Tests and diagnosis

By Mayo Clinic staff

In addition to asking you a number of questions, your doctor may have you complete a questionnaire to determine your wake-sleep pattern and your level of daytime sleepiness. You may also be asked to keep a sleep diary for a couple of weeks, if you haven't already done so.

Your doctor will do a physical exam to look for signs of other problems that may be causing insomnia. Occasionally, a blood test may be done to check for thyroid problems or other conditions that can cause insomnia.

If you have signs of another sleep disorder, such as sleep apnea or restless legs syndrome, you may need to spend a night at a sleep center. Tests are done to monitor and record a variety of body activities while you sleep, including brain waves, breathing, heartbeat, eye movements and body movements.
