Bipolar disorder is a treatable disease, but it is often either misdiagnosed or not detected until too late--with sometimes devastating consequences. A research team that includes Michèle Wessa, of the Central Institute of Mental Health in Germany has conducted a systematic review of functional magnetic resonance imaging (fMRI) and discovered that there are possible biomarkers that could detect bipolar disorder before symptoms become too serious. "These results support and refine previously proposed neurobiological models of the disorder and suggest that an imbalance between cortical-cognitive and limbic brain networks may serve as a neurobiological marker of bipolar disorder," Wessa is quoted as saying in an article in PsychCentral.
