In their review of the schizophrenia-like psychoses of epilepsy, Slater et al. (1963) document the belief that although epilepsy (especially that of the temporal lobe) often precedes schizophrenia-like reactions, schizophrenia rarely precedes epilepsy. In their review of literature on the co-existence of schizophrenia and epilepsy, Slater et al. found but one reported case where temporal lobe epilepsy developed in a patient already psychotic. Their own series of 69 cases contained no instance of psychosis occurring prior to definite onset of epilepsy.
