Sleep can be a common concern among those with multiple sclerosis. Possibly up to 60 percent of MSers struggle with some sort of sleep disturbance. Sleep apnea is a frequent contributor to this issue.
What is sleep apnea?
This is a condition that causes a person’s breathing to stop and start unpredictably during sleep. During those intervals (which may last for several seconds or more), the body is deprived of ample oxygen. An individual may gasp and awaken, or slightly stir and resume breathing. Each time this happens, it’s called an apnea, and it can occur many times each hour throughout the night.
Experts say approximately one in five
American adults may suffer from sleep apnea, although many may not be aware
they have it. (Often, it's identified after a sleeping partner complains enough about intense and sudden spurts of snoring that a person seeks medical advice for it.)
What are the symptoms of sleep apnea?
People with sleep apnea find themselves extra tired during the day. They might wake up with frequent dry mouths and nagging morning headaches.
What are the risks of sleep apnea?
Untreated sleep apnea can be deadly, or at least add to potentially fatal conditions. Some researchers claim it can take as much as 10 years off a person’s life, largely because it increases a person’s vulnerability to high blood pressure, strokes, and heart attacks. (This has something to do with decreased blood oxygen levels that occur during each apnea episode.)
How does sleep apnea play into MS?
Specialists have identified two types of apnea.
- Obstructive apnea occurs when the muscles in a person’s throat and nose relax (usually during sleep), blocking the airway and stopping breathing momentarily. This is the type that is commonly associated with loud, sputtering snoring and most often with obesity. Smoking is a risk factor as well.
- Central apnea occurs when the brain fails to direct the body to breathe for a short interval. This may be more of a neurological issue. (That concept sounds familiar to anyone with MS and how it can pay tricks on all sorts of body part and functions.)
MSers are widely regarded to be at higher risk for both kinds of apnea. Neuroscientists have pointed to reduced brainstem function issues as possible reasons for this, such as may be caused by demyelinating lesions that may be caused by MS over time.
Whether obstructive apnea, central apnea, or some combination of both, this sleep disorder wreaks havoc when it strikes someone living with MS. Even without MS, sleep apnea tends to make people extremely sleepy all day long, due to the diminishing of quality sleep overnight. MSers already face bouts of (or ongoing struggles with) a crushing fatigue that is nearly indescribable.
When sleep apnea prevents quality sleep, it considerably complicates this battle. The lack of rest can also aggravate memory loss, increase accident risks, lead to depression, and worsen diabetic symptoms (for MSers with that comorbidity).
Certain medications frequently used to alleviate MS symptoms may make sleep apnea worse. These include those prescribed for insomnia, pain, spasticity, and more.
What can be done about sleep apnea?
Once sleep apnea has been diagnosed (usually through an at-home of in-lab overnight sleep study, ordered by a neurologist or other physician), the patient will likely be prescribed treatment using a CPAP (continuous positive airway pressure) machine. This regulates breathing during sleep, piping humidified air into the person’s airway via a special mask. In many cases, sleep apnea may also be lessened somewhat when a person stops sleeping on his or her back.
It can take time and practice to adjust to CPAP treatment, especially the wearing and breathing through the mask while sleeping. (Trust me. It can take weeks or even months to get used to it!) But this adaptation has been shown to reduce sleep apnea episodes (as well as their duration), and eventually to improve restorative sleep and rest.
That’s worth plenty to an MSer.
