Depression Chapter 9


Symptoms and Diagnosis

PART 1

Diagnosing Depression

Although depression may create physical changes in the brain, there is no physical test to determine whether or not someone has depression. Depressive disorder is diagnosed by the presence of certain core emotional and behavioral symptoms. These are known as the DSM-IV Diagnostic Criteria.

For a diagnosis of major depression, at least five of the following symptoms must be present during the same 2-week period and represent a change from previous functioning. For a diagnosis of minor depression, from two to four of these symptoms must be present. For both major and minor depression, at least one of the symptoms must be either 1) depressed mood or 2) loss of interest or pleasure. READ MORE
