PG - 2137-2145 LID - 10.1007/s00330-016-4531-z [doi] AB - OBJECTIVES: Our aim was to investigate regional difference in brain activities in response to antiepileptic drug (AED) medications in benign epilepsy with central-temporal spikes (BECTS) using resting-state functional magnetic resonance imaging (fMRI). METHODS: Fifty-seven patients with BECTS underwent resting-state fMRI scans after receiving either valproic acid (VPA) (n = 15), levetiracetam (LEV) (n = 21), or no medication (n = 21). fMRI regional homogeneity (ReHo) parameter among the three groups of patients were compared and were correlated with total doses of AED in the two medicated groups. RESULTS: Compared with patients on no-medication, patients receiving either VPA or LEV showed decreased ReHo in the central-temporal region, frontal cortex, and thalamus. In particular, the VPA group showed greater ReHo decrease in the thalamus and milder in cortices and caudate heads compared with the LEV group. In addition, the VPA group demonstrated a negative correlation between ReHo values in the central-temporal region and medication dose. CONCLUSION: Both VPA and LEV inhibit resting-state neural activity in the central-temporal region, which is the main epileptogenic focus of BECTS. VPA reduced brain activity in the cortical epileptogenic regions and thalamus evenly, whereas LEV reduced brain activity predominantly in the cortices. Interestingly, VPA showed a cumulative effect on inhibiting brain activity in the epileptogenic regions in BECTS. KEY POINTS: * Regional differences in brain activity in response to different AEDs in BECTS. * AEDs inhibit resting-state neural activity in epileptogenic and subcortical regions in BECTS. * Valproic acid effect on the cortical epileptogenic regions and thalamus evenly. * Levetiracetam effect seen predominantly in cortices. * Valproic acid has a cumulative effect on inhibiting brain activity in epileptogenic regions.
