Core Concepts and Mechanisms

The monoamine hypothesis suggests depression is caused by an excess of serotonin and norepinephrine.

Answer: False

Related Concepts:

  • What is the monoamine hypothesis of depression, and what are its limitations?: The monoamine hypothesis, originating in the 1950s-60s, posits that depression is caused by an imbalance, often a deficiency, of monoamine neurotransmitters like serotonin, norepinephrine, and dopamine. Its limitations include the delayed onset of action for monoaminergic antidepressants and the fact that many depressed individuals do not respond to them.
  • What alternative hypotheses have been proposed for antidepressant action?: Alternative hypotheses for antidepressant action have been proposed, focusing on factors such as glutamate, neurogenesis, epigenetics, cortisol hypersecretion, and inflammation, suggesting that depression and its treatment may involve more complex biological pathways than solely monoamine levels.
  • What alternative hypotheses have been proposed for antidepressant action?: Alternative hypotheses for antidepressant action have been proposed, focusing on factors such as glutamate, neurogenesis, epigenetics, cortisol hypersecretion, and inflammation, suggesting that depression and its treatment may involve more complex biological pathways than solely monoamine levels.

A 2022 umbrella review supported the serotonin theory of depression.

Answer: False

Related Concepts:

  • What did a major umbrella review conclude about the serotonin theory of depression?: A 2022 umbrella review by Joanna Moncrieff and colleagues concluded that the serotonin theory of depression is not supported by the available evidence, finding no association between serotonin levels or activity and depression, and thus questioning the basis for its widespread promotion.
