The full-time staff of physicians and sleep specialists utilize the latest technology for diagnosing and treating sleep disorders in adults.

Evaluation and diagnosis should only be performed by a team of professionals led by a physician with specialized training in sleep disorders.

The sleep test most patients undergo is called a polysomnogram. This test determines whether there are any abnormalities in your quality of sleep, including breathing abnormalities or limb movements. In most cases, the test is performed during a 10-12 hour overnight period.

Referral Procedures

Typically, patients schedule appointments for initial consultation with their primary care physician (PCP). When necessary, the PCP will request testing through the sleep study staff.

Private consultations are available by appointment with Michael Newnam, M.D., board certified in sleep medicine, on the second Thursday of each month.

Sleep Disorders Treated

Sleep Apnea

Often associated with loud snoring, snorting and gasping for breath, these are periods of uninterrupted breathing during sleep. Sleep apnea can result in daytime sleepiness which can lead to difficulties at work, cause automobile accidents, memory and other intellectual difficulties and depression. Sleep apnea can lead to worsening high blood pressure and is associated with a higher incidence of heart attacks and strokes.

Restless Legs Syndrome/Periodic Limb Movement Disorder

Symptoms include uncomfortable sensations in the legs near sleep time, leading to an irresistible need to move the legs, resulting in interference with sleep. Legs and arms may move or jerk involuntarily during sleep. You may experience excessive sleepiness, insomnia, or both.


Narcolespy is a brain disorder that causes uncontrollable bouts of excessive sleepiness. Patients with narcolepsy may lose muscular strength suddenly when emotionally upset or when laughing. In addition, they may experience vivid hallucinations as they fall asleep.


At least 15 percent of the population suffers from insomnia – difficulty falling or staying asleep – every year. Insomnia can be caused by a number of medical or behavioral factors such as stress, anxiety, depression, sleep apnea, restless legs/periodic limb movements during sleep, alcohol, caffeine, drugs or poor sleep habits.
