The British research institute has revealed in a recent study that the disease of depression is not the result of any chemical imbalance in the brain, but negative events and experiences in life are the cause of mental stress.
A clinical study at the University of London examined the relationship between depression and serotonin activity in a cohort of thousands of people.
In addition, the study analyzed past research reports and details on depression, which revealed that the decades-old belief that serotonin, a chemical in the brain, is wrong. Disturbance of balance causes depression.
According to a paper published in the journal Molecular Psychiatry, researchers say that serotonin is a chemical that plays a very important role in mood, sleep, digestion and other bodily functions, but all the experiments and analyzes did not find such evidence. Serotonin levels or the activity of this chemical cause depression.
For decades, serotonin was thought to be the cause of depression, leading to patients being prescribed sedatives to increase levels of the chemical in the brain. New research has raised many questions about the use of these drugs.
The researchers also say that to control depression, many patients use sedatives to balance serotonin levels in the brain. But recent research has found no link between serotonin levels and depression.
These medications can reduce the severity of depression symptoms, but the underlying cause is different.
Researchers say that there may be a link between depression and negative life experiences.
Researchers say that negative events and experiences increase the risk of depression in people, the more negative experiences a person has in life, the higher the risk of depression.
