Functional esophageal disorders are a class of gastrointestinal
disorders where no organic abnormality explaining the symptoms can
be identified. This disconnect between symptom perception and
physiological abnormalities results in adverse disease outcomes.
Given the impact of psychological processes on the gastrointestinal
tract through the brain-gut axis, research has shifted towards
identifying their potential role in modulating gastrointestinal symptom
perception. Esophageal hypervigilance, defined as increased
attention to esophageal stimuli, is proposed as a key driver of
esophageal symptom generation. However, research to date is
cross-sectional and based on data from self-report measures,
preventing directional, causal, or mechanistic conclusions. Thus,
there is a need for paradigms manipulating and quantifying attention
to esophageal sensations to increase our understanding of
esophageal hypervigilance. My interdisciplinary translational proposal
aims to (1) quantify hypervigilance towards esophageal stimuli and
its impact on intensity perception using novel paradigms, (2) identify
the underlying mechanisms using innovative analysis techniques,
and (3) make an early effort to translate these findings to functional
esophageal disorder patients. This will inform our fundamental
understanding of esophageal hypervigilance as well as identify a
target for novel psychological treatments in this notoriously difficult to
treat patient population
