Find the common sleep habits linked to increased Dementia Risk

sleep habits linked to Dementia

A recent international study conducted by researchers from China, Sweden, and the United Kingdom suggests a potential correlation between sleep patterns and the risk of developing dementia. The findings indicate that both the duration of sleep and bedtime may significantly influence dementia susceptibility.

The findings

The study, led by Dr. Rui Liu from Shandong University’s Shandong Provincial Hospital in Jinan, China, discovered that individuals sleeping more than eight hours a night faced a 69% higher risk of dementia. Additionally, those who went to bed before 9 p.m. instead of 10 p.m. or later were found to have a doubled risk of dementia.

The research, spanning an average follow-up period of 3.7 years with 2,000 initially dementia-free older adults in China, highlighted the need for monitoring cognitive function in older individuals reporting extended time in bed and advanced sleep timing, particularly in males aged 60 to 74.

Notably, the study emphasized the influence of cultural and socioeconomic factors on sleep habits and dementia risk. Older Chinese citizens in rural areas, with earlier bedtimes and shorter sleep durations, were found to be more susceptible to dementia than their Western counterparts.

While the study suggests a potential avenue for future research to explore whether modifying sleep habits could delay cognitive decline, the authors caution against definitive conclusions. They point out limitations such as self-reported sleep characteristics, the absence of data on sleep disorders like sleep apnea, and the relatively short follow-up duration.

Sleep problems and cognitive decline have been linked to demographic factors, including age, sex, and education. Moreover, there is a well-established genetic risk associated with short sleep duration and dementia.

The recommendations

In light of these findings, the researchers recommend consistent sleep patterns, advising individuals to maintain a regular sleep schedule, create a conducive sleep environment, avoid electronic devices in the bedroom, and adopt healthy pre-sleep habits like refraining from large meals, caffeine, and alcohol. Physical activity during the day is also recommended to facilitate better sleep quality.

As the study underscores the importance of sleep habits in cognitive health, further research may shed light on potential interventions to mitigate dementia risk through sleep-related adjustments.
