Abstract

Objective

To review the effects of methylphenidate on cognitive enhancement, memory, and performance in medical students.

Methods

Areview of four databases (LILACS, PubMed, ScienceDirect, and SciELO), analyzing the title and abstract of all articles published between 1990 and 2012 in English, Portuguese, and Spanish. Selected articles were read in entirety, including in the review those that met the established criteria.

Results

The prevalence of use among medical students reached 16%, with no gender dif- ference. Most students began using the drug after entering the university, and the reasons cited to justify it are related to enhancing academic performance.

Conclusion

There is no evidence in the literature that the use of methylphenidate is benefi- cial in terms of memory or learning. The drug simply increases wakefulness and alertness, reducing the time of sleep.

医学生使用哌甲酯的系统回顾

目的探讨哌醋甲酯对医学生认知增强、记忆和运动能力的影响。方法:检索LILACS、PubMed、ScienceDirect和SciELO 4个数据库，分析1990 - 2012年间发表的所有英文、葡萄牙文和西班牙文文章的标题和摘要。选定的文章被完整地阅读，包括在审查中符合既定标准的文章。结果医学生用药率达16%，无性别差异。大多数学生在进入大学后就开始使用毒品，理由是为了提高学习成绩。结论文献中没有证据表明使用哌甲酯对记忆和学习有好处。这种药只是增加清醒和警觉性，减少睡眠时间。
