Summary: The cognitive effects of tobacco use among women with schizophrenia, bipolar disorder, or depression have not been extensively studied. However, a study found that female tobacco users in these groups demonstrated poorer cognitive functioning and smoking may exacerbate cognitive dysfunction associated with major mental illnesses among women.

Summary: The study found that cilia genes play an important role in the pathogenesis of psychiatric disorders, with dysfunction potentially contributing to multiple disorders. Notably, cilia GPCRs genes and transition zone proteins were particularly affected in schizophrenia. This research provides new insights into the pathophysiology of these disorders.

Summary: This study found that PACAP may play an important role in the pathophysiology of mood disorders. The expression of PACAP in the hypothalamic PVN was related to mood disorders and correlated with the emotional status of patients with major depressive disorder, bipolar disorder, and Alzheimer's disease. Additionally, alterations in mRNA expression of PACAP and its receptors in target regions such as the DLPFC and ACC were associated with different types of mood disorders, suicide, and psychotic features.

Summary: This study systematically reviews the clinical features and therapeutic evidence regarding manic syndromes in different types of dementia. The results indicate that manic symptoms are associated with disease progression in Alzheimer's disease, have a variable relationship with cognitive decline in vascular dementia, and often precede or coincide with cognitive impairment in frontotemporal dementia. Mood stabilizers and electroconvulsive therapy appear to be the most effective treatments, while the benefits of short-term treatment with antipsychotic agents need to be balanced with associated risks. Importantly, low-dose lithium salts may have neuroprotective activity in patients with Alzheimer's disease.

Summary: Migraine shows a certain level of shared genetic basis with bipolar disorder, depression, and schizophrenia, with some shared genetic loci. It is less polygenic compared to mental disorders and shares variants with intelligence and educational attainment. Specific loci were identified that are jointly associated with migraine and depression, as well as with migraine and schizophrenia, implicating shared molecular mechanisms and highlighting candidate migraine genes for further research.

Summary: This study found that levels of circulating neuropeptides were significantly decreased in patients with schizophrenia, bipolar disorder, and major depressive disorder compared to healthy controls. Neurotensin performed the best in differentiating patient groups from controls. Neurotensin levels were associated with cognitive function and psychotic symptoms. These findings provide potential treatment targets for improving clinical symptoms and cognitive function in these severe mental illnesses.

Summary: This study investigates the familial aggregation and shared genetic loading between common psychiatric disorders (such as schizophrenia, major depressive disorder, and bipolar disorder) and type 2 diabetes. The results suggest a familial association between type 2 diabetes and the psychiatric disorders studied, as well as a shared genetic etiology between major depressive disorder and type 2 diabetes.

Summary: The study found that first-degree relatives of patients with obsessive-compulsive disorder have a higher risk of major psychiatric disorders such as major depressive disorder, bipolar disorder, OCD, autism spectrum disorder, ADHD, and schizophrenia. Different familial relationships of first-degree relatives consistently had increased risks for these disorders, and a dose-dependent relationship was found between the number of OCD probands and the risk of each major psychiatric disorder.

Summary: Schizophrenia, bipolar disorder, and major depressive disorder are the most common psychiatric disorders. Diagnosing these disorders is difficult due to overlaps in genetic epidemiology and molecular genetics. This study used transcriptomic data to identify key genes and construct a classification model for differentiating these disorders. The model showed potential for improving the diagnoses of these psychiatric disorders.

Summary: Oxidative stress refers to the persistent imbalance between the activity of toxic reactive forms of oxygen and nitrogen and the antioxidant defense. The brain is highly susceptible to oxidative imbalance due to its lipid-rich structure, high oxygen consumption, and lack of sufficient antioxidant protection. Oxidative stress has been linked to various psychiatric disorders and is characterized by behavioral, emotional, and cognitive abnormalities as well as significant impairment in social life.

Summary: Major psychiatric disorders, such as major depressive disorder, bipolar disorder, and schizophrenia, are a significant public health burden. The search for biomarkers has been a leading focus in biological psychiatry, with cross-scale and multi-omics approaches contributing to the understanding of gene-related pathogenesis and the exploration of potential biomarkers. This article summarizes the results of using combined transcriptomics and magnetic resonance imaging to study brain changes associated with major psychiatric disorders, revealing neurobiological mechanisms and offering new avenues for the development of objective biomarkers and clinical indicators.

Summary: Depression is one of the most common mental diseases, but its understanding is insufficient. The relationship between carnitine and depression has been confirmed in multiple studies, and the level of acylcarnitines can serve as biomarkers for depression, while supplementing acetyl-L-carnitine is beneficial for the treatment of depression.

Summary: This study investigated whether parents of adolescents with major depressive disorder (MDD) were more likely to have MDD, bipolar disorder (BD), schizophrenia (SZ), alcohol use disorder, or substance use disorder compared to parents of adolescents without MDD. The study also explored whether the response to antidepressant treatment predicted the likelihood of parental psychiatric disorders. The results showed that parents of adolescents with MDD had a higher prevalence of MDD, BD, SZ, alcohol use disorder, or substance use disorder. The response to antidepressant treatment and the parent's sex were found to influence the within-disorder transmission of MDD.

Summary: Higher levels of neurofilament light chain and proinflammatory cytokines were observed in patients with bipolar disorder and major depressive disorder. The bone turnover biomarker, P1NP, was related to MDD. The association among the brain-bone axis, systemic inflammation, and cognitive function remains unclear in severe affective disorders.

Summary: The aim of this study was to analyze whether specific genes related to inflammatory processes and VEGF were associated with treatment response to low-dose ketamine in patients with treatment-resistant depression. The findings revealed that specific single nucleotide polymorphisms in IL1R1 and VEGFC were related to the rapid antidepressant effect, while single nucleotide polymorphisms in PIGF and TNFRSF8 were associated with the sustained antidepressant effect. The synergic modulation of inflammatory and VEGF systems may contribute to the antidepressant effect of ketamine.

Summary: Studies have shown that there is a positive relationship between resistance to antidepressants and the progression of bipolar disorder. However, the specific influence of different types of antidepressants, such as SSRIs and SNRIs, in this context has not been thoroughly investigated. This study recruited a total of 5,285 young people with antidepressant-resistant depression and 21,140 with antidepressant-responsive depression. It was found that those with resistance to antidepressants, especially to both SSRIs and SNRIs, were at an increased risk of developing bipolar disorder.
