Sleep Medicine

Expert care for sleep apnea, insomnia, daytime sleepiness, narcolepsy, restless legs syndrome, REM sleep behavior disorder, hypersomnia, and more.

Why Sleep Matters

​Sleep is not just rest—it’s essential for your body and mind to heal, regulate, and function optimally. Poor sleep can affect your immune system, hormones, weight, mental health, and even increase your risk for heart disease, stroke, and diabetes. Chronic sleep issues can silently chip away at your quality of life and overall health.

 

We believe restorative sleep is the foundation of good health. That’s why we take a comprehensive, personalized approach to uncover the root causes of your sleep problems and guide you toward lasting solutions.

Comprehensive Sleep Care

From diagnosis to treatment and follow-up, our team provides compassionate, comprehensive, and personalized care to help you achieve restorative sleep.


We treat:

  • Obstructive sleep apnea

  • Insomnia (difficulty falling/staying asleep)

  • Narcolepsy and hypersomnia

  • Restless legs syndrome & periodic limb movement disorder

  • REM sleep behavior disorder

  • Nightmares, sleepwalking, and other parasomnias

Sleep Diagnostics

We use advanced diagnostics like at-home sleep apnea tests and in-lab polysomnography to accurately assess your sleep patterns.

Polysomnography

A polysomnography, or PSG, is an overnight sleep study conducted in a specialized lab. It comprehensively monitors your sleep, recording brain waves, eye movements, breathing, heart rate, and muscle activity. This allows us to accurately diagnose a wide range of sleep disorders.

Home Sleep Study (HSAT)

A home sleep study is a convenient option for diagnosing certain sleep disorders, such as sleep apnea. You'll use a portable device to monitor your breathing and oxygen levels while you sleep in your own bed. We'll then analyze the data to determine if you have a sleep-related breathing problem.

MSLT

The Multiple Sleep Latency Test, or MSLT, is a daytime study used to measure how quickly you fall asleep. It's often used to diagnose conditions like narcolepsy and excessive daytime sleepiness. During the test, you'll take several scheduled naps throughout the day, and we'll record how long it takes you to fall asleep.

CPAP and Other Devices

We offer expert help with troubleshooting your CPAP or BiPAP device to maximize your comfort during sleep. We also provide alternative therapies for sleep disorders, including positional therapy, oral appliances, and EPAP devices like the Bongo Rx.

Cognitive Behavioral Therapy for Insomnia (CBT-i)

CBT-I is a highly effective, evidence-based treatment for chronic insomnia. Unlike medications, CBT-I addresses the underlying thoughts, behaviors, and habits that interfere with sleep. It helps retrain your mind and body to fall asleep more easily, stay asleep longer, and wake up feeling rested.

At the Clinic of Dr. Harrison Hasanuddin, we offer personalized CBT-I sessions tailored to your sleep patterns and lifestyle. Treatment typically includes:

  • Identifying and changing unhelpful thoughts about sleep

  • Optimizing bedtime routines and wake-up schedules

  • Improving sleep efficiency through stimulus control and sleep restriction

  • Managing nighttime awakenings

  • Establishing a healthy sleep environment

 

CBT-I is recommended as first-line therapy by the American College of Physicians and American Academy of Sleep Medicine (AASM) is effective even for those who have struggled with sleep for years.
