A provocative new paper published in Nature suggests that neurodegenerative disorders such as Alzheimer’s and Parkinson’s may be transmissible through certain medical procedures. It’s an alarming claim—but one that will require more proof if it’s to be accepted by the scientific community.
We already know prion disease can be transmitted via surgical instruments. The supposition is prion diseases are more common and responsible for more neuro-pathology than we have given them credit for. There is no data or evidence – especially not a study of 8 patients who suffered from an incredibly rare neurodegenerative disorder which we don’t fully understand, to support this.
