Scientists have discovered that sleep disorders are associated with structural changes in brain regions that control attention, decision-making, and emotions, potentially explaining why disrupted sleep can affect everyday thinking and behavior. The findings, drawn from 57 brain imaging studies, reveal both shared and disorder-specific patterns that could lead to more targeted treatments.

Scientists have discovered a surprising two-way relationship between sleep and growth hormone, revealing how the brain carefully balances physical recovery with wakefulness. The findings could help explain why poor sleep harms metabolism and brain health, potentially opening the door to new treatments for sleep and neurological disorders.
