As it helps regulate your mood, serotonin is often called the body's natural "feel-good" chemical. Serotonin's influence on mood makes it one of several brain chemicals that are integral to your overall sense of well-being. Serotonin is key to our feelings of happiness and very important for our emotions because it helps defend against both anxiety and depression. Many of the current biochemical theories of depression focus on the biogenic amines, which are a group of chemical compounds important in neurotransmission—most importantly norepinephrine, serotonin and, to a lesser extent, dopamine, acetylcholine and RationaleRapid tryptophan depletion (RTD) has been used to study central serotonin function and may therefore be useful in understanding co-morbid alcohol dependence (AD) and major depressive disorder (MDD).ObjectivesTo examine (1) the effect of RTD on mood and urge to drink among patients with AD and MDD and (2) the association of RTD effects with alleles of a functional polymorphism in the 14 Aug 2019 The effects of alcohol use, such as liver damage, are well known.

Several types of these receptors exist, including the 5-HT1A, 5-HT1B, 5-HT2, and 5-HT3 receptors (see table). 2012-08-01 · Serotonin and dopamine may play a role in alcohol cue-induced craving. Acute combined tryptophan (Trp), tyrosine (Tyr), and phenylalanine (Phe) depletion (CMD) in the diet attenuates the synthesis of serotonin and dopamine in the human brain. However, no study of the effects of acute CMD has been previously conducted.

The hypothesis that a serotonin deficit is associated with negative emotions, such as anxiety or depression, is supported by studies in which serotonin depletion induced negative mood states among patients with obsessive-compulsive disorder and in a subgroup of patients with major depression who previously responded to serotonin reuptake inhibition (Barr et al., 1994; Delgado et al., 1990).

Acute combined tryptophan (Trp), tyrosine (Tyr), and phenylalanine (Phe) depletion (CMD) in the diet attenuates the synthesis of serotonin and dopamine in the human brain.
