Individuals with bipolar disorder (BD) require chronic pharmacotherapy, typically including medication switches or polypharmacy due to persisting symptoms or intolerable side effects. Here, we quantified pharmacotherapy exposure (PE) of Mayo Clinic BD Biobank participants using the number of cross-sectional (at enrollment) and lifetime BD-specific medications and medication classes, to understand the relationship between PE and markers of disease severity or treatment failure, psychiatric comorbidities, and polygenic risk scores (PRS) for six major psychiatric disorders...

Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent psychiatric disorders that affects children and even continues into adulthood. Dexmedetomidine (DEX), a short-term sedative, can selectively activate the α2-adrenoceptor. Treatment with α2-adrenergic agonists in patients with ADHD is becoming increasingly common. However, the therapeutic potential of DEX for the treatment of ADHD is unknown. Here, we evaluated the effect of DEX on ADHD-like behavior in spontaneously hypertensive rats (SHRs), a widely used animal model of ADHD...

Cannabis use is associated with increased severity of psychotic symptoms and the risk of acute agitation and aggressive behavior in inpatient (IP) and outpatient settings. Whether or not cannabis use is associated with increased acuity of psychosis-related ED presentations and risk of repeat ED visits for psychosis is unclear. In this retrospective study of 2,134 ED visits for acute psychosis, we investigated the risk of physical restraint, parenteral medication administration, psychiatric hospitalization, and recurrent ED visits...

Developmental language disorder (DLD) is characterized by enduring low language abilities with a significant functional impact, in the absence of biomedical conditions in which language impairment is part of a complex of impairments. There is a lack of awareness of DLD even among healthcare professionals. Here we estimated the prevalence of DLD and its links to reading and learning difficulties and physical and mental health in the Danish Blood Donor Study (N = 46,547), where DLD-related information is based on questionnaires (self-report)...

Emerging research suggests suicidality may have increased during the COVID-19 pandemic. This cross-sectional study aimed to advance understanding of suicide risk during the pandemic through novel use of a large insurance database. Using logistic regression across time-points, we estimated the effect of exposure to SARS-CoV-2 infection on rates of suicidal ideation and suicide attempts in infected individuals versus uninfected controls during the pandemic (March 2020 - September 2021). In uninfected individuals, we estimated the effect of exposure to the pandemic period versus the pre-pandemic control period (January 2017 to February 2020) on suicidality rates...

OBJECTIVE: Minimal guidance is available in the literature to develop protocols for training non-clinician raters to administer semi-structured psychiatric interviews in large, multi-site studies. Previous work has not produced standardized methods for maintaining rater quality control or estimating interrater reliability (IRR) in such studies. Our objective is to describe the multi-site Texas Childhood Trauma Research Network (TX-CTRN) rater training protocol and activities used to maintain rater calibration and evaluate protocol effectiveness...

Traumatic events play a key role in the development and course of psychosis. Psychotic symptoms themselves and coercive treatment practices can be inherently traumatic. Hence, reliable and valid methods of assessing trauma and its impact (i.e., Post-Traumatic Stress Disorder (PTSD) symptomology) are essential for use with people with psychosis. Many measures are available to select from, but this is the first review to appraise the psychometric properties of trauma measures to guide decision making regarding instrument use...

In treatment studies of depression, response is typically defined as a 50% or greater reduction in symptom severity. However, multiple surveys of depressed patients have found that patients prioritize improved functioning and quality of life objectives over symptom improvement as the most important goal of treatment. The goal of the present study is to widen the lens of assessing outcome by examining response in nonsymptom domains in patients who are, by convention, considered nonresponders to treatment. Eight hundred and forty-four patients with major depressive disorder completed the Remission from Depression Questionnaire (RDQ), a self-report measure that assesses multiple constructs considered by patients to be relevant to assessing treatment outcome...

Strong evidence exists based on metanalysis of the relationship between toxoplasmosis and many psychiatric diseases: schizophrenia, bipolar disorder, and suicidal behavior. Herein, we estimate the number of cases based on the attributable fraction due to toxoplasmosis on these diseases. The population attributable fraction of mental disease associated with toxoplasmosis was 20,4% for schizophrenia; 27,3% for bipolar disorder; and 0,29% for suicidal behavior (self-harm). The lower and upper estimated number of people with mental disease associated with toxoplasmosis was 4'816...

Early auditory processing (EAP) deficits are prevalent in schizophrenia and linked to disturbances in higher order cognition and daily functioning. Treatments that target EAP have the potential to drive downstream cognitive and functional improvements, but clinically feasible means to detect EAP impairment are lacking. This report describes the clinical feasibility and utility of using the Tone Matching (TM) Test to assess EAP in adults with schizophrenia. Clinicians were trained to administer the TM Test as part of a baseline cognitive battery to inform choice of cognitive remediation (CR) exercises...

It is unknown how smoking behavior polygenic scores (PRS) relate to psychosis and psychotic symptoms. To elucidate this, genotype and phenotype data were collected from patients with schizophrenia, their unaffected siblings, and healthy controls in a six-year follow-up prospective cohort study. Associations between smoking behaviors, PRS and schizophrenia symptoms were explored using linear mixed-effect models. The mean number of cigarettes smoked per day were 18 for patients, 13 for siblings and 12 for controls...

Suicidal behaviors are common among patients with substance use disorders (SUD). However, the prevalence and clinical factors related to suicide behaviors among patients who have had substance-induced psychosis (SIP) is unknown. This study aims to explore the prevalence, clinical features, and factors related to lifetime suicidal ideation (SI) and suicide attempts (SA) in patients who have had SIP across their lifetime. A cross-sectional study was conducted in an outpatient center for addiction treatment between 01/01/2010 and 12/31/2021...

Processing of basic auditory features, one of the earliest stages of auditory perception, has been the focus of considerable investigations in schizophrenia. Although numerous studies have shown abnormalities in pitch perception in schizophrenia, other basic auditory features such as intensity, duration, and sound localization have been less explored. Additionally, the relationship between basic auditory features and symptom severity shows inconsistent results, preventing concrete conclusions. Our aim was to present a comprehensive overview of basic auditory processing in schizophrenia and its relationship with symptoms...

The COVID-19 pandemic has caused a high burden in the general population. The exposure to an accumulation of risk factors, as opposed to a single risk, may have been associated with higher levels of depressive and anxiety symptoms during the pandemic. This study aimed to (1) identify subgroups of individuals with distinct constellations of risk factors during the COVID-19 pandemic and (2) investigate differences in levels of depressive and anxiety symptoms. German participants (N = 2245) were recruited between June-September 2020 through an online survey (ADJUST study)...

Borderline personality disorder (BPD) has high rates of comorbidity with mood disorders, including treatment-resistant depression (TRD). Comorbidity of BPD with depression is associated with poorer response to antidepressants. Intravenous ketamine is a novel treatment for TRD that has not been specifically evaluated in patients with comorbid BPD. In this retrospective analysis of data collected from participants who received care at the Canadian Rapid Treatment Centre of Excellence (CRTCE; Braxia Health; ClinicalTrials...

Direct-to-consumer DNA tests provide information on ancestry and family relations. Their increased use in recent years has led many to discover that their presumed father is not their biological father, a non-paternity event (NPE). We aimed to explore and quantify the psychiatric effects of discovering one's father's identity was misattributed. We distributed questionnaires in a private online community of individuals who learned they were NPEs. Questionnaires included clinical scales assessing depressive, anxiety, and panic symptomatology as well as background and personal details regarding participants' NPE discovery and demography...
