- Abstract:
- In 19 patients with cerebral infarctions in the middle cerebral artery territory, investigations of sleep using a mobile EEG recording system were performed. Sleep was found to be markedly altered compared to a normal group. Although an increase of time in bed and sleep period time was observed, total sleep time did not rise in a parallel manner, so that a distinct reduction of the sleep efficiency index was found. This increase of quantitative parameters was particularly caused by a higher amount of NREM time, whereas REM sleep was found to be deeply suppressed. Regarding the different NREM sleep stages, stage 0 (time spent awake during the night) and stage 1 had increased, whereas stage 4 was reduced. Interhemispheric differences were noticed referring to the sleep period time, which was found to be increased particularly in right-sided infarctions (because of an increase of NREM time) and a reduction of REM sleep in lesions of the right hemisphere (worsening of the REM to NREM ratio). Slow-wave sleep (stage 4), on the contrary, was found to be decreased in infarctions of the left hemisphere. These results support the hypothesis of a REM-inducing and regulating function of the right hemisphere and will lead to a new understanding of sleep-controlling mechanisms.
