“…For someone who puts such emphasis on science, the first author sells short the promise of new technology to advance our ability to do appropriate testing; for example the use of home video monitoring. Mweng et al 19 conducted a long term study of a SW comparing two nights of lab based videopolysomnography to thirty-six nights of home video monitoring over three months in three different locations. They found no significant difference in the frequency or duration of the SW events captured in the lab and at home.…”

“…The authors of the critique point out that the studies showing high reliability within subjects of the profi le of the R Cartwright and C Guilleminault spectral analysis sleep EEG wave forms, were not conducted on SW subjects and have not been shown to be stable over the extended period that usually occurs between an event that results in a criminal charge and a subsequent sleep study. However the several studies showing night-to-night reliability of delta power within normal individuals 11-14 even under sleep deprivation conditions, along with the several studies showing the significantly lower SWA in SW groups than in C even when no SW events occurred, 3,4,15 makes a low SWA a strong candidate to be a manifestation of the genetic vulnerability to abnormal delta arousals [16][17][18][19] and therefore likely to be a stable characteristic of sleep. Our article was one small step to encourage research needed to test stability of this within SW subjects over time.…”

W e thank the editor for the opportunity to respond to the letter by Pressman et al. 1 This is a critique of the article by Cartwright and Guilleminault 2 recently published in the Journal of Clinical Sleep Medicine. We address the salient points their letter raised: The aim of our article Was the method appropriate?We based the method for our study on the hypotheses proposed by Espa et al. 4 as the conditions necessary to precipitate an occurrence of a SWS parasomnia. "The occurrence of SWS parasomnia requires not only a SWS pressure increase but also SWS arousal enhancement." This is the push/pull model that Pressman argued was a theory that only Cartwright held in the debate he refers the reader to review. [5][6][7][8] He argued forcefully and repeatedly that SW only occurred with an increase of SWS and that this was the accepted wisdom. In fact the two variable model was stated earlier by Broughton et al. 9 in describing the Ken Parks case. "These typical polysomnographic features of sleepwalkers suggest the coexistence of both pressure for deep sleep (SWS) and of heightened arousal causing inability to sustain such sleep." This opposite pressure model was used in the Pilon et al. 10 study which succeeded in eliciting sleepwalking events in the laboratory by combining increasing pressure for SWS by a prior period of sleep deprivation and increasing arousals from sleep by delivering auditory tones during the recovery sleep. Neither of these manipulations was successful when applied singly. It was this opposite pressure model that we tested in the case study reported in our recent paper.The evidence presented in court supported both pressures were present in the defendant on the night of the event (he had a period of prior sleep deprivation and excessive caffeine intake during the day before the event). Thus the conditions for a SW event were present. Furthermore we pointed out that "the additional history of snoring and a mild breathing disorder validated in the PSG may be a contributing cause of his low SWA, high CAP rate and arousal into non-conscious acts when sleep deprived and over-caffeinated."Pressman et al. 1 raise the question whether a low SWA in the fi rst NREM cycle, measured after the fact (not months or years) but specifi cally in this case eight months after the incident, can be a reliable marker of a predisposition to SW. The authors of the critique point out that the studies showing high reliability within subjects of the profi le of the

“…Considering the widespread availability of video cameras and video phones, the analysis of homemade video recordings of DOA together with the historical features, could become an important tool for a correct diagnosis. The only report describing the use of home video for DOA was performed in 2013 by Mwenge et al In this study an adult sleepwalker monitored her behaviors during 36 nights documenting complex prolonged episodes not usually observed during ambulatory VPSG and providing the tools for differentiating SW from seizures (non-stereotyped vs. stereotyped behaviors) (Mwenge et al 2013).…”

Disorders of Arousal in adults: new diagnostic tools for clinical practice

Disorders of Arousal (DOA) are mental and motor behaviors arising from NREM sleep. They comprise a spectrum of manifestations of increasing intensity from confusional arousals to sleep terrors to sleepwalking. Although DOA in childhood are usually harmless, in adulthood they are often associated with injurious or violent behaviors to the patient or others. Driving motor vehicles, suspected suicide, and even homicide or attempted homicide have been described during sleepwalking in adults. Furthermore, adult DOA need to be differentiated from other sleep disorders such as Sleep-related Hypermotor Epilepsy or REM Sleep Behavior Disorder. Although many aspects of DOA have been clarified in the last two decades there is still a lack of objective and quantitative diagnostic criteria for DOA. Recent advances in EEG analysis and in the semiological characterization of DOA motor patterns have provided a better definition of DOA diagnosis. Our article focuses on the DOA diagnostic process describing accurately the newest DOA clinical, EEG and videopolysomnographic tools in order to aid clinicians in DOA assessment.
