Overview
A longitudinal observational neuroimaging study of individuals with Early Onset Alzheimer's disease during the prodromal phase, and matched control group - Ultrahigh Field MRI study at 7T
Description
This study aims to determine whether high resolution MRI at 7T and Quantitative Susceptibility Mapping (QSM) can demonstrate a specific pattern of iron overload in strategically important areas of brain as a sensitive marker of pathological Alzheimer's disease i.e. patients with subjective or mild cognitive impairment associated with Amyloid or tau pathological state in the cerebrospinal fluid.
