To be or not to be a bipolar disorder patient: problems with diagnosis

The diagnosis of bipolar disorder (BD) is predominantly clinical. Some authors have suggested that BD is underdiagnosed and that many patients, particularly those with major depressive disorder, actually have BD. Some studies have suggested that BD is wrongly diagnosed, probably because of the idea of a "bipolar spectrum." To address this potential overdiagnosis, clinicians should carefully and systematically assess whether symptoms are included in diagnostic criteria and include the individual context of the patient.
