These changes are thought to result from damage to sleep-regulating areas in the brain . Alzheimer patients tend to spend less time in both REM rapid eye movement sleep , in which most dreaming occurs , and non-REM NREM sleep . But they show the greatest reduction in so-called slow-wave sleep SWS â a stage of non-dreaming deep sleep ,
