PET of brain amyloid and tau in mild cognitive impairment

Article Abstract:

A study used in vivo cerebral imaging of two abnormal protein aggregates, [beta]-amyloid and tau, to study persons with mild cognitive impairment or Alzheimer's disease. Results revealed that 2-(1-{6-[(2-[F-18] fluoroethyl)(methyl)amino]-2-naphthyl}ethylidene)malononitrile-positron-emission tomography scanning can differentiate persons with mild cognitive impairment from those with Alzheimer's disease and those with no cognitive impairment.

Patterns of brain activation in people at risk for Alzheimer's disease

Article Abstract:

In a study involving 30 subjects aged 47 to 82 years, patients with a gene associated with Alzheimer's disease exhibited alterations in the brain function with no perceptible behavioral changes suggesting that a base-line level of brain activation can be a predictor of subsequent memory decline.
