Which neurotransmitter is linked to mood disorders like depression?

Monoamine neurotransmitters, such as dopamine, norepinephrine or serotonin are the most important neurotransmitters in pathophysiology of mood disorders and in mechanisms of action of antidepressants. Catecholamines (dopamine, norepinephrine and epinephrine) are synthesized from tyrosine.

Which neurotransmitter is associated with depression and mania?

Noradrenaline and serotonin have been consistently linked to psychiatric mood disorders such as depression and bipolar disorder. Nerve pathways within areas of the brain that regulate pleasure and emotional reward are regulated by dopamine.

What chemical is released during depression?

Low dopamine levels make people and animal models less likely to work toward achieving a goal. People with clinical depression often have increased levels of monoamine oxidase A (MAO-A), an enzyme that breaks down key neurotransmitters, resulting in very low levels of serotonin, dopamine and norepinephrine.
