In-House Sleep Study

What is an In-House Sleep Study?

An in-house sleep study is an overnight diagnostic test performed in a medical facility or sleep center, rather than at home, to evaluate sleep disorders. It is also called polysomnography.

What does an In-House Sleep Study involve?

During the study, you sleep in a private, monitored room while specialized equipment records:

• Brain activity (EEG)
• Eye movements
• Heart rate and rhythm
• Breathing patterns and oxygen levels
• Muscle activity and body movements

What conditions can be diagnosed by an In-House Sleep Study?

In-house sleep studies are considered the gold standard for diagnosing conditions such as:

• Obstructive and central sleep apnea
• Narcolepsy
• Periodic limb movement disorder
• Parasomnias (sleepwalking, night terrors)
• Unexplained excessive daytime sleepiness

How does an In-House Sleep Study differ from a home sleep test?

• More comprehensive: Measures more physiologic data
• Medically supervised: Technicians monitor you throughout the night
• More accurate for complex cases: Especially when symptoms are severe or unclear

When is an In-House Sleep Study recommended?

An in-house sleep study is typically advised if:

• Symptoms are complex or severe
• A home sleep test was inconclusive
• Neurologic or movement-related sleep disorders are suspected

What Are the Benefits of an In-House Sleep Study?

Key benefits include:

• Most accurate method for diagnosing sleep disorders
• Continuous medical supervision
• Comprehensive data collection
• Ability to diagnose complex or rare sleep conditions
