Long-term prognosis on recurrence of seizures among children with epilepsy after drug withdrawal-elimination.

The long-term prognosis of 110 children after withdrawal-elimination of the drugs on the basis of our rigid criteria was analyzed. The 12 cases (10.9%) of 110 patients experienced recurrences, which occurred between three months to three years after drug elimination, but there were no recurrences later than three years to 10 years after drug elimination. The asymmetry in the EEG during the first two to three years after drug elimination appeared in 6.4% and seizure discharge appeared in 17.1%. But no asymmetry nor seizure discharge was found in EEG later than three years after drug elimination.
