[Polygraphic recording of sleep in the aged. An EEG study]

Polygraphic recordings during sleep were performed on 18 elderly persons (age range: 64-100 years). These evaluations were carried out on two consecutive nights in our sleep laboratory. The purpose of this study was to supplement the existing evaluations that were performed in the past two decades and those performed in Anglo-American countries. In addition, we established our own standards for a sleep laboratory in our clinic, and arrived at a comparison with existing results and a critical evaluation of them.
