There is evidence of serotonergic abnormalities in anorexics and bulimics. Can it be concluded that a dysfunction in the serotonin system underlies these eating disorders? Why or why not?
What will be an ideal response?
Although altered serotonergic levels have been observed in individuals with eating disorders, causal conclusions cannot be made. Changes in neurochemical function may be a cause and/or consequence of the psychological disorder. In order to conclude that altered serotonin function plays a causal role in eating disorders, changes in serotonergic function would need to be observed prior to the development of the eating disorder.
