What are the different types of sleep disorders? What are the symptoms of sleep disorders?
Though over 70 exist,3 here are some of the top sleep disorders and their symptoms.
1. Obstructive Sleep Apnea (OSA)
Your body is pretty good at making sure you make it through the night – that you’re breathing and breathing right. That’s why when you have sleep apnea, your body is constantly waking you up due to the disrupted breathing events that happen with this disorder.
What is sleep apnea?
Sleep apnea is a disorder in which the muscles in the throat relax to the point of collapse, restricting airflow. This causes breathing to become shallow and even stop for seconds or minutes at a time, depriving the body and brain of oxygen. The lack of deep sleep can cause significant fatigue and elevate the risk for serious health problems. Most people with sleep apnea are unaware they have it. The most common treatment to regulate breathing is a Continuous Positive Airway Pressure (CPAP) device.
There are several types of sleep apnea, though obstructive is most common:
- Obstructive: collapse of the soft tissue at the back of the throat
- Central: the brain fails to send a signal to the muscles to breathe
- Complex: a combination of these two types of apneas
Some symptoms of sleep apnea:
- Snoring
- Gasping for air or choking
- Waking frequently
- Waking with dry mouth or headaches
- Daytime tiredness
- Weight gain
- Loss of focus
- Depression
Dangers of sleep apnea:
- High blood pressure
- Cardiovascular disease
- Increased risk for stroke, diabetes and obesity
- Decreased quality of life
- Memory problems
- Increased risk of car accidents
What to do if you think you have sleep apnea? Find out if this is what’s keeping you up at night with a sleep test. We have helpful resources about what is a sleep test, how to set up a sleep test, and what to expect. It’s also important that you find a sleep medicine specialist to talk through treatment and options.

2. Upper Airway Resistance Syndrome (UARS)
Similar to sleep apnea, UARS can often be mistaken for it. Sometimes CPAP is even prescribed. If harmless (only noisemaking) snoring is on one end of the sleep disordered breathing spectrum, and sleep apnea on the other, UARS is somewhere in the middle. The main difference between the two is that while breathing quality is diminished, UARS does not (or rarely does) cause apneas, or, pauses in breathing. It can, however, lead to sleep apnea.
Some symptoms of UARS:
- Snoring
- Waking frequently
- Difficulty going to sleep/staying asleep
- Chronic insomnia
- Excessive daytime tiredness
A sleep study may be necessary for diagnosis and to find the right level of treatment, which could include CPAP therapy.
3. Periodic Limb Movement Disorder (PLMD) and Restless Leg Syndrome (RLS)
PLMD is when the limbs involuntarily move repeatedly throughout the night, which can lead to frequent awakenings, non-restorative sleep, and daytime fatigue. It’s often associated with restless leg syndrome, which occurs during waking hours.
4. Narcolepsy
This disorder often runs in families, though it’s relatively rare. It presents as a serious urge to sleep, often without warning or ability to resist. Diagnosis and treatment involve working closely with a sleep medicine professional.
5. Other sleep disorders
REM sleep behavior disorder, insomnia, and circadian rhythm disorder are other examples of sleep disturbances that have medical symptoms and treatments. These disorders include symptoms like abnormal activity during sleep, inability to initiate sleep, and sleep phase delays similar to jet lag.
With all sleep disorders, correct diagnosis is key to getting the right treatment. The best thing to do if you exhibit symptoms and suspect you’re not sleeping properly is to schedule a sleep test and work with a sleep medicine specialist. The positive impact treatment has on sleep can make all the difference in your life.
