Monoamine theory of mood

The monoamine theory of mood suggests that imbalances in neurotransmitters such as serotonin, dopamine, and norepinephrine contribute to mood disorders like depression. It proposes that increasing levels of these neurotransmitters can alleviate depressive symptoms, leading to the development of medications like SSRIs and SNRIs. However, this theory is not a complete explanation for all mood disorders and other factors may also play a role.
