Depression is a common and serious medical illness that negatively affects how you feel, the way you think, and how you act.

Depression causes feelings of sadness and/or a loss of interest in activities once enjoyed. It can lead to a variety of emotional and physical problems and can increase a person’s ability to function at work and at home.

Main causes of Depression:-

There are a number of factors that may increase the chance of depression, including the following:

According to the researchers, there are some differences in the brain of the people having clinical depressions that of the people who do not have.  For instance :- The hippocampus, a small  part of the brain that is  vital to the shortage of memories appears to be smaller in some people with a history of depression than in those who have never been depressed. There is a fewer serotonin receptor a smaller hippocampus consists of.

Serotonin is one of many brain chemicals known as neurotransmitters that allow communications across circuits that connect different brain regions involved in processing emotions.

Abuse:- Past Physical, Sexual, and Emotional abuse can increase the vulnerability to clinical depression later in life.

Conflict:- Depression may result from personal conflicts or with family members or friends.

Death or Loss:- sadness or grief from the death or loss of a loved one.

Genetics:-  The risk of depression might be increased genetically through the parents.

Major events:- Even good events such as starting a new job, graduating, or getting married can lead to depression. So can moving, losing a job or income, getting divorced, or retiring.

Serious Illnesses:- Major illness and some other type of medical condition is also responsible for depression.

Substance Abuse:- Nearly 30% of people with substance abuse problems also have major or clinical depression.

  • If depression or other mental illnesses run in your family?

If you have a history of drug or alcohol abuse.
