How is insomnia tied to dementia?

ANSWER

Research shows you're more likely to be diagnosed with dementia if you have primary insomnia. That's when your lack of sleep isn't caused by something else, like depression or drug use. Your chances of getting Alzheimer's disease go up if you can't sleep and you haven't reached age 40.
