Now, decades later, they were showing signs of Alzheimer’s. In the interim, scientists had discovered that that type of hormone treatment they got could unwittingly transfer bits of protein into recipients’ brains.

L ONDON — There was something odd about these Alzheimer’s cases. Part of it was the patients’ presentations: Some didn’t have the classic symptoms of the condition.
