Depression is the most serious mental illness that has not yet been cured. Today, several types of depression have already been identified by scientists. This type of depression affects millions of people all over the world. Researchers are still trying to find the cause and the treatment for different types of depression.
There are two main symptoms of depression. They are sadness and apathy. However, depression can also affect different areas of the body.
Most people feel sad about some events in their lives. It is sad when a loved one dies or when they get divorced. They feel empty when they have lost a job, or they feel sad because of some physical defect or disease that they have suffered. When a person experiences these things, he is depressed.
Some natural chemicals found in the brain produce depression. Some of them are neurotransmitters. These chemicals work like a bridge between your brain and your nerves. The neurotransmitters control the nerves and the feelings and emotions of an individual.
Neurotransmitters are produced by both the brain and the nervous system. It is believed that depression is caused by a chemical imbalance in the brain. If the level of neurotransmitters increases, there is a possibility that depression will appear.
Some people tend to feel depressed if they have experienced certain events in their life. Some events that affect them are the death of a loved one, divorce, sickness, loss of a job, and relationship breakup. In some cases, a person experiences depression if he is scared of something. Such events include a man who is afraid of having a child, and he loses his sense of child.
Major depression, also known as dysthymia, is the most common type of depression. It is caused by stress. The feelings of sadness and isolation created by stress can affect an individual.
In this condition, an individual may feel lonely and sad. He might even have symptoms of depression. He may feel worthless or even obsessed with nothing. If he feels stressed, he may not be able to function at all.
Another type of depression is called dysthymic disorder. This type of depression is caused by lifestyle changes and changes in the brain. Lifestyle change can be a result of getting married or being exposed to trauma.
Dysthymia is caused by the increased production of the hormone dopamine. Dopamine plays a role in controlling the pleasure response.
As a result of hormonal imbalances, the pituitary gland produces the hormone cortisone, which can create symptoms of depression. When the pituitary gland and the adrenal glands do not produce the proper amounts of serotonin, symptoms of depression can appear.
