Many of the same genes that  influence our personality also affect our mental health

By Christian Jarrett We know from twin and family studies that our personality is to a large degree – probably around 40 per cent – inherited. Geneticists are busy trying to find the specific gene variants involved, but because each one on its own only exerts a modest influence, this is challenging research requiring huge samples. A new study in Nature Genetics has made a significant contribution, using the technique of Genome Wide Analysis to look for genetic variants that correlate with personality. The researchers led by Min-Tzu Lo at the University of California, San Diego have identified variations in six genetic loci that correlate with different personality trait scores, five of which were previously unknown. In a separate analysis, the researchers also showed that many of the genetic variants involved in personality overlap with those involved in the risk of developing mental health disorders. The researchers analysed the genomes of hundreds of thousands of people, including clients of 23andMe – a commercial service that promises to inform customers about their ancestry and health based on their DNA (usefully for present purposes, the company also asks its clients to complete personality questionnaires). Among the genetic loci the researchers identified as being linked with personality, the most influential correlated with Neuroticism scores and was on a region of chromosome 8 (specifically 8p23.1) t...

Authors: Geoffroy PA, Micoulaud Franchi JA, Lopez R, Schroder CM, membres du consensus Mélatonine SFRMS Abstract Melatonin is a hormone secreted by the pineal gland at night. This hormone has many physiological functions, the main one being to synchronise individuals' biological rhythms. Exogenous melatonin has the same chronobiotic action, even at small doses (0.125mg). In addition, a sleep-inducing (soporific) action appears to occur in a dose-effect relationship, i.e. as the dose increases. In psychiatric disorders, these two effects could have interesting applications in clinical practice. The French ins...

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.

CONCLUSIONS: Half of those who died by suicide had at least one diagnosed mental health condition in the year before death, and most mental health conditions were associated with an increased risk of suicide. Findings suggest the importance of suicide screening and providing an approach to improve awareness of mental health conditions. PMID: 31185853 [PubMed - as supplied by publisher]

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...

We reported DEGs with a nominal p-value of 0.8. The network construction was created using blockwiseModules function for consideration of computer efficiency. The module detection criteria were as follows: minimum module size of 50, deepsplit of 4, and merge threshold of 0.25. The merged modules were then summarized with module eigengene (ME) correlations>0.75. MEs were defined by their first principal component and were labeled with different colors as module names in the Results section. After the modules were generated, we conducted different enrichment analysis to explore the functional interpretation of genes withi...
