Background:
Methylphenidate is a central nervous system stimulant commonly used in the treatment of attention deficit hyperactivity disorder (ADHD). While it is known to improve sustained attention, its effects on individuals without clinical conditions remain controversial. This integrative review investigates the impact of MPH in nontherapeutic settings, with a focus on cognitive and behavioral outcomes and potential side effects.
Methods:
A systematic search was conducted across multiple electronic databases, including PubMed, EMBASE, Scopus, Web of Science, and PsycINFO, covering studies published from 2010 to 2021, according to a previously published protocol.
Results:
A total of 33 studies were included. While findings indicate that a single dose of methylphenidate may improve attention and readiness in cognitive tasks and may enhance the efficiency of visual and motor processing, the literature about its effects on working memory, inhibitory response, food consumption, and subjective mood alteration remains controversial. Also, methylphenidate shows some increase in heart rate and blood pressure.
Conclusion:
This review highlights robust evidence regarding the effects of methylphenidate on attention and readiness, in addition to minimal overall cardiovascular impact. Also, it reveals a significant lack of research on the chronic effects of the medication and lack of standardization in the methods used to measure the stimulant's effects. Limitations include the lack of a meta-analysis and a potentially restrictive search strategy, which may have reduced the number of studies analyzed.
