Bergmann, Högl and Ambra have put together an excellent review on the neurophysiological aspects of REM parasomnias, including their definition, clinical characteristics and possible neuroanatomical correlates. These include recurrent isolated sleep paralysis, nightmare disorder and REM sleep disorder behaviour. The diagnosis of the latter is important since it is often a prodromal symptom of synucleinopathies, a subgroup of neurodegenerative diseases. REM parasomnias are well characterized with video-polysomnographic recordings (required for diagnosis), including electroencephalography (EEG), electrooculography (EOG) and electromyography (EMG) signals.
