PURPOSE Interictal [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) demonstrates temporal hypometabolism in the epileptogenic zone of 60-90% of patients with temporal lobe epilepsy. The pathophysiology of this finding is still unknown. Several studies failed to show a correlation between hippocampal FDG-PET hypometabolism and neuronal cell(More)
Neuroimaging studies in major depressive disorder (MDD) have indicated dysregulation in a network involving prefrontal cortex, subgenual cingulate and the amygdalae, which is known to be modulated by serotonin. The serotonergic system is the principal target for pharmacological treatment in MDD and the functional variable serotonin promoter polymorphism(More)
Alterations of regional cerebral blood flow (rCBF) in prefrontal cortex and the anterior cingulate cortex are conspicuous imaging findings in patients with major depression (MD). While these rCBF changes have been suggested as functional disease markers, data in large patient samples examining treatment response prediction to antidepressant therapy are(More)
UNLABELLED Major depression (MD) is the most frequent psychiatric disorder with a predicted increase within the next decade. The understanding of the neurobiologic basis of its cause, antidepressive treatment effects, and identification of treatment outcome predictors is of crucial importance to warrant efficient medical care. The aim of our study was to(More)
