In REM sleep, the eyes twitch rapidly, there are changes in breathing and circulation, and the body enters a paralysed state known as
atonia. It happens in 90-minute-waves during sleep, and it's at this stage that our brains tend to dream.
Juvenile diabetes mellitus, optic atrophy, hearing loss, diabetes insipidus,
atonia of the urinary tract and bladder, and other abnormalities (Wolfram syndrome).
Only in a few PSG studies insomnia, mild sleep apnea, vivid dreams, loss of REM
atonia with and without REM behavioral disorder, and restless sleep were reported (2, 6, 7).
RBD is a parasomnia, characterized by loss of the
atonia that normally occurs during rapid eye movement sleep, and is associated with dream enactment behavior.
PNES is psychologically manifested in terms of situational and gradual onset, precipitated by stimuli, motor activity, limb movements, pelvic movement, tongue bite, ictal
atonia, cry and vocalization (Baslet, 2011).
They were associated with loss of chin and limb electromyography
atonia [12, 36, 37].
El mas frecuente es el trastorno conductual del sueno de movimientos oculares rapidos (MOR), que se puede presentar en todas las alfasinucleopatias y suele preceder en varios anos al inicio de la enfermedad; este trastorno se presenta porque la acumulacion de cuerpos de Lewy en el sistema reticular activador ascendente (SRAA) altera el proceso por el cual se produce la
atonia durante el sueno MOR; al perder la
atonia, el paciente <<actua los suenos>>; quien percibe los sintomas suele ser el companero, pues el paciente se golpea a si mismo o a otros o se cae durante el sueno (2,19,20).
Melatonin facilitates achieving better sleep for these patients by reducing the sleep-onset latency or by regulating sleep-wake times to coincide with the natural circulatory cycle, as well as reducing sleep episodes without muscle
atonia."
