Causes of Depression Disorder

Medical scientists have contributed a lot to our understanding of depression disorder but no one has still found out the mechanism which makes the brain unstable and cause the individual to become depressed. Previously, specialists thought that the cause of depression was the troubling thoughts that occupy the minds of people but recently, it is discovered that there are three main factors that make a person depress. These factors can be inherited, biological or environmental.


Many researchers have found out that depression can also be caused by genetic factors. If both of your parents or other relatives have a vulnerability to depression disorder, then you are also likely to have it. In identical twins, if one person is suffering from depression then there are seventy percent chances that his or her twin will also be facing the same issue. Besides that, parents who adopt children can also face depression problems in their adopted child.


Depression can also be caused by chemical imbalance in the brain of the person. This imbalance can cause the level of hormones to increase and decrease causing symptoms of depression to show. Our brain is the most complex part of our body; there are certain types of chemicals in our brain, which circulate through neurotransmitters. Our body is dependent on four types of neurotransmitters, neropinephrine, serotonin, dopamine and acetylcholine. Depression is caused by implication of serotonin and neropinephrine. Serotonin is linked with our sleeping habits and lack of serotonin causes the person sleeping problems, irritability, and fear. Similarly deficiency in neropinephrine cause people to get sick, lose their focus and fatigue.


This cause plays the main role in depressing the people. Many times, people experience emotional problems in their lives, which change their emotional and physical reactions. People keep thinking about these problems and damage their brain, which in result adrenaline or other stress hormones. Emotional problems include; family problems, unstable personal life, financial crisis, abuse, death of a loved one etc. This increases the burden on the mind, which then starts to work abnormally causing anxiety, headaches, and sleeplessness. This abnormality of the brain also affects other parts of the body like heart and liver.

It is necessary to consult with a doctor when one experiences the symptoms of depression, so that they can help to cure it before it gets exacerbate. In worse cases, depression can also lead patients to harm others or themselves and can even result in suicide attempts.
