Irregular and Reduced Deep Sleep Linked to Increased Dementia Risk, Studies Suggest

Improving sleep regularity and maintaining deep sleep could be potential preventative measures against dementia, according to recent research.

Irregular sleep patterns may increase the risk of dementia, according to a study published in the journal Neurology.
The study, conducted with 88,094 individuals, found that those with highly irregular sleep schedules were significantly more likely to develop dementia.
Improving sleep regularity to average levels may help prevent dementia, the study suggests.
Another study indicates that a 1% annual reduction in deep sleep among those over 60 increases dementia risk by 27%, suggesting the importance of maintaining deep sleep.
Both studies emphasize the potential of sleep regulation as a modifiable risk factor for dementia.
