Sleep Disorders Don’t Just Exhaust You. New Research Shows They Change Your Brain

Three key brain regions interact during sleep to support memory formation

Researchers at Kennedy Krieger Institute and Johns Hopkins Medicine have discovered that memory consolidation during sleep depends on coordinated activity among three brain regions and disruptions to this activity can impair memory performance.

Struggling to Sleep? Researchers Just Made a Surprising Discovery

Scientists uncovered a hidden brain signal that could reshape future sleep treatments—but questions remain.

Sleep apnea during REM sleep linked to memory-related brain changes

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain's small blood vessels, according to a new study. The study found the brain changes were strongly associated with the severity of drops in oxygen levels during rapid eye movement (REM) sleep. The study does not prove that sleep apnea causes this degeneration; it only shows…
