Caffeine's Age-Dependent Effects on Brain Complexity and Criticality During Sleep
2025-05-30
A new study reveals that caffeine affects brain complexity and criticality in an age-dependent manner. Analyzing sleep EEG data, researchers found that caffeine induced increases in complexity and criticality of brain activity in young and middle-aged adults, but not in older adults. This study provides novel insights into the effects of caffeine on the brain and age-related neurodegenerative diseases.
