Scientists from the University of Colorado (USA) have been researching the brain of bulimic women in an attempt to find out which nervous mechanisms are associated with this disorder of nutrition.
Bulimia is a serious nutritional disorder characterized by overdose attacks and then attempts to compensate for the damage caused by these attacks.
To avoid overweight, bulimic patients after overeating attempt to artificially cause vomiting, take diuretics and laxatives, and exhaust themselves with physical exercises.
Despite the relative prevalence of this disorder, scientists still do not fully imagine what is going on in the brain in the development of bulimia and what nervous processes and mechanisms affect the nutritional disorder.
Bulimia violates the system of encouragement in the brain
In a study published in the journal Biological Psychiatry, scientists have studied the activity of the dopamine system of stimulating the brain both in women who are suffering from bulimia, and in completely healthy.
Dopamine is one of the most important neurotransmitters in the brain and is involved in the regulation of behavior in the learning and motivation processes.
Scientists have found that women with bulimia have a weakened nerve response in those areas of the brain that are part of the incentive/reward system. And this answer was related to the frequency of overeating.
Thus, attacks of binge eating and further purification of the body can cause a weakening of the brain's reaction and initiate further changes and disorders in the function of some parts of the brain.
Prospects for treatment of bulimia
This discovery is important for several reasons. First, the study revealed the important role of the incentive system and the dopamine associated with it.
Secondly, the behavior characteristic of bulimia directly affects the brain system of encouragement, and it remains unknown whether data of brain functions return to normal after recovery.
Third, neurotransmitter dopamine may become a specific target in the treatment of bulimia with the help of special medications.
This study is the first one to suggest that the dopamine-induced brain stimulation system that regulates our food search behavior also plays an important role in the development of bulimia.
In women with bulimia, there was a significant decrease in the activity of the system of encouragement, and the more frequent were the attacks of gnarly and purification of the body, the less active became this area.
Thus, the study showed that the nutritional disorder directly affects the function of the brain. At the same time, due to this research, it became possible to invent new drugs for the treatment of bulimia, affecting certain brain structures.
