In bipolar disorder (BD), current irritability was robustly related to current/prior anxiety, a recent study found. Researchers assessed outpatients referred to the Stanford Bipolar Disorders Clinic during 2000 to 2011, using the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation. They found:
• Among 497 BD outpatients (239 Type I, 258 Type II, 58.1% female; mean ± SD age 35.6 ± 13.1 years), 301 (60.6%) had baseline current irritability.
• Patients with vs without current irritability had significantly higher rates of current anxiety (77.1% vs 42.9%) and a history of anxiety disorder (73.1% vs 52.6%).
• Current irritability was more robustly related to current anxiety than to current anhedonia, sadness, or euphoria, and current irritability-current anxiety associations persisted across current predominant mood states.
• Current irritability was more robustly related to past anxiety than to all other assessed illness characteristics, including 1o family history of mood disorder, history of alcohol/substance use disorder, bipolar subtype, and current syndromal/subsyndromal depression.
