精神活性药物的实验通常在青春期前后开始,但对青春期前后与成年人开始接触的结果差异的了解是不完整的。我们认为现有的动物研究在这方面的(甲基)安非他明。确定了一些表型,是较低的敏感性,青少年比成年人的急性影响(甲基)安非他明,包括神经毒性影响的暴饮暴食水平的接触。更多的变量是青少年期暴露对动机和认知特征的长期影响的数据。此外,调查往往排除了成人发起的接触组的关键回答问题的结果独特的青春期开始。尽管如此,从动物研究中可以清楚地看出,在青春期前后接触(甲基)安非他明,无论是自我还是他人给药,都会影响大脑的激励回路和认知功能,并改变成年人对其他药物和自然奖励的敏感性。发生在人类身上的这种后果有可能使人倾向于不幸的和潜在的灾难性的家庭、社会和生计结果。
Experimentation with psychoactive drugs is often initiated in the peri-adolescent period, but knowledge of differences in the outcomes of peri-adolescent- vs adult-initiated exposure is incomplete. We consider the existing animal research in this area for (meth)amphetamines. Established for a number of phenotypes, is lower sensitivity of peri-adolescents than adults to acute effects of (meth)amphetamines, including neurotoxic effects of binge-level exposure. More variable are data for long-term consequences of peri-adolescent exposure on motivational and cognitive traits. Moreover, investigations often exclude an adult-initiated exposure group critical for answering questions about outcomes unique to peri-adolescent initiation. Despite this, it is clear from the animal research that (meth)amphetamine exposure during the peri-adolescent period, whether self- or other-administered, impacts brain motivational circuitry and cognitive function, and alters adult sensitivity to other drugs and natural rewards. Such consequences occurring in humans have the potential to predispose toward unfortunate and potentially disastrous family, social and livelihood outcomes.
