Question: what is the difference between bipolar 1 disorder and bipolar 2 disorder?
Answer: The main difference between bipolar 1 and bipolar 2 disorders lies in the severity of the manic episodes caused by each type. A person with bipolar 1 will experience a full manic episode, while a person with bipolar 2 will experience only a hypomanic episode (a period that's less severe than a full manic episode).
