• Delusions and hallucinations are core symptoms of psychoses. The prevalence of psychoses in people with epilepsy is higher than in the general population. Links between psychoses and epilepsy have been observed since ancient times. Today, we are aware that not only epilepsy-related vulnerability factors but also individual-related (general) vulnerability factors make people with epilepsy more prone to psychoses. Bidirectional relationships between epilepsy and psychoses in their genesis are also recognized. Chronological relationships between the onset of the seizure and of the psychoses themselves are a feature unique to psychoses in epilepsy, which are classified as ictal, post-ictal, and inter-ictal accordingly. In this chapter, we have described delusions and hallucinations in people with epilepsy within the three subclassifications, since the manifestations are rather different among the three groups. We have summarized their treatment and prognosis, which again differ between the three types of epilepsy psychoses. We have then presented newer concepts on the genesis of these symptoms. Many characteristics are common between ictal (particularly during seizure status) and post-ictal phenomena; thus, there may be a practical value to have them unified and classed as peri-ictal phenomena. We have also reviewed accumulating evidence illustrating characteristics common between “epileptic” and “functional” psychoses. This highlights the importance of individual-related (general) vulnerability factors for the genesis of delusions and hallucinations in people with epilepsy.
