title: Recurrent brief depression revisited.
abstract: Recurrent Brief Depressive Disorder (RBD) is a well-defined and prevalent mood disorder with an increased risk of suicidal behavior and significant clinical impairment in the community and general practice. Occurring at least monthly with depressive episodes lasting only a few days defines recurrent Brief Depressive Disorder. The lifetime co-occurrence of both RBD and Major Depressive Disorder (MDD), called Combined Depression (CD), substantially increases the risk for attempted suicide, even more than that known for 'pure' MDD. The diagnostic criteria for RBD found in the ICD-10 and DSM-IV are helpful in research and clinical routine as well as several methodological issues, which make clinical diagnostic and drug response evaluation of RBD very different from MDD. Formal differences in the course of RBD and MDD require different designs for drug treatment studies. Denials of disorder, specific methodological requirements, and highly selected patient samples have probably been responsible for false negative results in double blind, placebo-controlled treatment studies. Although several authors reported successful treatment of RBD with different compounds in about 60 patients, it is still not possible to deduce a treatment algorithm for RBD to date. Obviously future treatment studies without the limitations of previous studies are clearly required for RBD. Results of ongoing studies will soon provide the first data on the biological underpinnings of RBD.
