Dr. James Galvin, director of the Comprehensive Center for Brain Health at UHealth, the University of Miami Health System, provided expert commentary on a story on a study revealing that cases of Alzheimer’s disease transmission in humans. “The cases were all very young onset, which would make one suspicious that there are extraneous factors involved. Typically, early onset is linked to genetic mutations, but as this was not found, the most likely common attributable cause would be the cadaveric growth hormone treatment. More investigation is needed,” Galvin, who was not involved in the study, said.
