New risk factor for Alzheimer's disease revealed: Are you getting a good night's sleep?


Extensive research over the past twenty years has repeatedly shown that Alzheimer's dementia is largely the result of a variety of lifestyle factors that promote the development of amyloid plaques and tau proteins in the brain that usher the onset of this dreaded disease. A diet high in processed carbohydrate and sugars, exposure to environmental and household pollutants and lack of physical activity have all been linked with development and progression of the disease. Now scientists have found that poor sleep patterns, as experienced by millions of aging adults, may be a powerful trigger for Alzheimer's disease.

Researchers from Temple University in Philadelphia, PA, reporting the results of their work in the journal, Neurobiology of Aging, have determined that people who experience chronic sleep disturbance, either through their work, insomnia or other reasons, could face an earlier onset of dementia and Alzheimer's. Prior research bodies have concluded that chronic sleep problems can inflame a number of health problems, ranging from cardiovascular disease and depression to cancer and diabetes.

Lack of restful sleep promotes brain tangle formation and early signs of Alzheimer's dementia

Lead study author, Dr. Domenico Pratico commented "The big biological question that we tried to address in this study is whether sleep disturbance is a risk factor to develop Alzheimer's or is it something that manifests with the disease." Using a transgenic mouse model known to simulate human neurological pathologies, the team examined the effects of sleep deprivation to determine the development of the two hallmark signs of Alzheimer's disease: amyloid plaques and tau protein tangles.

  1. Alzheimer’s bracelet and other forms of medical alert tags can be very useful for a person who is suffering from Alzheimer’. As Alzheimer’s symptoms increase, these people may forget who they are, how to speak, how to work with numbers, and how to perform even the most basic problem-solving tasks.
