Overview
Variations in mood are normal. Mood can fluctuate from day to day and very few people will be the same on a day-to-day basis. Mood disorders (as defined by the pattern of mood episodes) happen when the patient’s mood becomes uncontrollable and causes impairment in daily life. They include major depressive disorder (unipolar depression, MDD), bipolar 1 disoder (bipolar depression), bipolar 2 disorder, cyclothymia, persistent depressive disorder (formerly dysthymia), among others. Some mood disorders can present with psychotic features (delusions, hallucinations)

- Why do mood disorders seem to affect women more than men?
- Cultural bias
- In most cultures women tend to be more open about their feelings
- Clinicians tend to be more attentive to feelings in women than in men
- Men are more likely to complain about things that surround their mood (”I can’t sleep at night”) rather than the mood itself (“I’m feeling down”)
- Mood disorders
- Major Depressive Disorder (Unipolar Depression)
- Bipolar I Disorder (Bipolar Depression)
- Bipolar II Disorder
- Persistent Depressive Disorder (PDD)
- Cyclothymia
- Premenstrual Dysphoric Disorder
- Puerperal Depression
- Depressive disorder due to medical condition
