A 38-year-old man, possibly with frontal lobe epilepsy, developed postictal mania. The changes in psychiatric symptoms and laboratory examinations over time were investigated in two episodes of postictal mania, using long-term electroencephalography with closed circuit television (EEG/CCTV) monitoring, magnetoencephalography (MEG), and single-photon emission computed tomography (SPECT) to elucidate the underlying mechanism of postictal mania. According to the clinical symptoms, the postictal manic episodes of this case had four phases: a lucid interval, manic phase, hypomanic phase, and recovery phase. EEG showed forced normalization during the florid manic phase. The serial findings of EEG, MEG, and SPECT during the postictal manic episodes suggest that functional changes in bilateral frontal lobes, especially the right frontal lobe, right temporal lobe, and right paralimbic area, are crucial in the development of postictal mania, and that these functional changes are dynamic.
