Bipolar Disorder (manic-depressive illness), if a disorder at all, has been defined as a major affective mood disorder in which one alternates between the mental states of deep and brutal depression and inflated elation- with the depressive episodes occurring more frequently. The disorder affects one's cognition, emotions, perceptions, and behavior- along with psychosomatic presentations (such as pain with depressive episodes, for example). It is thought to be due to a physiological dysfunctional brain in one affected with bipolar disorder, yet the etiology remains entirely unknown.
It is also believed that bipolar disorder presents itself when the affected one is between the ages of 15 and 25 years old. The disorder was entered in the psychiatrists' bible, the DSM, in 1980. Also, bipolar disorder is thought to be correlated with creativity and accelerated growth of neurons if one is affected by it.
Research has determined that as many as 15 to over 30 percent of bipolar disorder patients commit suicide if they are untreated. Also, as many as half of those affected with bipolar disorder also have at times severe substance abuse issues along with this disorder as well. Bipolar patients are also often experiencing anxiety issues that vary, and are treated often as such. The disorder varies as far as severity goes- with some bipolar disorder patients being more affected than others. In fact, there are at least 6 classifications of bipolar disorder, according to the DSM.
Bipolar patients are thought to be symptomatic half of their lives- with depressive episodes occurring more frequently than manic ones. When symptomatic, bipolar patients are thought to be rather disabled, according to some. As many as half of those suspected as having a bipolar disorder are thought to have at least one parent with some sort of mood disorder, which suggests a genetic predisposition to the disorder.
The diagnosis has become more frequent recently. In one decade, the assigned diagnosis of bipolar disorder rose from being about 25 per 100 thousand people to being 1000 per 100,000 people. Most diagnosed with bipolar disorder are not diagnosed based on solid, comprehensive, or psychiatric review that is often absent of valid or standard diagnostic methods. Some believe as many as 5 percent of the human population may be affected by bipolar disorder- which includes as many as 12 million people in the United States.
A subjective questionnaire called the Mental Status Examination is often utilized when diagnosing one suspected has having bipolar disorder. Many believe the diagnosis has increased recently due to the progressive treatment options now available. It is an argument of increased awareness versus over-diagnosis.
Yet the diagnosis is vague, as children and adolescents are often absent in research with bipolar disorder. Many younger than 18 years of age are prescribed atypical anti-psychotics as first line treatment, which is largely not recommended as treatment options. In fact, close to half a million of those younger than 18 years of age are prescribed the atypical anti-psychotic Risperdal alone, it has been determined. The class of medications overall is thought to be prescribed to about 10 percent of those non-adults thought to have bipolar disorder.
