Sleep Apnea Linked to Increased Dementia Risk
A new study published in the Journal of Alzheimer’s Disease, led by Dr. Melinda Jackson from the Turner Institute for Brain and Mental Health, has found a link between severe Obstructive Sleep Apnea (OSA) and an increase in the risk of dementia.
What is Sleep Apnea?
Sleep apnea is a sleeping disorder that affects an estimated 1 billion people worldwide (though many people with sleep apnea are undiagnosed). OSA occurs when the tissues in the throat collapse during sleep, cutting off oxygen to the brain. If your body stops bringing in oxygen, your brain will wake you up just enough to get your breathing again. You may not even notice your body waking up.

What is Dementia?
Dementia is a group of disorders caused by abnormal brain changes that lead to a decline in cognitive abilities. The most well-known form of dementia is known as Alzheimer’s. Dementia negatively impacts daily life and independence.
What’s the Science Behind This?
The study found that a high amount of a protein (called beta-amyloid) was found in the brains of people with severe OSA. This protein builds up in the walls of the arteries in the brain. An increase of these proteins is linked to an increased risk of dementia.
The study analyzed people with severe OSA and those who do not show signs of any sleep disorders. The study showed that those with Obstructive Sleep Apnea had a higher protein burden, worse sleep efficiency, and spent less time in stage N3 sleep.
Stage N3 Sleep – Stage N3 sleep is a phase of deep sleep during the Non-REM phase of sleep. It typically lasts between 20 to 40 minutes and is the last phase before REM sleep. Stage N3 sleep is the time of sleep where your body heals and repairs itself.
This means people with Sleep Apnea spent less time sleeping when their brain was supposed to heal itself.
