To review the effects of methylphenidate on cognitive enhancement, memory, and performance in medical students.
A review 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.
The prevalence of use among medical students reached 16%, with no gender difference. Most students began using the drug after entering the university, and the reasons cited to justify it are related to enhancing academic performance.
There is no evidence in the literature that the use of methylphenidate is beneficial in terms of memory or learning. The drug simply increases wakefulness and alertness, reducing the time of sleep.
回顾哌醋甲酯对医学生认知增强、记忆及学习表现的影响。
检索四个数据库（拉丁美洲和加勒比地区卫生科学数据库、医学期刊数据库、科学Direct数据库和科学电子在线数据库），分析1990年至2012年间以英文、葡萄牙文和西班牙文发表的所有文章的标题和摘要。对入选文章进行全文阅读，符合既定标准的文章纳入本综述。
医学生中该药物的使用率达16%，无性别差异。大多数学生在进入大学后开始使用该药物，使用理由多与提高学业成绩有关。
文献中没有证据表明使用哌醋甲酯对记忆或学习有益。该药物仅能提高清醒度和警觉性，减少睡眠时间。
