Depression can be a mild disease that only causes some annoyance in daily life, but can also get very serious and make a person totally unable to work and unable to participate in social life. By depression of some severity, there is also a greater risk of suicide. Depression can occur in all age classes. A lack of interest in work, withdrawal from social life and difficult mood can be signs of depression.

This book explores depression, how to recognise it and how to treat it.
