Scientists Say Depression Is A Completely Physical Problem!


We all know depression as demoralization, being exhausted, so as something completely cognitive. However, the latest research by scientists prove that depression is an anomaly that completely happens in our brains.

Depression is a serious mood disorder that affects one out of three persons in the world at least once in their lifetime.

20 million adults suffer from depression in the United States every year. While women experience it a lot more than men, depression also weakens the immune system, which causes other problems like a cold.

Suffering from violence, negligence, abuse or poverty for a long time can cause depression, a disease that total of 320 million people deal with around the world.

Depression affects people from every age, geographic region, demographic and social position. Historical figures like Ludwig van Beethoven, John Lennon, Edgar Allan Poe, Mark Twain, Georgia O’Keefe, Vincent van Gogh, Ernest Hemmingway, F. Scott Fitzgerald and Sylvia Plath also had depression and the latest discoveries about this disorder are pretty interesting.

Researchers from Warwick University, England, and Fudan University, China proved that depression signals a lot more than we know and determined the exact area it affects inside the brain.

Here’s what Jianfeng Feng, who is a researcher from both Warwick and Fudan Universities says about depression:

“More than one in ten people in their lifetime suffer from depression, a disease which is so common in modern society and we can even find the remains of Prozac (a depression drug) in the tap water in London.”

According to article published on Brain Magazine; “depression is related to different functional connectivities of the orbitofrontal cortex.”

The orbitofrontal cortex is the part of the human brain that is affected by depression and different functional connectivities of this area cause depression.

Researchers worked with 900 people and scanned their brains using high precision MRI.

421 of these people were diagnosed with major depression. The results showed that the sense of personal loss and low self-esteem were directly associated with the orbitofrontal cortex part of the brain.

The orbitofrontal cortex consists of two different parts and they’re triggered by different experiences.

The middle part of the cortex becomes active when we receive a reward and it functions low with people with a major depression; which also explains why depressive people get a feeling of loss and disappointment.

The studies prove that the lateral parts of the cortex are extremely active in those in the depressive group.

This part of the brain is strongly connected with punishment, one’s sense of self and memory systems in the brain; which brings negative thoughts and recalls bad memories.
