Depression will put you at risk for brain shrinkage

According to a study by American scientists, people who work under stress or have mild depression, may be brain shrinking and emotionally and mentally degraded.

Researchers have discovered one of the reasons why this happens is because a genetic switch causes disconnection in the human brain and leads to depression.

The findings of the study show that genetic transformation is known as a copy, preventing the expression of certain genes needed for the formation of synapses between brain cells, thereby reducing brain volume. The study was reported in Nature Medicine.

Professor of psychiatry, neurobiology and pharmacology at Yale University, and author of the study, Ronald Duman said: 'We want to test that stress is a cause. the depletion of brain synapses (joints of nerve cells in humans) or not?

At the same time, he added: 'We find that common circuits involved in emotional activities, as well as awareness, will be broken when this version element is activated.'

The team analyzed the tissues of depressed and depressed patients, donated from a brain bank and searched for different gene activation patterns, they found the brains of depressed patients had The level of gene expression is less than the requirements for brain functions and structures.
