The aim of this study was to describe the spectrum of psychotic disorders in an Argentine pop- ulation with refractory temporal lobe epilepsy (RTLE) and to determine the risk factors associated with psychotic disorders. Clinical variables of the epileptic syndrome were compared among a selected pop- ulation with RTLE with and without psychotic disorders (DSM-IV/Ictal Classification of psychoses). Logis- tic regression was performed. Sixty-three patients with psychotic disorders (Psychotic Group, PG) and 60 controls (Control Group, CG) were included. The most frequent psychotic disorders were brief psychotic episodes (35%) (DSM-IV) and interictal psychosis (50%) (Ictal Classification). Risk factors for psychotic dis- orders were bilateral hippocampal sclerosis, history of status epilepticus, and duration of epilepsy greater than 20 years.
