Mood disorders are a category of illnesses that describe a serious change in mood. Illnesses categorized as mood disorders include: depression, bipolar disorder, and seasonal affective disorder (SAD). About 20% of the US population reports at least one depressive symptom in a given month.
Mood disorders are highly treatable with steps such as medication, psychotherapy (talk therapy), and lifestyle changes. Many people find that after treatment, their lives are completely normal and they are happy again.
