What is Depression?

Depression (also known as major depressive disorder) is a medical illness that detrimentally affects how an individual thinks, feels, and acts. It causes severe sadness and loss of interest in daily life activities. If left untreated, it can lead to an array of physical and emotional problems and affect every aspect of life.


Throughout human history, the concept of depression was present in every phase of history. With time and evolving knowledge, the definition also changes.

Nowadays, it is known as a major depressive mood disorder specified by sad feelings, characterized by past events. Let’s look into the history of how its meaning gets melded and changed over the years.

    Origin Of Depression

Hippocrates (Father of Medicine), was an ancient Greek physician who considers all bodily functions to work by four fluids, known as humor.

Humor consists of blood, black bile, yellow bile, and phlegm. His concept was that adequate balance between these fluids manifests as good health and if they are out of balance, it can lead to different diseases.

Later, Greek physician and philosopher Galen adds to Hippocrates’ view and states that personality types of humans also come from an excess of these internal fluids.

As stated by humor theory, a melancholic or gloomy personality is the result of an excess of black bile.

At that time, sad people were considered introverted and over-thinkers. This melancholic concept leads to our present understanding of the great depression.

    A Dual Approach

In the 19th century, German psychiatrist Emil Kraepelin started to mention melancholic personality types as “depressive states” due to the persistent gloomy mood.

He introduced a dual approach to viewing severe depression and divided it into two categories; manic depression and dementia praecox.

Manic depression occurs due to an external factor, like the death of a loved one. It was expected that it is episodic and will go away with time. 

On the other hand, severe depression that does not originate from external sources originates from the individual’s psyche. Karpelin’s concepts are still valid to this day and hold critical value in the understanding of depression.

    Sigmund Freud’s Point Of View

Sigmund Freud, who is considered the father of psychoanalysis, gives his point of view on depression in a 1917 essay and writes the meaning as  “Morning and Melancholia”.

He defined melancholy the same as the current depression definition, expressing that melancholy is a sense of loss that occurs when an unknown object has been lost due to mind repression.

He proposed that depression and anxiety affect the traditional mourning process, making the person feel more sadness than others.

This state of mind makes an individual feel more hopeless, angry, and stuck in gloominess. Depressed people blame themselves for the loss of the loved one while keeping their memory in their hearts.

    Modern-Day Approach

Adolf Meyer, a Swiss psychiatrist, distinctly describes depression definition. He emphasized taking into account biological and mental elements as contributing factors to the great depression causes.

Nowadays, the understanding of depression and anxiety has changed with consistent research and studies. This leads to different treatment medications for depression and what manifests as a depressive state.

If you feel any of the symptoms, consult your medical and mental health professional. One of the treatment approaches is Deep TMS, integrating medicine into the regime can suppress the symptoms.

With the advancement and shifts in culture, research, and philosophical perspective, multiple views, and treatment options are available for patients. People can seek help and benefit from many different medications for depression approaches and methods.
