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.
Overdose is usually treated symptomatically, especially in the case of serotonin syndrome, which requires treatment with cyproheptadine and temperature control based on the progression of the serotonin toxicity. [86] Patients are often monitored for vitals and airways cleared to ensure that they are receiving adequate levels of oxygen.
The serotonin created by the brain comprises around 10% of total body serotonin. The majority (80-90%) is found in the gastrointestinal (GI) tract. [15] [16] It travels around the brain along the medial forebrain bundle and acts on serotonin receptors. In the peripheral nervous system (such as in the gut wall) serotonin regulates vascular tone.
This was especially evident in a region of the brain stem associated with stress and anxiety. While serotonin may boost positive feelings, certain subsets of serotonin neurons can trigger anxiety ...
Serotonin is a neurotransmitter responsible for regulating important things like your mood, ability to concentrate, memory, ability to relax, appetite and ability to sleep.
The pharmacology of antidepressants is not entirely clear.. The earliest and probably most widely accepted scientific theory of antidepressant action is the monoamine hypothesis (which can be traced back to the 1950s), which states that depression is due to an imbalance (most often a deficiency) of the monoamine neurotransmitters (namely serotonin, norepinephrine and dopamine). [1]
Results showed their review of research on serotonin — the “happy hormone” — revealed “no convincing evidence that depression is associated with, or caused by, lower serotonin ...
Serotonin–norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine (Effexor), its active metabolite desvenlafaxine (Pristiq), and duloxetine (Cymbalta) prevent the reuptake of both serotonin and norepinephrine, however their efficacy appears to be only marginally greater than the SSRIs.
