The Impact of Caffeine on Working Memory and Brain Activity
A study published in Scientific Reports suggests that daily caffeine intake may hinder working memory function instead of enhancing it. Previous research focused on acute caffeine intake, but this study investigated the effects of sustained caffeine use on cognitive performance. The study found that daily moderate-dose caffeine intake compromised working memory, as participants displayed higher error rates and longer reaction times during memory-related tasks. Brain imaging revealed increased activity in attention and motor control regions during working memory tasks, but no significant differences in brain activity among the three conditions. The study highlights the need for further research to understand the molecular mechanisms underlying caffeine's effects on cognitive functions.
