Do social anxiety disorder patients belong to a bipolar spectrum subgroup?

Background been proposed that all forms of bipolar disorder–perhaps all primary affective disorders–are best conceptualized as a spectrum of related illness, clinically overlapping but not necessarily genetically uniform illnesses. We aim to describe with retrospective methodology the demographic, clinical, and therapeutic response in a group of social anxiety disorder (SA) patients who improves while taking antidepressants and compare them with bipolar II (B-II) patients. s outpatients (DSM-IV) were diagnosed and naturalistic efficacious treated with selective serotonin reuptake inhibitors (SSRI). Their demographic, clinical features and therapeutic response were compared with 41 DSM-IV bipolar II patients in their starting evaluations in our outpatient clinic in the Federal University of Rio de Janeiro, Brazil. s is a sub-group of SA patients who improves while taking antidepressants and presents a clear hypomanic phase. Their improvement is identical to a mild/moderate hypomaniac state. Without the antidepressant, the symptoms of SA return. The SA and B-II patients have a similar number of previous depressive episodes, alcohol abuse, suicide attempts, and family history for mood disorder. tions a retrospective data description based on a naturalist follow-up. sion A patients have demographic, clinical and therapeutic features similar to B-II patients and they might just be a Bipolar-III sub-group with a higher level of complains to social situations and without spontaneous hypomania during lifetime.
