Benign familial neonatal epilepsy BFNE is a rare genetic epilepsy syndrome characterized by the occurrence of afebrile seizures in otherwise healthy newborns with onset in the first few days of life. Prevalence is currently unknown since this disorder is possibly overlooked. About families have been reported to date. Seizure onset is usually between the second and the eighth day of life, in otherwise healthy newborns.
Seizures are mostly focal involving alternatively both sides of the body and apnea is frequently associated. Seizures can be isolated or in clusters, are generally brief and last minutes. However, they can be very frequent, occurring up to 20 times a day, and may evolve into status epilepticus. During the interictal period, neonates are convulsiobs normal, although some degree of sedation can be seen in response to anti-epileptic medications.
Although onnatales patients do receive antiepileptic treatment in nonatalez neonatal period, seizures have been shown to remit spontaneously after the first months of life, and are usually not seen after the first year of life.
Subsequent psychomotor development is normal. Electroclinical events are suggestive of the disorder. Asymmetric tonic posturing associated with apnea and followed by focal or bilateral clonic jerking is the typical seizure type.
Etiology of convulsions in neonatal and infantile period.
In BFNE, neonates are neurologically normal and neurocognitive development is normal. Ictal electroencephalogram EEG may show focal interictal abnormalities, mainly over the central regions, but otherwise the EEG background is normal.
The diagnosis is confirmed by genetic testing. Differential diagnosis includes benign familial neonatal-infantile seizures and benign familial infantile epilepsy. Prenatal diagnosis is possible if the disease-causing mutation has already been identified in the family. Transmission is autosomal dominant with incomplete penetrance.

Rare cases are due to de novo mutations. The use of anticonvulsant therapy e. Usually, patients require treatment for the first months of life.
However, it is important for clinicians and family to be aware that some patients require treatment beyond 12 months of age. Seizures normally disappear during the first year of life and patients do not display any neurological sequelae.
Later seizures have been reported, including occasional febrile seizures and idiopathic epilepsy syndromes in childhood, in particular Rolandic epilepsy. Other search option s Alphabetical list.
