dementias with a characteristic topographical distribution of the abnormal diffusion indices in DLB and AD. The ILF is responsible for visuospatial cognition and its impairment may be responsible for the clinical features of DLB. Diffusivity and anisotropy measurements are complementary to structural MRI, demonstrating that DTI is a valuable tool for characterizing the tissue abnormalities characteristic of Alzheimer disease and DLB.
