Study Notes
Antidepressants and Mood Stabilizers

- Bipolar Disorder: A heritable disorder with contributions from genetic factors, dysfunctions in the brain, and imbalance of neurotransmitters.
Neuroanatomy and Neurotransmitters
- Neural Networks: Depression occurs from a deficiency of one or all three monoamine transmitters (5HT, NE, and DA), while mania occurs from an excess of these neurotransmitters.
- Monoamine Hypothesis: Depression is caused by a deficiency of neurotransmitters, while mania is caused by an excess.
SSRIs
- First-Line Treatment: SSRIs are the first-line treatment for depression.
- Mechanism of Action: SSRIs target 5HT to inhibit its reuptake.
- Side Effects: Diarrhea, headache, weight gain, and sexual side effects.
-

- Hypomanic: not of sufficient duration or severity to cause significant functional impairment, psychosis, or hospitalization
- Anger and irritability are common
- Clients often enjoy the elevation of mood and are reluctant to report these symptoms, making bipolar more difficult to diagnose if the client presents in the depression phase
