Association analysis of genes in serotonin pathway with attention and executive function in patients with bipolar affective disorder

The reason why it is difficult to identify susceptibility genes attributed to bipolar disorder (BPD) is the phenotypic heterogeneity. The use of endophenotypes has been advocated as one possible strategy to discovery cause variants of BPD.

Authors: Silveira C, Guedes R, Maia D, Curral R, Coelho R Abstract Multiple Sclerosis (MS) is a chronic disabling neuroinflammatory disease. Psychiatric manifestations have a high prevalence in MS patients and may worsen the illness progression and the patients' quality of life (QoL). Depression is a highly prevalent condition in MS patients, associated with poorer adherence to treatment, decreased functional status and QoL, and increased suicide risk. Diagnosis and treatment of this disorder is challenging because of symptom overlap. Other prevalent psychiatric comorbidities are anxiety disorders, bipolar disorder...

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.

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...

This week’s Psychology Around the Net takes a look at what to do if you think your child is at risk for mental illness, why self-regulation is so important for people with ADHD, the symptoms of problematic smartphone use, and the mental and physical fatigue that often accompanies chronic illness, and more.     Does Mental Illness Run in Families?: What should you do if you suspect your child is at risk of developing a mental disorder — especially when mental illness runs in your family? According to psychologist Scott Bea PsyD, an important first step is helping your child build resilience, a persona...

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...

ConclusionThis study allowed us, by removing the entire septum as a whole structure, to redefine the concept of the septum as a complex structure based on islands of muscle fibers irregularly arranged in vertex, in a context of collagen tissue, similar to the structure of myomas. It appears to deeply involve the anterior and posterior uterine wall, resembling a “reverse letter H”.

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...

Ansary, Asuka Ito, Naoko Tanaka, Hiroshi Kinoshita, Yasushi Kishimoto, Tohru YamamotoAbstractMDGA1 (MAM domain-containing glycosylphosphatidylinositol anchor) has recently been linked to schizophrenia and bipolar disorder. Dysregulation of dopamine (DA) and serotonin (5-HT) systems has long been associated with schizophrenia and other neuropsychiatric disorders. Here, we measured prepulse inhibition (PPI) of the startle response and ex viv...

Sanchez Vega, Michael Piper, Thomas H.J. Burne, Lachlan A. Jolly, Stephen A. Wood, Peter PenzesSummaryVariants in the ANK3 gene encoding ankyrin-G are associated with neurodevelopmental disorders, including intellectual disability, autism, schizophrenia, and bipolar disorder. However, no upstream regulators of ankyrin-G at synapses are known. Here, we show that ankyrin-G interacts with Usp9X, a neurodevelopmental-disorder-assoc...
