Explain the biological explanations of one of more eating disorders.

Researchers have attempted to explain take dis molds through neurologic abnormalities and biochemical imbalances. The hypothalamus acts as a form of dominance throw out which sends messages to various separate of the brain affecting the behaviours that control eating. in that location are cardinal parts, the lateral hypothalamus (LH) and the ventromedial hypothalamus (VMH). The former supposedly produces aridness when activated whilst the latter depresses the appetite when it is activated. Keesey and Corbett (93) found that these two parts of the brain act as a back up thermostat. The LH is activated if the weight falls lower-rankinger than the fall dapple in order to produce hunger even if it weight continues to fall the VMH is activated. If the hypothalamus is not functioning adequately, this could provide an explanation for eating disorders. This malfunctioning of the hypothalamus may cause a indigenous business such as Amenorrhea which sometimes takes manoeuvre forrader weight loss callable to low endocrinal levels. The major problem with this theory however is that there is no determinate evidence from post-mortems that anorexia and bulimia are caused by neurological scathe as they have not found some(prenominal) constipation to the hypothalamus. Research has been carried out more recently analyse the effectuate of some neurotransmitters such as norepinephrine, dopamine and serotonin due to evidence that sufferers of anorexia and bulimia have abnormalities in their levels of neurotransmitters.

Jimerson et al (97) compared the serotonin function in patients with bulimia with a control root of healthy part! icipants and found significant differences. They concluded that afflicted serotonin responsiveness may provoke the onset of bulimia and hold open the disorder. Binge eating is linked with low levels of serotonin then Walsh et al (97) developed a serotonin-active antidepressant which has proven to be the most effective biological interference for bulimia as it decreases binge eating.
