New study on disrupted sleep and adolescent cognitive development suggests links to psychosis risk

Disrupted sleep during adolescence is associated with a number of mental health symptoms. Cross-lagged panel modelling on the relationship between adolescent sleep patterns and psychotic symptoms indicates a longitudinal relationship that is explained by the effects of disrupted sleep on neuropsychological functions such as inhibitory control.

Screen time, impulsivity, neuropsychological functions and their relationship to growth in ADHD symptoms

New study in Scientific Reports shows the relationship between screen time and ADHD symptoms is explained by the effects of screen time on neuropsychological and behavioural measures of impulsivity and executive functions. This relationship was found to last over time only in the case of social media use, suggesting an enduring influence on teen’s behavior and mental health and highlighting a need to identify measures to help young people better manage their susceptibility to social media.

Annual meeting of the Canadian Cannabis and Psychosis Research Team

Over 40 researchers from 10 different Canadian research laboratories met in Montreal to share research findings on cannabis and adolescent brain development. A number of common themes across animal and human research were identified, and new research directions were discussed. Sex, gender and pubertal factors appear key to understanding the link between adolescent cannabis use and psychosis risk

New study shows validity of the four-factor personality model of substance use vulnerability in opioid dependent adults

This elegant qualitative analysis of situational, cognitive-emotional and behavioural triggers for substance misuse in opioid dependent adults receiving opioid substitution therapy showed that substance use behaviours were linked to personality-specific thinking and behavioural reactions to major life stressors. This research provides further support for the application of personality-targeted psychological interventions as adjuncts to opioid substitution therapy.

Kick-off Meeting for New Collaboration Between Three Canadian Pediatric Hospitals: CHUSJ, Sickkids, and Alberta Children's

A new collaboration has been launched between researchers across three paediatric hospitals in Canada. Through a hybrid in-person and virtual meeting, more than twenty experts from clinical neuropsychology, neuroimaging and bioinformatics met over two days to design new tools to accelerate research on neurodevelopment and child brain health. 


Screentime Primes Adolescent Aggressive Behaviours and Conduct Problems

Longitudinal modelling of the relationships between adolescents frequency and type of screentime and aggressive behaviours suggests that social media, video gaming and computer use were associated with short-term increases in aggressive behaviours. Social media also showed a longer-term relationship with antisocial behaviours. Television watching was associated with promotion of prosocial behaviours. Digital media that is subject to editorial review might be less harmful for adolescents.


Relationship between bullying experiences and mental health explained by changes in connectivity in brain regions involved in emotion processing

A new study published Frontiers Psychiatry - A longitudinal mediation study of peer victimization and resting-state functional connectivity as predictors of psychopathology. Results showed that rsFC of the amygdala-posterior insula significantly mediated the lagged within-person association of peer victimisation and internalizing symptoms. Bullying experiences may lead to long-lasting changes in neural communication between regions implicated in emotion regulation and sensory/pain perception

Prioritizing youth voices amidst the opioid overdose and health crises

There may be a widespread perception that opioid use only impacts older adults. However, evidence now shows that the opioid overdose and health crises has, and continues to have, deleterious effects on youth and young adults ages 15-24. There is some evidence in Canada that shows the pandemic and the associated restrictions exacerbated morbidity and mortality due to opioids among young people. Contemporary journalistic exposes have also revealed the heartbreaking consequences...

A functional neuroimaging study of self-other processing alterations in atypical developmental trajectories of psychotic-like experiences

Self-disturbances constitute a hallmark of psychosis, but it remains unclear whether these alterations are present in at-risk populations. The present study addressed this question by measuring neural correlates of self-other processing in youth belonging to three developmental trajectories of psychotic experiences. We found alterations in one of the atypical trajectories that are similar to what is reported in individuals with schizophrenia.

Students who attended schools where the program was implemented were compared to students who attended schools where the program was not implemented and results showed a significant reduction in the likelihood of reporting suicidal ideation over a three-year period. 


Are Brain Responses to Emotion a Reliable Endophenotype of Schizophrenia? An Image-based fMRI Meta-analysis - ScienceDirect

Impaired emotion processing constitutes a key dimension of schizophrenia and a possible endophenotype of this illness. Empirical studies consistently report poorer emotion recognition performance in patients with schizophrenia as well as in individuals at enhanced risk of schizophrenia (“at risk”). fMRI studies also report consistent patterns of abnormal brain activation in response to emotional stimuli in patients, in particular decreased amygdala activation. In contrast, brain-level...


Neural alterations of emotion processing in atypical trajectories of psychotic-like experiences

Studying developmental trajectories of psychotic-like experiences can help us understand the brain changes that occur during the development of psychosis. In this study, we have shown that atypical trajectories of psychotic-like experiences are associated with changes in brain regions that are involved in emotion salience and face perception, similarly to what is reported in schizophrenia.
