A new study warns that getting less than five hours of sleep a night doubles the risk of dementia. Researchers at Brigham and Women's Hospital in Boston examined data from 2,812 American adults, as well as people aged 65 and over. ‘Very short’ sleep time was defined as five hours or less, and 7-8 hours was found to be twice the risk of dementia compared to the ‘recommended time’.

5 hours of sleep a night can double the risk of this serious illness

Do you sleep less than 5 hours a night?

New research confirms previous research that lack of sleep inevitably sets the stage for Alzheimer's disease, a form of dementia. This research does not investigate the cause behind the relationship, but the lack of proper rest can prevent the brain from removing toxins, leading to a decrease in brain function.

Fear of double risk of dementia

Researchers have identified an "urgent need" to identify specific recommendations for improving sleep in the elderly. Researcher Dr Rebecca Robbins says the results explain the relationship between lack of sleep and the risk of dementia and the importance of helping the elderly get enough sleep every day.

According to the World Health Organization, about 50 million people worldwide suffer from dementia and about 10 million new cases occur each year. Alzheimer's disease is the most common type of dementia and can contribute to 60-70% of dementia cases.

According to the UK Alzheimer's Society, more than 900,000 people in Britain live with dementia and the figure is estimated to be one million by 2024. The Sleep Foundation says that sleep disorders are more common in the elderly than in any other age group. There are many types of dementia, of which Alzheimer's disease is the most common.

Dementia is a global concern but is found in most affluent countries. There is currently no cure for dementia, but medications can slow it down. If reported at an early stage, more effective treatment can occur. Older people who don't get enough sleep have a 25 percent higher risk of stress and dementia, according to new research in China.
