The cause of serotonin toxicity or accumulation is an important factor in determining the course of treatment. Serotonin is catabolized by monoamine oxidase A in the presence of oxygen, so if care is taken to prevent an unsafe spike in body temperature or metabolic acidosis, oxygenation will assist in dispatching the excess serotonin. The same ...
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.
In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue.

Serotonin pathways are thought to modulate eating, both the amount as well as the motor processes associated with eating. The serotonergic projections into the hypothalamus are thought to be particularly relevant, and an increase in serotonergic signaling is thought to generally decrease food consumption (evidenced by fenfluramine , however ...
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [1] but not deeper investigation such as neuroimaging.
NHS figures show that the number of people in England taking antidepressants continues to rise, with 8.3m patients receiving them in 2021/22. No ‘clear evidence’ depression is caused by low ...
Serotonin Is Released Another part of this sexy equation is serotonin—a neurotransmitter and hormone, commonly referred to as the “happy chemical,” that plays a role in regulating mood.
First, serotonin system dysfunction cannot be the sole cause of depression, because not all patients treated with antidepressants show improvement, despite the fact that most patients still show a rapid increase in synaptic serotonin. Second, if significant mood improvements do occur, this is often not for at least two to four weeks.
