One out of ten people in the world suffer from depression, and scientists may finally have an idea why. It's all in our rewards system.
An international research team has identified depression is closely associated to the lateral orbitofrontal cortex.
This is the part of the brain responsible for "non-rewards." According to the team, this is why people that are depressed are often lost, disappointed and have very low self-esteem.
However, this may imply that depression roots from one's satisfaction from a different perception of reality. Additionally, in this"reality," they are "lost," "will be disappointed" and they are loathed by others.
People often spend thousands of dollars in therapy. This is in hope that they can actively help patients combat these mental conditions properly. Moreover, this will help them readjust to society and calibrate their emotional responses.
Additionally, the mental condition is also linked to our memory system. It seems this is why a lot of depressed individuals have difficulty accepting happy memories.
The root of all sadness
The study, published in Brain
, explained that finding out the root of the mental condition can help physicians have physical methods to combat the condition.
The researchers, hailing from England's Warwick University and China's Fudan University, said depression is common in today's society and needs to be dealt with properly.
Sadly, there are even traces of Prozac, an anti-depressant, in tap water in London.
The study used the brain scans of 1,000 people in China using high-precision MRI. Moreover, this allowed them to actively check the connection between the medial and lateral orbitofrontal cortex.
Discovering the physical root of depression will be a breakthrough in the discipline. This will allow physicians to figure out more advanced treatments that can work against combating depression.
Additionally, this research could hopefully find the root of depression and other mental
However, progress in this field can allow various researchers in other fields to explore other illnesses as well. Success in this venture will help them find ways to actively treat the illnesses without spending so much on medication
This may even pave way to cheaper methods of therapy and allow physicians to accurately address problems of depression that were previously so hard to decipher.
