The mood swings caused due to manic depressive illness can range from highstrung & aggressive to down & out, sad & hopeless. These mood swings will go back & forth from one extreme to the other often with times of normal & calm moods between. Bipolar disorder can seem to be something that it's not, as excessive alcohol or drug use, below average school or work performance, & strained personal relationships are often signs of manic depression, & are also common problems among young adults & teens. With the complex nature of this ailment it is often very difficult to diagnose, & can range anywhere from being a petty annoyance to a dangerous lifelong problem. Like most mental illnesses bipolar disorder cannot be identified physiologically by a blood test or brain scan.

There are 2 types of this illness, Bipolar Type I, this is where someone experiences 'full-blown' mania, & Bipolar II, where someone with this type will feel hypomanic 'highs' which will not go to the extemes of 'full-blown' mania. Most professionals concur that there is no single, direct cause of manic depression, & with additional research scientist will begin to better understand the root causes of the illness. It is also difficult to identify from other problems that will occur in adolescents & young adults. With this additional research they may be able to have a more clear understanding of which treatments will work most effectively. Using illicit substances such as amphetamines, cocaine or halucinagentics may also mimic the manic phase, as will certain medical & organic causes like strokes or infections. Medication is the one main key contributor in successful treatment of bipolar disorder, psychotherapy, mental & emotional support, & education about the condition are also required steps of the treatment process.
