Scientist says poor sleep may lead to disease

Too little, too low-quality sleep has long been linked with a host of health issues, including weight gain, depression and strokes.

Jeffrey Iliff, an American Brain Scientist, said on Thursday in New York that findings have proved for the first time, that poor sleep can also leave brains vulnerable to Alzheimer's disease.

Iliff said if the amyloid of brain could not be properly cleared, a person would be put at a higher risk of Alzheimer's disease.
