| A new
study has found that the path and progression of
Alzheimers disease can be tracked through MRI scans, according
to neurologists in England.
study of 26 patients, researchers separated the participants
into three groups. One group had no symptoms, but did have
a family history of Alzheimers disease, while the other
two groups were in moderate to advanced stages of the disease.
course of evaluation, patients in each group were given at
least two MRIs to monitor structural changes.
reported in Proceedings of the National Academy of Sciences
that MRIs showed that the memory region of the brain experienced
rapid loss of tissue very early on, while tissue in other
areas of the brain disintegrated as the disease progressed.
concluded that their research could "provide insights
into disease progression in Alzheimer's disease and related
disorders, and may be useful for tracking progression in clinical
trials of new therapies."
