Mood Disorders

Also known as Affective Disorders, the Mood Disorders are psychiatric conditions whose main symptoms involve a severe disturbance of one's mood.

Depressive Disorders are characterized by very low moods and a loss of pleasure and interest in life. These include Major Depressive Disorder, Dysthymia, Seasonal Affective Disorder, Postpartum Depression, Premenstrual Dysphoric Disorder (PMDD), and Minor Depression.

Bipolar Disorder involves mood episodes that can be either very low, like in Depression, or very high. During these 'high' episodes, called Mania, a person's mood can become abnormally elevated or irritable, and they will also tend to experience a lot more drive and energy than usual.
