Clinical depression is a serious medical condition that is also commonly
referred to unipolar and major depressive disorder. This type of
disorder is progressive, which means that over time, the symptoms can
become much worse.
It is not at all unusual for people with this type of depression to isolate themselves from close friends and members of the family. Some of the common signs that you should watch for would include extreme feelings of being sad, and the depressed person will generally show signs of despair as well. When clinical depression is left untreated, there is many times that the individual will need to be hospitalized as a way to prevent the person from being able to cause themselves any type of harm.
