Which of the following are major types of mood disorders?

The selection highlighting Depression, Bipolar Disorder, Manic/Depressive Episodes, and Anxiety Disorders encompasses the correct identification of major types of mood disorders.

Depression is characterized by persistent feelings of sadness and loss of interest, which can significantly affect daily functioning. Bipolar Disorder involves experiencing extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). The term "Manic/Depressive Episode" refers to the episodes experienced in bipolar disorder where an individual may alternate between manic behavior and depressive states. While anxiety disorders are not classified solely as mood disorders, they can be closely related and often co-occur with mood disorders, impacting the overall emotional state of individuals.

In contrast to the other options, they include terms or conditions that do not represent established mood disorders or are misclassified as such. Recognizing the specific types of mood disorders helps in understanding their symptoms and effective treatment options.
