Postictal mania following primary generalized seizures.

A 29 year old male with primary generalized seizures for 13 years stopped his anticonvulsants leading to an increase in seizure frequency. Five months later he developed a severe manic episode postictally which responded well to a combination of neuroleptics and anticonvulsants. Postictal psychoses usually follow complex partial seizures. Manic episodes are uncommon. This case had some similarities with other cases of postictal psychoses reported previously. It underlines the need for further investigation of several facets of this complex relationship between mood disorders and epilepsy.
