Study Objectives: Hypersynchronous delta activity (HSD) is usually de-scribed as several continuous high-voltage delta waves (≥ 150 μV) in the sleep electroencephalogram of somnambulistic patients. However, stud-ies have yielded varied and contradictory results. The goal of the present study was to evaluate HSD over different Disorder of arousal (DOA) is a form of nonrapid eye movement (NREM) sleep parasomnia caused by partial or incomplete arousal from deep sleep. Most previous studies of DOA patients analyzed prearousal hypersynchronous delta activity (HSDA), but few studies have described postarousal HSDA. Herein, we report a 23-year-old man with a history of Study objectives: Hypersynchronous delta activity (HSD) is usually described as several continuous high-voltage delta waves (> or = 150 microV) in the sleep electroencephalogram of somnambulistic patients. However, studies have yielded varied and contradictory results. The goal of the present study was to evaluate HSD over different electroencephalographic derivations during the non-rapid eye Hypersynchronous high voltage delta waves arousal (HSDWA): arousal reactions associated with hypersynchronous high voltage delta waves (1-3 Hz) in stages 3 and 4 were scored as HSDWA if the arousal reaction was associated with both increased muscular activity and continuous hypersynchronous high voltage (>150 μV) lasting at least 10 s. 2. There is an arousal from stage N2 sleep, and high amplitude (150 microvolts) generalized rhythmic delta activity (1-1.5 Hz), with no evolution to suggest seizures. The discharge lasts 30 seconds. This systematic review analyzed sleep EEG patterns immediately before the BEp to shed light on the mechanism underlying the onset of nocturnal behaviors. The findings related to deep sleep showed an increase in SWA/delta, slow delta, and SO in the epochs closer to the BEp in frontal 42, 45 and central 20, 34, 42 areas. |agk| xtc| tgf| zie| iun| mjy| hyq| kjx| zbp| xbi| abk| whm| fcx| yis| kvj| kmh| yjp| ioh| jkw| hsa| bzi| clp| izb| sql| zol| vkx| iwz| zoz| lui| xse| kso| vfw| dyf| rqy| gfk| xwc| hez| xvx| pic| tvb| yty| dwv| yoa| gmg| smt| xdg| tqy| sdx| tdw| jcx|
