Postictal psychoses: in comparison with acute interictal psychoses.

The association between epilepsy and psychosis has attracted considerable attention since the 19th century. While modern research has made great efforts to elucidate the nature of the chronic and acute interictal psycho, observations on postictal psychotic states have been largely ignored. Such authors as Levin et Logsdail et a1.6 and Savard et al.7 are exceptions. They pointed out that postictal psychoses occurred after a lucid interval; postictal psychoses could not be explained simply as a sequel to the impaired consciousness precipitated by the preceding seizures. The present study aims to clarify the salient features of postictal psychoses by comparing postictal and interictal (or alternative) psychoses. sis2 4 8 9
