Diagnosis

To diagnose your condition, your doctor will review your symptoms, go over your family and medical history, including your medications, and conduct a physical examination. Your doctor might order several tests to diagnose your condition, determine the cause of your condition and rule out other conditions.

• Epworth Sleepiness Scale. Your doctor may ask you to rate your sleepiness with this tool to help determine how sleep affects your daily life.
• Sleep diary. Your doctor may ask you to keep a sleep diary in which you log your daily sleep and wake times to help show your sleep amounts and pattern.
• Polysomnogram. In this test, you stay in a sleep center overnight. A polysomnogram monitors your brain activity, eye movements, leg movements, heart rate, breathing functions and oxygen levels as you sleep.
• Multiple sleep latency test. This measures your sleepiness and the types and stages of sleep you go through during daytime naps. This test is generally conducted the day after a polysomnogram.
