Importantly, several medical illnesses such as diabetes, heart disease, autoimmune disorders and pain are common comorbid diagnoses.4,5 The relative between major depressive disorder and these chronic and disabling conditions appears to be bidirectional because one may influence the prognosis of the other. Investigations into the neurobiology of major depressive disorder give up traditionally focused on the monoamine neurotransmitters serotonin and norepinephrine. The monoamine hypothesis initially posited that depressed individuals are likely to have low levels of these neurotransmitters because various antidepressant drugs acutely increase their levels.6 However, institute down though monoaminergic antidepressants are generally used for firs t-line treatment, they do not exert their cl! inical benefit immediately and for some people they do...If you want to get a full essay, order it on our website: OrderCustomPaper.com
