Objective: We used a dimensional measure of mood psychopathology to document lifetime depressive and manic-hypomanic spectrum symptoms in 50 patients with anorexia nervosa (AN).
Method: Participants provided demographic information and completed the Self-Report Questionnaire for Mood Spectrum, a 161-item instrument that documents lifetime symptoms, traits, and behaviors characteristic of threshold and subthreshold mood episodes. Analyses focused on the association of depressive and manic-hypomanic component scores with indicators of clinical severity in AN.
Results: Lifetime severity of depressive (M[SD] = 39.1[13.9]) and manic-hypomanic (M[SD] = 23.8[12.1]) spectrum symptoms exceeded the established thresholds for clinical significance on these scales (ie, score > or =22). There was a positive correlation between the number of manic-hypomanic items endorsed and the number of depressive items endorsed. After controlling for lifetime history of mood disorder, severity of depressive and manic-hypomanic spectrum symptomatology also was associated with a history of self-induced vomiting and suicidality in patients with AN.
Conclusion: These data provide initial evidence for the clinical significance of depressive and manic-hypomanic spectrum symptoms in patients with AN. Future work is needed to determine how mood spectrum psychopathology might impact the course and treatment of AN.

Clinical and metabolic correlates of DSM-5 mixed features in subjects with bipolar depression and mania: A cross-sectional study.
J Psychosom Res
January 2025
School of Medicine and Surgery, University of Milano-Bicocca, Monza, Italy.
Article Synopsis
- This study investigates the clinical and metabolic characteristics of mixed features (MFs) in individuals with bipolar disorder (BD), focusing on those experiencing bipolar depression or mania/hypomania.
- The research included 163 inpatients from May 2020 to July 2023, using various scales and diagnostic tools to analyze symptom severity and metabolic conditions.
- Findings revealed that MFs were linked to anxious distress and obesity, with a tendency to occur less in severely ill patients, suggesting these factors could enhance the assessment and management of MFs in BD.
Seasonal mood variation in youth and young adults with bipolar spectrum disorder: A longitudinal prospective analysis.

Department of Psychiatry, University of Pittsburgh Medical Center, Western Psychiatric Hospital, University of Pittsburgh School of Medicine, Pittsburgh, PA, USA.
Article Synopsis
- - The study aimed to find out if mood episodes (depression and mania) in young people with Bipolar Spectrum Disorder vary by latitude and seasons.
- - Researchers evaluated mood in 413 participants over nearly 92 months, finding that depressive episodes were more frequent in winter, while manic episodes were more common in summer.
- - The findings suggest the need for strategies to manage the seasonal impacts on mood for individuals with Bipolar Disorder, especially recognizing the differences across various locations.

Article Synopsis
- - Dopamine (DA) is a key neurotransmitter linked to brain function, and its signaling changes are associated with neuropsychiatric disorders like bipolar disorder (BD), which involves mood swings between mania and depression.
- - The drug GBR 12909 is used in research to inhibit DA reuptake, creating experimental conditions that model BD-like behaviors, especially in zebrafish, which are recognized as valuable for studying neurobehavioral changes.
- - The study evaluates GBR 12909's effectiveness in mimicking BD symptoms in zebrafish, emphasizing the role of dopamine transporters and discussing the benefits and challenges of using zebrafish for broader BD research.
Copy number variations in RNF216 and postsynaptic membrane-associated genes are associated with bipolar disorder: a case-control study in the Japanese population.
Psychiatry Clin Neurosci
January 2025
Pathophysiology of Mental Disorders, Nagoya University Graduate School of Medicine, Nagoya, Japan.
Article Synopsis
- - The study investigates the link between rare copy number variations (CNVs) in synaptic genes and bipolar disorder (BD) in a Japanese population, using genome hybridization techniques on nearly 2,000 BD patients and 2,760 controls.
- - Results indicate a strong association between the RNF216 gene and BD, with significant findings also related to postsynaptic membrane components, suggesting these genetic factors contribute to BD risk.
- - The findings enhance understanding of BD's genetic underpinnings, highlighting the importance of CNVs in gene regions that may influence the disorder's development.
Efficacy and Safety of Ketamine/Esketamine in Bipolar Depression in a Clinical Setting.
J Clin Psychiatry
October 2024
Yale Depression Research Program, Department of Psychiatry at the Yale School of Medicine and the Yale Psychiatric Hospital, New Haven, Connecticut.
Bipolar disorder represents a significant source of morbidity and elevated mortality risk. Ketamine has emerged as a powerful antidepressant; however, there have been few trials of ketamine in bipolar depression and no trials with esketamine in bipolar depression, and few data exist from real-world settings. Here, we report outcomes from a cohort of patients with bipolar depression treated with ketamine/ esketamine in a real-world setting.
