**Neurotransmitters and Depression**

A lack of these monoamines has been linked to depression. Depression is often treated with drugs that prolong the effect of these neurotransmitters either by preventing the re-uptake of the neurotransmitter or by inhibiting the enzyme that breaks down these neurotransmitters.

**Which of the following statements about neurotransmitters are true?** The table lists the classifications of three antidepressants.

| **Classification** | **Antidepressant** |
|---------------------|----------------------|
| selective serotonin re-uptake inhibitor (SSRI) | fluoxetine |
| monoamine oxidase (MAO) inhibitor | phenelzine |
| tricyclic antidepressant | amitriptyline |

**Check all that apply.**

- [ ] MAO inhibitors are examples of monoamine antagonists.
- [ ] Fluoxetine inhibits the enzyme that breaks down monoamines.
- [ ] Dopamine plays a role in feelings of pleasure and pain.
- [ ] A deficiency of serotonin, norepinephrine, and dopamine is associated with depression.
- [ ] Some drug addictions are the result of dopamine antagonists.
- [ ] Amitriptyline and fluoxetine both prevent the re-uptake of serotonin and norepinephrine.
- [ ] Depression may be treated with monoamine antagonists.

Serotonin, norepinephrine, and dopamine are a group of neurotransmitters collectively called monoamines. A lack of these monoamines has been linked to depression. Depression is treated with drugs that prolong the effect of these neurotransmitters either by preventing the re-uptake of the neurotransmitters, or by inhibiting the enzyme that breaks down these neurotransmitters.
