[Depression--cause or consequence of inability to work or disability?]

Probably it won't be easy to answer the question of causality between inability to work and depression. But the search for an answer is worth while: The answer is not only the basis of secondary administrative work like certificates but also of primary therapeutic measures. The article describes the necessary knowledge and the practical know how. It also names the problems of doctors as part of the social insurance system. Finally besides administrative measure certificates may be regarded as therapeutic intervention with effects and side effects. And depression may also be regarded as specific state in our society.
