=== Personality traits ===
There are various childhood [[personality traits]] associated with the development of eating disorders, such as perfectionism and neuroticism.<ref name=":19" /><ref name=":24"/><ref name=":32">{{cite journal | vauthors = Pollack LO, Forbush KT | title = Why do eating disorders and obsessive-compulsive disorder co-occur? | journal = Eating Behaviors | volume = 14 | issue = 2 | pages = 211–215 | date = April 2013 | pmid = 23557823 | pmc = 3618658 | doi = 10.1016/j.eatbeh.2013.01.004}}</ref> These personality traits are found to link eating disorders and OCD.<ref name=":19" /><ref name=":24"/><ref name=":32" /> During adolescence these traits may become intensified due to a variety of physiological and cultural influences such as the hormonal changes associated with puberty, stress related to the approaching demands of maturity and socio-cultural influences and perceived expectations, especially in areas that concern body image. Eating disorders have been associated with a fragile sense of self and with disordered mentalization.<ref>{{cite book | vauthors = Skårderud F, Fonagy P | chapter = Eating Disorders | veditors = Bateman A, Fonagy P | title = Handbook of mentalizing in Mental Health Practice | publisher = American Psychiatric Publishing | location = Washington DC | date = 2012 | pages = 347–383}}</ref> Many personality traits have a genetic component and are highly heritable. Maladaptive levels of certain traits may be acquired as a result of anoxic or traumatic brain injury, neurodegenerative diseases such as [[Parkinson's disease]], [[neurotoxicity]] such as lead exposure, bacterial infection such as [[Lyme disease]] or parasitic infection such as [[Toxoplasma gondii]] as well as hormonal influences. While studies are still continuing via the use of various imaging techniques such as [[fMRI]]; these traits have been shown to originate in various regions of the brain<ref>{{cite journal | vauthors = Gardini S, Cloninger CR, Venneri A | title = Individual differences in personality traits reflect structural variance in specific brain regions | journal = Brain Research Bulletin | volume = 79 | issue = 5 | pages = 265–270 | date = June 2009 | pmid = 19480986 | doi = 10.1016/j.brainresbull.2009.03.005 | s2cid = 25490518}}</ref> such as the [[amygdala]]<ref>{{cite journal | vauthors = Marsh AA, Finger EC, Mitchell DG, Reid ME, Sims C, Kosson DS, Towbin KE, Leibenluft E, Pine DS, Blair RJ | title = Reduced amygdala response to fearful expressions in children and adolescents with callous-unemotional traits and disruptive behavior disorders | journal = The American Journal of Psychiatry | volume = 165 | issue = 6 | pages = 712–720 | date = June 2008 | pmid = 18281412 | doi = 10.1176/appi.ajp.2007.07071145 | s2cid = 6915571}}</ref><ref>{{cite journal | vauthors = Iidaka T, Matsumoto A, Ozaki N, Suzuki T, Iwata N, Yamamoto Y, Okada T, Sadato N | title = Volume of left amygdala subregion predicted temperamental trait of harm avoidance in female young subjects.
