Epilepsy, Pyridoxine-dependent; Epd

Description

Pyridoxine-dependent epilepsy, characterized by a combination of various seizure types, usually occurs in the first hours of life and is unresponsive to standard anticonvulsants, responding only to immediate administration of pyridoxine hydrochloride. The dependence is permanent, and the interruption of daily pyridoxine supplementation leads to the recurrence of seizures. Some patients show developmental delay. The prevalence is estimated at 1 in 400,000 to 700,000 (Bennett et al., 2005).
