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 an association.
