Sleep Medicine

Leading the Way in Sleep Medicine and Treating Sleep Disorders

Our bodies are built for an average of eight hours of sleep and 16 hours of wakefulness. However, more than 40 million Americans suffer from disorders of sleep that prevent them from enjoying optimal sleep. Sleep disorders such as obstructive sleep apnea, sleep fragmentation, and circadian rhythm disorders can have drastic consequences during wakefulness and can adversely affect cardiovascular and neurologic function and overall quality of life. Sleep disorders can have social costs as well, including poor job performance and accidents on the job, at home and at the wheel.

Historically, it was thought that a bad night’s sleep was something people just had to live with, even if it happened night after night. Awareness is growing, however, and we now understand that many sleep disorders have underlying causes, and can be treated successfully.

Accredited by the American Academy of Sleep Medicine, North Shore-LIJ Health System's Sleep Medicine services provide state-of-the-art diagnostic and treatment facilities, enhanced with extensive medical resources and research.

Our Sleep Medicine team is composed of the region's leading sleep disorders specialists, clinicians and researchers, all of whom are sought-after speakers at regional and national sleep disorders conferences.

Under the direction of Dr. Harly Greenberg, Medical Director of the North Shore-LIJ Sleep Disorders Center, the Sleep-Wake Disorders Program has grown to a full-service program serving Long Island and Queens. Dr. Greenberg is one of the few accredited polysomographers in the area. Polysomography, or sleep study, measures sleep cycles and stages by recording these activities:

  • Air flow in and out of the lungs during breathing
  • Blood oxygen levels
  • Body position
  • Brain waves (EEG)
  • Breathing effort and rate
  • Electrical activity of muscles
  • Eye movement
  • Heart rate

Ongoing sleep disorders research and clinical trials at Sleep Medicine services focus on areas such as:

  • Insomnia
  • Sleep fragmentation — arousals or awakenings during sleep
  • Sleep deprivation
  • Circadian rhythm sleep disorders — sleep disruptions in a person's natural sleep-wake cycle
  • Cardiovascular effects of obstructive sleep apnea (OSA). OSA is a common disorder in which people have one or more pauses in breathing or shallow breaths while they sleep.
  • Effects of the CPAP machine on quality of life. CPAP stands for "Continuous Positive Airway Pressure." The machine helps a person who has obstructive sleep apnea breathe more easily during the night.

In the United States sleep apnea is a very common sleep disorder that affects over 12 million Americans, according to the National Institutes of Health. The majority of people who suffer from it don't know they have it, because sleep apnea symptoms are varied and can easily be attributed to other conditions.
