Unique Study Sheds Light on Causes for Alzheimer's

A new study using PET scans on the brains of older individuals shows a three-fold higher risk of mild cognitive impairment (MCI) among those with elevated levels of amyloid-beta, a proteinaceous material associated with neurodegeneration. MCI is a known risk factor for Alzheimer's disease.

New meta-analyses explore link between Alzheimer's and amyloid

Two large meta-analyses in JAMA shed light on the link between Alzheimer s disease and amyloid beta (A-Î²). The key findings indicate that it is likely to take up to 30 years of amyloid deposition before clear signs of dementia are manifest but such deposits are not diagnostic.
