What Are The Main Causes Of Depression?

No one is sure what causes depression. Experts say that depression is caused by a combination of factors that include human genes, their biochemical environment, personal experience and psychological factors.

Search with MRI (magnetic resonance imaging) scans showed patients with clinical depression had less brain volume in several regions, including the frontal lobe, basal ganglia and hippocampus. They also found that, after the treatment of the hippocampus is returned to normal size.

Some say that genes play a role in the onset of depression. By studying the case of major depression in identical twins (whose genes are identical to 100%) and non-identical twins (whose genes are identical to 50%) found that heritability is a major contributing factor in the risk of developing depression.

Experts say depression is not caused simply by the level of a chemical being too low and another too high. On the contrary, many different chemicals are involved, working both within and outside the nerve cells. There are “millions, even billions of chemical reactions that make up the dynamic system that is responsible for your mood, perceptions, and how you experience life.”

A terrible experience can trigger a depressive illness. For example, the loss of a family member, a difficult relationship, sexual abuse.

For example, the hippocampus a small part of the brain that is vital for storing memories, appears to be smaller in some people with history of depression than those who have never been depressed.  A smaller hippocampus has fewer serotonin receptors. Serotonin is one of many brain chemicals called neurotransmitters that allow communication between the circuits that connect different brain regions.
