The adolescent brain is in an active state of change as neural circuitry is refined in anticipation of adulthood. A developing brain may be more vulnerable such that environmental experiences, if sufficiently intense, can alter maturational trajectories. One such experience is substance use. As indicated by a number of recent meta-analyses, executive control processes, which include working memory, cognitive flexibility and numerous aspects of attentional, behavioral and emotional control, are impaired in the context of active substance use disorder. Neural circuitry is also impacted. Many of these recent studies focus on outcomes associated with clinically-significant levels of alcohol and/or cannabis use. But whether these impairments consistently emerge as a consequence of sub-clinical levels of use, or use that begins at early ages, is debated. This talk will review recent findings, including those recently gleaned from large-scale longitudinal studies such as the Adolescent Brain Cognitive Development (ABCD) study, to address these questions. Findings will be discussed in relation to adolescence as a sensitive period of neurodevelopment.
Intermediate: Assumes post-doctoral education status and general familiarity with topic.
1. Describe mechanisms of neurodevelopment in typically developing adolescents.
2. Apply knowledge of these mechanisms to alterations observed in the context of substance misuse, with an emphasis on the impacts of alcohol and cannabis.
3. Compare what is known about substance-related impacts in adolescents at the neural versus behavioral level.
4. Explain limitations in the literature with respect to whether adolescence can be viewed as a sensitive period for substanceuse-related pathology.
5. Explain current findings regarding adolescence as a sensitive period for substance-use-related neurotoxicity.
