depressive personality disorder
a diagnosis in the appendix of DSM–IV–TR (i.e., proposed but not given official recognition in the manual) that is characterized by glumness, pessimism, a lack of joy, the inability to experience pleasure, and motor retardation. Feelings of loss, a sense of giving up, and an orientation to pain are notable. There are vegetative signs, despair regarding the future, and a disheartened outlook. Clinicians attempt to differentiate this disorder from dysthymic disorder. Mention of the diagnosis has been removed from DSM–5.
