Full Answer

Depression is a mood disorder that can affect any person and results in a lack of interest in activities and sad feelings. A person may experience depression once in his or her lifetime, but can also have several episodes of depression. The symptoms of depression occur in a person nearly every day, thus interfering with their work performance and relationships with others.

One of the worst symptoms of depression is thoughts of committing suicide. This occurs in people who have severe depression. They tend to talk about death more often or may experience a sudden mood swing, as noted by WebMD. Seeking medical attention and counseling can help a person overcome such thoughts.

The cause of depression is still not known. However, several factors are attributed to depression including hormone changes, brain chemistry, biological differences, life situations and inherited traits. Typically, it's a combination of genetic and environmental factors.
