I watched a couple of Dr. Amen's TedTalks a few days ago. He listed the primary disease associated causes of Alzheimer's - heart disease, cancer, diabetes, depression and high blood pressure. Leronlimab can fix 4 out of the 5 and possibly all 5. In addition to treating ongoing Alzheimer's, leronlimab may stop it from occurring.
