Neurocognitive performances were evaluated in 9 children with differen
t types of epilepsy prior to and at least 6 months after discontinuati
on of phenobarbital. The patients treated with phenobarbital monothera
py were seizure free for at least 2 years, without electro-encephalogr
aphic anomalies for at least 1 year, Results indicated that phenobarbi
tal at low therapeutic doses causes attentional and memory deficits, r
eversible after therapy discontinuation. Further research utilizing th
e same design is needed on larger samples in order to confirm our resu
lts.
