My chapter is about Since 1970, psychopharmacotherapy has become more popular as the pharmaceutical industry has started to develop and produce more medicines for psychological treatments. In 2005, antidepressants were the most prescribed drug in the US causing quite a debate among psychiatrists and researchers alike. Some argue that it is encouraging to see the increasing number of people seeking help for depression while some critique the effectiveness of these antidepressant medications. As a biochemistry major, I am really curious about the mechanisms of the drug on our nervous systems as well as the side effects. Antidepressants have been reported to cause several adverse effects, ranging from headaches or nausea to increasing behavior and thoughts or psychological withdrawal symptom. The interesting thing I found about antidepressant is that the fake happiness it has created. Even though the medicine tries to alleviate the unhappiness for the patients, it doesn't solve the real problems they are facing. The patients will have to reply much on antidepressant and do not try to fix the problems themselves.
