We have developed and validated a non-invasive method to estimate the clearance of cerebrospinal fluid (CSF) from the brain. This study tests the hypothesis that reduced CSF clearance is predictive of a) future amyloid lesions, b) brain atrophy, and c) cognitive decline in healthy elderly adults or those with Mild Cognitive Impairment (MCI).
Measuring brain CSF clearance with novel, experimental imaging techniques may advance the understanding of Alzheimer’s disease (AD) progression at its earliest stages.
