Blood Sugar Holds Key to Preventing Alzheimers

Article excerpt

A SLOW, chronic reduction of blood sugar to the brain could trigger some forms of Alzheimers disease, U.S. researchers have said.

A study of human and mice brains suggests a reduction of blood flow deprives energy to the brain, setting off a process that produces the sticky clumps of protein researchers believe is a cause of the disease, they said.

The finding could lead to strategies such as exercise, reducing cholesterol and managing blood pressure to keep Alzheimers at bay, Robert Vassar and colleagues at Northwestern Universitys Feinberg School of Medicine in Chicago reported.

This finding is significant because it suggests that improving blood flow to the brain might be an effective therapeutic approach to prevent or treat Alzheimers, Mr Vassar, who led the study, said in a statement.
