Changes in brain connections visible on MRI that represents an imaging biomarker of Alzheimer's disease was observed in a new study. The study presented at the annual meeting of the Radiological Society of North America (RSNA), researchers looked at the brain's structural connectome, a map of white matter tracts that carry signals between different areas of the brain.
Study co-author Jeffrey W. Prescott, M.D., Ph.D., radiology resident at Duke University Medical Center in Durham, N.C., said that the structural connectome provided them with a way to characterize and measure these connections and how they change through disease or age.
Alzheimers Disease
Alzheimer''s disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

Prescott and colleagues analyzed results from 102 patients enrolled in a national study called the Alzheimer's Disease Neuroimaging Initiative (ADNI) 2. The patients had undergone diffusion tensor imaging (DTI), an MRI method that assesses the integrity of white matter tracts in the brain by measuring how easy it is for water to move along them.
Prescott said it was known that water prefers moving along the defined physical connections between regions in the brain, which makes DTI a great tool for evaluating the structural connectome and the results showed a strong association between florbetapir uptake and decreases in strength of the structural connectome in each of the five areas of the brain studied.

Ageing is referred to the accumulation of changes that brings a person closer to death.
Jeffrey R. Petrella, M.D., professor of radiology at Duke and senior author on the study suggested that amyloid deposition in the gray matter affects the associated white matter connections, which are essential for conducting messages across the billions of nerve cells in the brain, allowing for all aspects of mental function.
