What are the most common sleep disorders?

It’s hard to overstate the importance of a good night’s rest, complete with restorative sleep. Your body uses this time to rebuild, repair, regulate, and even create memories, so when your sleep rhythms are off, your entire state of being can be thrown out of balance.

There are over 80 sleep disorders that affect a person’s sleep, leading them to get either too much or too little, but the most common include:


In its simplest definition, insomnia is the inability to fall asleep or stay asleep, meaning you’re falling far short of the desired amount of rest (six to eight hours a night). About 50% of adults experience a bout of insomnia over the course of their lives, but chronic problems with insomnia can have a cumulative effect on your health and wellness.

Sleep apnea

Sleep apnea in its two different forms (obstructive and central) is a potentially serious disorder where you stop breathing many times throughout the night, interrupting your sleep over and over.


On the opposite end of the sleep disorder spectrum is narcolepsy, a condition that leaves you excessively sleepy during the day and prone to sudden and uncontrollable bouts of falling asleep.

How do you diagnose sleep disorders?

Sleep disorders are hard to diagnose because of the nature of the problem, namely that they occur at night, outside of regular office hours. It’s for this reason that Chandler Neurology and Sleep Disorders Associates offers a sleep clinic, where you can undergo a full evaluation of your sleep with a polysomnogram (PSG). During your PSG, Dr. Khan hooks you up to several different pieces of equipment that record, among other things, your:

  • Brain activity
  • Heart rate
  • Respiratory rate
  • Oxygen levels
  • Body movements

Undergoing a sleep study is one of the best ways for Dr. Khan to definitively diagnose your problem so that he can get you started on a treatment protocol.

How do you treat sleep disorders?

Since sleep disorders are vastly different, so, too, are the treatments. Once Dr. Khan gathers the necessary evaluations and makes a diagnosis, he sits down with you to review your options. For example, if you suffer from sleep apnea, he may recommend a CPAP device, which stands for continuous positive airway pressure.

If Dr. Khan diagnoses insomnia or narcolepsy, he recommends treatment that is much different and often entails behavior modification, prescription medications, and even counseling. Often, these disorders have a mental health component, or lead to one, which makes a multipronged approach the best choice.
