title: Sleep apnea and nocturnal myoclonus in elderly persons in Vilcabamba, Ecuador.
abstract: Four men (M age 90.5 years) and four women (M age 91.2 years) in Vilcabamba, Ecuador (a community noted for people with extreme longevity) volunteered for sleep recordings using four-channel Medilog portable cassette recorder. Of the eight physically healthy persons recorded, only one man displayed sleep apnea syndrome. No nocturnal myoclonus was observed. Low incidence of sleep apnea of elderly persons in Vilcabamba may be due to a low barometric pressure and/or lack of drug abuse.
