Alzheimer’s disease may be transmissible from one person to another, but not in the way you might think, a shocking new study suggests.

Scientists have identified several patients who likely contracted Alzheimer’s through a now-discontinued treatment involving human growth hormone extracted from cadaver brains. While the findings don’t mean Alzheimer’s can spread like the common cold, they provide the first evidence that under rare circumstances, the disease may be transmissible between humans.

Why Is the Hormone Treatment Banned?

The implications of the study, published on Jan. 29 in Nature Medicine, are far-reaching for both past and future Alzheimer’s research.
