Yanagisawa believes a simple amyloid blood test would enable recruitment for clinical trials of new drugs in a larger share of the population, as opposed to only those with access to advanced academic centers.

Amyloid buildup is a key pathological feature of Alzheimer's, and determining the degree to which someone's brain is riddled with the molecule is essential for designing effective clinical trials.
