Not really sure where this belongs, feel free to move it.
I (and I'm sure everyone who has ever turned on a television or browsed the internet) has seen countless articles on serotonin being THE neurotransmitter involved in depression. Statements like "xx works by increasing the levels of serotonin in the brain, the hormone that relieves depression" are incredibly twisted.
Sure, it is true that serotonin is released when a person is happy. However, this is the logical fallacy of many people: Serotonin released when a person is happy does NOT mean serotonin makes a person happy.
Contradictory to the public's "information", there are many reasons that show that 5-HT does NOT equal "happiness". Serotonin antagonists such as mirtazapine, the tricyclics, and antipsychotics like aripiprazole are classified as antidepressants, and they are effective. It is also worth noting that initial effects of SSRI's increase depressive and anxious thoughts and behaviors, and that many people find that the time that the therapeutic effects of SSRI's start to occur is also the theoretical time when 5-HT receptors would start to down regulate from increased serotonin.
So with all this put on the table, WHY is serotonin the neurotransmitter that is focused most on in antidepressant drugs and is for the most part still taught in many textbooks to be the "hormone/neurotransmitter that relieves depression"?
