(a) N(PSG) (30 s per epoch) during Ndos sleep (epoch 555) immediately preceding the first sleep masturbation episode (epoch 556 – Fig. 1 b). EEG montage (channels 12–19) shows K-complexes and spindles. The electrooculogram (channels 7–8) indicates no rapid eye movements. The electrocardiogram (channel 11) shows no change in heart rate. Channels 20–23 represent the nasal/oral airflow, chest respiratory effort, abdomen respiratory effort and O2 saturation, which do not show any sleep apnea or oxygen desaturation during the epoch. (b) Onset of first sleep masturbation episode from N2 sleep (epoch 556). The spontaneous arousal began at 5: a.m. (solid arrow), and the masturbation started at 5: a.m. (hollow arrow). (c) Epoch 560 during the first episode of sleep masturbation. Light sleep persists during the masturbation. (d) The ending epoch (epoch 562) of the first sleep masturbation episode. The patient partially arises from the bed and stops masturbating at 5: a.m. (solid arrow). He then lays down on the bed at 5: a.m. (hollow arrow), and continues sleeping.
(a) Nocturnal PSG (29 s each epoch) from epoch 668 throughout the N3 sleep in the latest epoch quickly before the second bout of bed masturbation (epoch 669 – Fig. 2 b). That it epoch suggests totally uneventful N3 (slow-wave) sleep. (b) Start of next episode of sleep genital stimulation (epoch 669). Brand new spontaneous arousal began on 6: a beneficial.yards. (strong arrow), and genital stimulation come from the six: a.m. (hollow arrow). (c) One to epoch (epoch 671) in the 2nd episode of bed genital stimulation shows this new persistence regarding white sleep. (d) The brand new finish epoch (epoch 679) of your own second bout of bed genital stimulation. The in-patient averted masturbating and you may awakened during the 6: an excellent.yards. (strong arrow).
The patient got come SW 14 years before onset of sexsomnia, that’s a regular history to own sexsomnia growing decades after the onset of several other NREM parasomnia(s) ,
Hypnogram regarding quickly videos-polysomnogram portraying (horizontal bars) the initial occurrence (attack) regarding sleep genital stimulation growing out-of N2 sleep, accompanied by one minute occurrence (attack) regarding sleep genital stimulation emerging from N3 bed nearly an hour or so later on, extremely late from the bed duration.
Clonazepam, 0.5 milligrams in the bedtime was recommended, which enhanced the brand new SW however, did not suppress this new sleep self pleasure, once the seen from the army teams. The individual cures, as he planned to leave the newest armed www chatstep forces contained in this a couple months (once rewarding their responsibility). He expected that when returning family he’d resume a typical sleep-wake schedule with enough sleep cycle along with solution off their sleep masturbation and you may SW without needing medication.

step 3. Talk
There are lots of renowned results in such a case. Very first, bed masturbation was recognized of the vPSG since the an effective NREM parasomnia, growing throughout the one or two partial arousals, out-of N2 sleep and you will away from N3 bed, to the time and effort off sleep EEG pastime in masturbation. Both of the bed masturbation periods took place late on the sleep stage (duration #cuatro and #5 of 5 schedules). In addition to later introduction for the NREM parasomnia during the nocturnal sleep months indicates attention immaturity while sleeping from inside the a teenager that features starred a beneficial predisposing role having his parasomnia. The sleep genital stimulation (and reemergent SW) emerged in the context of an interrupted sleep-wake flow and you may bed deprivation regarding shift really works (as a good soldier), that are known triggers to have NREM parasomnia attacks inside the inclined some body .
