The US National Institutes of Mental Health Research Domain Criteria (RDoC) seek to stimulate research into biologically validated neuropsychological dimensions across mental illness symptoms and diagnoses. RDoC framework comprises 39 functional constructs designed be revised refined, with the overall goal improving diagnostic validity treatments. This study aimed reach a consensus among experts in addiction field on 'primary' most relevant substance behavioural addictions.Forty-four were...
Background Clinical symptoms and neuropsychological deficits are longitudinally associated with functional outcome in chronic psychiatric cohorts. The current study extended these findings to young early-course outpatients, the aim of identifying cognitive markers that predict later socio-occupational functioning. Methods At baseline, 183 outpatients were assessed. Ninety-three returned for follow-up (M = 21.6 years old; SD 4.5) an average re-assessment interval months (SD 7.0), primary...
Background: The COVID-19 pandemic has resulted in high levels of psychological distress worldwide, with experts expressing concern that this could result corresponding increases addictive behaviors as individuals seek to cope their distress. Further, some may be at greater risk than others for developing problematic during times stress, such trait impulsivity and compulsivity. Despite the potential knowledge inform early detection risk, no study date examined influence compulsivity on...
To empirically derive and evaluate potential clusters of Insomnia Disorder through cluster analysis from polysomnography (PSG). We hypothesized that would differ on neurocognitive performance, sleep-onset measures quantitative (q)-EEG heart rate variability (HRV).Research volunteers with (DSM-5) completed a assessment overnight PSG total sleep time (TST), wake after onset (WASO), latency (SOL) were used to determine clusters.From 96 Disorder, derived at least two objective parameters: normal...
Neurocognitive processes are key drivers of addictive and compulsive disorders. The current study examined whether reward-related attentional capture cognitive inflexibility associated with impulsive and/or personality traits, these characteristics interact to predict greater compulsivity-related problems across obsessive-compulsive drinking behaviors.
Compulsivity is a poorly understood transdiagnostic construct thought to underlie multiple disorders, including obsessive-compulsive disorder, addictions, and binge eating. Our current understanding of the causes compulsive behavior remains primarily based on investigations into specific diagnostic categories or findings relying one two laboratory measures explain complex phenotypic variance. This proof-of-concept study drew heterogeneous sample community-based individuals (N = 45; 18-45...
Clinical staging of mental disorders proposes that individuals can be assessed at various sub-syndromal and later developed phases illness. As an adjunctive rating, it may complement traditional diagnostic silo-based approaches. In this study, we sought to determine the relationships between clinical stage neuropsychological profile in young persons presenting youth-focused health services. Neuropsychological testing 194 help-seeking people (mean age 22.6 years, 52% female) 50 healthy...
Summary Mood disorders are characterized by disabling symptoms and cognitive difficulties which may vary in intensity throughout the course of illness. Sleep–wake cycles circadian rhythms influence emotional regulation functions. However, relationships between sleep–wake disturbances experienced commonly people with mood longitudinal changes their clinical profile not well characterized. This study investigated associations initial patterns functions 50 young (aged 13–33 years) depression or...
Neurocognitive impairments robustly predict functional outcome. However, heterogeneity in neurocognition is common within diagnostic groups, and data-driven analyses reveal homogeneous neurocognitive subgroups cutting across boundaries.
Researchers are only just beginning to understand the neurocognitive drivers of addiction-like eating behaviours, a highly distressing and relatively common condition. Two constructs have been consistently linked eating: distress-driven impulsivity cognitive inflexibility. Despite large body addiction research showing that impulsivity-related traits can interact with other risk markers result in an especially heightened for addictive no study date has examined how interacts inflexibility...
Both impulsivity and compulsivity have been identified as risk factors for problematic use of the internet (PUI). Yet little is known about relationship between impulsivity, individual PUI symptoms, limiting a more precise understanding mechanisms underlying PUI.
