However, several obstacles need to be overcome to progress from successful preclinical studies in animal models to ENS stem cell therapies in the clinic. Neurogastroenterology Diagnostic Centre specialises in the diagnosis and evaluation of abnormal brain-gut functions, disorders of gut function, and helping to plan appropriate treatments with . In congenital megacolon (Hirschsprung disease), portions of the colon are aganglionic, and sustained contraction of a variable length of the preceding colon produces enlargement of the colon. The microbiota communicates with the brain through the microbiota-gut-brain axis in a bidirectional way that involves the autonomic nervous system. Symptomatic treatment for nausea may be adequate if gastric emptying is normal. In longstanding diabetes, degeneration and reduction in the number of myenteric neurons can lead to gastroparesis.

Adult enteric nervous system in health is maintained by a dynamic balance between neuronal apoptosis and neurogenesis. An experimental study has found reduced lactobacillus and increased circulating kynurenine levels as the most prominent changes in chronically stressed mice (38). The results, along with gastrointestinal symptoms, which can manifest years before the diagnosis of Parkinson disease, provide preliminary evidence that the disease may start in the gut.

Further data suggest that glial cell-line derived neurotrophic factor may play a protective role in the gut throughout life, and that dysregulation of neurotrophic factor support could contribute to neuronal ageing in the gut (26). The hypothesis that alpha-synuclein pathology could spread from the gut to brain via the vagus nerve was tested by assessing alpha-synucleinopathy in the brain in a novel gut-to-brain alpha-synuclein transmission mouse model, and the findings were as follows (25): Gut-to-brain propagation of pathologic alpha-synuclein via the vagus nerve causes Parkinson disease. It has successfully completed clinical trials and is approved by the European Medicines Agency. It may occur during sneezing and coughing or during sleep.

Microbes living in the gut may remotely influence the activity of cells in the brain that are involved in controlling inflammation and neurodegeneration. An impairment of this balance may result in obesity or cachexia. There is often a fine dividing line between the constipation and fecal incontinence in patients with spinal cord injury; with any management intended to ameliorate, one risks precipitating the other. The term "enteric neuropathies" is used for various conditions affecting motor function of the human gastrointestinal tract. Intestinal motor inhibition induced by surgery involves the release of corticotrophic-releasing hormone from the brain.
