How to know if I have bipolar depression?

Bipolar disorder was previously known as ‘manic depression’ because it is a combination of two conditions, ‘mania’ and ‘depression’. However, this term is no longer used. Screening for depression is one component of diagnosing bipolar disorder. Some of the depression screening criteria your doctor will ask about when diagnosing bipolar disorder are sadness, loss of interest in activities, guilt, low energy, lack of concentration, poor appetite, suicidal thoughts, and feeling like you are moving very slowly.
