Abstract
Effect of Escitalopram on Attentional Bias in Panic Disorder an Event-Related Potential Study
Highlights
Panic disorder (PD) is a type of anxiety disorder and characterized by the repeated occurrence of unexpected panic attacks, during which the individual experiences a strong fear with anticipation of death
Individuals with PD pay more attention to threatening facial expressions, i.e., individuals with PD show a greater bias towards negative stimuli and event-related potentials (ERPs) offers objective evidence that treatment with Escitalopram leads to the improvement of attentional bias
In the present study, using an ERP dot-probe task of facial expression, we investigated the effect of treatment with Escitalopram on attentional bias in PD
Summary
Panic disorder (PD) is a type of anxiety disorder and characterized by the repeated occurrence of unexpected panic attacks, during which the individual experiences a strong fear with anticipation of death. Individuals who are suffering from PD are often accompanied by somatic symptoms such as palpitations, dyspnoea or faintness. Those suffering from PD have persistent anticipatory fear of recurrent attacks and feel anxious even while they have no occurrence of panic attacks for a certain period. Cognitive models propose that biased information processing plays an important role in the etiology and maintenance of the disorder [1]. As opposed to a more general bias towards threatening information, studies showed that individuals with PD show a greater bias mainly towards disorder-relevant stimuli [2]
