Serotonin may indirectly influence mood by altering emotional processing biases that are seen at both the cognitive/behavioral and neural level. [ 40 ] [ 39 ] Pharmacologically reducing serotonin synthesis, and pharmacologically enhancing synaptic serotonin can produce and attenuate negative affective biases, respectively.
Owing to the lack of a widely accepted comprehensive theory of the biology of mood disorders, there is no widely accepted theory of how these changes lead to the mood-elevating and anti-anxiety effects of SSRIs. Their effects on serotonin blood levels, which take weeks to take effect, appear to be largely responsible for their slow-to-appear ...
Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.

Selective serotonin reuptake inhibitors (SSRIs) selectively inhibit the reuptake of serotonin and are a widely used group of antidepressants. [31] With increased receptor selectivity compared to TCAs, undesired effects such as poor tolerability are avoided. [29] Serotonin is synthesized from an amino acid called L-tryptophan.
