TY  - JOUR
AB - Recent functional magnetic resonance (fMRI) imaging studies have revealed that subchronic medication with escitalopram leads to significantreduction in both amygdala and medial frontal gyrus reactivity during processing of emotional faces, suggesting that escitalopram may have adistinguishable modulatory effect on neural activation as compared with other serotonin-selective antidepressants. In this fMRI study we aimed toexplore whether short-term medication with escitalopram in healthy volunteers is associated with reduced neural response to emotional processing,and whether this effect is predicted by drug plasma concentration. The neural response to fearful and happy faces was measured before and on day7 of treatment with escitalopram (10mg) in 15 healthy volunteers and compared with those in a control unmedicated group (n=14). Significantlyreduced activation to fearful, but not to happy facial expressions was observed in the bilateral amygdala, cingulate and right medial frontal gyrusfollowing escitalopram medication. This effect was not correlated with plasma drug concentration. In accordance with previous data, we showed thatescitalopram exerts its rapid direct effect on emotional processing via attenuation of neural activation in pathways involving medial frontal gyrus andamygdala, an effect that seems to be distinguishable from that of other SSRIs.
