Abstract：
INTRODUCTION:The cognitive processing in patients with functional dyspepsia (FD) has not been well established. Decision-making is an important component of cognitive function. Most brain regions involved in decision-making are abnormal in FD patients. This study aimed to investigate the decision-making under ambiguity and risk in FD patients. METHODS:We recruited 40 FD patients meeting Rome III criteria and 40 healthy controls (HCs) matched for age, sex, marital status, and education level. The Hamilton Anxiety Scale (HAMA) and the 17-item Hamilton Depression Scale (HAMD-17) were used to evaluate their anxiety and depression emotions. The Iowa Gambling Task (IGT) and Game of Dice Task (GDT) were used to evaluate decision-making under ambiguity and risk, respectively. Helicobacter pylori status, disease duration, dyspeptic symptom score, and the Nepean Dyspepsia Life Quality Index (NDLQI) were obtained from all patients. RESULTS:In IGT, FD patients had a lower total net score, chose more adverse choices, and showed a slower response to change their behavior than HCs. However, there was no significant difference in the net score of the first 2 blocks between the two groups. In GDT, FD patients had a lower total net score, higher risk score, and lower use of negative feedback than HCs. In addition, FD patients showed better GDT performance than those without early satiation. CONCLUSIONS:FD patients showed impaired decision-making under risk. The deficiency might be related to dyspeptic symptoms of FD patients.
