MR Diffusion Tensor Imaging (DTI) and Neuropsychological Testing for Neuronal Connectivity in Alzheimer’s Disease (AD) Patients

Alzheimer’s disease (AD), a neurodegenerative disorder associated with progressive functional decline, is initially diagnosed as a memory disorder accompanied by attentional and perceptual deficits. The perceptual deficits associated with AD include impaired visual motion processing with elevated thresholds for optic flow – the patterned visual motion seen during an observer self-movement.

A study was conducted to validate diffusion tensor imaging (DTI) as a new diagnostic tool for early AD.
