Depression is a common emotional disorder that often puts an individual in a prolonged state of anxiety and sadness. This is a mental disorder that affects one physically and emotionally. Depression is much more than any momentary blue and therefore doctors have classified as a disease. Although it can be treated, while some respond well to treatment, others can not cope easily and that scientists have not yet discovered why that is the case. But all research on the disease has yielded some surprising data. Here are the top 5:

1. Depressed people have smaller parts of the brain

Scientists have found that people who suffer from depression tend to have a smaller hippocampus (part of the brain responsible for controlling emotions and memory ). The reason behind this is not clear. However, researchers have speculated that the stress hormone, cortisol it releases in larger amounts in the brains of people with depression may have a contractionary effect on the hippocampus. They have also found that people who are born with a smaller hippocampus are also more likely to suffer from the disease.

2. Depression is associated with inflammation

Scientists have found a link between depression and inflammation . They theorize that chronic inflammation associated with certain diseases can lead to depression. To validate their findings, experts administered endotoxin (drugs that help stimulate inflammation) of healthy people and found the appearance of a depressive behavior among these individuals.

3. It is linked with several chemical imbalances in the brain

has been shown that alteration of some substances brain chemical (also known as neurotransmitters as norepinephrine and serotonin) is associated with depression. This is not a simple correlation as such anomalies varies from person to person. From clinical studies, it was identified that only 25% of people, which exhibits a decreased level of neurotransmitters, suffer from depression. However, there are some depressed individuals also exhibit abnormally high levels of serotonin and norepinephrine. It became apparent from the findings of experts that depression is related to several altered patterns of behavior and thought and therefore the hypothesis that this type of learning and thinking sequence behavior related to depression can affect levels of neurotransmitters differently in different people.

This is one reason why many people do not respond well to antidepressant drugs. They have not been able to solve the puzzle however, and requires a lot of research to understand the complex mechanisms involved in depression.

4. Depression is hereditary

has been identified by researchers that depression runs in families and may even spread through several generations. They have even found that some people whose genes lead to produce a very low level of a molecule neuropeptide Y (NPY) are more likely to adapt negative stimuli and therefore more likely to suffer from depression.

5. Some medications can cause depression

There are certain medications that can lead to depression. These drugs can cause an alteration of brain chemicals in one way or another. Drugs that help control blood pressure acne problems, along with some statins and oral contraceptives may make you feel depressed.
