• Different stages of sleep may differentially affect key features of Alzheimer’s disease.
• Our findings implicate REM sleep mechanisms as predictors of dementia,said expert.
• For the study, the team studied 321 participants over the age of 60.
• It is common for people with dementia to experience sleep disturbance.
• However, it is unclear if sleep disturbance occurs as a consequence of dementia.
• In addition,or if disturbed sleep is associated with the risk of dementia in the future, the researchers said.
• Further research is needed to determine whether REM sleep helps protect the brain from dementia.
• Or is sensitive to early brain changes that accompany dementia, the researchers suggested.
