Objectives: The taxonic versus dimensional status of mood symptoms has been the subject of debate among mental health professionals. Conventional diagnostic models suggest that mood disorders are categorical; however, the inability of categorical models to adequately account for subthreshold unipolar and bipolar presentations and the heterotypic continuity of symptoms in unipolar and bipolar cases has resulted in growing support for dimensional views. The current study sought to evaluate the relative viabilities of categorical and dimensional models of mood symptoms within a taxometric framework.
Methods: We examined the latent structure of mood symptoms in an epidemiological sample drawn from the Collaborative Psychiatric Epidemiological Surveys. Using three taxometric procedures (MAMBAC, MAXEIG, and L-Mode), we analyzed indicators of mania and depression created from the mood symptoms section of the survey.
Results: The taxometric analyses supported a taxonic rather than dimensional structure for mania and depression. Membership in the mania and depressive taxa was associated with meeting criteria for DSM-IV lifetime manic episode and major depressive disorder, respectively. We identified a subset of 700 individuals falling into both taxa; membership in this subset was associated with lifetime bipolar disorder status. Group membership predicted designated external variables including help-seeking, family history, and duration of impairment. Within taxon and/or complement groups, severity scores still appeared to predict external variables.
Conclusion: Our findings suggest that although taxonic, mood disorders possess meaningful dimensional variation.

Background: Pregnancy-related anatomic, physiologic, and hormonal factors can occur at different stages of pregnancy and affect sleep disturbances. The relationship between sleep problems during pregnancy and postpartum depressive symptoms as well as neonatal condition at delivery have not been well described. This study hypothesized that sleep problems are associated with postpartum depressive symptoms and adverse neonatal outcomes at delivery.

Background: Studies regarding hypercoagulation in Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) patients have produced conflicting results. With a presumption that the early coagulation phase may affect the occurrence of NAION, this study aims to investigate the early coagulation markers, E-selectin and P-selectin, to determine whether these biomolecular changes play a significant role in NAION, thus potentially leading to a better clinical approach.
Methods: A cross-sectional study involving two groups of NAION subjects, a hypercoagulation group and a non-hypercoagulation group, was conducted in the Neuro-Ophthalmology Division, Department of Ophthalmology, FKUI-RSCM Kirana from October 2020 to April 2022.
Challenges in the Diagnosis and Management of Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD).

Myelin oligodendrocyte glycoprotein antibody-associated disease has been recently identified to be a distinct autoimmune central nervous system disorder. There is significant clinical and radiological overlap with multiple sclerosis and aquaporin-4-IgG-associated neuromyelitis optica spectrum disorders. Clinical course is variable in that patients may have a monophasic or relapsing course, disease severity is unpredictable, and unlike other idiopathic autoimmune inflammatory disorders, there is no gender predilection and it is more likely to affect pediatric population.

Traumatic brain injury (TBI) is a burdensome condition frequently associated with an increased risk of psychiatric disorders. Although the exact molecular signaling pathways have not yet been fully defined, the compromised integrity of functional brain networks in regions such as the prefrontal cortex and anterior cingulate cortex has been linked to persistent symptoms, including depression, fatigue, and sleep disorders. Understanding how TBI affects neural physiology enables the development of effective interventions.
