Alzheimer disease is a neurodegenerative disease or a decline in brain function. Memory decline until the patient is unable to fend for himself.
Researchers from Washington University School of Medicine in St. Louis found that the brains of people with poor sleep patterns have more buildup of amyloid plaque, clumps of protein that is a hallmark of Alzheimer's disease.
The research team monitored the sleep patterns of 100 healthy volunteers aged 45-80 years during 14 nights. Half of the participants had a family history of Alzheimer's disease.
In the study, researchers set up an instrument to measure the participants slept for two weeks. Researchers also analyzed the results of questionnaires and diaries of participants.
Researchers found people woke up to more than five times per hour and those who spend less than 85 percent of their time in bed to not really sleep, more likely to have amyloid plaques in the brain than those who sleep easily.
"Impaired sleep quality associated with the buildup of amyloid plaques, a marker characteristic of Alzheimer's, in the brains of healthy people who previously had no memory impairment."
