Not only traumatic events, but good incidents like getting married, graduating or having children can also trigger depression. Some events that can commonly cause depression are:

These are just few examples of such events .Many other such relatable incidents can occur in life which can cause depression in people.
Many studies have stated that a depressed person’s brain loses volume at several regions but got back to normal after treatment. Though the specific cause has still not been clearly defined, it is assumed that neurotransmitters such as Serotonin, Dopamine and Norepinephrine influence the emotions of happiness in a person. Recent research studies have pointed out that a change in the neurotransmitters functioning may contribute to cause depression. Antidepressants help to balance these neurotransmitters, especially serotonin. A major head injury, surgery or accident may also cause the change in the emotions and thinking process, and cause depression.
Studies have suggested that people can inherit depressive disorders from bloodline too. It has been studied that people who have a family member suffering from depression previously, are more likely to develop depression rather than those who don’t have.
Another major cause for depression can be hormonal changes occurring within the body. Hormonal change occurs with change in bodily processes like pregnancy, birth of a baby, menopause, menstruation, puberty, aging or thyroid illness. There have been cases of mothers isolating themselves from their newborn following postpartum depression. Postpartum depression is a serious form of depression that occurs after the birth of a child.
Depression may also occur with the change in the season. Many people tend to feel distressed when winter or summer arrives. The body feels lethargic and tired and the person may also feel less interested to do his/her regular activities. This is known as Seasonal Affective disorder (SAD).
