Major depressive disorder (MDD) is a complex neuropsychiatric disorder potentially influenced by factors such as stress and inflammation. Chronic stress can lead to maladaptive brain changes that may trigger immune hyperactivation, contributing to MDD's pathogenesis. While the involvement of inflammation in MDD is well established, the effects of inflammatory preconditioning in animals subsequently exposed to chronic stress remain unclear. ⋯ A trend toward elevated IL-17 levels was also observed at the peripheral level. These findings indicate that inflammatory preconditioning contributes significantly to behaviors phenotypically associated with MDD. Furthermore, the study suggests that these behavioral changes are linked to a dysfunctional immune response and impaired neuroplasticity.

Studies have revealed a comorbidity to be common between patients with migraine and those with psychiatric disorders, such as bipolar disorder (BD) and major depressive disorder (MDD). However, considering the substantial epidemiological differences in the prevalence of migraine between Western and Asian countries, further investigation was required to determine whether findings regarding familial coaggregation of migraine and psychiatric disorders can be generalized to Asian populations. Using the Taiwan National Health Insurance Database, we included 822,773 first-degree relatives (FDRs) of individuals with migraine and 3,291,092 FDRs of individuals without migraine. ⋯ Thus, clinicians should closely monitor the mental health of FDRs of individuals with migraine. PERSPECTIVE: First-degree relatives of migraine probands had an increased risk of being diagnosed with psychiatric disorders, including schizophrenia, bipolar disorder, major depressive disorder, anxiety disorders, and alcohol or substance use disorders. They also died by suicide, regardless of the individual migraine and psychiatric comorbidities.

The diagnosis and analysis of major depressive disorder (MDD) faces some intractable challenges such as dataset limitations and clinical variability. Resting-state functional magnetic resonance imaging (Rs-fMRI) can reflect the fluctuation data of brain activity in a resting state, which can find the interrelationships, functional connections, and network characteristics among brain regions of the patients. In this paper, a brain functional connectivity matrix is constructed using Pearson correlation based on the characteristics of multi-site Rs-fMRI data and brain atlas, and an adaptive propagation operator graph convolutional network (APO-GCN) model is designed. ⋯ The experimental results on Rs-fMRI data from 1601 participants (830 MDD and 771 HC) and 16 sites of REST-meta-MDD project show that the APO-GCN achieved a classification accuracy of 91.8%, outperforming those of the state-of-the-art classifier methods. The classification process is driven by multiple significant brain regions, and our method further reveals functional connectivity abnormalities between these brain regions, which are important biomarkers of classification. It is worth noting that the brain regions identified by the classifier and the networks involved are consistent with existing research results, which suggest that the pathogenesis of depression may be related to dysfunction of multiple brain networks.

Randomized Controlled Trial Multicenter StudyVirtual Reality-Based Cognitive Behavior Therapy for Major Depressive Disorder: An Alternative to Pharmacotherapy for Reducing Suicidality.
Cognitive behavioral therapy (CBT) has long been recognized as an effective treatment for depression and suicidality. Virtual reality (VR) technology is widely used for cognitive training for conditions such as anxiety disorder and post-traumatic stress disorder, but little research has considered VR-based CBT for depressive symptoms and suicidality. We tested the effectiveness and safety of a VR-based CBT program for depressive disorders. ⋯ VR CBT treatment for major depressive disorder has the potential to be equivalent to the gold-standard pharmacotherapy in reducing depressive symptoms, suicidality, and related clinical symptoms, with no difference in improvement found in this study. Thus, VR-based CBT might be an effective alternative to pharmacotherapy for depressive disorders.

Randomized Controlled Trial
Effectiveness of app-based cognitive behavioral therapy for insomnia on preventing major depressive disorder in youth with insomnia and subclinical depression: A randomized clinical trial.
Increasing evidence suggests that insomnia plays an important role in the development of depression, supporting insomnia intervention as a promising approach to prevent depression in youth. This randomized controlled trial evaluated the effectiveness of app-based cognitive behavioral therapy for insomnia (CBT-I) in preventing future onset of major depressive disorder (MDD) in youth. ⋯ App-based CBT-I is effective in preventing future onset of major depression and improving insomnia outcomes among youth with insomnia and subclinical depression. These findings highlight the importance of targeting insomnia to prevent the onset of MDD and emphasize the need for wider dissemination of digital CBT-I to promote sleep and mental health in the youth population.
