Sleep Disorder Center at VMC

What is a sleep disorder?

More than 40 million Americans suffer from a sleep disorder, such as snoring or insomnia. Problems with sleep can cause devastating results. Types of sleep problems include:

  • Snoring – Snoring can be a symptom of obstructive sleep apnea.
  • Obstructive Sleep Apnea – A blockage in the back of the throat that results in snoring and pauses in breathing during sleep.

  • Restless Leg Syndrome – Characterized by uncomfortable sensations in the legs or feet before going to sleep. Once asleep, this causes brief leg movements.
