[Epilepsy and psychoses (from the viewpoint of a neurosurgical service)].

The experience of a neurosurgical unit devoted to the surgical therapy of the epilepsies is only based on very peculiar patients. However, relationship between a given epilepsy and associated psychiatric disorders are more easily understood because of more extensive explorations. Bilateral temporal epilepsies involving the limbic system on the one hand, bilateral frontal epilepsies on the other one, and P.M. status which may be paralleled, make these patients more susceptible to acute mental confusions, to acute thymic disorders, to delirious attacks. Direct relations between chronic psychosis and severe epilepsies are much more uncertain.
