Официальное название
Evaluation of Brain Connectivity Function in Predicting Therapeutic Effects in Patients With Refractory Constipation: a Multicenter, Prospective, Cohort Study
Обзор
The goal of this observational study is to identify the characteristics of brain functional connectivity in refractory constipation and fluoxetine-sensitive patients. The main questions it aims to answer are: * Investigating the alterations in brain functional connectivity in patients with refractory constipation and fluoxetine-sensitive patients * Assessing the predictive value of brain functional connectivity regarding the efficacy of fluoxetine and standard protocol treatments for constipation. Participants will receive: * Standard physiological and psychological assessments of constipation * BOLD-fMRI tests * Standard protocol and fluoxetine treatment If there is a comparison group: Researchers will compare: Refractory group/Fluoxetine sensitive group to see the specific brain alterations.
