The main objective of the thesis is to evaluate the functionality of VDM by studying the brain vessels of the people who suffer from AD. In addition to VDM i have also calculated the arterial density and the arterial volume.
There are two main hypotheses in this thesis:
1- We hypothesize that the reduction in the micro vessels density in AD propagates to the larger vessels and can finally be detected by magnetic resonance imaging (MRI). Hence, we expect the density reduction in the arteries.
2- We further hypothesize that VDM in people with AD increases. In other words, since VDM depends on the distance of the vessels from each other, we expect an increase in the VDM if the vascular density decrease.
