Now, a new study indicates that there is, in fact, a connection.
The study is called “Association of sleep duration in middle and old age with incidence of dementia,” and it was published in the journal Nature Communications on Tuesday.
According to The New York Times, the study followed nearly 8,000 people in Britain over the course of 25 years, beginning when they were around 50 and continued into their 70s. The Times did point out that the numbers in the study were self-reported, especially when it came to the amount of sleep people were getting.
Per the Times, the study found that “those who consistently reported sleeping six hours or less on an average weeknight were about 30 percent more likely than people who regularly got seven hours sleep (defined as “normal” sleep in the study) to be diagnosed with dementia nearly three decades later.”

Here s what we re learning from brain scans.
Alzheimer’s disease is the most common cause of dementia. It slowly destroys memory, thinking and behaviors, and eventually the ability to carry out daily tasks.
As scientists search for a cure, we have been learning more about the genetic and environmental factors that can increase a person’s risks of developing late-onset Alzheimer’s disease and related dementias.
In particular, my colleagues and I in preventive medicine, neurology and gerontology have been looking at the role of outdoor air pollution.
Our early research in 2017 became the first study in the U.S. using both human and animal data to show that brain aging processes worsened by air pollution may increase dementia risk. Our latest studies show how older women who lived in locations with high levels of PM2.5 – the fine particulate matter produced by vehicles and power plants – suffered memory loss and Alzheimer’s-like brain shrinkage not seen in women living w
