How can polysomnography help in the diagnosis of rapid eye movement (REM) sleep behavior disorder?

ANSWER

  • Polysomnographic video recording is the single most important diagnostic test in persons with REM sleep behavior disorder. This test is usually done in a sleep study center. You'll need to sleep at the center for this test, and you'll be wearing electrodes that will record information while you're awake and when you sleep. The test will monitor Electrical activity of the brain (electroencephalogram, or EEG)
  • Electrical activity of the heart (electrocardiogram, or ECG)
  • Movements of the muscles (electromyogram)
  • Eye movements (electrooculogram)
  • Respiratory movements There will also be continuous video recording to observe behaviors during sleep.
