Unipolar vs. Bipolar Depression
The term unipolar depression is used to distinguish major depressive disorder from bipolar disorder, which is characterized by alternating periods of mania and depression. Sometimes bipolar disorder is misdiagnosed as unipolar depression. In these cases, treatment is not successful, as treatment for the two disorders differs. Unipolar depression has distinct differences from bipolar disorder, including lack of manic/hypomanic episodes; however, depression is also a symptom of bipolar disorder. It’s important that if you are having signs of depression, you receive a proper diagnosis from a medical professional, who will determine if you are experiencing unipolar depression or bipolar depression.
Characteristics and Symptoms of Unipolar Depression
Experiencing unipolar depression, or major depressive disorder, is different from feeling sad and down from time to time. Unipolar depression is characterized by feelings of depression that are persistent, intense, and that make it challenging for you to function normally or relate to others. Some of the main characteristics of unipolar depression include:
Feeling sad most days or having a chronic low mood Not enjoying activities that used to bring you pleasure Finding it difficult to experience joy or happiness Feeling emotionally numb Having trouble concentrating Lack of energy Noticeable changes in hunger Trouble sleeping Feeling agitated Having trouble completing tasks Feeling like you don’t matter Feeling guilty Experiencing thoughts of suicide or self-harm
Diagnosis of Unipolar Depression
In order to receive a diagnosis of unipolar depression, you will need to be evaluated by a doctor or psychiatrist. Evaluations for depression often include a physical exam, a medical and family history questionnaire, and bloodwork to look for markers of disease. Sometimes other medical conditions are confused with unipolar depression, including thyroid or hormonal disorders, so it’s important to rule those out. According to the DSM-5-TR, in order to be diagnosed with unipolar depression (major depressive disorder), you need to have had symptoms of a depressive episode for two weeks or more, and experience five or more of the following symptoms:
Depressed mood (or irritable mood in children) Little to no interest in activities that used to give you pleasure A noticeable change in appetite or weight Challenging sleep issues An inability to stop moving (agitation) or acting extremely sluggish Low energy, inability to concentrate, and fatigue Feelings of intense worthlessness, self-blame, and guilt Trouble thinking clearly or making everyday decisions Thoughts of death or suicide

There are several factors that contribute to unipolar depression. Usually it’s not just one factor that causes the condition, but several taken together—a perfect storm of causes, so to speak. Some of the most common causes of unipolar depression include:
Having a family member with depression (heredity is a contributor in 35% of cases) A history of childhood abuse, including physical, sexual, and mental abuse Differences in brain chemistry and neurology
Additionally, certain risks factors may make you more prone to developing unipolar depression, such as:
