Brainwide Anatomical Connectivity and Prediction of Longitudinal Outcomes in Antipsychotic-Naïve First-Episode Psychosis.

Background: Disruptions of axonal connectivity are thought to be a core pathophysiological feature of psychotic illness, but whether they are present early in the illness, prior to antipsychotic exposure, and whether they can predict clinical outcome remain unknown.

Methods: We acquired diffusion-weighted magnetic resonance images to map structural connectivity between each pair of 319 parcellated brain regions in 61 antipsychotic-naïve individuals with first-episode psychosis (15-25 years, 46% female) and a demographically matched sample of 27 control participants. Clinical follow-up data were also acquired in patients 3 and 12 months after the scan.

Validating cognitive screening in young people with first-episode psychosis: The CogScreen protocol.

Aim: Cognitive impairments are a core feature of first-episode psychosis (FEP) and one of the strongest predictors of long-term psychosocial functioning. Cognition should be assessed and treated as part of routine clinical care for FEP. Cognitive screening offers the opportunity to rapidly identify and triage those in most need of cognitive support.

An open label pilot trial of low-dose lithium for young people at ultra-high risk for psychosis.

Aim: Lithium, even at low doses, appears to offer neuroprotection against a wide variety of insults. In this controlled pilot, we examined the safety (i.e.

Social disadvantage in early psychosis and its effect on clinical presentation and service access, engagement and use.

Incidence of psychosis varies geographically due to factors such as social disadvantage. Whether this influences the clinical presentation and/or engagement of those experiencing psychosis remains relatively understudied. This study analysed data from young people across Australia accessing ultra-high risk (UHR) or first episode psychosis (FEP) services delivered through the headspace Early Psychosis (hEP) program between June 2017 and March 2021.

Effects of risperidone/paliperidone versus placebo on cognitive functioning over the first 6 months of treatment for psychotic disorder: secondary analysis of a triple-blind randomised clinical trial.

The drivers of cognitive change following first-episode psychosis remain poorly understood. Evidence regarding the role of antipsychotic medication is primarily based on naturalistic studies or clinical trials without a placebo arm, making it difficult to disentangle illness from medication effects. A secondary analysis of a randomised, triple-blind, placebo-controlled trial, where antipsychotic-naive patients with first-episode psychotic disorder were allocated to receive risperidone/paliperidone or matched placebo plus intensive psychosocial therapy for 6 months was conducted.

Gradients of striatal function in antipsychotic-free first-episode psychosis and schizotypy.

Both psychotic illness and subclinical psychosis-like experiences (PLEs) have been associated with cortico-striatal dysfunction. This work has largely relied on a discrete parcellation of the striatum into distinct functional areas, but recent evidence suggests that the striatum comprises multiple overlapping and smoothly varying gradients (i.e.

Isolating the impact of antipsychotic medication on metabolic health: Secondary analysis of a randomized controlled trial of antipsychotic medication versus placebo in antipsychotic medication naïve first-episode psychosis (the STAGES study).

Background: Cardiovascular and metabolic diseases are the leading contributors to the early mortality associated with psychotic disorders. To date, it has not been possible to disentangle the effect of medication and non-medication factors on the physical health of people with a first episode of psychosis (FEP). This study aimed to isolate the effects of antipsychotic medication on anthropometric measurements, fasting glucose and lipids.

Co-occurring first-episode psychosis and borderline personality pathology in an early intervention for psychosis cohort.

Introduction: Borderline personality disorder (BPD) is common among people diagnosed with first episode of psychosis (FEP), but is often under-recognized and under-researched. This study aimed to determine: (i) the prevalence of borderline personality pathology (subthreshold features and categorical disorder) in a FEP cohort (termed FEP + BPP); (ii) demographic and clinical factors associated with FEP + BPP; (iii) the symptomatic and functional outcomes.

Methods: This study was conducted within the Early Psychosis Prevention and Intervention Centre (EPPIC) at Orygen over the 30-month period between 2014 and 2016.

Decisional capacity in young people with first episode psychosis, major depressive disorder and no mental disorder.

We aimed to (1) examine decisional capacity for treatment in young people (aged 15 to 25 years) with first-episode psychosis (FEP), Major Depressive Disorder (MDD) and no mental disorder, and (2) determine which theoretically relevant factors are associated with, and predict decisional capacity. We assessed decisional capacity (using MacArthur Competence Assessment Tool-Treatment; MacCAT-T), cognitive abilities, insight and symptom severity in young people with no mental disorder ( = 38), MDD ( = 38) and FEP ( = 18) from inpatient and outpatient services. Most young people with MDD (84.

Frontostriatothalamic effective connectivity and dopaminergic function in the psychosis continuum.

Dysfunction of fronto-striato-thalamic (FST) circuits is thought to contribute to dopaminergic dysfunction and symptom onset in psychosis, but it remains unclear whether this dysfunction is driven by aberrant bottom-up subcortical signalling or impaired top-down cortical regulation. We used spectral dynamic causal modelling of resting-state functional MRI to characterize the effective connectivity of dorsal and ventral FST circuits in a sample of 46 antipsychotic-naïve first-episode psychosis patients and 23 controls and an independent sample of 36 patients with established schizophrenia and 100 controls. We also investigated the association between FST effective connectivity and striatal 18F-DOPA uptake in an independent healthy cohort of 33 individuals who underwent concurrent functional MRI and PET.

Functional Connectivity in Antipsychotic-Treated and Antipsychotic-Naive Patients With First-Episode Psychosis and Low Risk of Self-harm or Aggression: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Altered functional connectivity (FC) is a common finding in resting-state functional magnetic resonance imaging (rs-fMRI) studies of people with psychosis, yet how FC disturbances evolve in the early stages of illness, and how antipsychotic treatment influences these disturbances, remains unknown.

Objective: To investigate longitudinal FC changes in antipsychotic-naive and antipsychotic-treated patients with first-episode psychosis (FEP).

Design, Setting, And Participants: This secondary analysis of a triple-blind, randomized clinical trial was conducted over a 5-year recruitment period between April 2008 and December 2016 with 59 antipsychotic-naive patients with FEP receiving either a second-generation antipsychotic or a placebo pill over a treatment period of 6 months.

Cognitive ability and metabolic physical health in first-episode psychosis.

Cognitive impairments are a core feature of first-episode psychosis (FEP), arising before illness onset and antipsychotic exposure. Individuals with chronic psychosis experience poorer physical health while taking antipsychotic medication, but health disparities may be evident at FEP onset, prior to antipsychotic exposure. Given the links between cognition and physical health in healthy populations, the aim was to explore whether cognition and physical health are associated in FEP, which could inform early physical health interventions for cognition in FEP.

Differentiating the effect of antipsychotic medication and illness on brain volume reductions in first-episode psychosis: A Longitudinal, Randomised, Triple-blind, Placebo-controlled MRI Study.

Changes in brain volume are a common finding in Magnetic Resonance Imaging (MRI) studies of people with psychosis and numerous longitudinal studies suggest that volume deficits progress with illness duration. However, a major unresolved question concerns whether these changes are driven by the underlying illness or represent iatrogenic effects of antipsychotic medication. In this study, 62 antipsychotic-naïve patients with first-episode psychosis (FEP) received either a second-generation antipsychotic (risperidone or paliperidone) or a placebo pill over a treatment period of 6 months.

"When I'm Thinking Straight, I Can Put Things in Place for When I'm Not." | Exploring the Use of Advance Statements in First-Episode Psychosis Treatment: Young People, Clinician, and Carer Perspectives.

Advance statements represent a promising but relatively unexplored means to empower young people with first-episode psychosis to actively participate in their own mental health care. This qualitative study explored the use of advance statement's for young people with first-episode psychosis, as well as their carers and clinicians, and provided actionable feedback on how to better meet the needs and preferences of these key stakeholders and more effectively implement advance statements in clinical settings.

The potential impact of COVID-19 on psychosis: A rapid review of contemporary epidemic and pandemic research.

The COVID-19 outbreak may profoundly impact population mental health because of exposure to substantial psychosocial stress. An increase in incident cases of psychosis may be predicted. Clinical advice on the management of psychosis during the outbreak needs to be based on the best available evidence.

Testing the Interpersonal-Cognitive Model of Auditory Verbal Hallucinations in Youths with Either Early-Stage Borderline Personality Disorder or First-Episode Schizophrenia Spectrum Disorder.

This is the first study to explore interpersonal schemata in outpatient youths (age 15-25 years) with early-stage borderline personality disorder (BPD) and auditory verbal hallucinations (AVH). It also aimed to replicate, in a transdiagnostic youth sample, the finding from studies of adults with AVH that negative beliefs about the self and others lead to negative appraisals of voices, which in turn elicits depression. The following 3 groups were compared: youth with BPD+AVH (n = 23), youth with schizophrenia spectrum disorder (SZ) with AVH (SZ+AVH, n = 20), and youths with BPD who did not experience AVH (BPD no AVH, n = 23).

Preliminary Evidence for the Cognitive Model of Auditory Verbal Hallucinations in Youth With Borderline Personality Disorder.

This is the first study to explore cognitive, emotional, and behavioral responses to voices in youth with borderline personality disorder (BPD) compared with those with schizophrenia spectrum disorder (SZ), and to examine if negative appraisals of voices predict depression and anxiety across the groups. The sample comprised 43 outpatients, aged 15-25 years, who reported auditory verbal hallucinations (AVH) and were diagnosed with either (DSM-5) BPD or SZ. Data were collected using the Psychotic Symptom Rating Scales, the revised Beliefs About Voices Questionnaire, the Voice Rank Scale, and the Depression Anxiety Stress Scale.

Aripiprazole compared with placebo for auditory verbal hallucinations in youth with borderline personality disorder: Protocol for the VERBATIM randomized controlled trial.

Aim: Up to half of patients with borderline personality disorder report auditory verbal hallucinations that are phenomenologically indistinguishable from those in schizophrenia, occur early in the course of the disorder, and are enduring, distressing and disabling. In clinical practice, this symptom is widely assumed to be unresponsive to treatment with antipsychotic medication and early intervention is rarely offered. The Verbal Experiences Response in Borderline personality disorder to Aripiprazole TrIal Medication (VERBATIM) study aims to be the first controlled trial to investigate the effectiveness of conventional pharmacotherapy for this symptom in this patient group.

Exploratory comparison of auditory verbal hallucinations and other psychotic symptoms among youth with borderline personality disorder or schizophrenia spectrum disorder.

Objective: This study explored phenomenological aspects of auditory verbal hallucinations (AVH) and other psychotic symptoms among youth with borderline personality disorder (BPD).

Methods: Sixty-eight outpatients, aged 15 to 25 years, were categorized into three groups according to their primary Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnosis and AVH symptom profile; BPD + AVH (n = 23), schizophrenia spectrum disorder (SZ) + AVH (n = 22) and BPD with no AVH (n = 23).

Results: No differences in AVH were found between BPD + AVH and SZ + AVH.

Staged treatment and acceptability guidelines in early psychosis study (STAGES): A randomized placebo controlled trial of intensive psychosocial treatment plus or minus antipsychotic medication for first-episode psychosis with low-risk of self-harm or aggression. Study protocol and baseline characteristics of participants.

Aim: It is now necessary to investigate whether recovery in psychosis is possible without the use of antipsychotic medication. This study will determine (1) whether a first-episode psychosis (FEP) group receiving intensive psychosocial interventions alone can achieve symptomatic remission and functional recovery; (2) whether prolonging the duration of untreated psychosis (DUP) in a sub-group according to randomisation will be associated with a poorer outcome and thereby establish whether the relationship between DUP and outcome is causative; and (3) whether neurobiological changes observed in FEP are associated with the psychotic disorder or antipsychotic medication. Baseline characteristics of participants will be presented.

Early psychosis workforce development: Core competencies for mental health professionals working in the early psychosis field.

Aim: The aim of this study was to identify the core competencies required of mental health professionals working in the early psychosis field, which could function as an evidence-based tool to support the early psychosis workforce and in turn assist early psychosis service implementation and strengthen early psychosis model fidelity.

Method: The Delphi method was used to establish expert consensus on the core competencies. In the first stage, a systematic literature search was conducted to generate competency items.

Does co-occurring borderline personality disorder influence acute phase treatment for first-episode psychosis?

Background: This aims of this study were: (1) to determine the prevalence of co-occurring borderline personality disorder (BPD) in a first-episode psychosis (FEP) sample; (2) to determine differences between patients with and without BPD on demographics, comorbidities and clinical risks and other variables; and (3) to examine whether BPD comorbidity influenced treatment received by patients for FEP during their first 3 months after service entry to a specialist early psychosis service.

Methods: A file audit was conducted for 100 consecutive admissions to an early psychosis service. Patients with a clinician-rated co-occurring diagnosis of BPD were compared with patients without clinician-rated BPD on a range of variables.
