brief, though, BETs differ from actual epileptiform discharges in …
