Conditions We Treat

Restless Leg Syndrome

An irresistible urge to move your legs, especially in the evenings. This usually occurs when sitting or lying down and can often interrupt sleep.

Circadian Rhythm Disorder

A group of sleep disorders that cause a disruption in the timing of sleep. This can include a delayed sleep phase, advanced sleep phase and irregular sleep-wake rhythm disorder.

Hypersomnia (Excessive Daytime Sleepiness)

Tiredness or daytime sleepiness that can result from restless leg syndrome, insomnia, idiopathic hypersomnia, narcolepsy, circadian rhythm disorder or other sleep issues.


Actions that disrupt sleep like abnormal movements, sleep talking, and emotions.

Obstructive Sleep Apnea

A chronic medical condition that can cause you to stop breathing repeatedly throughout the night. If left untreated, it can cause high blood pressure, heart disease, stroke, mental health problems, snoring and several other medical problems.


Patients with Insomnia have persistent problems falling and staying asleep. The quality and amount of sleep has a major effect on someone’s general health, including issues like depression, blood pressure control, and alertness and concentration.

Central Sleep Apnea

A disorder in which your breathing repeatedly stops and starts during sleep because of respiratory center suppression in the brain.


Narcolepsy results from a decrease in wake-promoting chemicals in the brain causing excessive daytime sleepiness and cataplexy episodes ( loss of muscle tone). Insomnia, sleep paralysis and sleep onset hallucinations are also observed in patients with Narcolepsy.

Home Sleep test


A home sleep test is used for the evaluation of suspected sleep apnea only, and is done with a small device that records airflow, breathing pattern, heart rate, breathing effort and oxygenation. If a home sleep test is suggestive of sleep apnea, treatment can be initiated based on home sleep test results. If the home sleep test has inadequate data, or does not reveal sleep apnea diagnosis, an in-lab polysomnogram is required for further evaluation.

We use very small and convenient ResMed ApneaLink Air and CleveMed SleepView home sleep testing devices at our sleep lab.

Diagnostic Polysomnogram (In-lab sleep study)

Diagnostic polysomnogram is the gold standard test used for the evaluation of suspected sleep apnea, REM behavior disorder (dream enactment), and periodic limb movement disorder.

Overnight diagnostic polysomnogram is done in the sleep lab and conducted by experienced sleep technicians. Multiple electrodes are placed to monitor brain waves (EEG), eye movements, muscle activity, heart rate, heart rhythm, leg movements, and other sleep parameters.

Titration Study

Titration study is used to determine the effective treatment pressure from CPAP or BiPAP for the treatment of sleep apnea. We use nasal pillows, nasal masks or full-face mask during titration study, and the pressure setting from CPAP or BiPAP is gradually adjusted by the sleep technician based on airflow recording in monitored setting in the sleep lab. Multiple electrodes are also placed to monitor brain waves (EEG), eye movements, muscle activity, heart rate, heart rhythm, leg movements, and other sleep parameters. We also conduct titration studies using oral appliance to determine effective setting on the oral appliance to treat sleep apnea effectively.


Multiple Sleep Latency Test (MSLT)

This study is performed for the evaluation of excessive daytime sleepiness if there is a strong clinical suspicion for narcolepsy or idiopathic hypersomnia. MSLT is done on the day after an overnight polysomnogram. After the polysomnogram, the patient is given an opportunity to nap for 15-20 minutes. During this time, brain activity is monitored to find out how quickly you are falling asleep and how quickly you are going into REM sleep.
