- In Alzheimer's patients, the amyloid beta protein somehow goes off track and clumps together in sticky plaques that destroy healthy brain tissue.

- The treatment targets the buildup of lumps of protein fragments called amyloid beta peptides, which is the dominant theory of the cause of Alzheimer's.
