Aim for 20 to 30 minutes, which puts you into the earliest stages of REM sleep
and lets you wake up easily, feeling refreshed.
When REM sleep
percentages decreased, the researchers discovered a 9 percent increase in the risk of dementia.
After adjusting for age and sex, researchers found links between both a lower percentage of REM sleep
and a longer time to get to the REM sleep
stage and a greater risk of dementia.
In this study, we explored the association between RSWA and SPs by manually quantifying chin EMG activity during REM sleep
, and then, we compared the results in the MSA-P group to those of the PD group to determine if any significant differences exist and whether these differences could be used to distinguish MSA-P from PD.
More than 80% of people who suffer from REM sleep
disorder eventually develop conditions such as Parkinson's disease and dementia, Dr Peever said.
We've evolved to go to bed between 8pm and midnight for the ideal ratio of light, deep and REM sleep
Some studies that have downplayed the effect of REM sleep
on memory consolidation citing the fact that people taking REM-suppressing drugs often do not report serious memory problems.
Brain waves during REM sleep
solidify memories in mice, researchers report in the May 13 Science.
We now know that our dreams are most prolific during REM sleep
, leading some to believe that dreams are simply a vivid yet pointless by-product of the increased brain waves during this stage of sleep.
Pets also give us an easy example of the transition from slow wave sleep to REM sleep
Pathophysiologic mechanisms in REM sleep
It was hypothesized that the alkaloid extract from MS may attenuate ethanol withdrawal without REM sleep
Participants also had significantly less rapid eye movement (REM) sleep following the LE-eBook condition, reflecting a lower average rate of accumulation of REM sleep
But when their REM sleep
was disrupted, they took 4 percent longer to complete the maze tests, the study found.
Presenting their research at the Society of Nuclear Medicine and Molecular Imaging's 2014 Annual Meeting, researchers are not sure why spontaneous and unexplained disturbance in REM sleep
should lead to a neurodegenerative disease like Parkinson's, but new longitudinal imaging data show a clear correlation between idiopathic REM behavior disorder and dysfunction of the dopamine transporter system involved in a wide range of vital brain functions, including memory and motor control.
