What tests are done to diagnose non-24-hour-sleep-wake disorder?

ANSWER

Your doctor will ask about your medical history. He may suggest you keep a sleep diary for a few weeks, or even months, to help track your sleep patterns. You may also wear a sensor that tracks your movement and records your rest and activity patterns.

Blood, urine, or saliva tests over several weeks can check for signs that your body clock runs on a non-24-hour rhythm.

Together, the sleep diary and test results will help your doctor diagnose Non-24-hour sleep-wake disorder.
