SCIENTISTS DOCUMENT FIRST-EVER TRANSMITTED ALZHEIMER’S CASES, TIED TO NO-LONGER-USED MEDICAL PROCEDURE

Summary from the TLDR newsletter

A decades-old treatment for a number of conditions that caused short stature, which involved patients receiving growth hormone taken from the brains of human cadavers, has been tied to some people as young as in their 30s developing Alzheimer's disease. The treatment, which was banned 40 years ago, transmitted unwanted proteins into recipients' brains, including the beta-amyloid protein that later propagated into the disease-causing plaques that are the hallmark of the disease. These are the first documented cases of transferred Alzheimer's - the disease is not usually contagious. The cadaveric growth hormone treatment has been long replaced with a synthetic hormone treatment.
