Study: Grapes may contain nutrients that prevent Alzheimer’s disease
July 18, 2011
Alzheimer's disease can cause confusion and loss of spacial awareness, which increases the risk of injury in adults who have been diagnosed. Scientists believe that they are very close to finding a cure for this form of dementia. Until this happens, older adults can protect themselves with personal emergency response systems, which can send out a medical alert if a senior is injured.
Antioxidants in grapes may contain the key to preventing Alzheimer's disease. Researchers at the Mount Sinai School of Medicine recently studied the effect of the grape seed polyphenols on the prevention of the development of a specific peptide in the brain, which causes the neurotoxicity that is associated with Alzheimer's disease.
"Since naturally occuring polyphenols are also generally commercially available as nutritional supplements and have negligible adverse events even after prolonged periods of treatment, this new finding holds significant promise as a preventative method or treatment," said Dr. Giulio Pasinetti, the lead researcher.
The researchers gave polyphenol extracts to mice who were genetically altered to develop dementia, and they found that the treatment significantly reduced the prevalence of the peptide. They believe that if they can identify at-risk individuals early enough, the grape seed extract could prevent the development of Alzheimer's disease.
