(WTHR) — If you struggle to get sleep every night, that could be an early warning sign of Alzheimer's.

That's according to a study out of Washington University in St. Louis.

Researchers found that older adults who get less deep sleep had more links to Alzheimer's.

The study also found that the total amount of sleep does not play a factor.

It's only the quality of the sleep that matters.
