Abstract:
Converging evidence from investigations of the peripheral and central aspects of bidirectional brain-gut interactions is beginning to shape a pathophysiological model of irritable bowel syndrome (IBS) and related functional gastrointestinal (GI) disorders. This neurobiological model includes alterations in autonomic, neuroendocrine, and pain modulatory mechanisms. The frequent association of IBS and other functional GI disorders with co-morbid affective disorders and temporal association of symptom exacerbation with psychosocial or physical stressors are consistent with alterations in the neurobiological mechanisms underlying the central stress response. Renewed interest in drug development for IBS has resulted in development of instruments for the better assessment of the impact of global symptoms on quality of life and in the development of candidate compounds undergoing clinical evaluation.
