Benign infantile epilepsy (BIE), also known as benign infantile seizures (BIS), is an epilepsy syndrome of which several forms have been described. The International League Against Epilepsy (ILAE) classify two main forms of the syndrome though several other forms have been described in the academic literature. Affected children, who have no other health or developmental problems, develop seizures during infancy. These seizures have focal origin within the brain but may then spread to become generalized seizures. The seizures may occur several times a day, often grouped in clusters over one to three days followed by a gap of one to three months. Treatment with anticonvulsant drugs is not necessary but they are often prescribed and are effective at controlling the seizures. Sodium channel blockers in particular have been shown to be effective for benign infantile epilepsy. Levitiracetam, otherwise known as Keppra, has been associated with higher rates of seizure freedom than other forms of anti-epileptics.
