Step-by-step explanation:
Bipolar disorder and major depressive disorder are both mood disorders, but they have some key differences. Bipolar disorder is characterized by the presence of manic and depressive episodes. During manic episodes, individuals may experience elevated mood, increased energy, and impulsivity. Whereas, during depressive episodes, individuals may feel sad, hopeless, and have a lack of interest or pleasure in activities.
On the other hand, major depressive disorder primarily involves depressive episodes without manic or hypomanic episodes. It is characterized by persistent feelings of sadness, loss of interest, changes in appetite and sleep, difficulty concentrating, and thoughts of death or sui_cide.
While both disorders involve mood disturbances, bipolar disorder includes the presence of manic episodes, which major depressive disorder does not have. Additionally, the treatment approach for each disorder may differ, with bipolar disorder often requiring mood stabilizers to manage the mood shifts.
