Chronic insomnia may raise dementia risk by 40%, lead to 3.5 years faster aging
Insomnia is a sleep disorder where a person has trouble falling and staying asleep. Past studies have linked insomnia to an increased risk for a number of health concerns, including cognitive decline, dementia, and Alzheimer’s disease. A new study found that people with chronic insomnia may be at a greater risk of developing dementia or mild cognitive impairment than those with non-chronic insomnia, associated with faster brain aging.
