DSM-5 and the removal of the bereavement exclusion

Social factors are also relevant when it comes to diagnosing depression. An exclusion for the diagnosis of depression due to bereavement was originally observed at the back of the DSM-III, noting that because "a full depressive syndrome frequently is a normal reaction to the death of a loved one", the patient's condition was better understood as Uncomplicated Beareavement. This exclusion became part of the diagnostic criteria in the DSM-III-R and DSM-IV, where individuals experiencing depression symptoms were not considered depressed if the symptoms were in response to the death of a loved one and ended within two months. However, this bereavement exclusion was removed under DSM V, allowing a depression diagnosis to be made under these conditions.
