Severe myoclonic epilepsy of infancy: extended spectrum of GEFS+?
The family history of seizures in SMEI is in keeping with the spectrum of seizure phenotypes seen in generalized epilepsy with febrile seizures plus (GEFS+). Our findings suggest that SMEI is the most severe phenotype in the GEFS+ spectrum.
These findings, obtained by using laboratory assay, confirm the reduced risk of developing preeclampsia with tobacco exposure.
