Throughout history, from the writings of Hippocrates and Galen to the contemporary Diagnostic and Statistical Manual of Mental Disorders (DSM), humanity has recognized depression (historically termed melancholia) as a debilitating mood disorder. It is crucial to distinguish depression from ordinary sadness; it often emerges without a clear cause or with an intensity and duration that seem excessive relative to any identifiable trigger.
While pharmacological treatments have been a mainstay since the mid-20th century, modern understandings of depression acknowledge a multifaceted mix of social influences that extend beyond simple biochemical imbalances.
The Experience of Depression
Depression can manifest as a profound sense of detachment, accompanied by persistent sadness, fatigue, decreased energy, and changes in appetite, weight, and sleep patterns. In severe cases, crushing feelings of worthlessness can overwhelm an individual, leaving them with immense existential pain.
The prevailing contemporary view is that chemical imbalances in the brain contribute to depression, leading to a strong emphasis on pharmaceutical treatments. Lifestyle adjustments, exercise, and therapy can also prove beneficial. However, in particularly severe cases, neither drugs nor therapy may provide sufficient relief. There is a strong correlation between clinical depression and suicide, with an estimated 95% of those who commit suicide experiencing depression.
Historical Perspectives on Depression
The core symptoms of depression have been documented for centuries. From Hippocrates (406-370 BC), who coined the term “melancholia,” to the modern DSM-5, descriptions of depression share remarkable similarities.
Hippocrates’ Humoral Theory posited that bodily health depended on the balance of four vital fluids: phlegm, blood, yellow bile, and black bile. Imbalances were believed to cause illness, with melancholia arising from an excess of black bile. Aristotle further explored the dangers of black bile, suggesting its effects contributed to a range of conditions including melancholy, depression, and anger.
The Evolution of Depression: From Melancholia to Modern Understanding
The concept of depression has its origins in the ancient understanding of melancholia, a term used from classical Greece through the early modern era. The historical lineage of depression refutes the misconception that it is a solely modern phenomenon.
Over centuries, perceptions of melancholia shifted. Aristotle associated it with exceptional intellect, while 18th-century artists and intellectuals sometimes romanticized the condition. In 1917, Sigmund Freud connected melancholia to unresolved grief, theorizing that the sufferer experiences an internal loss of self. By the late 19th century, “melancholia” and “depression” were often used interchangeably, with depression ultimately becoming the dominant term.
Antidepressant Development
As the understanding of depression evolved, so too did treatment approaches. The 1950s saw the advent of antidepressant medications, although early options (tricyclics and MAOIs) had significant side effects.
A breakthrough came in the 1980s with Selective Serotonin Reuptake Inhibitors (SSRIs). This class of antidepressants offered relief with fewer side effects. While pharmaceutical marketing has undoubtedly played a role in the widespread use of antidepressants, these medications provide genuine relief for many individuals worldwide.

Depression in the Modern World
Sociologist Alain Ehrenberg posits that the perception of depression has shifted since the 1950s. It is less frequently defined by internal suffering and melancholy, and increasingly framed as a “pathology of action.” This perspective emphasizes the depressed individual’s reduced capacity for work, relationships, and general engagement with life. Such a view poses a challenge in a society that values individual accountability and proactive initiative.
While a chemical imbalance in the brain, such as low serotonin levels, may be a contributing factor to depression, the condition has undeniable social dimensions. The question remains: what causes these chemical imbalances in certain individuals? The stresses of modern life – widening inequality, precarious employment, technology-dominated social interactions, and increasing isolation – create a complex landscape where depression thrives. These factors underscore that a simple biochemical explanation is insufficient.
