Imaging Studies

Routine radiographic, ECG, or EEG studies are unnecessary.


Other Tests

Polysomnography may be indicated. The hallmark of the various parasomnias is whether they occur during REM sleep, at the sleep-wake transition, or during slow-wave sleep. Polysomnographic studies demonstrate abrupt awakenings from REM sleep, usually during the second half of the night, prior to report of a nightmare. [3]
