This technology may become a help to identify Alzheimer’s disease. The research by Duke University Medical Center researchers, used an imaging technology to identify a new marker on the brain that may help identify those at greatest risk for cognitive decline and the development of Alzheimer’s disease.
The uses of a functional magnetic resonance imaging (fMRI) on people with MCI can track regions of the brain that become active or inactive when participating in tasks that involve memory. The results of this study, published in PLoS One, focus on an area of the brain known as the posteromedial cortex, which has recently been implicated in personal memory.
They said, the posteromedial cortex may be our brain’s ‘cruise control’ that normally deactivates when we are trying to remember things, so resources can be sent to other areas of the brain that encode memories. However, in people with mild cognitive impairment or Alzheimer’s disease, the deactivation does not happen and the posteromedial cortex remains active.
