SUMMARY 123 I‐ZMP‐SPECT scans at the interictal stages in 13 epileptic patients with normal X‐ray CT findings were reexamined at intervals of 1.9 ± 0.8 years. Interictal scalp EEGs were recorded a few hours after each SPECT scan. All of the SPECT abnormalities indicated focal hypo fixation images of 123 I‐IMP, i.e. zones of a decreased rCBF reflecting a functional inactivation. Among 11 patients with the SPECT abnormalities in the first SPECTs, eight cases had the complete or partial regional reproduction of the abnormalities in the second SPECTs. As changes in the SPECT findings, an alteration from the abnormal SPECT images to
