What Neurotransmitter Seems To Be Involved in Both Eating Disorders and Depression? This article examines the role of the Dopaminergic neurotransmitter in the pathophysiology of anorexia nervosa. Dopamine has distinct functions that are linked to feeding, reward processing, learning, and cognitive functions. It is unclear if these functions are involved in the pathophysiology of anorexia nervosa. But it’s important to understand how these neurotransmitters work in the brain and how they interact with eating disorders. Dopaminergic neurotransmitter Dopamine is a neurotransmitter involved in the regulation of the reward system. It is linked to rewarding behaviors and drugs of abuse. However, it is also involved in other functions, including sensory processing, movement, and memory. Eating disorders can be caused by low levels of this neurotransmitter. Moreover, it may be downregulated in patients with BN. Hence, more research is needed to understand how this neurotransmitter works.
One study found that this neurotransmitter may be involved in eating disorders and depression. A study conducted in eight obese adults who did not suffer from any eating disorder assessed brain activity in response to oral food stimuli. Dopaminergic activity in the cone area was found to increase significantly in response to the food stimuli. Moreover, the response was positively associated with the occurrence of binge eating symptoms.

Five of the nine studies conducted on patients with eating disorders showed an unchanged dopaminergic state. Two case-control studies found that the presence of dopamine receptors was related to decreased binge eating. Another animal study showed no effect of either dopamine receptor agonist or antagonist on binge eating behaviors. This study supports the concept that dopamine is involved in eating disorders and depression.
Although many of these findings were inconsistent, some hypotheses based on research on binge eating and depression may be able to reconcile them. One possible explanation is that both hypodopaminergic and hyperdopaminergic states coexist in binge eating. This theory also fits with other research on other diseases. Therefore, it is important to understand how these two neurotransmitters relate to eating disorders and depression. Serotonin In the human body, serotonin regulates mood and appetite. It has a role in regulating sleep and arousal, as well as appetite. Studies have linked decreased serotonin levels with eating disorders and depression, as do abnormally high levels of serotonin with OCD. This is just one example of the many roles serotonin plays in the human body.
The two neurotransmitters dopamine and serotonin are linked to both the underlying mechanisms of eating and mood regulation. The brains of anorexics produce more dopamine, which affects reward and reinforcement. In contrast, the brains of obese women show abnormally low levels of serotonin, which is closely linked to mood and impulse control. This suggests that the brains of anorexics have high serotonin levels, and this may be a factor in the development of anorexia. What Neurotransmitter Seems To Be Involved in Both Eating Disorders and Depression? Can We Really Give An Answer To This? While older studies have questioned whether serotonin plays a role in depression, recent research claims it is involved. A 2016 study on mice that lack serotonin autoreceptors showed that the mice with increased serotonin levels exhibited less anxiety and depression-related behaviors than those with normal serotonin levels. Blood serotonin levels have a normal range of 100 to 183 nanograms per milliliter, though this range may vary depending on the sample and measurement method.
During recovery from anorexia and bulimia, brain activity related to serotonin levels is altered. This increased activity is strongly associated with a specific receptor that controls serotonin and is associated with harmful behaviors like harm avoidance. Researchers at McGill University have studied serotonin levels in recovering anorexic and bulimic patients to determine whether they are involved in eating disorders.
