Sleep apnea may steal some of your memory

Sleep apnea may make it hard for you to remember simple things, such as where you parked your car or left your house keys, according to a new study published in the Journal of Neuroscience.
In sleep apnea, people have one or more pauses in breathing or shallow breaths while you sleep.
Tests on people with severe sleep apnea showed that this ability — called spatial memory — was impaired when sleep apnea disrupted rapid eye movement (REM) sleep, even when other stages of sleep were not affected. REM sleep is the deepest level of sleep, during which dreams typically occur.
