CNN —Loss of slow-wave sleep as you age may increase your risk of developing dementia, according to a new study. Slow-wave sleep is the third stage of sleep, which is important for brain health. Each percentage decrease in slow-wave sleep per year was linked with a 27% increased risk of developing dementia and a 32% higher risk of Alzheimer’s disease dementia. The rate of slow-wave sleep loss accelerated from age 60, peaked from ages 75 to 80 and slowed afterward. “This is an important study yet again showing the impact of quality of sleep on a person’s risk of cognitive decline and dementia,” Isaacson said.
