Rapid Eye Movement (REM) Sleep Behavioural Disorder (RBD), Apnoea, and Long Time in Bed (TIB) are associated with a higher risk of cognitive disorders.
If you have been diagnosed with REM Sleep Behavioural Disorder (RBD), sleep apnoea, or consistently spend excessive time in bed (TIB) without sleeping, these are linked to a higher risk of cognitive decline. Seek medical evaluation and treatment for these conditions as part of your long-term brain health strategy.
We also identified four other types of sleep-related problems that showed significant associations with risk of cognitive disorders, including rapid eye movement sleep behavioural disorder (RBD, RR=1.90...), apnoea (RR=1.29...), and long TIB (RR=1.15...)
Why this rating
Based on fewer cohorts than insomnia/duration, with moderate credibility ratings (A- level).

More from this paper
- Insomnia and its components (daytime dysfunction, fragmentation, latency) are significantly associated with a higher risk of all-cause cognitive disorders and dementia.Good
- Sleep duration exhibits a U-shaped relationship with cognitive disorder risk, where both short (<4 hours) and long (>10 hours) nocturnal sleep durations are associated with elevated risk compared to optimal durations (5.6-7 hours).Good
