Manic depressive disorder, also known as bipolar disorder, is a mental health condition characterized by extreme mood swings. While "manic depressive disorder" is the traditional term still used by some clinicians, there are several synonyms that have gained popularity in recent years. One such term is "bipolar disorder," which is a more accurate and less stigmatizing term that describes the two poles of mood experienced by those with the condition. "Mood disorder" is another term used to describe the broad category of mental health conditions that include bipolar disorder. Ultimately, the terminology used to describe this condition is less important than understanding and addressing the symptoms and impacts of the disorder on individuals and their families.
