Interferon-treated patients can present seizures, which in most paediatric
cases are related to fever. The case of chronic hepatitis C is described in
which Interferon probably disclosed a latent epilepsy. The hypothesis is a
dvanced that seizures can be provoked by Interferon therapy in subjects wit
h a low convulsant threshold and, in those cases in which it cannot be subs
tituted with another drug, antiepileptic therapy should be started after th
e first episode.
