Researchers get closer to preventing Alzheimer's disease

(New York, New York, July 6, 2006) A recent study directed by Mount Sinai School of Medicine identifies a faulty molecule in the brain found in cases of mild cognitive impairment (MCI). Researchers say this faulty molecule may be responsible for the progression of MCI to mild Alzheimer's disease (AD) dementia. The study, which appeared June 10th online in the journal Neurobiology of Aging, may lead to preventative treatments for AD.

An estimated 4.5 million Americans have Alzheimer's disease and presently there are no known cures or effective preventive strategies.

"Alzheimer's Disease is a growing health concern that affects millions of people, "says Giulio Maria Pasinetti, M.D., Ph.D., Professor of Psychiatry and Neuroscience, Director of the Neuroinflammation Research Center at Mount Sinai School of Medicine and lead author of the study. "We hope our research provides direction for preventative treatments to delay the onset of AD dementia by eliminating amyloid plaque-causing peptides in the brain."

People with AD exhibit elevated levels of beta-amyloid peptides that cause plaque buildup in the brain (the main characteristic of AD). In the earliest stages of Alzheimer's, beta-amyloid peptides are on the rise, especially in the two connected brain regions critical for memory functions-- the hippocampus and entorhinal cortex.

In this study, Dr. Pasinetti and colleagues at Mount Sinai School of Medicine in New York suggests one reason for that early increase of beta-amyloid peptides: an enzyme that breaks down beta-amyloid peptides, also referred to as an insulin-degrading enzyme (IDE), is not active in the brain in the cases at high-risk for developing AD. To assess possible changes in IDE during MCI, the investigators measured protein levels and enzymatic activity in postmortem brain tissue from 46 elderly subjects.


A loss of IDE activity has been previously shown to occur in sever
