Classmate 1 Response : Week 10 – Anorexia NervosaCarlson and Birkett state that hereditary factors play an important role in the development of anorexia nervosa. (2019, p 290). In addition, certain biological factors independent of heredity may also play a role in anorexia nervosa. (Carlson and Birkett, 2019, p 290).
Oppenheim also writes, “It turns out that eating disorders have a strong biological basis. Since genetics accounts for 50-80% of the risk of developing an eating disorder.” (2018, para 2).
Considering biological and hereditary factors would help explain why some people develop eating disorders while others do not, even if the living conditions are similar. (Oppenheim, 2018, para 2).
Studies have found that loss of gray and white matter within the brain is associated with people with anorexia. (Carlson and Birkett, 2019, p 290). Although gray matter volume is restored with weight gain, certain brain regions end up remaining small. (Oppenheim, 2018, para 8).
