Editorial Note on Depression in aged people

Yasuo Iwasaki

Have you ever wondered what causes clinical depression? Perhaps you have been diagnosed with major depression, and that's made you question why some people get depressed but others don't. Depression is a complex disease. No one knows exactly what causes it, but it can happen for a variety of reasons. Some people have depression during a serious medical illness. Others may have depression with life changes such as a move or the death of a loved one. Still others have a family history of depression. Those who do may have depression and feel overwhelmed with sadness and loneliness for no known reason.
