Adolescent neurocognitive development and impacts of substance use: Overview of the adolescent brain cognitive development (ABCD) baseline neurocognition battery

Developmental Cognitive Neuroscience, Journal Year: 2018, Volume and Issue: 32, P. 67 - 79

Published: Feb. 21, 2018

Adolescence is characterized by numerous social, hormonal and physical changes, as well a marked increase in risk-taking behaviors. Dual systems models attribute adolescent to tensions between developing capacities for cognitive control motivational strivings, which may peak at this time. A comprehensive understanding of neurocognitive development during the period necessary permit distinction premorbid vulnerabilities consequences behaviors such substance use. Thus, prospective assessment fundamental aims newly launched Adolescent Brain Cognitive Development (ABCD) Consortium. This paper details rationale ABC'lected measures neurocognition, presents preliminary descriptive data on an initial sample 2299 participants, provides context how large-scale project can inform our neurodevelopment.

Beyond stereotypes of adolescent risk taking: Placing the adolescent brain in developmental context

Developmental Cognitive Neuroscience, Journal Year: 2017, Volume and Issue: 27, P. 19 - 34

Published: July 26, 2017

Recent neuroscience models of adolescent brain development attribute the morbidity and mortality this period to structural functional imbalances between more fully developed limbic regions that subserve reward emotion as opposed those enable cognitive control. We challenge interpretation by distinguishing risk-taking peaks during adolescence (sensation seeking impulsive action) from risk taking declines monotonically childhood adulthood (impulsive choice other decisions under known risk). Sensation is primarily motivated exploration environment ambiguous contexts, while action, which likely be maladaptive, characteristic a subset youth with weak control over motivation. Risk occurs conditions risks reflects increases in executive function well aversion based on gist-based reasoning. propose an alternative Life-span Wisdom Model highlights importance experience gained through adolescence. propose, therefore, recognize adaptive roles cognition play provide complete helpful picture development.

Adolescent neurobiological susceptibility to social context

Developmental Cognitive Neuroscience, Journal Year: 2015, Volume and Issue: 19, P. 1 - 18

Published: Dec. 24, 2015

Adolescence has been characterized as a period of heightened sensitivity to social contexts. However, adolescents vary in how their contexts affect them. According neurobiological susceptibility models, endogenous, biological factors confer some individuals, relative others, with greater environmental influences, whereby more susceptible individuals fare the best or worst all depending on environment encountered (e.g., high vs. low parental warmth). Until recently, research guided by these theoretical frameworks not incorporated direct measures brain structure function index this sensitivity. Drawing prevailing models adolescent neurodevelopment and growing number neuroimaging studies interrelations among contexts, brain, developmental outcomes, we review that supports idea context for understanding why differ development well-being. We propose is shaped brain-based individual differences - be they positive negative such those created through relationships parents/caregivers peers. Ultimately, recommend future measure operationalize moderate influence outcomes.

Annual Research Review: Neural contributions to risk‐taking in adolescence – developmental changes and individual differences

Journal of Child Psychology and Psychiatry, Journal Year: 2016, Volume and Issue: 57(3), P. 353 - 368

Published: Jan. 6, 2016

Risk-taking, which involves voluntary choices for behaviors where outcomes remain uncertain, undergoes considerable developmental changes during childhood, adolescence, and early adulthood. In addition, risk-taking is thought to be a key element of many externalizing disorders, such as ADHD, delinquency, conduct disorder, substance abuse. this review, we will discuss the potential adaptive nonadaptive properties in childhood adolescence.We propose that brain architecture function are crucial underlying these trajectories. We first identify how subcortical cortical interactions important understanding behavior adults. Next, show network underlie behavior. Finally, explore differences can behavioral disorders conclude longitudinal studies importance trajectories, currently underway.

Annual Research Review: On the developmental neuropsychology of substance use disorders

Journal of Child Psychology and Psychiatry, Journal Year: 2016, Volume and Issue: 57(3), P. 371 - 394

Published: Feb. 18, 2016

Background Adolescence represents a period of development during which critical biological, as well social and cognitive, changes occur that are necessary for the transition into adulthood. A number researchers have suggested pattern normative brain occurs this not only predisposes adolescents to engage in risk behaviours, such experimentation with drugs, but they additionally make adolescent more vulnerable direct pharmacological impact substances abuse. The neural circuits we examine review involve cortico‐basal‐ganglia/limbic networks implicated processing rewards, emotion regulation, control behaviour, cognition. Findings Conclusions We identify certain neurocognitive personality/comorbidity‐based factors onset substance misuse adolescence, summarise evidence suggesting these may be further impacted by effect drugs on underlying vulnerability.

Individual differences in risk-taking tendencies modulate the neural processing of risky and ambiguous decision-making in adolescence

NeuroImage, Journal Year: 2018, Volume and Issue: 172, P. 663 - 673

Published: Feb. 2, 2018

Although many neuroimaging studies have investigated adolescent risk taking, few dissociated between decision-making under (known probabilities) and ambiguity (unknown probabilities). Furthermore, which brain regions are sensitive to individual differences in task-related self-reported taking remains elusive. We presented 198 adolescents (11-24 years, an age-range prominent) with fMRI paradigm that separated (choosing gamble or not) reward outcome processing (gains, no gains) risky ambiguous conditions, related this taking. observed distinct neural mechanisms underlying gambling, more prominently associated activation parietal cortex, dorsolateral prefrontal cortex (PFC), as well medial PFC during processing. Individual were positively ventral striatum the decision phase, specifically for risk, negatively insula dorsomedial activation, ambiguity. Moreover, phase seemed a prominent marker daily-life greater was reduced PFC. Together, study demonstrates importance of considering multiple risk-taking measures, contextual moderators, understanding
