Intellectual, neurocognitive, and academic achievement in abstinent adolescents with cannabis use disorder.

ABSTRACT: The active component of cannabis, delta-9 tetrahydrocannabinol (THC), has a long half-life and widespread neurocognitive effects. There are inconsistent reports of neurocognitive deficits in adults and adolescents with cannabis use disorders (CUD), particularly after a period of abstinence.This study aims to examine neurocognitive measures (IQ, academic achievement, attention, memory, executive functions) in abstinent adolescents with CUD, while controlling for demographic, psychopathology, and poly-substance confounders.We investigated neurocognitive performance in three groups: adolescents with CUD after successful first treatment and in full remission (n?=?33); controls with psychiatric disorders without substance use disorder history (n?=?37); and healthy adolescents (n?=?43).Adolescents with psychiatric disorders, regardless of CUD status, performed significantly worse than the healthy adolescents in academic achievement. No group differences were seen in IQ, attention, memory, or executive functions. Lower academic achievement was positively associated with younger age of CUD onset, regular cannabis use, and maximum daily use. In the CUD group, lifetime nicotine use episodes were negatively associated with IQ. Lower overall neurocognitive function was associated with younger age of onset of regular cannabis use and relapse within the 1 year follow-up.Verifiably, abstinent adolescents with CUD history did not differ from the two comparison groups, suggesting that previously reported neurocognitive deficits may be related to other factors, including residual drug effects, preexisting cognitive deficits, concurrent use of other substances (e.g., nicotine), or psychopathology. Adolescents with CUD may not be vulnerable to THC neuropsychological deficits once they achieve remission from all drugs for at least 30 days.

Project description:BackgroundOver a fifth of children and adolescents suffer with asthma or atopic disease. It is unclear whether asthma impacts academic performance in children and adolescents, and little is known about the association of eczema, food allergy or hayfever and academic performance.ObjectiveTo examine whether asthma, eczema, food allergy or hayfever impacts on adolescent academic performance and to assess the role of unmeasured confounding.MethodsThis study used the Childhood and Adolescent Twin Study of Sweden cohort born 1992-1998. At age 9-12 years, parents reported on their child's ever or current asthma, eczema, food allergy and hayfever status (n = 10 963). At age 15, linked national patient and medication register information was used to create current and ever asthma definitions including severe and uncontrolled asthma for the same children. Academic outcomes in Grade 9 (age 15-16 years) included: eligibility for high school (Grades 10-12), and total mark of the best 16 subject units, retrieved from the Grade 9 academic register. Whole cohort analyses adjusted for known covariates were performed, and co-twin control analyses to assess unmeasured confounders.ResultsThere were no associations found for asthma or food allergy at 9-12 years and academic outcomes in adolescence. In addition, at age 15, there were no statistically significant associations with current, ever, severe or uncontrolled asthma and academic outcomes. Eczema and hayfever at age 9-12 years were found to be positively associated with academic outcomes; however, co-twin control analyses did not support these findings, suggesting the main analyses may be subject to unmeasured confounding.Conclusion and clinical relevanceHaving asthma or an atopic disease during childhood or adolescence does not negatively impact on academic performance. This information can be used by clinicians when talking with children and parents about the implications of living with asthma or atopic disease.

Project description:BackgroundIncreasing understanding of the pathways and processes of recovery from cannabis use disorder may help in designing effective and attractive interventions to promote recovery. We report insights from individuals who had successfully recovered from cannabis use disorder with a variety of pathways. Recovered individuals describe their perceptions of why they developed the problem, why they were successful in recovering, and the advice they would offer to individuals with similar problems.MethodsMedia announcements were used to recruit 119 volunteers who met lifetime but not past year criteria for cannabis use disorder. Participants were asked open-ended questions which were content analyzed and compared between individuals who whose recoveries were treatment-assisted (45%) versus natural (55%) and between individuals who were abstinent (57%) versus those who continued non-problematic consumption (43%).ResultsParticipants most frequently described their problems as having developed due to the use of cannabis to cope, because of environmental and social influences, and enjoyment of the positive effects. Success in recovery was attributed to focusing on reasons for change, goal commitment to change, and conquering denial/self-deception. Treatment-assisted participants were more likely to perceive that they overcame their cannabis problem due to treatment/self-help and conquering underlying issues, whereas naturally recovered participants were more likely to describe focusing on reasons for change, will power, and lost enjoyment/lifestyle change. Treatment-assisted participants were more likely to recommend seeking help/social support and naturally recovered participants were more likely to endorse reflecting on reasons for change, engaging in hobbies/distracting activities, and stimulus control/avoidance/change social environment. The majority recommended professional treatment (79.1%) and self-help materials (76.9%), and a little over half (53.2%) would also recommend natural recovery.ConclusionsThese insights from people with lived experience further support previous research that treatment-assisted and natural recoveries are for the most part similar with respect to the recovery process. However, participants, whether or not they had had treatment involvement, recommended the use of treatment and self-help materials to sharpen their focus on the reasons to change and to enhance their commitment to change. At the same time, they saw value in the efforts of individuals to recovery without help.
