Excerpt
An increasing number of studies have suggested that certain cases of iatrogenic Creutzfeldt–Jakob disease (iCJD) that harbor significant β-amyloid (Aβ) pathology are the result of aggregated Aβ transmission to patients during the same procedure that caused prion disease [

17]. The source of iatrogenic contamination has been observed both for human growth hormone infusions and dura mater grafts, arguing against a treatment specific effect. Intriguingly, recent work has also observed suspected Aβ pathology transmission in post-mortem samples that received growth hormone treatments but did not develop CJD [
17]. Yet another study suggested that neurosurgery with Aβ-contaminated tools can transmit Aβ pathology and lead to intracerebral hemorrhage [
12]. These findings have been debated in the context of whether Aβ pathology is truly transmissible and whether Alzheimer’s disease could subsequently develop. …
