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.
Which neurotransmitter is linked to mood disorders like depression?

Basic and clinical studies demonstrate that depression is associated with reduced size of brain regions that regulate mood and cognition, including the prefrontal cortex and the hippocampus, and decreased neuronal synapses in these areas.
