Sleep quality may increase dementia risk: Latest evidence

Medical News Today has recently covered several pieces of research that support a strong link between sleep and dementia risk. One of these studies, using MRI scans, found that people with a weaker glymphatic system—which clears toxins from the brain during sleep—have a higher risk of dementia. Another study found that moderate to severe obstructive sleep apnea may raise the risk of tiny brain bleeds, which could increase the chances of dementia and stroke. And another study suggested that people with chronic insomnia may be at a greater risk of developing dementia or mild cognitive impairment, which has been linked to faster brain aging.

5 healthy habits may help keep the brain younger, even with chronic pain

A new study from researchers at the University of Florida examined brain aging in a group of middle-aged and older adults, many of whom had chronic pain. ‘Brain age’ refers to how old the brain appears on MRI scans, which the scientists compared to the participants’ actual age. The researchers learned that people who had healthier lifestyle behaviors were more likely to have a younger brain age, which was true even in people with chronic pain.

Between sleep and exercise, choose sleep, research suggests

Studies have shown that physical activity and sleep influence each other over 24 hours, suggesting a need to optimize both to reduce the long-term risks of morbidity and mortality. A large, multinational study found that fewer than 13% of participants simultaneously met the recommended 8,000 daily steps and 7-9 hours of sleep. The study found that sleep duration influenced the number of steps the next day, but the number of steps had little impact on sleep quality or quantity. This study highlights the need for interventions that simultaneously increase sleep and physical activity levels, as the importance of adequate sleep is often overlooked.
