Early motor skills may affect language development Out research showed that motor skills in 7-month-old babies predicted the rate of language development in children that went on to develop autism spectrum disorder.

A recent study from Université de Montréal reveals that caffeine affects brain activity during sleep by increasing the complexity and unpredictability of brain signals, which may interfere with the brain’s ability to recover overnight. Using EEG and artificial intelligence, researchers studied 40 adults who took caffeine or a placebo before bedtime and found that caffeine altered key brain rhythms during deep sleep. It reduced slower waves like theta and alpha—linked to restful, restorative sleep—and boosted beta waves associated with alertness and wakefulness. This shift keeps the brain in a more activated state during sleep, potentially harming memory and cognitive recovery.

Interestingly, these effects were strongest in people in their 20s. This difference likely results from younger adults having more adenosine receptors, which caffeine blocks to stimulate the brain. As adenosine builds up during the day, it causes tiredness, but caffeine interrupts this signal, keeping the brain more “awake” even during sleep. Older adults showed less impact, likely due to fewer receptors.

Researchers explained that caffeine pushes the brain into a state called “criticality,” a balance between order and chaos. While helpful for daytime focus, this state disrupts the brain’s ability to rest and repair at night. Since caffeine is widely consumed, especially to fight fatigue, understanding its effects on sleep and brain health across ages is important. The researchers call for more studies to explore how these brain changes influence daily functioning and to guide personalized caffeine use recommendations.
