Two significant barriers have limited the development of effective treatment of Alzheimer’s disease. First, for many cases the aetiology is unknown and likely multi-factorial. Among these factors, hypercholesterolemia is a known risk predictor and has been linked to the formation of b-amyloid plaques, a pathological hallmark this disease. Second, standardized diagnostic tools are unable to definitively diagnose this disease prior to death; hence new diagnostic tools are urgently needed. Magnetic resonance imaging (MRI) using high field-strength scanners has shown promise for direct visualization of b-amyloid plaques, allowing in vivo longitudinal tracking of disease progression in mouse models. Here, we present …
