What Is REM OSA?
The term REM-related obstructive sleep apnea (OSA) is used loosely by sleep clinicians when the polysomnogram (PSG) reveals obstructive apneas and hypopneas that occur predominantly or exclusively during REM sleep.
Does OSA affect memory?
Obstructive sleep apnea (OSA) is estimated to affect over 936 million people worldwide, and people with OSA are known to suffer memory problems and depression.
What Is REM predominance?
Rapid eye movement (REM) predominant OSA is a prevalent disorder that is independently associated with adverse cardiometabolic outcomes and impairment of human spatial navigational memory.
Does sleep apnea interrupt REM?
Although sleep apnea can occur during any stage of sleep, it is often worst during REM sleep because of reduced muscle tone in the upper airway that naturally occurs during REM sleep. Some individuals, in fact, have apnea that only occurs during REM sleep.
Is REM sleep good?
All sleep is important, but REM sleep in particular plays an important role in dreaming, memory, emotional processing, and healthy brain development.
Can CPAP reverse dementia?
Yes! But you need to stick with the program. In the 2017 study from the American Academy of Sleep Medicine,² only limited improvements were seen after three months of treatment with CPAP. However, after just one year, CPAP therapy led to an almost complete reversal of white matter (brain) abnormalities.
Why is my REM sleep so high?
Getting an unusually large amount of REM sleep in a given night is often an indication that you are sleep deprived. Your body routinely gets most of its REM sleep later in the night, during the final hours that you are asleep.
Does sleep apnea cause crazy dreams?

What is pink noise for sleep?

Does sleep apnea shorten life span?
Risks of obstructive sleep apnea Sleep apnea is dangerous because if untreated, it leads to high blood pressure and is associated with an increased chance of heart attack, abnormal heart rhythms and heart failure. Studies have shown that sleep apnea can decrease life expectancy by several years.
Can CPAP cause brain damage?
This brain damage was accompanied by impairments to cognition, mood and daytime alertness. Although three months of CPAP therapy produced only limited improvements to damaged brain structures, 12 months of CPAP therapy led to an almost complete reversal of white matter abnormalities.
How much REM is too much?
For healthy adults, 20-25% of your total time asleep should be REM sleep. That’s where the 90-minute number mentioned above comes from. If you sleep for 7-8 hours, 20% of that equates to roughly an hour-and-a-half, or 90 minutes. However, it’s worth noting that the amount of REM sleep we need also declines with age.
