One of the most robust neurochemical abnormalities reported in patients with schizophrenia is an increase in dopamine (DA) synthesis and release, restricted to the dorsal striatum (DS). This hyper functionality is strongly associated with psychotic symptoms and progresses in those who later transition to schizophrenia. To understand the implications of this progressive neurobiology on brain function, we have developed a model in rats which we refer to as EDiPs (Enhanced Dopamine in Prodromal schizophrenia).

Introduction: People with psychotic disorders commonly feature broad decision-making impairments that impact their functional outcomes. Specific associative/reinforcement learning problems have been demonstrated in persistent psychosis. But these phenotypes may differ in early psychosis, suggesting that aspects of cognition decline over time.

Comorbidity between major depressive disorder and physical diseases: a comprehensive review of epidemiology, mechanisms and management.

World Psychiatry

October 2023

Institute for Mental and Physical Health and Clinical Translation (IMPACT), School of Medicine, Deakin University, Geelong, VIC, Australia.

Article Synopsis
  • People with physical diseases like cardiovascular issues, cancer, and neurodegenerative disorders are at a higher risk for major depressive disorder (MDD), and those with MDD also face increased risks for various physical diseases, creating a cycle of health challenges.
  • This comorbidity leads to worse health outcomes, higher treatment costs, and more complex clinical management due to overlapping symptoms and treatments, highlighting the need for integrated care approaches.
  • The text explores shared genetic and biological factors, social influences, and effective treatment strategies for managing both MDD and common physical diseases, emphasizing the importance of lifestyle interventions and collaborative care models.

Article Synopsis
  • Many patients discontinue antidepressant medication (ADM) without a doctor's recommendation, with 15.7% ceasing use independently compared to 10.9% who followed their prescriber's advice.
  • The primary reason for stopping was feeling better (46.6%), particularly noted by those who discontinued within the first two weeks of treatment, while concerns like perceived ineffectiveness and costs were less common.
  • Factors influencing discontinuation include country income levels, employment status, and the prescribing professional, indicating that patient-reported reasons are complex and vary widely among individuals.

ADuLT: An efficient and robust time-to-event GWAS.

Nat Commun

September 2023

National Centre for Register-Based Research, Aarhus University, Aarhus, Denmark.

Proportional hazards models have been proposed to analyse time-to-event phenotypes in genome-wide association studies (GWAS). However, little is known about the ability of proportional hazards models to identify genetic associations under different generative models and when ascertainment is present. Here we propose the age-dependent liability threshold (ADuLT) model as an alternative to a Cox regression based GWAS, here represented by SPACox.

Beyond the Global Brain Differences: Intraindividual Variability Differences in 1q21.1 Distal and 15q11.2 BP1-BP2 Deletion Carriers.

Biol Psychiatry

January 2024

Department of Medical Genetics, Oslo University Hospital, Oslo, Norway; Norwegian Centre for Mental Disorders Research (NORMENT), Division of Mental Health and Addiction, Oslo University Hospital and Institute of Clinical Medicine, University of Oslo, Oslo, Norway; KG Jebsen Centre for Neurodevelopmental Disorders, University of Oslo, Oslo, Norway.

Article Synopsis
  • Carriers of specific genetic variants (1q21.1 distal and 15q11.2 BP1-BP2) show both regional and global brain structure differences compared to noncarriers, but analyzing these differences can be complicated.
  • The study used MRI data from various groups (carriers and noncarriers) to assess how regional brain characteristics diverge from overall brain structure differences.
  • Findings revealed that certain brain regions in carriers exhibited distinct patterns of cortical surface area and thickness that deviated from the global average, suggesting more complex effects of these genetic variants on brain development.

Cocaine is one of the most widely used and increasingly popular illicit psychoactive drugs. Unlike other commonly used substances of abuse, cocaine has no pharmacological therapies to treat addiction or aid in rehabilitation. Immunopharmacology has long been touted as a possible avenue to develop effective anticocaine therapies; however, lack of efficacy and designs which are not consistent with simple large-scale production have hindered vaccine translation.

Background: People with schizophrenia have a higher risk of mortality compared to the general population, which has not improved over time. The majority of premature deaths are due to comorbid physical diseases, driven by interrelated factors operating at the individual level, through health systems and influenced by social determinants of health. A holistic understanding of this problem and the causal pathways linking these factors together is lacking.

Antagonism of D2 receptors via raclopride ameliorates amphetamine-induced associative learning deficits in male mice.

Behav Brain Res

October 2023

Queensland Brain Institute, The University of Queensland, St Lucia, QLD 4072, Australia; Queensland Centre for Mental Health Research, Wacol, QLD 4076, Australia. Electronic address:

Dopamine levels in the dorsomedial striatum (DMS) are highly dynamic and are thought to underly the encoding of action-outcome associations. Although it is known that amphetamine disrupts the learning that is required for goal-directed action, the role of D1 and D2 receptors in this process has not been established. In this study, we examined the role of D1 and D2 receptor antagonists on learning in response to amphetamine.

We recently introduced the Cre/Lox technology in our laboratory for both transient (mRNA injections) and stable/transgenic experiments. We experienced significant issues such as silencing, mosaicism, and partial recombination using both approaches. Reviewing the literature gave us the impression that these issues are common among the zebrafish community using the Cre/Lox system.

Aims: Given the increasing number of Hematopoietic Stem Cell Transplantations (HSCT) performed world-wide, the increasing likelihood of survival following HSCT, and the profound physical, psychosocial, and emotional impact of HSCT on survivors, their carers and families, it is important to identify factors that may contribute to or support post-traumatic growth (PTG) after transplant. In this study, we aimed to investigate the prevalence of PTG in an Australian cohort of long-term allogeneic HSCT survivors and describe associations between PTG and relevant clinical, sociodemographic and psychological variables.

Methods: This was a large, multi-centre, cross sectional survey of Australian HSCT-survivors inviting all those transplanted in New South Wales between 2000 and 2012.

A systematic review of economic evaluations for opioid misuse, cannabis and illicit drug use prevention.

BJPsych Open

August 2023

Monash University Health Economics Group, School of Public Health and Preventive Medicine, Monash University, Australia; and Deakin Health Economics, Institute for Health Transformation, School of Health and Social Development, Deakin University, Australia.

Article Synopsis
  • Substance use disorders significantly impact global health, making the cost-effectiveness of preventive interventions crucial to assess.
  • A review of 11 economic evaluation studies indicates that while most efforts focus on preventing opioid misuse, cannabis, and illicit drug use are also considered, with promising results primarily from school-based and family-based interventions.
  • Overall, there's a need for more comprehensive economic evaluations, but current studies suggest specific programs may offer good value for money in preventing substance misuse.

Multi-PGS enhances polygenic prediction by combining 937 polygenic scores.

Nat Commun

August 2023

The Lundbeck Foundation Initiative for Integrative Psychiatric Research, iPSYCH, 8210, Aarhus V, Denmark.

Article Synopsis
  • The accuracy of polygenic scores (PGS) improves significantly with larger sample sizes, which can be difficult to obtain, but using genetically related traits can help expand these samples.
  • The study introduces a new method for creating multi-PGS from existing genome-wide association studies (GWAS) without needing to pick the most relevant studies individually.
  • The multi-PGS framework shows enhanced prediction accuracy, achieving up to a 9-fold increase for certain psychiatric disorders, and can also be applied to new biobanks and traits lacking prior GWAS data.

Article Synopsis
  • Depression is a prevalent psychiatric disorder and major global disability, and a study involving over 1.3 million people identified 243 genetic risk loci, with 64 being newly discovered, many linked to glutamate and GABA receptor genes targeted by antidepressant medications.
  • The research showed depression is highly polygenic, meaning it's influenced by many genetic variants, with about 11,700 variants accounting for 90% of heritability; many of these variants also affect other psychiatric disorders and educational outcomes.
  • The study highlighted genetic and clinical differences within depression subgroups, indicating those with a higher polygenic burden face significantly increased risks for recurrence and other mental health issues, with notable differences based on sex.
