Let's distinguish Mania from Depression before we combine these medical terms or identities and derive Bipolar Disorder (or Manic Depression).
By definition, Mania (noun; origin: 13501400) means " excessive excitement or enthusiasm; craze" (dictionary.com).
From The Free Medical Dictionary (http://medical-dictionary.thefreedictionary.com/mania): "Mania is an abnormally elated mental state, typically characterized by feelings of euphoria, lack of inhibitions, racing thoughts, diminished need for sleep, talkativeness, risk taking, and irritability. In extreme cases, mania can induce hallucinations and other psychotic symptoms."
From Merriam Webster's Medical Dictionary, "excitement of psychotic proportions manifested by mental and physical hyperactivity, disorganization of behavior, and elevation of mood; specifically : the manic phase of bipolar disorder."
Then on the opposite end of Mania we have Depression:
Depression (noun; origin: 13501400), a far more commonly overheard term, insights "a condition of general emotional dejection and withdrawal; sadness greater and more prolonged than that warranted by any objective reason" (Based on the Random House Dictionary, © Random House, Inc. 2009).
Mix these two definitions and we get what is known as Bipolar Disorder, or Manic Depressive Disorder. But what does this term actually mean?
From MedicinePlus [http://www.nlm.nih.gov/medlineplus/bipolardisorder.html]:
Also called: Manic-depressive illness
Bipolar disorder is a serious mental illness. People who have it experience dramatic mood swings. They may go from overly energetic, "high" and/or irritable, to sad and hopeless, and then back again. They often have normal moods in between. The up feeling is called mania. The down feeling is depression.
Bipolar disorder can run in families. It usually starts in late adolescence or early adulthood. If you think you may have it, tell your health care provider. A medical checkup can rule out other illnesses that might cause your mood changes.
Untreated, bipolar disorder can result in damaged relationships, poor job or school performance, and even suicide. However, there are effective treatments: medicines and "talk therapy". A combination usually works best.
Also, from All About Life Changes:

Manic depressive - What does it mean?
Manic depressive refers to mood swings from overly high (manic) to overly low (depressed). Another name for manic-depressive illness is bipolar disorder. This refers to a persons mood alternating between poles of mania (highs) and depression (lows). Bipolar disorder is a brain disorder that causes unusual changes in the persons mood, energy, and ability to function.
Manic-depressive illness or bipolar disorder affects both men and women. Although it can start at any age, it usually begins in late adolescence. Bipolar disorder is found among people of all ages, races, ethnic groups, and social classes. It appears to have a genetic link and tends to run in families. Unfortunately, in addition to affecting the sufferers life, this disease also has the potential to devastate the lives of the caregivers and those in the immediate family circle.
Moreover, from the American Heritage dictionary, "A manifestation of bipolar disorder, characterized by profuse and rapidly changing ideas, exaggerated sexuality, gaiety, or irritability, and decreased sleep... Violent abnormal behavior."
Further, Mayo Foundation for Medical Education and Research [http://www.mayoclinic.com/print/bipolar-disorder/DS00356/DSECTION=all&METHOD=print] has types of the Bipolar Disorder listed in seperate classifications:
Types of bipolar disorder
Bipolar disorder is divided into two main subtypes:
Aside from the weighty medical jargon and polysyllabic terms, "those people" begin to have many identifiable characteristics and traits we may identify in an abundance of other people. Then, when we think long enough, we see those same behaviors inside ourselves. It's all relative. For instance, what does the excuse "I do not know what I was thinking!" bring to mind? Or another: "I've had way too much coffee already today!" Makes us all stop and think...
