Background and objectives: Irritable bowel syndrome (IBS) does not only have a complex pathophysiological evolution with central and peripheral mechanisms. This study aimed to monitor the neuropsychiatric part of IBS and its management, following the quality of life of patients with IBS. Materials and Methods: Participants numbering 145 were investigated in this study for 6 months and were divided into four groups, namely the control group with a symptomatic period of less than 6 months (n = 34), the group with irritable bowel syndrome (IBS; n = 58), IBS and neuropsychiatric treatment (n = 32), and IBS with probiotic treatment (n = 22). Clinical and paraclinical analyses as well as quality of life were monitored by domestic and international psychological questionnaires. Results: It was observed that, in patients with pro-longed symptoms, neuropsychiatric impairment occurred more frequently, and both clinical and paraclinical analyses improved significantly (p < 0.05) more so in those with complex allopathic treatment and in those with probiotic treatment. There were no significant differences between the two research groups. Conclusions: It has been shown that the neuropsychological component of IBS plays an important role in its treatment, and modern probation therapy can achieve similar results to those of neuropsychiatry. This also requires further studies to ensure the best combination in the approach to IBS.
