The detection and treatment of depression in the physically ill.

DEPRESSION AND CHRONIC PHYSICAL ILLNESS ARE IN RECIPROCAL RELATIONSHIP WITH ONE ANOTHER: not only do many chronic illnesses cause higher rates of depression, but depression has been shown to antedate some chronic physical illnesses. Depression associated with physical illness is less well detected than depression occurring on its own, and various ways of improving both the detection and treatment of depression accompanying physical illness are described. This paper is in four parts, the first dealing with the evidence for depression having a special relationship with physical disorders, the second dealing with detection of depression in physically ill patients, the third with the treatment of depression, and the fourth describing the advantages of treating depression among physically ill patients.
