Abstract:
The pathophysiology of widespread interictal hypometabolism in
temporal lobe epilepsy is unknown but might reflect neuronal loss and
diaschisis. We found no significant correlation between any cortical
region's metabolism on preoperative [18F]fluorodeoxyglucose positron
emission tomography and neuronal density of resected hippocampi in 40
patients. We conclude that hippocampal neuronal loss and diaschisis
cannot account for the regional interictal hypometabolism of temporal
lobe epilepsy
