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, allow down though monoaminergic antidepressants are generally used for first-line treatment, they do not exert their clinical benefit immedia! tely and for some people they do...If you want to get a full essay, order it on our website: OrderCustomPaper.com
