Comparison of EEG, MRI and PET in reading epilepsy: a case report.
The pathophysiological and neuroanatomical bases of reading epilepsy (RE) are unclear. We performed video-EEG, high quality MRI and [11C]diprenorphine PET in a patient with RE to detect structural and functional abnormalities. EEG showed multifocal seizure onset bilaterally in temporal and fronto-central regions. MRI was normal, whereas [11C]diprenorphine PET revealed peri-ictal opioid binding decreases in both temporal lobes and the left frontal lobe. These findings confirm that RE is due to abnormal activity in the network subserving reading.
