Functional coupling of M1 muscarinic acetylcholine receptor to Gαq/11 in dorsolateral prefrontal cortex from patients with psychiatric disorders: a postmortem study. Eur Arch Psychiatry Clin Neurosci. 2019 Dec 05;: Authors: Odagaki Y, Kinoshita M, Meana JJ, Callado LF, García-Sevilla JA Abstract Accumulating studies have implicated intracellular signaling through muscarinic acetylcholine receptors (mAChRs) in psychiatric illness. In the present study, carbamylcholine chloride (carbachol)-induced Gαi/o and Gαq/11 activation was identified in postmortem human prefrontal cortical ...

ConclusionsRumination is known to be associated with poor prognosis in mental health. This study suggests that rumination is a maladaptive coping style associated not only with worry, distress and illness severity, but also with socioeconomic status. Also, rumination demonstrated a specific association with panic disorder.

Publication date: Available online 7 December 2019Source: Progress in NeurobiologyAuthor(s): M.M.J. van den Berg, J. Krauskopf, J.G. Ramaekers, J.C.S. Kleinjans, J. Prickaerts, J.J. BriedéAbstractCirculating microRNAs (cimiRNAs) are a class of non-encoding RNAs found in bodily fluids such as blood, cerebrospinal fluid (CSF) and tears. CimiRNAs have been implicated as promising biomarkers for central nervous system (CNS) disorders because they are actively secreted as messengers and are profoundly involved in fine-tuning of developmental and differentiation processes. Furthermore, they are attractive biomarkers becau...

AbstractMajor psychiatric traits are genetically inter-correlated with one another, but it not well known which genes play pleiotropic effects across different traits. We curated and compared genes identified from large-scale genome-wide association studies for seven psychiatric traits, including depression, bipolar disorder, schizophrenia, autism spectrum disorder, attention-deficit/hyperactivity disorder, anxiety and neuroticism. We then explored biological functions of the top pleiotropic genes. A total of 243 cross-trait genes were identified for the seven traits. Except for autism spectrum disorder, there was signific...

Almost half (48%) of children and adolescents with a psychotic disorder said they recently had suicidal thoughts or had in the past considered death by suicide when interviewed in the emergency department (ED) using a brief screening questionnaire, according to areport published this week inPsychiatric Services. Most of these youth did not report a chief complaint related to suicidal ideation or behavior when arriving at the ED.Notably, half of the children and adolescents who screened positive for suicide using the Ask Suicide-Screening Questions (ASQ) screen were discharged from the ED, including 44% of those who reporte...

Authors: Pershad Y, Guo M, Altman RB Abstract One in five Americans experience mental illness, and roughly 75% of psychiatric prescriptions do not successfully treat the patient's condition. Extensive evidence implicates genetic factors and signaling disruption in the pathophysiology of these diseases. Changes in transcription often underlie this molecular pathway dysregulation; individual patient transcriptional data can improve the efficacy of diagnosis and treatment. Recent large-scale genomic studies have uncovered shared genetic modules across multiple psychiatric disorders - providing an opportunity for an in...

AbstractAccumulating studies have implicated intracellular signaling through muscarinic acetylcholine receptors (mAChRs) in psychiatric illness. In the present study, carbamylcholine chloride (carbachol)-induced G αi/o and G αq/11 activation was identified in postmortem human prefrontal cortical membranes. The following two sample cohorts were used: subjects [1], consisting of 40 controls without neuropsychiatric disorders, and subjects [2], consisting of 20 with bipolar disorder (BP), 20 major depressive disorder (MDD), 20 schizophrenia, and 20 controls, strictly sex- and age-matched. Carbachol-stimulated [35S...

Am I an Alcoholic? Alcoholism (also known as Alcohol Use Disorder, or AUD) is a chronic, relapsing disease affecting millions of individuals in the United States. According to the 2017 National Survey on Drug Use and Health (NSDUH), 51 percent of the population aged 12 and older reported binge drinking in the past month. More than 14 million individuals aged 12 and older were suffering from alcoholism. And each year, more than 2,200 individuals die due to alcohol poisoning. Many may come to wonder, “Am I an alcoholic?” What Causes Alcoholism? Some individuals are more prone to alcoholism than others. Alcoholism...

Discussion: The data in the literature about these drugs use for schizophrenia treatment is still limited and have great heterogeneity. Thus, assay with greater robustness are needed to assess real benefits of these drugs as adjuvant therapy.
