Another study has shown a link between disrupted sleep patterns and Alzheimer’s disease.

Researchers at Washington University looked at 32 people who have what’s known as “preclinical” Alzheimer’s disease. They have a marker in their spinal fluid associated with Alzheimer’s, but they still don’t have any symptoms of dementia.

Wash U neurologist and sleep specialist Yo-El Ju says when she and her colleagues compared those people to 110 healthy controls, they found the two groups slept about the same amount.

If you're a student, you may have harbored the fantasy of learning lessons while you sleep. Who wouldn't want to stick on a pair of headphones, grab some shut-eye with a lesson about, say, Chinese history playing in his ears — and wake up with newly acquired knowledge of the Ming Dynasty?

Sadly, it doesn't work. The history lesson either keeps you from going to sleep, or it doesn't — in which case you don't learn it.
