The Main Causes Of Depression

Depression is rarely a single cause. It involves a combination of genetic reasons, biological and personal. For some, depression is a matter of discipline, failure, or emotional weakness. Others believe that genetic causes, which in turn are not allowed to treat. So speaks of vulnerability and stress is a major cause of depression. Vulnerability and stress are considered that many of the researchers, two mega-factors that trigger depression.

But many of the new discoveries in brain research shows that things are different. We know that there are many genetic, biological agents, and other personal crises at different stages of life affects different regions of the brain at various levels, and change it.

The vulnerability of major depressive disorder is especially marked stress management: alarm system of the body is off the rails due to some internal factors (such as changes in the concentration of certain nerve messengers) and the external pressure (eg, a crisis existential), because some of the personality structure, tolerance of people have been reduced because of the depression.

To understand depression, genes closely, body, head, life experience and life story to break. This interaction between biological and social mechanisms is crucial.

Individual factors: the genetic tendency to depression may be genetically determined. Previous studies show that if about 20 percent of depression identified by genetic causes or inherited in the family, the twins and because of caregivers. Both studies show that the genetic factor is only a partial factor. The rise (and severity) of depression is always dependent on the social environment that includes family and social relationships.

Biological causes: causes of depression are not only in the life history of the patient, but also biological. The changes in the brain and neurotransmitters play a very important for the emergence of depression.

The leading theory of the biological causes of depression focuses on the lack of norepinephrine and serotonin. These factors are based on the tricyclic antidepressants and monoamine oxidase inhibitors, motivation, mood, and the attorney for the brain structures, and the increasing concentration of these neurotransmitters. This leads to brighten the mood. Antidepressants to prevent the metabolism or the light of these neurotransmitters in the nerve cells so as intermediate messengers in the cell area of ​​the cranial nerves are available.

It can therefore be assumed that a deficiency of the neurotransmitter is the cause of depression associated with the connection. It is still unclear, the disorder is a neurotransmitter to cause epidemic disease. Maybe it's just a consequence of other physical cause of depression.

Children and Youth: Epidemiological studies show that about one percent of children under six years, two percent of children of school age and five percent of adolescents with clinically significant depressive disorders. Therefore, the environment in early childhood may be particularly important for the development of depression.

About half of all depressive disorders occur in young people aged between 11 and 14. For this reason, psychologists warn that parents should take the emotional problems of children and young people in puberty hood severe criticism.

Life events: stressful event, is still an increased risk of depression about a year and a half, although this eventuality is not necessarily linked to depression.

A job loss is recognized the prototype of a stressful life event: Nearly a quarter of the unemployed are depressed 2-7 months after the dismissal.

Other examples of life events associated with depression can have lasting psychological pressure, loss of work or self-esteem, stress, or ongoing financial pressures, physical abuse, physical illness and alcohol dependence.
