Memory Loss Affects More of The Brain Than Previously Thought
Alzheimer's disease and Memory Loss
Memory loss associated with early Alzheimer's disease (AD) may be linked to altered activity in several areas of the brain, according to a study in the July issue of Radiology.
For the first time, researchers at Duke University Medical Center in Durham, N.C., used a special, high-field- strength, functional magnetic resonance imaging (fMRI) scanner to study the brain activity of people with amnestic mild cognitive impairment (MCI), a precursor to Alzheimer's disease, and found altered functionality in both the frontal and temporal lobes of the brain. Previous studies looking at structural changes alone have shown evidence that brain atrophy in the earliest stages of
