Sleep Medicine Q & A


What are the different types of sleep disorders?

There are about 80 types of sleep disorders, all of which lead to sleep deprivation that undermines your quality of life. Lack of sleep also significantly impacts your overall health.

Dr. Ewaida treats all types of sleep disorders, so these are just a few examples of those frequently found in his patients:

  • Insomnia: Difficulty falling asleep or staying asleep
  • Obstructive sleep apnea: Temporarily stopping breathing while you sleep
  • Narcolepsy: Daytime sleepiness that makes you suddenly fall asleep
  • Restless legs syndrome: Unpleasant sensations in your legs and an irresistible urge to move your legs
  • REM behavior disorder: Move and act out your dreams during REM (rapid eye movement) sleep

Sleep disorders certainly cause daytime sleepiness, but their symptoms extend beyond exhaustion. They can affect your memory, make it impossible to concentrate and make you feel anxious.

Sleep deprivation also affects your overall health. Long-term consequences of disrupted sleep include cardiovascular disease, weight gain, and hypertension. You’re also at risk of falling asleep while driving.

What causes obstructive sleep apnea?

Obstructive sleep apnea (OSA) occurs when you briefly but frequently stop breathing while you sleep. Your breathing may stop for seconds or minutes, then it starts again when your brain nudges you awake just enough to take a breath.

OSA occurs when muscles relax, allowing your tongue and other soft tissues to fall back toward your throat and block the flow of air.

The top symptoms of OSA are loud snoring, suddenly gasping when your breathing restarts, and daytime fatigue.  

What is narcolepsy?

Narcolepsy is a sleep disorder that causes overwhelming daytime sleepiness, but your fatigue is not due to sleeping poorly at night or other sleep disorders.

People with narcolepsy fall asleep suddenly and at unusual or inappropriate times. After waking, you may feel refreshed, but you’ll suddenly fall asleep again a few hours later.

Most people with narcolepsy also experience cataplexy, which is a sudden muscle weakness or feeling like you’re paralyzed. Cataplexy is often triggered by laughing, excitement, or other strong emotions.

How are sleep disorders diagnosed and treated?

Some sleep disorders may be diagnosed based on your symptoms, but most require a sleep study. During a sleep study, your breathing, muscle movement, heart rate, and eye movement are recorded while you sleep.

Treatments are just as diverse as the many types of sleep disorders. For example, your treatment may include behavioral changes, medications, and breathing or oral devices.
