Although these two disorders are similar, there are marked differences, different causes and different treatments. Bipolar and Unipolar Disorders Bipolar and unipolar disorders are two different disorders that affect millions of people; however, there are differences between the two mood disorders. Bipolar is differentiated by two distinct phases of mania and depression, and the rapid cycling of these two phases is a key feature of bipolar. (Jackson, 2010). Unipolar is a major depressive mental disorder usually related to loss of pleasure from daily activities, low mood, and low self-esteem. Additionally, bipolar people go through a manic phase; However, people with unipolar disorder do not go through a manic phase. The manic phase occurs when a person exhibits amplified excitability, rapid or unreasonable thoughts, insomnia, and increased sexual promiscuity. However, people with bipolar and unipolar disorder experience depression. Depression is when a person loses interest in activities they usually do and begins to feel worthless, guilty, or sad.
