Most of us think of extreme sadness when talking about depression. However, depression is a mood disorder that is much more than just sadness or grief. It may look very different in two different individuals and may even go unnoticed in some.
Long-lasting and serious depression may become a major health concern and may affect almost every aspect of a person’s life. As per the World Health Organisation, nearly 264 million people are affected by depression in the world. The condition may lead to suicide in the worst-case scenario - suicide is one of the leading causes of death in the age group of 15 to 29.

Types of depression
Depression may be persistent or it may show up in recurrent episodes. The National Institute of Mental Health, USA categorises depression into the following types:
