The fight against neurodegenerative diseases is all the more effective the sooner the therapy begins. The problem is that the detection of these ailments, as a rule, occurs already at the stage of the manifestation of the first symptoms of the defeat of the nervous system. But according to Science Alert, thanks to scientists from the University of Carolina, the therapy and quality of life of patients with Parkinson's disease can significantly improve, because according to their studies, the first signs of the disease can be registered in the intestines long before the onset of symptoms.

The creation of a new theory is led by a scientific group headed by Boiling Lew. They managed to notice that patients who underwent a vagotomy procedure (excision of the vagus nerve) were 40% less likely to suffer from Parkinson's disease. Dr. Lew's group examined the data of the National Register of Diseases for the past 40 years. The data of 9430 people who underwent vagotomy and data on 377,200 patients who did not perform this operation were analyzed. In addition, the data on the mode of operation were studied separately: selective or complete vagotomy.

As it turned out, the risk of developing Parkinson's disease with selective vagotomy was 1.08%, and at a total of 0.78%. But the risk of developing the disease among those who did not undergo vagotomy was 1.15%. The fact is that the vagus nerve is one of the cranial nerves that regulate the functioning of the digestive tract. And experts have suggested that it can play a significant role in the development of the disease. Perhaps the disease begins in the intestine, where the proteins begin to "break down", and then the vagus nerve already transmits this error to the brain. Thus, if further research confirms this theory, it will be possible to develop a technique for the early diagnosis of Parkinson's disease in order to detect the disease before the onset of lesions of the nervous system.
