Inter-ictal psychosis: who's at risk?
How distinct is inter-ictal psychosis from schizophrenic psychosis? A Japanese study of 285 adults with epilepsy and interictal psychosis showed psychosis beginning a mean of 14 years after epilepsy onset—earlier in those with generalised epilepsy, those with a psychosis family history, and those without learning difficulties.
