Druggable Transcriptional Networks in the Human Neurogenic Epigenome.

Druggable Transcriptional Networks in the Human Neurogenic Epigenome. Pharmacol Rev. 2019 Oct;71(4):520-538 Authors: Higgins GA, Williams AM, Ade AS, Alam HB, Athey BD Abstract Chromosome conformation capture methods have revealed the dynamics of genome architecture which is spatially organized into topologically associated domains, with gene regulation mediated by enhancer-promoter pairs in chromatin space. New evidence shows that endogenous hormones and several xenobiotics act within circumscribed topological domains of the spatial genome, impacting subsets of the chromatin contacts of enhancer-gene promoter pairs in cis and trans Results from the National Institutes of Health-funded PsychENCODE project and the study of chromatin remodeling complexes have converged to provide a clearer understanding of the organization of the neurogenic epigenome in humans. Neuropsychiatric diseases, including schizophrenia, bipolar spectrum disorder, autism spectrum disorder, attention deficit hyperactivity disorder, and other neuropsychiatric disorders are significantly associated with mutations in neurogenic transcriptional networks. In this review, we have reanalyzed the results from publications of the PsychENCODE Consortium using pharmacoinformatics network analysis to better understand druggable targets that control neurogenic transcriptional networks. We found that valproic acid and other psychotropic drugs directly alter these networks, including chromatin rem...

Reported prevalences of co-occurring mental health or psychiatric conditions in people with autism range widely. Improved prevalence estimates and identification of moderators are needed to enhance recognition and care, and to guide future research.MethodsIn this systematic review and meta-analysis...

CONCLUSIONS: We obtained novel evidence for shared biological mechanisms that act across psychiatric disorders and we showed that several gene sets that have been related to individual disorders play a role in a broader range of psychiatric disorders.

CONCLUSIONS: Our results suggest a causal role of insomnia in autism spectrum disorder and bipolar disorder. Future disease models should include insomnia as a factor for these two disorders to develop effective interventions. More detailed mechanism studies may also be inspired by this causal inference.

In conclusion, this review highlights the importance for clinicians to investigate for the presence of chronic nightmares along with other sleep difficulties (most commonly, insomnia and sleep apnea), to consider the potential influence of nightmares on the course of the primary mental disorder, and to be prepared to grant access to treatments targeting nightmares.

Globally, psychiatric disorders, such as anxiety disorder, bipolar disorder, schizophrenia, depression, autism spectrum disorder and attention-deficit/hyperactivity disorder (ADHD) are becoming more prevalent. Although the exact pathological alterations are not yet clear, recent studies have demonstrated that widespread changes of very complex metabolic pathways may partially underlie the pathophysiology of many psychiatric diseases. Thus, more attention should be directed to metabolic-based therapeutic interventions in the treatment of psychiatric disorders. Emerging evidence from numerous studies suggests that administra...

Conclusion: Paliperidone has some dynamic and kinetic superiority to the parent drug risperidone. Nonetheless, larger rigorous studies would define the real place of the atypical antipsychotic paliperidone in child and adolescent psychiatry. Until then, risperidone with its long track record in CAP population would remain a first option though.Pharmacology 2019;104:67 –70

DISCUSSION: These results show that ADHD coaggregated with other major psychiatric disorders, specifically schizophrenia, bipolar disorder, major depressive disorder, and ASD, within families. The results suggest that public health officials and psychiatrists should closely monitor and follow the mental health of FDRs of ADHD-diagnosed individuals, such as parents and siblings of children with ADHD.

Computerized device uses (CDU; e.g., playing computer games (CompGaming), mobile phone use (minutes/week for the last three months (PhoneUse) and total usage years), hands-free/speakerphone device use). Epidemiological associations between CDUs and psychiatric disorders are frequently reported; the biological mechanisms underlying these observations remain unknown. We investigated genetic overlap and causality between CDUs and psychiatric disorders (attention deficit hyperactivity disorder (ADHD), schizophrenia (SCZ), autism spectrum disorder, major depressive disorder, alcohol dependence, bipolar disorder, anorexia nervos...

Conclusion: Fun seeking on the BAS and frustration intolerance should be considered as targets in prevention and intervention programs for IA among adolescents with ADHD.IntroductionThe negative effects of internet addiction (IA) have become a concern in the past decades. IA is characterized by persistent internet use despite negative consequences, loss of control, preoccupation with internet use, increasing amounts of time spent online, and withdrawal symptoms (1). Internet gaming disorders are listed in the “Conditions for Further Study” section in the Fifth Edition of Diagnostic and Statistical Manual of Men...
