History of bipolar disorder

Cyclical variations in moods and energy levels have been recorded at least as far back as several thousand years. The words "melancholia" (an old word for depression) and "mania" have their etymologies in Ancient Greek. The word melancholia is derived from melas/μελας, meaning "black", and chole/χολη, meaning "bile" or "gall",^[1] indicative of the term's origins in pre-Hippocratic humoral theories. A man known as Aretaeus of Cappadocia has the first records of analyzing the symptoms of depression and mania in the 1st century of Greece. There is documentation that explains how bath salts were used to calm those with manic symptoms and also help those who are dealing with depression.^{[citation needed]} Even today, lithium is used as a treatment to bipolar disorder which is significant because lithium could have been an ingredient in the Greek bath salt.^[2] Centuries passed and very little was studied or discovered. It wasn't until the mid-19th century that a French psychiatrist by the name of Jean-Pierre Falret wrote an article describing "circular insanity" and this is believed to be the first recorded diagnosis of bipolar disorder. Years later, in the early 1900s, Emil Kraepelin, a German psychiatrist, analyzed the influence of biology on mental disorders, including bipolar disorder. His studies are still used as the basis of classification of mental disorders today.^{[citation needed]}

The linguistic origins of mania in relation to bipolar disorder

The linguistic origins of mania, however, are not so clear-cut. Several etymologies are proposed by the Roman physician Caelius Aurelianus, including the Greek word ""ania", meaning to produce great mental anguish, and "manos", meaning relaxed or loose, which would contextually approximate to an excessive relaxing of the mind or soul.^[3] There are at least five other candidates, and part of the confusion surrounding the exact etymology of the word mania is its varied usage in the pre-Hippocratic poetry and mythologies.^[3]

Relationship between mania and melancholia

The idea of a relationship between mania and melancholia can be traced back to at least the 2nd century AD. Soranus of Ephesus (98–177 AD) described mania and melancholia as distinct diseases with separate etiologies;^[4] however, he acknowledged that "many others consider melancholia a form of the disease of mania".^[5]

The earliest written descriptions of a relationship between mania and melancholia are attributed to Aretaeus of Cappadocia. Aretaeus was an eclectic medical philosopher who lived in Alexandria somewhere between 30 and 150 AD.^[6][7] Aretaeus is recognized as having authored most of the surviving texts referring to a unified concept of manic-depressive illness, viewing both melancholia and mania as having a common origin in "black bile".^[7][8]

Origin of bipolar disorder as a mental illness

A clear understanding of bipolar disorder as a mental illness was recognized by early Chinese authors. The encyclopedist Gao Lian (c. 1583) describes the malady in his Eight Treatises on the Nurturing of Life (Zun Sheng Ba Qian).^[9]

The basis of the current conceptualisation of manic-depressive illness can be traced back to the 1850s; on January 31, 1854, Jules Baillarger described to the French Imperial Academy of Medicine a biphasic mental illness causing recurrent oscillations between mania and depression, which he termed folie à double forme ('dual-form insanity').^[10] Two weeks later, on February 14, 1854, Jean-Pierre Falret presented a description to the Academy on what was essentially the same disorder, and designated folie circulaire ('circular insanity') by him.^[11] The two bitterly disputed as to who had been the first to conceptualise the condition.

These concepts were developed by the German psychiatrist Emil Kraepelin (1856–1926), who, using Kahlbaum's concept of cyclothymia,Cite error: Closing </ref> missing for <ref> tag^[12] Jung's distinction is today referred to in the DSM-IV as that between 'bipolar I' (mania involving possible psychotic episodes) and 'bipolar II' (hypomania without psychosis). In his paper Jung introduced the non-psychotic version of the illness with the introductory statement, "I would like to publish a number of cases whose peculiarity consists in chronic hypomanic behaviour" where "it is not a question of real mania at all but of a hypomanic state which cannot be regarded as psychotic".^[13][14] Jung illustrated the non-psychotic variation with 5 case histories, each involving hypomanic behaviour, occasional bouts of depression, and mixed mood states, which involved personal and interpersonal upheaval for each patient.^[13]

Initial treatment options

After World War II, John Cade, an Australian psychiatrist, and Shirley Andrews, an Australian biochemist, were investigating the effects of various compounds on veteran patients with manic depressive psychosis. In 1949, Cade and Andrews discovered that lithium carbonate could be used as a successful treatment of manic depressive psychosis.^[15][16] Because there was a fear that table salt substitutes could lead to toxicity or death, their findings did not immediately lead to treatments. In the 1950s, U.S. hospitals began experimenting with lithium on their patients. By the mid-60s, reports started appearing in the medical literature regarding lithium's effectiveness. The U.S. Food and Drug Administration did not approve of lithium's use until 1970.^[17]

Progression from manic-depressive "reaction" to manic-depressive "illness"

The term "manic-depressive reaction" appeared in the first American Psychiatric Association Diagnostic Manual in 1952, influenced by the legacy of Adolf Meyer who had introduced the paradigm illness as a reaction of biogenetic factors to psychological and social influences.^[18] Subclassification of bipolar disorder was first proposed by German psychiatrist Karl Leonhard in 1957; he was also the first to introduce the terms bipolar (for those with mania) and unipolar (for those with depressive episodes only).^[19]

In 1968, both the newly revised classification systems ICD-8 and DSM-II termed the condition "manic-depressive illness" as biological thinking came to the fore.^[20]

Current classification of bipolar disorder

The current nosology, bipolar disorder, became popular only recently,^[when?] and some individuals prefer the older term because it provides a better description of a continually changing multi-dimensional illness.^{[citation needed]}

Empirical and theoretical work on bipolar disorder has throughout history "seesawed" between psychological and biological ways of understanding. Despite the work of (Kraepelin 1921) emphasizing the psychosocial context, conceptions of bipolar disorder as a genetically based illness dominated the 20th century. Since the 1990s, however, there has been a resurgence of interest and research into the role of psychosocial processes.^[21]
