This article discussed a recent published paper about the possible transmission of Alzheimer’s disease by contaminated surgical equipment. This paper was publish in Nature whose impact factor is 41.577 in 2018. Clumps of amyloid-beta in the brain are a hallmark of Alzheimer's disease, although researchers still do not understand the relationship between these clumps and the degenerative brain disease. Between 1958 and 1985, about 30,000 children with growth deficiencies were treated with cadaver-derived human growth hormone (c-HGH) and three of them were diagnosed with Creutzfeldt-Jakob disease (CJD) c-HGH was subsequently abandoned and replaced by a synthetic form. Scientist found that c-HGH might be the true culprit behind the amyloid-beta deposits. We need to be careful while do blood transfusion and need to make sure that neurosurgical instruments are cleaned thoroughly. However, some scientists think this research is a very, very preliminary research and just looked at a buildup of amyloid in the brain but not the same thing as Alzheimer disease. Besides, some pointedly noted that animal findings often do not replicate in humans and does not mean that you can catch Alzheimer’s from another person.

I can't absolutely rule it out
it's unlikely to be much of a problem
clean those thoroughly
