Women With Anorexia
The sense of taste is different in women with anorexia
The study also shows that there may be differences in the processing of the information related to the awareness of oneself in people who are recovering from the anorexia, compared to those that have not suffered the disease. The discovery may lead to a better understanding of the cause of this serious mental disorder.
In the study, led by Angela Wagner and Walter H. Kaye, midila brain activity of 32 women using resonance magnica functional imenes (fmri). The researchers examined the brain imenes of 16 women who are habn recovered from the anorexia, and 16 who were the subject of control. Measured reactions to the brain pleasant flavor (sucrose) and the neutral flavor (distilled water).The results of this study by fmri are the first test of that people with anorexia perceive the flavor of a different way to perceive healthy individuals.
The imenes showed that women who are habn recovered from the anorexia, tenn a response significantly less in the sula and brain regions related, in comparison with the response shown by the control group. These eas of the brain analyzed the taste and determine cu pleasant is. In addition, while the control group mostruna strong relationship between the activity of the sula and the assessment that hacn of flavor, this relationship was not in those habn recovered from the anorexia.
According the researchers, it is possible that individuals with anorexia have difficulty to recognize the flavor, or to experience the response pleasant associated with the food. Given that this region of the brain also contributes to regulate emotional, can the food the perceived as repugnant, instead of pleasant. This explain by qulas people anoricas do not fall into the temptation to eat foods that are irresistible for almost anyone, did not respond appropriately to the sensation of hunger and, ultimately, lose as much weight.

Often, begins in adolescence, but its harmful effects extend throughout life, and is nine times m common in women than in men. These caracterticas support the possibility that the causes residing in processes biolicos.
