Effect of single caffeine intake on neuropsychological functions in healthy volunteers: A double-blind placebo-controlled study.

ABSTRACT:

Objective

We investigated the effects of a single instance of caffeine intake on neurocognitive functions and driving performance in healthy subjects using an established cognitive battery and a driving simulator system.

Methods

This study was conducted in a double-blind, randomized, placebo-controlled manner from February 19, 2016 to August 6, 2016. Caffeine intake was discontinued 3 days prior to the study.
