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.
